Ergonomic Risk Factors and Injuries in the Office

Posted by in Uncategorized | May 27, 2021
Comments Off on Ergonomic Risk Factors and Injuries in the Office

There are multiple risk factors that can contribute to musculoskeletal injuries from exposure to ergonomic hazards while performing office work at home or in the office. What these risk factors all have in common is that they work to cause musculoskeletal disorders, psychosocial health effects, and reduce the quality of life outside of working hours. Risk factors come from many aspects of the workstation, task, and individual worker. They can be grouped into three main categories which are biomechanical, task-specific, and individual worker characteristics. When conducting an office ergonomic assessment for a workstation and task, the factors mentioned below are what are assessed, and controlled.

Biomechanical risk factors are present when workers perform tasks that require heavy lifting and/or excessive repetition, and awkward or static postures (1). These factors put excessive strain on the tissues of the body. Over time, the accumulated strain can result in an injury or the development of discomfort/pain. What all these factors have in common is that they remove the body from its neutral posture and loads are displaced unevenly throughout the body as a result. For excessive repetition to cause harm it does not require the lifting of heavy objects. Excessive repetition regardless of forces required to perform the movement can cause injury. One of the most common musculoskeletal disorder in the world is Carpal Tunnel Syndrome. Often this injury is associated with repetitive finger movements such as clicking and typing, in combination with compression of the wrist against a work surface. The repetitive motions result in the tissues becoming irritated and then inflamed, once inflamed the space in the carpal tunnel is reduced and the median nerve becomes compressed. The loss of sense and slight reduction in movement is a result of stress on the tissues of the wrist even though the actions require minimal amounts of force to be produced.

Task-specific risk factors include, workstation layout, high physical work, work that has high psychosocial demands, or work that requires prolonged use of visual displays. These factors are more closely associated to the requirements of the tasks being performed by the workers. Workstation layout is extremely important as it is a combination of furniture and organization of materials. A worker using a chair that has very low adjustability and support can remove the worker’s body from a neutral seated posture for extended or short and frequent periods of time. Combining a poorly suited office chair with a desk or work surface that is poorly organized can make the worker reach for items such as a mouse or keyboard. When reaching to use the mouse the worker is then in a static reaching position for a period of time which can put unhealthy stress on the tissues of the shoulder for example. Most of our working time when seated at a desk is spent using some type of visual display, being a cell phone or computer screen. Nowadays, we spend most of our time looking at a screen; without knowing the position of the screen in relation to our body plays a massive role in the risk of a musculoskeletal injury as a result of this.

Often forgotten but extremely important to consider is that workers come in all sizes. Therefore, there is hardly ever a workstation design that is a one-size fits all design. A common phrase to go by when designing a workstation or task setup is to “design it for the worker since you cannot design the worker to the workstation or task”. No two workers are the same thus when ergonomics are considered, individual worker characteristics such as smoking, a high body mass index, anthropometry, and other co-morbidities which include non-occupational related injuries are ergonomic risk factors too (1, 2). These factors are difficult to prevent from being introduced into the workspace, but their effects can be mitigated once identified. A worker’s anthropometry is an extremely important risk factor that must be considered. A workstation for a worker who is 5’2” should differ dramatically from a workstation for a worker who is 5’10”. If the workstation was designed for the taller individual in mind, the smaller worker will be required to reach or lean forward much more frequently for example. When a worker has to reach to perform their task, the risk of injury from exposure to an ergonomic hazard is significantly higher than a worker who does not have to reach to perform the same task.

This list of risk factors for exposure to ergonomic hazards is not fixed, as every situation presents other unique challenges and risks that are identified and assessed on a case-to-case basis. This is why it is extremely important to have objective and competent professionals performing ergonomic assessments.

Summary & Keywords

  • Ergonomics
    • Factors in the environment that can cause damage to the musculoskeletal system.
  • Objectives of Ergonomic Assessments
    • Identify risk factors
    • Quantify the risk
    • Control the risk
  • Three main risk factor categories
    • Biomechanical
      • Movements the worker performs while at the workstation or completing the task.
    • Task-specific
      • Characteristics of the workstation such as organization of items and materials, and the size of the furniture.
      • Psychophysical demands of the task.
        • Highly stressful tasks can cause muscle fatigue more rapidly leading to poor postures and headaches.
      • Use of visual displays.
        • The positioning of visual displays and the characteristics of them can cause workers to lean forward to read text, constant re-focusing when looking at a screen and documents. This can lead to neck, back, and eye strains.
        • High physical work.
          • This is deceiving as a task does not require constant movement of heavy loads or the generation of high forces to be considered high physical work. 54 – 75% of a working day is spent typing, that is a lot of movements in the arm and fingers. These repetitive low force movements do pose a risk of musculoskeletal injury to workers.
    • Individual worker characteristics
      • Anthropometry and Body Mass Index
        • Workers come in all different shapes and sizes, it is important to take this into consideration when designing a workspace or task.
          • Fit the task and workspace to the worker.
      • Smoking
        • Indirectly increases your risk of musculoskeletal injury as this affects many of the systems in your body.
      • Other co-morbidities
        • Disabilities resulting from injuries that are work or non-work related. If a worker has a previous non-work related injury and this impacts the way they should be normally performing the task, most often the worker will compensate for this by altering the movements the body. This change in movements may introduce new risks that were not present before the injury and require identification and control to prevent further injury.

Questions

  • How can I identify these risks in my workplace?
    • On our website www.tharris.ca we have a complementary video that walks our clients through what to look for to identify ergonomic risks at a workstation. If you are unsure always feel free to reach out to us at T.Harris Environmental Management with any questions and we will be very glad to help you with that.
  • Which of these risk factors is most important?
    • All of them are very important. Each workplace will have their own unique risk factors but the main group of risk factors that is consistent throughout any workplace are the task-specific risk factors. These factors are a combination of task requirements and workstation design.
  • Why are these risk factors important?
    • Most of these risk factors are work related but the effects as a result of exposure to them extend to life outside of work. Musculoskeletal injuries and other health effects that arise from ergonomic hazard exposure can seriously dampen an individual’s quality of life.
  • How do I know the pain the worker is feeling is from ergonomic hazard exposure?
    • First thing you ask the worker is, “Does the pain worsen as the week goes on, and lessens on the weekend or during time off?”
      • If they say yes, then this is an indication that the pain is a result of ergonomic hazard exposure during work related tasks.
    • Second thing you ask the worker is, “Do you feel uncomfortable at your workstation or while performing this task?”
      • If they say yes, this is an indication that the workstation or task requirements remove the worker from a neutral position for long periods of time or for short frequent periods. This can eventually lead to musculoskeletal injury development.

Benefits of Workplace Ergonomic Assessments

Posted by in Uncategorized | May 26, 2021
Comments Off on Benefits of Workplace Ergonomic Assessments

Ergonomic assessments are used in workplaces as a measure of risk relating to musculoskeletal injury development. Musculoskeletal injuries are estimated to cost the Canadian economy upwards of $22 billion each year (1). In developed economies such as Canada’s, nontraumatic musculoskeletal injuries incur direct and indirect economic costs of approximately $500 million per 1 million workers (2). To reduce this economic burden, ergonomic assessments can be one of the tools individuals and businesses can use to do so.

Currently, with the ever changing restrictions due to the COVID-19 pandemic, performing office work from home is becoming more prominent and normalized. Many workers may not have a designated office space that is setup similarly to that of their workstation in the company office. With this comes new challenges with regards to ergonomic hazard exposure and worker safety. Although new challenges arise, the responsibilities are unchanged; the responsibilities outlined in the Ontario Occupational Health & Safety Act still apply whether or not the worker is working from home or in the company’s offices. Therefore under clause 25(2)(h) of the Occupational Health and Safety Act, it is the employer’s responsibility to take every precaution reasonable in the circumstance to ensure the safety and health of their worker (3) . In these current situations, legally it is beneficial for the employer to have ergonomic hazard risk assessments of their employee’s workspace when working from home to ensure their safety and health is not compromised.

The goals of an ergonomic assessment are to identify the physical and psychosocial risk factors of the workstation and associated task, quantify the risk, and make the necessary adjustments to the workstation or task to minimize this risk. When thinking about workplace ergonomics, initially we think about three things. First, we think about lower back pain, which is then followed by sitting for long periods of time, then finally office chairs. In this case, lower back pain occurs as a result of exposures to ergonomic hazards; these include being seated in a static posture for a long period of time and the type of office chair being used. Although these are the risk factors, they can also be part of the solution. Assessing the current workspace furniture and tasks can help control the exposures to ergonomic hazards resulting in benefits for the user and the business.

To protect workers from ergonomic hazards, the magnitude of exposure must be identified, assessed, and then controlled. To do so, professionals in the field of occupational health and safety follow CSA Z412-17 Office Ergonomics – An application standard for workplace ergonomics. If done by an objective and competent individual, the benefits of an ergonomic assessment can be recognized at an organization level and at the individual worker level.

For the benefits an organization will see, studies have found that after ergonomic assessments and training are performed for workers on a whole the organizations observed (4–6):

  • Increased output per worker
  • Reduction in errors
  • Reduced accidents, injuries, and illnesses resulting in lost time
  • Reduced turnover and absenteeism
    • With this, there is a reduction in time spent training new employees
  • Reduced worker compensation costs

For the benefits the individual worker will see, studies have found that after ergonomic assessments or ergonomic hazard awareness training workers experienced (7–17):

  • Reductions in pain incidence or severity in multiple regions of the body
    • Lower back
    • Shoulder
    • Neck
  • Significant increase in overall ergonomic knowledge which led to lower rates of work-related musculoskeletal injuries

    • Sets requirements for Joint Health and Safety Committees in organizations dependent on employee populations.
    • Clause 25(2)(h) states the employer shall “take every precaution reasonable in the circumstance for the protection of a worker.”

Questions

  • Will I see the benefits of ergonomic assessments right away?
    • Yes and no. If an ergonomic assessment is done as a proactive measure before musculoskeletal disorders are present, the benefits may never be realized because worker injury has been avoided. If an ergonomic assessment is done as a result of a worker having developed a musculoskeletal disorder, the benefits at the individual level may be seen quickly as the pain they experience may be reduced dramatically. At the organization level, the benefits will be seen quickly as the pattern of productivity positively changes and the chance of the worker missing time due to injury is significantly reduced.
  • As an employer, why am I responsible for what the worker does at home?
    • Technically, if company policy provides the worker with the opportunity to work from home, their home is now a part of their workplace. Under clause 25(2)(h) in the Occupational Health and Safety Act, the employer is responsible to ensure the worker’s place of work is safe.
  • How do I know if a workstation requires an ergonomics assessment
    • All workstations should have an ergonomics assessment done to assess the risk. It is possible that the assessment concludes the current setup and task requirements pose little to no risk of musculoskeletal disorder development in the user. This information is still very valuable as it shows the company has been done their due diligence to ensure the worker is safe.

What is Ergonomics?

Posted by in Uncategorized | May 1, 2019
Comments Off on What is Ergonomics?

While talking to my friends, a group of healthy 20-25 year-old university graduates who have recently entered the workforce, I was surprised to learn how common back and muscle pain due to studying and deskwork had become. As all of us were joking about how we felt like we were unhealthy and working labour intensive jobs, I could not help but recognize that this is a serious yet neglected issue.

When we think of why body aches and pains have become so common, often the answer that comes to mind is awkward posture, or working for too long. While these are contributing factors, there are a wide variety of elements at play. A specific field of study, called ergonomics, actually addresses these concerns. Many of us have heard the term and perhaps just never paid much attention to it, until it is too late!

Whether you work at a desk or in a more physically demanding role or anywhere in between, T. Harris Environmental Management Inc. (THEM) can help make sure your work isn’t hurting you. If you have questions about how we can help, call us at 1-888-ASK-THEM.

WHAT IS ERGONOMICS ?:

In a nutshell ergonomics is the process by which any task is adjusted to fit the person’s physical and mental capabilities to alleviate stress and/or strain, and as such, avoid ergonomic related injuries. Ergonomics is not just limited to the position of your chair, or the placement of your desk. It can be applied to everything we do in life; even sleeping. Thus, when applying ergonomics in the workplace the task is fitted to the worker, and when designing consumer items the products are matched to the target users.


WHY IS ERGONOMICS IMPORTANT?:

Unfortunately, many of us take minor back pain, muscle cramps, and stiffness lightly, as it is commonly observed in many of our family and friends. Some of us choose to ignore it as “we just do not have time for it”.

However, pains and cramps due to poor/awkward posture, repetitive tasks, exposure to vibrations, and forceful exertions in labor intensive tasks, are a serious workplace hazard. In fact, lower back pain from poor ergonomically designed job tasks is a very common workplace injury, and in some parts of the world it is the most common work-related disability. This means that poor office ergonomics not only affects the employees long-term, but also reduces the overall productivity of the company, and thereby also reduces profits.  As an employer you may suffer direct and indirect costs, such as; increase in insurance coverage, loss of reputation/credibility, and in employee (turnover).

To put this into perspective, according to the Public Services Health and Safety Association (PSHSA):

  • 1 in every 10 Canadian adults has experienced Musculoskeletal Disorder (MSD) that has limited their normal activities.

  • 30% lost-time claims were due to MSDs in Ontario in 2016.

  • MSDs have been the most common type of work injury over the past 10 years.

 

T. Harris Environmental Management can help you make the most out of your workstation while keeping your staff healthy! Email us at info@tharris.ca to request a free consultation!

WHAT ARE COMMON ERGONOMICS ISSUES?:

Poor posture, repetitive tasks, and forceful physical exertions can lead to the development of a broad range of disorders called Musculoskeletal Disorders (MSDs), or Repetitive Strain Injuries (RSIs). Essentially, when our muscles, joints, and tendons are repeatedly exerted and stressed they eventually become damaged and can become irreversible. Thus, acute pain felt for a few hours can actually develop into serious and chronic problems.

Common examples of such injuries include:

  • Carpal Tunnel Syndrome

  • Back injuries

  • Tendinitis

  • Raynaud’s syndrome (White Finger)

ARE YOU SUFFERING FROM MUSCULOSKELETAL DISORDER?

Common symptoms experienced by workers include:

  • Swelling

  • Acute and chronic pain

  • Stiffness

  • Reduction in range of motion

  • Inflammation

  • Eye strains

HOW CAN I LIVE ANERGONOMICS LIFE?:

As an employer:

As work-related injuries due to poor ergonomics can substantially impact your employees’ wellbeing and company’s economic standing, investing in an Office Ergonomic Program can be highly beneficial.

An ergonomics professional, such as an Occupational Hygienist, can help create customized solutions to address your ergonomic concerns. This involves performing an in-depth review of all aspect of the environment that would effect a workers comfort, and also recommend control measures to prevent future injuries.

Services can include:

  • A thorough analysis of a worker’s environment; such as their

    • Job task

    • Frequency and duration

    • Lighting conditions

    • Tools/equipment used

    • Posture used and force exerted

    • Exposure to vibration and extreme temperatures

    • Reach and range of motion to commonly used items

  • A program that addresses worker’s unique needs and fit the task to each worker by following best practices published in reputable standards and guidelines.

  • Training that allows employers to become self-sufficient when evaluating the ergonomics of their day-to-day tasks, and provide recommendations for ergonomic work practices, such as lifting and stretching exercises.

EVERYONE WINS:

When your Occupational Hygienist completes your new Office Ergonomic Program you can expect benefits such as:

  • Increased productivity and efficiency

  • Increased overall health, well-being and employee morale

  • Decrease in work-related injuries such as MSDs

  • Decreased indirect and direct costs to employers

As an Employee:

Ask your employer if there is an Office Wellness and/or Ergonomic Program in place. Recognize signs and symptoms of MSDs and report them to your employer. If you notice there is a task/activity that is uncomfortable, let your employer know so they can adjust the task. Finally, follow recommendations on best ergonomic practices, such as taking regular breaks, for your health and safety!



With benefits like this, why wouldn’t you make the move for better workplace ergonomics?

Clear The Air: Addressing Exposure To Diesel Engine Exhaust

Posted by in Consultant Advice,Services,Uncategorized | August 9, 2018
Comments Off on Clear The Air: Addressing Exposure To Diesel Engine Exhaust

diesel exhaust

Managers are frequently aware of the risks of associated with some popularized occupational exposures such as asbestos and radon, yet few think about diesel engine exhaust is one of the potent risk factors for developing cancer. It is a serious concern: according to Carex[1], approximately 897,000 Canadians are exposed to diesel engine exhaust at work. This exposure occurs primarily in transportation-related occupations, including truck drivers, bus and subway drivers, locomotive engineers, and bus garage workers, trucking company workers, forklift operators, firefighters, garage attendants, traffic controllers, mechanics, taxi drivers, couriers and professional drivers. In fact, Health Canada[2] attributes an estimated 80% of particulate matter PM10 in the transportation sector to diesel engines. Other workplaces with a significant risk of occupational exposures include mining, construction, rail, farming and military.

 

The health effects and mechanics of diesel engine exhaust.

What exactly is diesel exhaust and what makes it dangerous? The International Agency for Research on Cancer (IARC)[3] has classified diesel engine exhaust as Group 1, which means it is carcinogenic to humans, based on sufficient evidence for lung cancer. The danger hides in the particulate matter contained in diesel engine exhaust.  Studies have shown increased rates of lung cancer when inhaling whole engine exhaust while other studies where the particulates were removed were inadequate to determine carcinogenicity.

The science and mechanics behind the results of the studies are somewhat complicated. Diesel engine exhaust (DEE) is a complex mixture[4] of substances characterized by polycyclic aromatic hydrocarbons (PAH) surrounding an elemental carbon core.  The gas phase chemicals present in diesel exhaust include nitrogen oxides carbon monoxide and volatile organic compounds such as benzene and formaldehyde. The particulate fraction comprises elemental carbon and organic carbon, ash, sulfate and metals.  Polycyclic aromatic hydrocarbons and nitroarenes are distributed within the gas and particulate phases. PAHs are easily absorbed onto the elemental carbon particulate, which has a large surface area, and are likely the cause of carcinogenicity for diesel engine exhaust.

Even a short-term workplace exposure to diesel engine exhaust can harmful to human health.  It can irritate the eyes, throat, and bronchi, and cause light-headedness, nausea, and respiratory symptoms. Moreover, diesel exhaust may initiate allergic reactions or increase immunological response to other allergens. Upsurges in hospital admission, higher incidence of respiratory symptoms, and decreases in lung function are all associated with exposures to airborne particulate matter, including diesel particulate matter.

 

Controlling diesel engine exhaust exposure.

Generally, employers must take all reasonable measures to keep workplace exposures to carcinogens to a minimum. Employees who may encounter confirmed carcinogens should be properly equipped to eliminate all exposure to the carcinogen or, if not reasonably practicable, to reduce it to the fullest extent possible. The quantity and composition of diesel engine exhaust emissions vary depending on the type of engine, the composition of the fuel and many other factors such as the use of a catalytic converter.


Ask THEM about developing a sampling strategy to assess occupational exposures to diesel engine exhaust in your workplace.

Call and speak to the experts.


Since diesel engine exhaust is such a complex mixture of chemicals, employers should consider engaging a qualified person (QP) such as a Certified Industrial Hygienist (CIH) or a Registered Occupational Hygienist (ROH). These QPs, including consultants with the above-mentioned designations, will help anticipate, recognize, evaluate and control workplace exposures to diesel engine exhaust. They have the expertise and experience to develop an effective sampling strategy for workplace assessment and recommend measures to control workplace exposures. Contact us for more details and a free phone consultation to get started.

More specifically, a QP will consider the following steps during an assessment:

1 . Development of an exposure assessment strategy: This includes choosing the right decision criteria for acceptable exposures. This could be OELs, DNELs or occupational exposure bands depending on the evaluated chemical.
2 . Basic Characterization:  The QP will gather information to characterize the workplace, workforce and environmental agents. This is where the assistance from the employer will be key.
3 . Exposure Assessment: assess exposure in the workplace by grouping workers into similar exposure groups (SEGs) and evaluating all applicable exposure routes (dermal, inhalation, ingestion).
4 . Prioritization: prioritize exposure monitoring or collection of more information based on health effects and exposure risk
5 . Implement prioritized control strategies for unacceptable exposures using the hierarchy of controls
6 . Verification: Reassess to verify that acceptable exposures remain acceptable.
7 . Documentation: Communicate and document results.

Risks associated with antineoplastic agents.

Posted by in Uncategorized | July 16, 2018
Comments Off on Risks associated with antineoplastic agents.

With chemotherapy as one of the main cancer treatments, there is a global increase in the use of antineoplastic agents. Antineoplastic drugs, also known as cytotoxic drugs, are most often used in chemotherapy to treat cancer.   While they are used to treat cancer patients, they can be hazardous to healthy workers in health care, pharmacy, veterinary clinics and cleaning staff.   They have a toxic effect on cells within the body and there is no safe level of exposure to these cancer-causing agents. As a result, there is a need to implement rigorous health and safety practices with regard to these drugs. The OHS concerns are as follows:

  • Many antineoplastic drugs are carcinogenic;
  • Chronic issues can show up many years later;
  • Acute reactions can include skin irritation, eye and mucous membrane irritation, nausea, vomiting, hair loss and rashes;
  • Issues can include damage to the liver, kidney, lung and heart;
  • These drugs can affect fetal development.

Workers who may be exposed to cytotoxic drugs have to be aware of all of these risks, receive relevant training, use the engineering controls provided and wear all necessary personal protective equipment (PPE) to protect themselves. There are many exposure routes to take into account:

  • Skin absorption (direct contact with the drug or indirect contact with contaminated surfaces, clothing or handling patient excreta);
  • Inhalation (breathing in drug vapours or dust);
  • Accidental injection (needles or other sharps that puncture the skin); and
  • Ingestion (eating, drinking or smoking with unwashed hands or hand to mouth touching).

OHS Program basics.

Working with cytotoxic drugs requires strict policies and procedures. Every employer using cytotoxic drugs in their facility should at least consider the basics such as outlined below.

The right equipment. Engineering controls may be required including primary containment such as Biological Safety Cabinets or Isolator Cabinets and secondary containment for pharmacy dispensing and needle safety devices to prevent needle sticks.  The PPE needs to be easily accessible and workers need to be trained on how to properly use the equipment as well.

Training and good communication about the types of hazards workers may encounter is also very important.  Administrative controls such as worker training on hazards of chemotherapy drugs, proper use of engineering controls and standard operating procedures have to start from the very beginning with a comprehensive orientation and it has to include everybody, from shipping and receiving to front-line workers and managers.  Furthermore, workers need to receive training in all of the emergency response procedures for the variety of scenarios that could occur. Both the training program and the Occupational Health and Safety Control program should clearly identify the emergency procedures to follow in case of accidental exposure to cytotoxic drugs and/or in a spill response operation.

Monitoring and professional oversight are key to bringing all of the above elements together in a meaningful way. Employers should establish a comprehensive Occupational Health and Safety Control program, encompassing all of the aforementioned aspects, to protect both the workers and reduce their business risks. Occupational Health and Safety professionals recommend conducting exposure monitoring on a regular basis to ensure workers are not exposed and work surfaces are not contaminated. Ideally, an employer should involve a Certified Industrial Hygienist (CIH) or Registered Occupational Hygienist (ROH) to assess and develop a comprehensive program to minimize the possibility of missing a potential hazard.

Keeping Your Cool: Best Practices For Working Safely Under Extreme Temperatures

Posted by in Consultant Advice,Services,Uncategorized | June 5, 2018
Comments Off on Keeping Your Cool: Best Practices For Working Safely Under Extreme Temperatures

Nice weather has finally arrived and many workers are feeling the heat. It is now the season to expect heat-related illnesses in the workplace. Summer may put many workers at risk of heat stress and seriously injure them. A series of hot and humid days following one another may adversely affect workers who did not previously acclimatize to heat exposure.   Extreme heat directly affects the health of workers, puts their safety at risk with impaired judgment and reduces productivity. This is a significant issue not only for occupational health and safety of people but also for the effectiveness of an organization as a whole. While Heat Stress Prevention Plans are complex and their development is better left to the professionals, every responsible supervisor should know some key facts to manage work in extreme heat on a daily basis.

Did you know?
Loss of consciousness because of heat stroke is classified as a critical injury and is a reportable event under the Occupational Health and Safety Act.  

Who is most susceptible to heat stress?

Fortune examined the sectors with the highest risk of heat stress and found that the sectors highest on the list were those with a lot of outdoor work. The top three are workers in government services, agriculture, followed by construction and business service. Government services included workers who maintained parks, fought forest fires and collected trash. Other professions who are inclined to suffer seasonally from this hazard include military personnel, landscapers and hazardous materials abatement contractors. Employers should also look out for new workers on the job. New unacclimatized employees working in manual occupations and ‘young workers’ who may not realize the risks are most vulnerable to extreme heat.

Important note:
There is a range of heat illnesses and they can affect anyone, regardless of age or physical condition.

What contributes to heat-related illness and how to mitigate the hazard?

Environmental factors such as high temperature, high humidity, and radiant heat sources such as direct sunlight, ovens, boilers, steam pipes and engines can contribute to heat stress.  The best way to remedy this is to make the work environment cooler through engineering control measures such as convection, radiant or evaporative heat control measures.

Did you know?
Just 30 minutes of exposure at the temperature of 40 C is enough to cause permanent disability or brain damage.

Administrative controls such as limiting exposure times or temperature, reducing metabolic heat load, enhancing tolerance to heat, screening for heat intolerance, health and safety training and instituting a heat alert or hot weather program are suggested.  Equally important are ensuring personal hydration, acclimatization of employees, controlling work duration times and monitoring the levels of physical exertion as key components of combatting heat-related illnesses. It is considered the next best method to protect workers because it allows employers to proceed with work without eliminating the source of the danger.

Conjointly with administrative controls, Personal Protective Equipment must be reviewed. PPE and protective clothing is the third level of protection from heat stress. Selecting the proper PPE for each situation can dramatically lower the effects of heat – and it is not the only reason to review all PPE use. In hot conditions, PPE that protects workers from other hazards may become uncomfortable and workers may then avoid wearing it. This is an issue that consultants frequently encounter when conducting inspections on job sites. For example, abatement contractors working in enclosures may avoid wearing a full-face air-purifying respirator in hot conditions where a powered air-purifying respirator that provides airflow across the face will be more comfortable.   The impermeable clothing required for abatement work prevents heat exchange from the body to the environment and contributes to heat burden.   Auxiliary body cooling may be required in the form of water-cooled or air-cooled garments or cooling vests.

There is no standard set of measures to prevent heat-related illnesses, so the best solution to comply with regulations and keep workers safe is to establish a Heat Stress Prevention Plan unique to each project or workplace (Ask THEM for assistance). Many physical factors affect the solutions that will be implemented: the age of workers, their state of health and physical fitness, required work tasks and personal protective equipment, as well as available resources – all play a role in finding the right solution. While each situation is unique, all plans share these common elements:

  • Methods to monitor temperature and humidity levels.
  • Description of conditions when heat stress measures should be implemented.
  • Outline of engineering controls and administrative controls.
  • Outline of proper PPE/clothing.
  • Emergency response measures.
  • Training requirements for all workers and supervisors that include the signs, symptoms and prevention of heat stress and how to deal with those risks.

Heat Stress in Indoor Environments

Although heat stress is typically associated with seasonal outdoor work environments, heat can be a year-round hazard in indoor workplaces. Commercial bakeries, kitchens, laundries and environmental abatement sites are just some activities that may be affected. In these workplaces, workers are often near sources of radiant heat or inside buildings with limited cooling capabilities and air movement.

Common question:
Should an individual in an indoor work setting use the same preventive measures for heat stress as someone working in an outdoor setting?

Measures to prevent heat-related illness are similar in both indoor and outdoor environments, but indoor workplaces have additional concerns.  For example, an indoor environment with little airflow may diminish the cooling effects of that sweat provides through evaporation. Nonetheless,  these environments also provide additional opportunities to use engineering control measures.  As with outdoor work environments, it is important to develop a prevention plan to handle the potentially hazardous indoor heat.

Underground Storage Tanks: Finding The Good, The Bad and The Ugly

Posted by in Consultant Advice,Services,Uncategorized | May 4, 2018
Comments Off on Underground Storage Tanks: Finding The Good, The Bad and The Ugly

When warm weather sets in and the real estate season starts, it is the perfect time to detect and assess underground storage tanks (USTs). Underground storage tanks are typically made of bare steel and were an efficient method of fuel storage used in the 1980s and early 1990s [1]. However, the conditions of soil can corrode the bare steel over time and thus lead to the leakage of content from the tank.

Sellers, buyers and property managers can all benefit from proactive UST management or removal. It helps sellers protect the value of their property by ensuring that they are compliant with the laws and that they have addressed any potential risk of contamination. As per the Technical Standard and Safety Authority (TSSA), all existing USTs must be registered with the TSSA and any unused USTs must be properly removed within 2 years by a licensed contractor [2]. For buyers, ensuring that there are no faulty USTs and/or contamination is a prudent strategy to minimize their risk of buying a “lemon” property.  For ongoing management of the property, it is one of the ways to reduce the risk associated with contamination, and consequently, avoid the loss of property value.

Tell-Tale Signs of a UST

Consultants often find that some property owners or managers are unaware of existing USTs at their property until specific events, such as piping inspections, occur. If a property manager knows whether they have an existing UST sitting in their backyard, they are already ahead of the game!

To determine whether a property may have an unregistered UST, T. Harris Environmental Management Inc. (THEM) suggests the following tips and procedures for managers and owners that are unsure whether a UST is present on their property:

  • Property owners and managers could look for available past records (if any) and/or environmental reports concerning the property for any indications of USTs. Records can be requested from TSSA. Having no records may not always mean that there is no UST on the property.
  • Perform a historical review of the building’s records. USTs are often built for the purpose of building heating. Having a comprehensive history of the heating source and the time that the current HVAC system was installed may indicate whether a UST is present.
  • Perform an exterior building walk around, look for any signs of the following:
  • Unused steel pipes coming out of the ground and going into the building. This could be a transfer pipe of the UST.
  • Broken asphalt may indicate the presence of a large object underground. During seasonal changes, soil temperature may cause the soil to expand and potentially make the UST ‘float’ up in the soil.

THEM has an experienced environmental team that specializes in Underground Storage Tank assessment, removal and remediation in institutional, commercial, residential and industrial sites. Contact THEM for a pre-consultation if the above UST tips were not sufficient to alleviate your doubts about having a UST on your property.

The economic benefit of addressing UST issues

Proactively addressing UST – related issues promotes safe fuel storage, protects the environment and reduces costs in the long term. This is accomplished by ensuring that a company’s actions to mitigate contamination comply with all environmental requirements. Proactive managers benefit from risk reduction. An unregistered abandoned UST tank is not only a violation of regulations but could also reduce property value when it is discovered during a due diligence ESA.

Time is a crucial component: the sooner an ageing and corroding UST system is upgraded or removed – the greater the likelihood that a costly tank leak can be prevented. Therefore, property owners can reduce their financial risks, exposure to enforcement from environmental regulators, and protect themselves from litigation with adjacent property owners (who would otherwise be affected by a leaking tank).

UST assessments in areas prone to extreme weather provide further opportunities to reduce risk. UST systems can be vulnerable to damage and may leak contaminants during extreme weather events. Before returning a UST to service after a disaster, the owner needs to ensure the system is safe to operate. As a result, USTs usually require pre-emptive actions prior to the extreme weather event and an inspection after the event, which is becoming increasingly more common.

Maintaining or removing USTs can reduce the risk of vapour intrusion, and consequently, help avoid the costs associated with addressing it. Vapour intrusion occurs when contaminants infiltrate from subsurface sources into indoor spaces of a building. This can occur if leftover substances in the UST, such as gasoline, diesel, or jet fuel, turn into petroleum hydrocarbons and enter a building as vapours. Preventing such intrusion helps improve safety (e.g. avoid explosions) and possibly adversely affecting the health of building tenants. Well-water and vapour intrusion are probably the most critical threats to human health from UST releases.

The social benefit of addressing UST issues

Maintaining or removing USTs is more than compliance and risk reduction – it is a socially responsible and sustainable thing to do. It can benefit human health, improve ecosystem functions, add to aesthetic values, and make land more productive. Cleanup of UST contamination potentially increases the amount of urban land available for redevelopment, and it can reduce the pressure for development of new land parcels. This can help preserve green spaces and shorten commute times. Taking care of USTs also reduces human exposure to contaminants. It results in reduced health risks to employees as well as nearby residents, who may consume well water or become exposed to vapours. To top it all off, old UST sites such as vacant gas stations with suspect contamination, are often visually unappealing and reduce the desirability or curb appeal of that site or area. Restoring such a site can make the community and businesses around it flourish, earning the company who did it a portion of goodwill.  These are just some of the benefits of taking care of USTs – and it all starts with being proactive in the detection and assessment of USTs.

Don’t Give a Cold Shoulder to Indoor Air Quality (IAQ) Management

Posted by in Consultant Advice,Services,Uncategorized | March 26, 2018
Comments Off on Don’t Give a Cold Shoulder to Indoor Air Quality (IAQ) Management

Maintaining good indoor air quality is often a challenge during spring and fall. The increased likelihood of poor IAQ during shoulder seasons is a result of a combination of poor ventilation, moisture and airtight insulation in buildings. The HVAC’s primary purpose is to maintain good indoor air quality and adequate air supply.  During the shoulder seasons, it is on average neither hot nor cold, so the HVAC is not activated by the thermostat to correct the temperatures. As a result, the building may not receive a sufficient daily circulation of fresh air and accumulate pollutants from repair projects, cleaning procedures and simple daily activities.

Poor Indoor Air Quality can have consequences ranging from loss of productivity in the workplace to serious health challenges for building occupants. Eye and upper airway irritation are a common result of poor IAQ and are among the top symptoms reported in office questionnaire studies. To maintain optimum health it is important to lower the concentrations of indoor air pollutants in your environment. There are two ways of achieving this: to eliminate the source of indoor air pollution and to increase the amount of incoming clean air.

Eliminating the sources of indoor air pollution:

  • Monitor humidity and water infiltration: Dry Air, Mould & Bacteria

Regulating humidity levels will help make tenants comfortable and minimise health issues. During shoulder season, testing your IAQ will help monitor the environment for the development of mould allergens associated with high humidity levels and help prevent problems of dry skin, airways, and lips associated with low humidity levels. If you suspect mould you can visually assess your building and have your IAQ tested for mould spores. The correct level of humidity also prevents cracks in wood, helping the building and furniture in it last longer. To keep humidity within comfort ranges, the building should have humidity sensors in the thermostat or a separate hygrometer system that can control humidification separately.

  • Consider your building materials: VOCs, asbestos, formaldehyde and lead

In addition to passive health and comfort concerns, spring is the season for renovations and property maintenance. Make sure you know the building materials and property issues so that you avoid exposing building tenants to further health risks. Some building materials may contain substances such as asbestos and lead that pose a health risk if they are disturbed or improperly handled. New materials that are installed in the building may also contribute to indoor air pollution by off-gassing formaldehyde and other Volatile Organic Compounds. To learn more about VOCs and Designated Substances, visit our Hazardous Materials page.

Increasing the amount of incoming clean air:

Studies have found significant direct effects of ventilation rates on health and on increases in some allergy and asthma symptoms in buildings with less ventilation. Another study estimated that increases in building airtightness without compensating measures could increase indoor radon concentrations by 57%.

  • Create a sufficient exchange of clean air

Improving ventilation with outdoor air can make IAQ better, but only if the incoming air is cleaner than the indoor air. Often this is not the case, and ventilation worsens IAQ. Poor outdoor air quality can be a result of elevated outdoor contaminant levels, motor vehicle exhaust from nearby roadways and contaminants from adjacent buildings. In these cases increased air ventilation may be counterproductive unless it is accompanied by the appropriate and effective increase in air filtration and cleaning.

  • Consider IAQ during building performance improvements

Building owners and managers often miss the opportunity to improve IAQ and energy efficiency during routine renovations. Renovations are a great opportunity to improve IAQ if it is integrated into the project. Yet, efforts to achieve high levels of building performance without consideration for IAQ can lead to problems. Some common measures that can potentially affect IAQ are envelope tightening and the addition of insulation to the building envelope, all of which reduces air ventilation. A consultant can help evaluate the IAQ needs for your project or at the very least tell you if it is necessary to consider a consultation.

  • Keep pesticides, pollen & other outdoor pollutants in mind

Spring is the season for increased allergen levels in the outdoor environment. Paying close attention to the substances and plants in your landscape can also help with indoor air issues. Building managers often overlook the fact that every time a door opens in the building, outdoor air pollutants such as pollen enter the building’s air supply. Therefore, plants and pollutants near your building can affect tenant health. Managers should evaluate landscaping and vent placements to determine what is potentially entering their building. Additionally, you can integrate low-allergen plants and fertilizers to make sure tenants are protected.

  • Maintain your HVAC system

Everything in the building air will eventually end up in the indoor air duct system, caught in the air filters of the HVAC system or built up inside the HVAC system itself.  As a result, a poorly maintained HVAC system may introduce pollutants every time it starts. This is a particular concern in spring and fall since the system starts and stops more frequently. To safely remove the accumulated debris, maintain your HVAC system and change filters frequently.

Tips to address floods and water damage

Posted by in Consultant Advice,Services,Uncategorized | March 26, 2018
Comments Off on Tips to address floods and water damage

 

Floods and the associated water damage that often follows can be unexpected and often times devastating financially. When water finds its way into a building as a result of precipitation or a mechanical failure, it can be a challenging experience both emotionally and financially. If severe flooding occurs, it is important to act quickly and effectively mitigate any damages. While it is tempting to wait and see what happens or to try to fix the situation on your own, it is important to know how a professional can assist in addressing flood and water damage right away.

Tips for mitigating against further damage:

Moisture only needs a few hours to cause critical damage to materials in a home or workplace. When any type of water loss or damage occurs, the amount of time a material stays wet is the most crucial factor in determining the damage sustained, and whether or not the material can be restored. The longer you wait – the more damaged your property can become! Responding quickly decreases the likelihood of substantial mould growth, which can further damage the building materials and cause potentially adverse health effects to building occupants.

Flood waters and sewage backups are a health risk, as they may carry with them a lot of bacteria, viruses, and fungi. Any contact with these microorganisms can be especially dangerous for at-risk building occupants such as seniors and children. If the water is contaminated, it is safer to let professionals handle the cleanup. Professional companies possess the proper safety equipment for these situations and are trained on how to protect both themselves and the building occupants from these hazards.

Learn more about Mould and Floods

Choosing a qualified water damage professional:

In addition to contacting your insurance company, the first call to make in a water damage situation should be to a qualified water damage professional service. Finding a company that can respond quickly, provide a full range of services, and is available 24/7 is the first crucial step in response to any water damage or flood situation. Water damage professionals have an extensive selection of technology at their disposal. They are equipped with specialized vacuums and pumping systems, dehumidifiers, air movers and moisture metres to assess and effectively dry building components, and chemicals required to destroy mould and fungi growth. To ensure quality of work, choose IICRC-certified water damage professionals. IICRC (Institute of Inspection Cleaning and Restoration Certification) assures the company possesses the most up to date training and is equipped with the knowledge and skills to effectively handle your specific situation. The IICRC maintains a Certified Firm registrant-only database, making it easy to find a professional in your neighbourhood.

This will help outline the specific scope of work for the restoration contractor and ensure all the necessary work completed without any extras. Additionally, EHS professionals can also provide post-remediation testing and analysis ensure the effectiveness of remediation and restoration activities. This gives you both records of completed work, as well as the peace of mind that your home or building was restored quickly and safely.

National Pollutant Release Inventory (NPRI): What is it?

Posted by in Uncategorized | February 28, 2018
Comments Off on National Pollutant Release Inventory (NPRI): What is it?

The National Pollutant Release Inventory (NPRI) is Canada’s legislated, publicly accessible inventory designed to track and catalogue the release of pollutants, their disposal, or their transfer to recycling facilities. Every year on June 1st, facilities nationwide are subject to compile information on the following pollutants: air contaminants, pollutants released in water, and waste products disposed on land. The NPRI oversees the usage of over 300 unique substances Canada-wide and over 7000 facilities were included in the registry last year alone.

Do you need to register?

Facilities in every province and territory across Canada are responsible for registering with the NPRI if they meet certain conditions, such as:

  • If one (or more) designated NPRI substance is manufactured, processed, or otherwise used at the facility during the year.
  • If the total working hours accumulated within the facility is greater than 20,000 hours. This is equivalent to approximately 10 full-time workers over the calendar year.

If a facility you own or manage meets these conditions, you must register in accordance with Federal Law. Additionally, facilities involved in incineration, wood preservation, terminal operations (among others) must adhere to NPRI reporting requirements regardless of employee hours worked.

If you have any doubts about whether or not your facility requires registration, contact a professional. Industry professionals have in-depth knowledge of the NPRI database and the over 300 substances that it encompasses.

Unsure if you require registration? Contact THEM to find out.

The Importance Of Filing The NPRI With a Professional

Environmental consulting professionals possess a vast knowledge of NPRI reporting requirements and can streamline the reporting process to ensure it is handled in a quick and orderly fashion. For instance, facilities may be required to report based on Concentration Threshold, Mass Threshold, Employee Threshold, and Activities/Sector. The reporting criteria are different for each section. Failure to meet the reporting requirements or reporting deadline may result in fines and penalties.

Environmental specialists follow a number of steps to ensure all issues are dealt with in a timely fashion. A brief overview of the steps taken include:

  1. Determining the substances that a facility uses that may fall under the NPRI catalogue.
  2. Verifying the total quantities of substances a facility manufactures, processes, or otherwise uses in a calendar year.
  3. Establishes whether the use of these substances surpasses the NPRI reporting threshold.
  4. Ensures the appropriate reporting procedure is followed for all substances over the threshold.
