This topic includes a wide range of injuries that can occur in the workplace if your work is not set up and managed properly and safely. From ergonomics to musculoskeletal disorders to your work environment, we cover all the bases when it comes to occupational injury prevention. We encourage you to explore the topics below as well as the many services and resources we offer related to each.

Every Injury is Preventable

Prevention programs are a proactive way to find and fix workplace hazards before workers are injured or become ill. These programs can be effective at reducing injuries, illnesses, and fatalities. Musculoskeletal Disorders, Work Environment and Workplace Ergonomics are all key topics of the prevention picture.


By definition, ergonomics is the study of the relationship between workers and their work environment.

The aim of ergonomics is to match the job to the worker to reduce the strain placed on the tissues and to prevent injury.

We provide information and resources on both office ergonomics and industrial/commercial ergonomics


The environment in which your work can adversely affect your health and well-being.

From noise to temperature and lighting, it is important that all aspects of your work environment are suitable
for the tasks that are being performed as well as the people that are performing them.


When a muscle, tendon, nerve or joint is stressed and traumatized on a repeated basis for days, months or years, those body tissues eventually become damaged.

This leads to a work-related musculoskeletal disorder (MSD).

Musculoskeletal disorders (MSDs) are the most common type of workplace injury in Ontario workplaces. They can occur throughout the body including the head, neck and back as well as in the upper and lower extremities. It is crucial to control the hazards that could leads to MSDs.

Indoor Air Quality



We all experience sound and noise in our daily life, normally at a safe level that does not damage our hearing. However, sound can be extremely harmful when at too high a frequency and when experienced over a long period. Learn more about the types of noise, noise limits and the effects of prolonged exposure to high levels of noise with our wide range of resources. Learn more about NIHL on our  Noise-induced Hearing Loss page.


Proper lighting in your work space is essential to both your health and safety. Insufficient or improper lighting can cause eye strain leading to headaches, even migraines.
It can also cause accidents due to poor visibility. Use the following resources to learn more about the importance of workplace lighting:


Heat / Cold

Workers are often employed in environments, both inside and outside, which may involve exposure to both cold and hot temperatures. Understanding the health risks involved with working in extreme temperatures can help employers protect their workers. From heat stress and sun stroke to hypothermia and snow shovelling, we cover a wide range of health effects with valuable resources. Learn more on our Working in Heat/Cold Extremes page.


“Sick Building Syndrome”

Indoor Air Quality is an important component of your work environment. Poor indoor air quality can lead to headaches, fatigue, eye, nose, throat and skin irritations as well as the spread of colds and the flu. It can also be responsible for Building-Related Illnesses (BRI) such as Legionnaires’s Disease, Pontiac Fever, Aspergillosis, SARS, Tuberculosis, Rubeolla.
