Indoor Air Quality

A safe and healthy work environment is good for your workers as well as your business as it improves job satisfaction, productivity and reduces costs related to absenteeism, turnover, workers’ compensation, and medical claims.

Learn more about the importance, benefits and how to improve your work environment using the following topic-specific resources:


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:

Noise-Induced Hearing Loss (NIHL) Audiogram Calculator

Updated August 2021

Designed to assess values based on the worker’s audiogram to clarify if their NIHL meets the minimum requirement for establishing a NIHL claim with the Ontario Workplace Safety and Insurance Board (WSIB).

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:

Office Ergonomics – Lighting

A section of our Office Ergonomics Reference Guide is devoted to the topic of lighting including the various types of lighting, dealing with glare, work surfaces, etc.

Office Ergonomics – An application standard for workplace ergonomics*

Canadian Standards Association (CSA) Z412-17

The objective of this Standard is to apply ergonomics to enhance user health, safety, and well-being and to optimize system performance in order to prevent occupational injuries and illnesses or to reduce the severity of harm related to occupational activities in offices.

Heat Stress Awareness Guide

Cover of the WSIB Heat Stress Awareness Guide

An in-depth guide to help employers and worker learn how to prevent heat stress by summarizing the causes, symptoms, and treatment of heat-related illness.

Humidex-based Heat Response Plan

A simplified way of protecting workers from heat stress which is based on the 2009 ACGIH Heat Stress TLV® (Threshold Limit Value®) which uses wet bulb globe temperatures (WBGT) to estimate heat strain. These WBGT’s were translated into Humidex.

“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.

Use the following resources to learn more about the causes, effects, and prevention of Sick Building Syndrome by improving indoor air quality using the following resources:

Doing Something About Indoor Air Quality

A presentation by John Oudyk, MSc, CIH, ROH, OHCOW Occupational Hygienist, covers thermal comfort, ventilation, contaminants, investigation techniques, personal health factors, stress and prevention resources.
