Infographic: Fatigue and Work

See what you can do to manage fatigue at work

View Fatigue and Work Infographic

Fatigue is the state of feeling very tired, weary or sleepy because of too little or inadequate sleep, prolonged mental or physical work, or extended periods of stress or anxiety. Boring or repetitive tasks can intensify feelings of fatigue.

On average we need at least 7.5 to 8.5 hours of sleep every day. While it's always possible to reverse a short-lived or "acute" state of fatigue by catching up on sleep and rest, chronic fatigue may require a doctor's intervention.

Our latest infographic lists the telltale signs that you're tired, explains how it affects our health and safety at work, and offers tips for both workers and employers to help fight fatigue.

New WHMIS 2015 Resources Released

Get ready to transition to the new WHMIS

As Canada aligns the Workplace Hazardous Materials Information System (WHMIS) with the Globally Harmonized System of Classification and Labelling of Chemicals (GHS), also known as WHMIS 2015, amended legislation and new regulations are now in force.

A multi-year transition plan has been announced so that manufacturers, importers, distributors, and employers can get ready. Take steps with new resources from CCOHS.

Write WHMIS 2015-compliant Safety Data Sheets

CANWrite software updated to meet the new WHMIS requirements

Need to write safety data sheets? CCOHS has updated its CANWrite software to incorporate the requirements of WHMIS 2015. With CANWrite, you will be able to write a single 16-section SDS that complies with both the new Canadian Hazard Products Regulations (WHMIS 2015) and the US Hazard Communication Standard (HCS 2012) - this is a must if your products are going to used in both the US and Canadian markets.

This new version of CANWrite includes:

  • a combined WHMIS 2015/HCS 2012 classification worksheet
  • label elements from the 5th revised edition of the GHS purple book, as required from WHMIS 2015, as well as those required by HCS 2012
  • an Acute Toxicity Estimate (ATE) calculator
  • WHMIS 2015 and HCS 2012 Audits
  • guidance to help authors modify an SDS written for HCS 2012 to comply with WHMIS 2015

Affordable and easy to use, CANWrite will help you meet the challenge of writing and maintaining accurate, understandable, and compliant safety data sheets - whether those are for WHMIS 2015, HCS 2012 or for both systems at the same time.

The new CANWrite will be available in August.

Maximize Your Legislation plus Standards Service

Save time, stay on top of changes, and access standards

If you're a subscriber to our Canadian enviroOSH Legislation plus Standards service, here are three tips to get the most value:

  1. Access most cited CSA Group and CGSB standards, directly from the legislation. For the few standards that are not included, you can purchase them separately from our website.
  2. Use our monthly report to track legislative changes. The report is updated the first week of every month and provides a digest of amendments to health, safety, and environmental (HSE) legislation, the status of bills affecting HSE legislation, and new and repealed legislation and standards.
  3. We highlight the latest amendments to save you time. An amendment history is provided at the top of each legislative document after the citation and amended text is highlighted in purple to indicate where the changes have been applied.

As always, you can login to your subscription here, or access it through the LOGIN tab on our homepage.

Even if you don't have a subscription to our Legislation plus Standards service, you can still purchase individual CSA standards from our website. But with annual rates as low as $950, it may make more sense to be a subscriber.

Tips for Working in the Heat

Increased temperatures? Increase awareness

Whether you work in a hot smelting plant or outdoors in the summer months, heat exposure can be dangerous. Very hot environments can overwhelm the body's coping mechanisms leading to a variety of serious conditions.

Here are two posters to help workers cope with rising temperatures:

Keep Your Cool

Work safely in the outdoors. This poster is packed with safety tips for workers who take it outdoors in the sun and extreme heat.

Drink up, acclimatize, cover up, shield yourself, time your tasks right, and take breaks so you can keep it cool all summer long.

Heat-Related Illness: Watch for Signs

Heat exhaustion can quickly progress to heat stroke, which requires immediate medical attention - it can cause death or permanent disability if emergency treatment is delayed or not given.

It's critical that workers, managers, and supervisors all know the signs to watch for and to take action if the need occurs.

Featured e-Course: Accident Investigation

This course presents a practical approach to investigating workplace accidents, with an emphasis on how to find the root cause and prevent similar occurrences from happening again.
