Infographic: Fatigue and Work

See what you can do to manage fatigue at work

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

CANWrite webpage

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.

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.
