Heat-related health and safety hazards increase when temperatures rise, and workers and employers must take precautions to prevent serious medical distress.

Actsafe has compiled some resources for workers and employers to use when crews are scheduled to work outdoors in extreme hot weather conditions.

The Canadian Centre for Occupational Health and Safety’s Working in Heat infographic packs lots of useful information into a small package to help employers protect workers from heat stress.






Actsafe’s Safety Bulletin on Working in Extreme Hot Conditions is also a valuable resource for workers and employers alike.









As part of Actsafe’s upcoming Online Safety Awareness Course, we have produced a number of videos dealing with hazards workers may encounter on the worksite.  Click on the image below to watch our video on working in extreme hot conditions to find out what to look for when workers may be in a heat-related emergency, and what to do to protect them and yourself.







WorkSafeBC’s Heat Stress resource page also has information available to help workers and employers deal with working outside in high temperatures. Click on the image below to see what they have to offer.










The National Institute for Occupational Safety and Health (NIOSH) has developed a great smartphone app that can tell you what the heat index is in your area, what the signs and symptoms of heat stress are, and what first aid treatment should be administered to someone suffering from a heat-related emergency. The downside of this app? Heat indexes are only automatically available for locations in the United States.  If you’re located in Canada, you can manually enter the temperature and humidity (simply check your built-in weather app for these details) without inputting a location. Check out the app, available for iOS and Android devices, by clicking on the image below.








The bottom line is that working in hot temperatures for an extended period of time can lead to serious medical emergencies.  If you find that you are working outdoors in these conditions, make sure you:

  • Drink plenty of water even before you feel thirsty and stay in a cool place.
  • Seek a cool place such as a tree-shaded area or air-conditioned spot like a public building.
  • Take regularly scheduled breaks out of the sun, in a cool place.
  • Notify your supervisor and seek medical assistance if you suspect you may have the symptoms of heat illness.
