Environment Canada has issued a warning about the first significant heat event of the season, with dangerously hot and humid conditions expected to persist throughout the week.
Daytime temperatures in some areas are forecasted to reach between 29 and 33 degrees Celsius, with humidity making it feel closer to 40 degrees.
Officials urge everyone to take action to protect themselves and others, as extreme heat can affect everyone’s health. They recommend assessing if you or those around you are at greater risk of heat illness.
Construction workers are particularly vulnerable to direct sunlight and humidity exposure. Early warning signs of heat exhaustion include headache, nausea, dizziness, thirst, dark urine, and intense fatigue.
To prevent heat-related illnesses, drink a cup of water every 20 minutes and wear light-colored clothing when working in such conditions.
If you are concerned that employers are not taking appropriate steps to help workers avoid heat stroke and exhaustion, contact your business representative.
