Heat stress safety: A timely reminder
With temperatures climbing above 30°C this week, (and high humidity making it feel even hotter), it’s a good time to revisit how heat can affect us, and what we can do to stay safe.
How heat can affect us
Working in hot environments can lead to heat exhaustion or, in more serious cases, heat stroke. It’s important to recognize the signs early:
Heat exhaustion may include:
- Heavy sweating
- Dizziness or weakness
- Headache or nausea
- Cool, moist skin
Heat stroke is a medical emergency. Watch for:
- Hot, dry skin
- Confusion or disorientation
- Fainting or loss of consciousness
- A body temperature of 40°C or higher
If you or someone nearby shows signs of heat stroke, call 911 immediately.
How we can stay safe
There are simple, proactive steps we can all take to reduce the risk of heat-related illness:
- Drink water regularly—don’t wait until you’re thirsty
- Take breaks in shaded or air-conditioned areas
- Wear light, breathable clothing and a hat when outdoors
- Apply sunscreen to avoid sunburn
- Use the buddy system to check in on each other
- Let your supervisor know if you’re not feeling well or need a break
If you’re returning to hot work conditions after time away, remember it can take 1–2 weeks for your body to acclimatize. During that time, increase hydration, take more frequent breaks, and listen to your body.
Working in the heat doesn’t have to be dangerous - as long as we stay informed, act, and look out for one another.
Stay safe, stay hydrated, and take care.
