Staying safe while working in the heat
As summer temperatures climb, working in the heat can take a serious toll on our bodies and health. Whether we’re outside under the sun or indoors near heat-producing equipment, it’s important to recognize the risks of heat-related illnesses—and know how to protect ourselves and our coworkers.
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 know the signs:
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 high body temperature
If you or someone nearby shows signs of heat stroke, call 911 immediately.
How we can stay safe
There are steps we can take to stay safe and prevent heat-related illnesses:
- Drink water regularly – don’t wait until you’re thirsty
- Take breaks in shaded or cooler areas
- Wear light, breathable clothing and a wide-brimmed hat if working outdoors
- Use sunscreen to protect against sunburn
- Watch out for each other – use the buddy system to check for signs of heat stress
- 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 that it takes about 1–2 weeks to acclimatize. During this period, take extra care to stay hydrated and take breaks more frequently. Be patient with yourself and others while our bodies adjust.
Working in the heat doesn’t have to be dangerous—as long as we stay informed, take action, and look out for one another.
Stay safe, stay hydrated, and take care.
