Outdoor crews and many indoor workers face the risks of heat cramps, heat exhaustion, and heat stroke during periods of dangerous heat. Recognizing symptoms and documenting conditions can help prevent serious harm.
Heat illnesses to watch for
- Heat stroke is an emergency. Confusion, fainting, seizures, and extremely hot skin require immediate action and a call to 911.
- Heat exhaustion may cause heavy sweating, headache, dizziness, and nausea.
- Heat cramps and heat rash can be early warnings that conditions are unsafe.
Workplace precautions
- Access to cool water, rest breaks, and shade or cooling.
- Training to recognize symptoms and emergency procedures.
- Gradual acclimatization for new and returning workers.
- Active monitoring when the heat risk is elevated.
Practical steps for workers
- Speak up when you or a co-worker shows symptoms.
- Hydrate frequently and take breaks in a cool area.
- Use a buddy system during high-risk periods.
- Document temperature, schedules, and a lack of water, shade, or breaks.
