Beat the Heat and Stay Safe on the Job

August 7th, 2025

Outdoor workers face serious risks in hot, humid weather. Know how to prevent heat stress when temperatures rise.

Heat exposure can affect worker health in a number of ways:

Heat cramps: Muscle spasms.
Dehydration: Dizziness, confusion, decreased urination.
Heat exhaustion: Fatigue, nausea, pale or cool skin, heavy sweating; needs prompt attention.
Heat stroke: High body temp, headache, rapid pulse, nausea, hot or dry skin, confusion or unconsciousness. Heat stroke can be fatal; call 9-1-1 immediately.

Prevention is key

Drink water every 15 minutes. Consider electrolytes.
Eat light and avoid hot meals.
Wear a hat and sunglasses. Apply sunscreen regularly.
Wear lightweight, light-colored clothing. While necessary for safety, be aware that personal protective gear can increase body heat.
Acclimatize and gradually increase heat exposure. Allow new or returning employees time to adjust.
Take frequent breaks in a shady or cool location. Schedule heavy work for cooler times of the day.
Know the signs of heat-related illness and get medical help promptly if needed.
