Keeping Outdoor Workers Safe When Temperatures Rise

Every Worker Deserves a Safe, Cool Place to Work — Even in the Heat

Each year, thousands of outdoor workers across the U.S. suffer from heat-related illnesses. Many of these cases are serious—and some are fatal. But here's the good news: every single one is preventable.

Our OSHA Heat Illness Prevention course is dedicated to helping employers, supervisors, and workers recognize and respond to the dangers of working in hot environments. Whether you're on a construction site, in the fields, or doing road work under the blazing sun—this course is here to protect you.

The Risk is Real

Working in hot conditions—especially with high humidity, direct sun exposure, or heavy physical labor—puts strain on the body. Without proper precautions, this can lead to:

  • Heat Cramps
  • Heat Exhaustion
  • Heat Stroke (a life-threatening emergency)

Heat illness can develop quickly and without warning. That's why prevention, awareness, and quick action are critical.

Who Should Pay Attention?

If your job involves outdoor labor or exposure to high heat, you're at risk. That includes workers in:

  • Construction
  • Agriculture and farm work
  • Landscaping and grounds maintenance
  • Oil and gas operations
  • Utility and road repair
  • Roofing, paving, and demolition
  • Waste collection and recycling
  • Delivery and transportation services

WATER. REST. SHADE.

The Core of OSHA Heat Safety Message
  1. Water: Drink cool water every 15–20 minutes—even if you're not thirsty.
  2. Rest: Take regular breaks, especially during peak heat hours (usually 12–4 PM).
  3. Shade: Use shaded or air-conditioned areas for recovery during breaks.

These three steps are simple—but they save lives.
