OSHA, National Weather Service to mark National Heat Awareness Day

Agencies provide tips for preventing heat-related illness, death

Posted May 29, 2019

OSHA and the National Weather Service are teaming up on May 31 to encourage employers and workers to recognize the warning signs for heat illness and to keep workers safe. Every year, dozens of workers die and thousands more become ill while working in extreme heat or humid conditions. OSHA notes that while 40 percent of heat-related deaths occur in the construction industry, workers in every field are susceptible.

OSHA recommends employers with workers exposed to high temperatures:

  • Provide workers with water, rest, and shade.
  • Allow new or returning workers to gradually increase workloads and take more frequent breaks as they acclimatize, or build a tolerance for working in the heat.
  • Plan for emergencies and train workers on prevention.
  • Monitor workers for signs of illness.

For workers, OSHA and the National Weather Service offer the following tips:

  • Drink plenty of water even if you don’t feel thirsty.
  • Take breaks in the shade as often as possible.
  • Wear a hat and light-colored clothing.
  • Learn the signs of heat illness and what to do in an emergency.
  • Keep an eye on fellow workers.
