If your workers are exposed to extreme heat this summer, it's your responsibility to be prepared. Be sure to make a plan early.

Dangers of a Heat Advisory

It's a tough decision: You're under a deadline and on a tight schedule when a heat advisory is issued. How do you react? The wrong decision can have disastrous consequences.

A heat advisory is issued by the National Weather Service and occurs when the heat index reaches 105°F. The advisory is sent out when the event is occurring, imminent, or has a very high probability of occurring.

How to Prepare for a Heat Advisory:
Are you ready for a heat advisory? This is how you prepare:

  • Maintain easy access to update weather data and notifications.
  • Secure plenty of cool water in an area that is easily accessible for workers.
  • Make a plan for air conditioned or shady areas to be available for breaks.
  • Educate workers about preventing and watching for heat-related illness before extreme temperatures strike.

What to Do During the Advisory:
When a heat advisory is issued, here is how you can help protect your workers:

  • Provide workers with water, rest, and shade.
  • Allow frequent breaks.
  • Modify work schedules as necessary.
  • Monitor workers for signs of illness.
  • Provide brimmed or vented helmets with neck and ear accessories.

If your workers are exposed to extreme heat this summer, it's your responsibility to be prepared. Be sure to make a plan early. Your hot weather plan should include personal protective equipment (PPE) that helps combat high temperatures, such as cooling vests, air cooling systems, or evaporative cooling products. See the chart below for more details.
