• Stay in an air-conditioned room.

• Check on others: Stay out of the sun, and make sure to check up on relatives and neighbors.

• Ensure child and pet safety: Do not leave young children and pets unattended in vehicles when car interiors can reach lethal temperatures in a matter of minutes.

• Take extra precautions outdoors: If you work or spend time outside, be sure to take additional safety measures.

• Optimal Timing: When possible, reschedule strenuous activities to early morning or evening.

• Recognize warning signs: Familiarize yourself with symptoms of heat exhaustion and heat stroke.

• Dress for comfort: Wear lightweight and loose-fitting clothing to stay cool.

To reduce risk during outdoor work, the Occupational Safety and Health Administration (OSHA) recommends scheduling frequent rest breaks in shaded or air-conditioned environments. Anyone overcome by heat should be moved to a cool and shaded location. In an emergency, call 911.
