Protect yourself during a heat wave with these tips from the NWS

• Stay hydrated: Drink plenty of fluids.
• Seek shelter: Stay indoors in an air-conditioned room to keep cool.
• Look out for others: Stay out of the sun, and check up on relatives and neighbors.
• Child and pet welfare: Never forget to safeguard young children and pets by not leaving them unattended in vehicles, especially during scorching weather when car interiors can become life-threateningly hot.
• Be cautious outdoors: Take extra precautions if you work or spend time outside.
• Consider the timing: When possible reschedule strenuous activities to early morning or evening.
• Recognize early indicators: Learn to identify the warning signs of heat exhaustion and heat stroke.
• Stay cool with clothing: Select lightweight and loose-fitting outfits for enhanced comfort.

For a safer outdoor work environment, follow the Occupational Safety and Health Administration (OSHA)'s guidance by scheduling regular rest breaks in shaded or air-conditioned places. If anyone shows signs of heat illness, promptly move them to a cool, shaded area. In an emergency, call 911.
