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

• Stay hydrated: Remember to drink plenty of fluids.
• Seek cool shelter: Opt for an air-conditioned room to stay comfortable.
• Look out for others: Stay out of the sun, and check up on relatives and neighbors.
• Prioritize child and pet safety: Be vigilant about never leaving young children and pets in vehicles without supervision, especially during periods of intense heat, as car interiors can quickly become extremely hot.
• Take extra precautions outdoors: If you work or spend time outside, be sure to take additional safety measures.
• Consider the timing: When possible reschedule strenuous activities to early morning or evening.
• Familiarize yourself with warning signs: Know the symptoms of heat exhaustion and heat stroke.
• Dress comfortably: Wear lightweight and loose-fitting clothing.

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.
