Tips from the NWS for staying safe during a heat wave

• Stay hydrated: Keep yourself well-hydrated by drinking plenty of fluids.
• Find cool shelter: Stay in an air-conditioned room.
• Avoid direct sun exposure: Protect yourself and check on vulnerable relatives and neighbors.
• Ensure child and pet safety: Take every precaution to never leave young children and pets alone in vehicles, especially in extreme heat when car interiors can quickly become hazardous.
• Take extra precautions outdoors: If you work or spend time outside, be sure to take additional safety measures.
• Time your activities wisely: If possible, reschedule strenuous activities to early morning or evening when the heat is less intense.
• Know the red flags: Understand the signs and symptoms of heat exhaustion and heat stroke.
• Dress appropriately: Wear lightweight, loose-fitting clothing to stay comfortable.

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.
