Tips from the NWS for staying safe during a heat wave

• Stay hydrated: Remember to drink plenty of fluids.
• Stay in an air-conditioned room.
• Avoid direct sun exposure: Protect yourself and check on vulnerable relatives and neighbors.
• Child and pet safety: Never leave young children and pets unattended in hot vehicles – 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: Know the signs and symptoms of heat exhaustion and heat stroke.
• Dress comfortably: Wear lightweight and loose-fitting clothing.

To minimize risks during outdoor work, the Occupational Safety and Health Administration (OSHA) advises incorporating frequent rest breaks in shaded or air-conditioned areas. If someone experiences heat-related symptoms, promptly relocate them to a cool and shaded spot. In case of an emergency, dial 911.
