NWS Heat Wave Safety Tips: Stay safe with these recommendations
- Consume plenty of fluids to stay hydrated.
- Find cool shelter: Stay in an air-conditioned room.
- Check on others: Stay out of the sun, and make sure to 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.
- Be cautious outdoors: Take extra precautions if you work or spend time outside.
- Time your activities wisely: If possible, reschedule strenuous activities to early morning or evening when the heat is less intense.
- Recognize warning signs: Know the signs and symptoms of heat exhaustion and heat stroke.
- Dress for comfort: Wear lightweight and loose-fitting clothing to stay cool.
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.
