Tips from the NWS for staying safe during a heat wave

• Stay hydrated: Make sure to drink plenty of fluids.
• Seek shelter: Stay indoors in an air-conditioned room to keep cool.
• Avoid direct sun exposure: Protect yourself and check on vulnerable 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.
• Select the ideal time: If possible, move strenuous activities to early morning or evening for more favorable conditions.
• Recognize warning signs: Know the signs and symptoms of heat exhaustion and heat stroke.
• Stay cool with clothing: Select lightweight and loose-fitting outfits for enhanced comfort.

To ensure safety during outdoor work, adhere to the Occupational Safety and Health Administration (OSHA)'s recommendations by incorporating regular rest breaks in shaded or air-conditioned environments. If someone is affected by heat, immediately transfer them to a cool and shaded area. In an emergency, call 911.
