Instructions

Know the signs and symptoms of heat exhaustion and heat stroke. Review heat safety and preparedness information at weather.gov/safety/heat. To reduce risk during outdoor work, the Occupational Safety and Health Administration recommends scheduling frequent rest breaks in shaded or air conditioned environments. Drink plenty of fluids, stay out of the sun, and stay in an air-conditioned room. Power outages are possible during periods of extended heat as the extra demand for electricity can tax the power grid. Be prepared for a possible power outage.
