If you don't have home air conditioning, continue to seek out cool spaces each day as long as it remains hot, and for a few days after if your home is still hot. Check on vulnerable friends, family members and neighbors. To reduce risk during outdoor work, the Occupational Safety and Health Administration recommends scheduling frequent rest breaks in shaded or air conditioned environments. Anyone overcome by heat should be moved to a cool and shaded location. Heat stroke is an emergency! In cases of heat stroke call 9 1 1.
