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! Call 9 1 1. If you do not have air conditioning in your home or lack shelter, you can call 211 or visit your county or state health department website for assistance locating appropriate shelter from the heat.
