Drink plenty of fluids, stay in an air-conditioned room, stay out of
the sun, and check up on relatives and neighbors. Young children and
pets should never be left unattended in vehicles under any
circumstances.
When possible reschedule outdoor strenuous activities to early
morning or evening. Know the signs and symptoms of heat exhaustion
and heat stroke. Wear lightweight and loose fitting clothing when
possible. 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.
