* Impacts... increased risk for heat exhaustion or heat stroke
for people spending time outside or living without air
conditioning. Children and the elderly are most susceptible.
Also, parked vehicles will become dangerously hot within
minutes.

Precautionary/preparedness actions...

An excessive heat warning means that a prolonged period of
dangerously hot temperatures and high humidity will occur. This
combination will lead to a dangerous situation in which heat
illnesses are likely. Drink plenty of fluids, stay in an air-
conditioned room, stay out of the sun, and check on relatives and
neighbors, especially the elderly.

Take extra precautions if you work or spend time outside. When
possible, reschedule strenuous activities to early morning or
evening. Know the signs and symptoms of heat exhaustion and heat
stroke. Wear light weight and loose fitting clothing when
possible and drink plenty of water.

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.
