Precautionary/preparedness actions...

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

Young children and pets should never be left unattended in a
vehicle under any circumstance. This is especially true during
hot weather when a car's interior can reach lethal temperatures
in a matter of minutes.

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.

An excessive heat warning means that a prolonged period of
dangerously hot temperatures will occur. The combination of hot
temperatures and high humidity will combine to create 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 up on relatives and neighbors.
