An excessive heat warning means that a prolonged period of
dangerously hot temperatures will occur. The hot temperatures
will 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.

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 911.
