Information:
A Heat Advisory means that a period of hot temperatures is
expected. The combination of hot temperatures and high humidity
will create a situation in which heat illnesses are possible.
Drink plenty of fluids, stay in an air-conditioned room, stay out
of the sun, and check up on relatives and neighbors.
Take extra precautions, if you work or spend time outside. When
possible, reschedule strenuous activities to early morning or late
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.
