Take extra precautions if you work or spend time outside. When

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 911.

An excessive heat watch means that a prolonged period of
dangerously hot and humid weather is anticipated. Afternoon heat
indices in excess of 110 degrees with nighttime low temperatures
of 78 degrees or warmer are forecast for at least two consecutive
days. The combination of hot temperatures and high humidity will
combine to create a dangerous situation in which heat illnesses
are possible.
