extremely hot temperatures will occur. 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.

The occupational safety and health administration recommends
these additional steps to reduce risk during outdoor work...
schedule 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.
