Take extra precautions when outside by staying hydrated, wearing
lightweight and loose fitting clothing, and limiting strenuous
activities to the early morning or evening. Check up on relatives and
neighbors. Never leave young children or pets in an enclosed vehicle,
even for a short time, as temperatures can quickly rise to
life-threatening levels.

Know the signs and symptoms of heat exhaustion and heat stroke. To
reduce risk when outdoors, 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 ASAP if you or someone you know is exhibiting signs of heat
stroke.
