An Extreme Heat Warning means that a period of very hot temperatures,

even by local standards, will occur. Actions should be taken to

lessen the impact of the extreme heat.



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 lightweight 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.
