Persons with respiratory problems should make preparations to stay
indoors until the storm passes. Be ready for a sudden drop in
visibility to near zero. If you encounter blowing dust or blowing
sand on the roadway or see it approaching, pull off the road as far
as possible and put your vehicle in park. Turn the lights all the way
off and keep foot off the brake pedal. Remember, `Pull Aside, Stay
Alive`.

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

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

should be moved to a cool and shaded location. Heat stroke is an
emergency! Call 9 1 1.
