interiors will reach lethal temperatures in a matter of minutes.

Take extra precautions when outside. Wear lightweight and
loose-fitting clothing. Try to limit strenuous activities to early
morning or evening. Take action when you see symptoms of heat
exhaustion and heat stroke.

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.

Monitor the latest forecasts and warnings for updates.
