Drink plenty of fluids, stay in an air-conditioned room, stay out of
the sun, and check up on relatives and neighbors. Young children and
pets should never be left unattended in vehicles under any
circumstances.
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.
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.
For sheltering information and other human services in your area,
dial 2 1 1 during business hours or visit wa211.org anytime.
To stay safe when heat and smoke are present, go to spaces with
indoor cooling and air filtration. To cool spaces with no air
conditioning, pull shades to block daytime heat. Use portable air
cleaners or DIY box fan filters to help cool and clean air. Stay
hydrated and limit activity until heat and smoke improve.
