# PRECAUTIONARY/PREPAREDNESS ACTIONS
--------------------
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.
