During the unlikely event of a chemical emergency or other emergency, the best way to protect you and your family may be to Shelter-in-Place. This simply means to go inside your home or office and follow some basic safety procedures to avoid contact with outside air.
Move everyone indoors.
Close and lock all windows and doors for a tighter seal.
Turn off heating, cooling and ventilation systems.
Everyone should go into 1 room.
Place plastic and duct tape around all windows, doors, vents, and fans.
Place wet, clean towels under the doors and if you smell a chemical odor use a wet towel to cover your nose and mouth.
Do not use the phone unless is is life threatening situation. Emergency personnel will need the phone lines.
Listen to a local radio or television station for further instructions.
When you are notified of the all-clear signal, open doors and windows to ventilate your home or office.
