Some chemical emergencies may not be suitable for a Shelter-In-Place (SIP) protective measure. It may be safer for you to leave the area of danger and evacuate.  

Evacuation may be an appropriate protective measure, but you should not attempt an evacuation during a chemical emergency unless specifically ordered by first responders. Leaving your home or business may expose you to more chemical vapors.
