When notified, you should:
- Seek immediate shelter inside a building (preferably in a room with no windows).
- Additionally, if you are “sheltering” due to a hazardous materials (HAZMAT) accidental release of toxic chemicals, the air quality may be threatened and sheltering in-place keeps you inside an area offering more protection.
- Seek inside shelter if outside.
- Seal off openings to your room if possible (HAZMAT event).
- Remain in place until you are told that it is safe to leave.
