- Quickly try to define the impacted area or where the chemical is coming from, if possible.
- Take immediate action to get away.
- If the chemical is inside a building where you are, get out of the building without passing through the contaminated area.
- If you can't get out of the building or find clean air without passing through the area where you see signs of a chemical attack, it may be better to move as far away as possible and shelter-in-place.
If you are instructed to remain in your home or office building, you should:
- Close doors and windows and turn off all ventilation, including furnaces, air conditioners, vents, and fans.
- Seek shelter in an internal room and take your emergency go kit.
- Seal the room with duct tape and plastic sheeting.
- Listen to your radio for instructions from authorities.
If you are caught in or near a contaminated area, you should:
- Move away immediately in a direction upwind of the source.
- Find shelter as quickly as possible.
- Determine the fastest way to find clean air. Consider if you can get out of the area or if you should go inside the closest building and shelter-in-place.
