What should we do if we are instructed to “shelter-in-place”?
Sheltering-in-place simply refers to taking refuge in a building, in the event there is an airborne hazard, rather than evacuating from an area. Depending on the situation, it may be safer to quickly shelter-in-place rather than try to drive to a safe area. It might be sheltering at home, at work or in some other other building and if you understand a few principles, it should be easy.
The purpose is to get out of the outside-air and inside a building that is not contaminated. You want to keep the inside-air in, and the outside-air out, until the bad outside-air blows away.
- Close all windows and doors, exterior and interior. Open interior doors as little as possible.
- Turn off all fans, heaters and air conditioners so that they don’t continue to blow outside-air into your house.
- Close the fireplace damper so that outside-air can’t blow down the chimney and inside the building.
- Take water, food and disaster supplies, including a radio, into the most airtight room, preferably one without windows, but with a phone. Bring your pets in with you, along with additional water and food for them.
- Use duct tape or other strong tape to seal all cracks around the door, vents, etc., into the room to help keep out any outside-air.
- Listen on your radio or television for further instructions.
