What’s the safest way to shelter in place during a chemical attack?

Preparing a Safe Shelter

When preparing a shelter, it’s essential to consider the layout and materials used. Ideally, a shelter should be a basement or a room with no windows, such as a bathroom or closet. If these options are not available, use a room with windows, but make sure to cover them with multiple layers of plastic sheets or tarps, securing them with duct tape to prevent gaps. A fan should be used to pull clean air from an exterior source, like a door or window on the opposite side of the building, into the shelter.

Decontamination and Protection

Once you’re inside the shelter, remove any contaminated clothing, including shoes, and wash exposed skin with soap and water. Use a decontamination solution, such as diluted bleach, to clean any equipment or objects that may have come into contact with the chemical. If you have a gas mask or respirator, put it on to prevent inhalation of the chemical. Use a bandana or cloth to cover your face and nose, if a gas mask is not available. If you’re with others, make sure to account for any people with disabilities or young children, who may need special assistance.

Waiting out the Attack

While waiting for the chemical attack to pass, stay in the shelter and avoid any areas that may be contaminated. If you’re in a building with a basement or a room without windows, it’s likely safer to wait there. If you’re in a mobile home or a vehicle, leave immediately and move to a safer location. Monitor local news and follow evacuation instructions from authorities. If symptoms develop, such as difficulty breathing or nausea, seek medical attention as soon as possible.
