Store precut plastic sheeting in your identified shelter-in-place room
Assemble and store food, water, and a battery-operated radio in the room
Practice sealing the room
Establish shelter-in-place procedures wherever you spend significant amounts of time at home, at work, at school
As a rule of thumb, 10 square feet of floor space per person will provide sufficient air to prevent carbon dioxide buildup for up to 5 hours, assuming a normal breathing rate while resting.
