There may be a time when an emergency takes place in our community due to a hazardous materials release including chemical, biological and/or radiological contaminants. In this example, the outside air quality may be affected to the point that it isn't safe to be outside or to evacuate. In a case like this it is usually safer to shelter-in-place until wind disperses and moves the material.
“Shelter in place” means selecting an interior room(s) or one without, or with few, windows. The below items should be available to you in a toolkit located in or near your shelter in place location:
Plastic for windows
Towel for under doors
Commercially processed bottled water and food that won't spoil
