Description of the Concept
Shelter-in-place is a protective action that can be requested by the local authorities to the community. Shelter-in-place can be defined as a procedure that basically requires residents to seek shelter, close doors and windows, and seal vents, doors, and windows. This provides a physical protective barrier from the airborne chemical and contained non-contaminated air. Studies have shown that even poorly sealed buildings offer protection from large exposure to gas.
Shelter-in-place instructions are given in emergencies when risk to chemical exposure will adversely affect health or life due to the known or unknown properties of the chemical, volume released, and rapid movement of chemical through the air. Chemical emergencies requiring shelter-in-place usually only occur over a short length of time such as 3-4 hours.
When asked to shelter-in-place, proceed to home or nearest building, shut down ventilation systems, seal doors and windows, and remain indoors until instructed by authorities. Preplan for shelter-in-place by packing supplies into kits and predesignating an above ground room with the fewest doors and windows to remain during the emergency.
