Fire Safety Upgrading for Fallout Shelters in Buildings

摘要

The report suggests methods, mainly untried, for upgrading on an emergency basis the fire safety of existing fallout shelter buildings. The methods suggested are not substitutes for normal peacetime protection which may be: (1) hard to implement, (2) too costly, or (3) incompatible with flexibility of building operations. The report is based on the following concepts: (1) fire exposures to a shelter building from without must be denied entry to the shelter building, (2) fires in a shelter building must be promptly detected and suppressed or extinguished, and (3) occupants must be provided with an environment which will sustain life. Most of the remedies suggested are passive such as physical barriers to prevent fire entry to the shelter building. Specifically, thermal barriers for window openings, automatic smoke detectors with manual response by fire fighting shelter personnel, and environmental seals for shelter areas are recommended as feasible upgrading remedies.
