Fire Doors 101

摘要

Fire doors play a vital role in access control and protecting people and property from more than just the outdoor elements. These passive fire protection systems are designed to protect an opening with a fire-rated barrier. Fire doors are typically used to protect openings in exits, such as fire-rated stair enclosures, fire-rated exit corridors, and horizontal exits. They're also installed in fire barrier openings that are designed to protect your building and its occupants from specific hazards, as well as compartmentalize your building into specific fire areas, says Chris Jelenewicz, engineering program manager with the Society of Fire Protection Engineers.
