firecase

A firecase is a type of protective enclosure designed to contain a fire and prevent its spread, typically within a building or a specific area. These enclosures are constructed from fire-resistant materials that have a high melting point and can withstand prolonged exposure to high temperatures without compromising their structural integrity. The primary purpose of a firecase is to provide a barrier that limits the movement of flames, smoke, and hot gases from one compartment to another, thereby giving occupants more time to evacuate and allowing firefighters to control the blaze.

Firecases can be found in various forms, including fire doors, fire-rated walls, and fire-rated shafts for elevators or utilities. The effectiveness of a firecase is determined by its fire-resistance rating, which is usually expressed in hours. This rating indicates how long the enclosure can withstand a standardized fire test before failing. Building codes often mandate the use of firecases in specific locations and applications to enhance passive fire protection strategies. They play a crucial role in subdividing buildings into smaller fire compartments, slowing down the progression of a fire and contributing to overall fire safety. Regular inspection and maintenance are essential to ensure that firecases remain effective and fully functional.
