The main purpose of fire and smoke curtains is to prevent or slow down the ingress of fire and smoke. The curtains should enclose or canalise smoke and/or fire to prevent it from spreading. Most lift doors will not be fire rated and therefore they would need to be protected to maintain the compartmentation of the lift shaft.
Removing compartment walls and replacing them with fire curtains could provide more work for Fire Contractors.
It is a common desire to create atria and other open spaces in large buildings by removing multiple small areas, however this has a negative impact on fire compartmentation. Fire curtains are an ideal solution when compartment walls are removed - but is installing fire curtains alone enough to maintain safe conditions in a fire?
Mike Washbourne, Easivent’s in-house fire curtain expert explains how Fire Contractors determine the best choice of fire curtain.
The main purpose of fire and smoke curtains is to prevent or slow down the ingress of fire and smoke into other areas of a building and are often used in place of heavy and intrusive fire doors. The curtains should enclose or canalise smoke and/or fire to prevent it from spreading. In combination with smoke and heat exhaust systems, fire and smoke curtains help keep emergency and escape routes clear.
Smoke and fire curtains are typically automated, and drop down when a fire alarm panel or smoke/heat detector is activated. To provide protection, they are fitted to the exact measurements of a specific area. All non-domestic buildings are required to operate in a fire safe manner, using fire curtains where appropriate. Automatic fire curtains are increasingly being used in place of fire doors or shutters to unobtrusively maintain fire separation in buildings.
