Electrical conduits as well as cables and wires running through several fire sections must be secured using fire stops.
Wall or ceiling breakthroughs are called firewalls or fire stops. Fire stops must feature the same fire resistance as the respective wall or ceiling and includes all protective measures preventing propagation of fire and smoke allowing the rescue of humans and animals and effective fire-fighting operations in case of fire.. The term circuit integrity is closely connected with the term fire resistance and means that a component functions in normal use over a long period of time before it is subjected to fire.
BSM-E fire stop for electrical conduits
The BSM-E fire protection sleeve ensures safety in fire protection installation, since it contains intumescent material, expandable graphite, which foams with great pressure in case of fire. This intumescent material permanently seals fitting openings against fire and smoke.
The sleeve can also be retrofitted, and offers secure sealing of fire protection walls and ceilings in the event of a fire in buildings.
