Fire protection

Through-penetrations of fire-resistance-rated walls by conduits must be protected with a firestop system (MLAR 2005).

Firestopping includes all actions and measures aimed at preventing the propagation of fire and smoke, allowing the rescue of humans and animals, and effectively fighting the fire.

The BSM-E fire protection sleeve type AWM II contains an intumescent material, expandable graphite, which foams with great pressure in case of fire. This intumescent paint permanently seals fitting openings against fire and smoke.
