Fire stopping
New cables, pipework and maintenance activity can disturb compartment lines. Early reporting helps prevent an unrecorded opening from becoming a route for smoke and fire.
Damage is not always a large open hole. Small annular gaps, removed collars, unsupported systems or unsealed additions may all need investigation.
Generic foam, mortar or sealant is not automatically a fire-stopping system. Suitability depends on the substrate, service, opening, supports and required rating.
A useful record links the finished installation to a location and suitable tested detail.
