Fire protection requirements for pipe shafts and cable trays

Fire protection generally demands a defined fire resistance rating for the shaft and tested fire stop (sealing) for service penetrations. Scope: Firestopping for busway, cable trays, cables, and trunking passing through walls in enclosed electrical installations. The Promat construction are partly system protected. All drawings and illu trations remain. Effective protection of cable systems around the world: our tried-and-tested FLAMMOTECT-A and DG-CR 0. 7 products are successfully used to protect cables in high-rise buildings, industrial buildings, and offshore facilities as well as in sensitive areas, such as hospitals, airports, production. Fire stops and collars provide fire-rated separations between units. The overriding aim is to prevent the spread of smoke and fire in the event of a fire and not to reduce the fire resistance classes of adjacent.
