Thru fire penetrations

What are membrane penetration firestop systems and how has the penetration firestop standard evolved to evaluate them? The changes include a new section for definitions relating to the various types of membrane-penetrations, a description of the test setup for membrane-penetrations, and the conditions of acceptance for membrane-penetrations. For example, when a firestop system protecting a plumbing pipe penetrates the gypsum membrane on one side of a fire-resistance-rated gypsum wall, this revised standard would be used to evaluate that firestop system. Penetration Firestop System A through-penetration firestop or a membrane-penetration firestop. Membrane-Penetration Firestop System An assemblage consisting of a fire-resistance-rated floor-ceiling, roof-ceiling or wall assembly, one or more penetrating items installed into or passing through the breach in one side of the assembly and the materials or devices, or both, installed to resist the spread of fire into the assembly for a prescribed period of time.

Membrane penetration firestop systems - International Fire Protection

Penetrations in fire-rated construction can allow spread of fire and smoke from one firecell to another if they are not correctly tested, specified or installed. It is always recommended to resolve and specify fire rated service penetrations in the design office rather than on-site. For proprietary systems contact the relevant penetration seal supplier. Through penetrations such as metal or plastic pipes, cable trays, ducts, etc.

Penetrations Through Rated Wall and Floor Assemblies

Penetration firestopping systems and fire resistive joint systems are a passive means of fire protection. There is no movement or activation required. These passive systems are mainly used to compartmentalize a fire and keep it from spreading for a period of time long enough that occupants can evacuate the building and so firefighters can perform initial lifesaving tasks.
