Through penetration firestop

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. Through-Penetration Firestop System An assemblage consisting of a fire-resistance-rated floor, floor-ceiling or wall assembly, one or more penetrating items passing through the breaches in both sides of the assembly and the materials or devices, or both, installed to resist the spread of fire through the assembly for a prescribed period of time.

Penetration (firestop)

Forty years ago, when I started practicing engineering, through penetration firestops were very simple. Once the opening through the fire barrier was made, and the pipe or other item was installed, the annular space was "stuffed" with a non-combustible material such as mineral wool, fiberglass, or heaven forbid, asbestos this was before asbestos was known to be a carcinogen. In , a fire at the Browns Ferry Nuclear Plant demonstrated that it was not only important to seal penetrations to limit the spread of fire, but also to limit the spread of smoke. Previously used materials were found to be inadequate for this purpose. As a result of the fire, Dow Corning Corp.
