The arriving firefighters discovered several fires had broken out in five remote locations, filling many different areas of the building with smoke.

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.
