Passive firestop systems help prevent the spread of fire, smoke, and toxic gas through openings created by penetrations and gaps between walls or floors/ceilings in fire-rated construction. The firestopping of openings re-establishes the integrity and fire rating of a wall, floor, or assembly and aids in the protection of escape routes. This course identifies the main through-penetration firestop technologies, evaluates the materials and products that are used to firestop through penetrations in commercial applications, and discusses industry fire testing standards.
Upon completion of this course, the Learner should be able to:
- Recognize different construction types, penetrating items, and the need for through-penetration firestopping to help prevent the spread of fire, smoke, and toxic gases.
- Apply Underwriters Laboratories (UL) system nomenclature to identify through-penetration firestop systems.
- Discuss relevant industry standards and determine the testing requirements for a range of through penetrations.
- Discuss the attributes of firestop materials and assemblies and their role in saving lives and property, and identify system solutions for through-penetration applications.
- Compare today’s firestop products and technologies that are incorporated in through-penetration commercial applications.
