Every different type and size of pipe and cable penetrating through various walls and floors must have a UL tested and listed system firestopping it. For each of these applications a UL system must be installed to restore the rating of that wall or floor/ceiling and thus prevent the spread of fire, smoke and/or noxious gases. There also may be linear openings at the intersections or corners of construction joints such as can be found at fire-rated wall and floor/ceiling joints where fire could spread from room to room. If not properly “firestopped” a fire could travel through the annular space, spreading from room to room. Fire-rated construction may have openings created by items such as pipes and cables that pass through fire-rated walls or floors – but by penetrating it the fire rating of the entire wall or floor is reduced to zero. Red: materials or devices that seal the opening and restore the fire rating of the constructionĪ UL system is like a “recipe” that includes instructions and drawings on how to install a proper firestop system.
