Unreferenced date May 2010 Firestop mortars are mortar masonry mortar s most typically used to firestop large openings in walls and floors required to have a fire resistance rating . They are passive fire protection items. Firestop mortars most often exhibit densities near 1 kg L. This makes the product easy enough to handle, yet heavy enough to absorb a lot of heat from penetrant s, to keep the unexposed side of the assembly cool. Firestop mortars differ in formula and properties from most other cementitious substances and cannot be substituted with generic mortars without violating the listing and approval use and compliance .

A penetration , in firestop ping, is an opening , such as one created by the use of a cast in place Sleeve construction sleeve , in a wall or floor assembly required to have a fire resistance rating , for the purpose of accommodating the passage of a mechanical, electrical or structural penetrant . The penetration may or may not contain a firestop system. A penetration is not a penetrant . A penetration may or may not include a penetrant. Old terminology The nuclear industry in particular used to refer to firestops as penetration seals or penseals . These terms are superseded by the term firestop . Whereas penetration seals or penseals only dealt with openings made to accommodate penetrant s, firestops now also include Joint building . Why the term Penetration firestop ? It is useful to have clarity in construction communications, to differentiate between the opening , whether sealed or not, and the penetrant s, which are optional components of a penetration, as sometimes openings penetrations of the fire barrier are created for future use, especially in electrical service rooms. A firestop, after all, tends to be easier to remove than concrete , which requires coredrilling equipment, cooling water, etc. A firestopped penetration may also be referred to as a firestop, as a firestop, by definition, is a system . Therefore, the terms firestop and penetration can at times be deemed to be interchangeable.

Summary Firestop Mortar seal at a pulp and paper mill in British Columbia , Canada . Firestop mortars of sufficient strength and depth, at densities not far above 1kg L can absorb heat from penetrant s and also withstand the heat induced expansion and motion of ferrous cable trays that are exposed to fire. They tend to be noncombustible and easy to install. Notice that this firestop bears an identification tag, with clear bounding references, such as the applicable Underwriters Laboratories certification listing number, to enable intelligent maintenance.

Summary Passive Fire Protection Example 90 minute fire resistance rated barrier, including fire door on the left, a cable penetration firestop sealed with a firestop mortar http www.geocities.com astximw whymort.html and cables coated with an intumescent fire retardant, which reduces the flame spread along cable jacketing and neutralises hydrochloric acid evolution that may result from fire exposure of the cable jacketing. Another consideration Steel expands during fires, which results first in pushing of the cable tray against the firestop mortar http www.geocities.com astximw whymort.html . Subsequent to the pushing, once steel has reached its critical temperature above 500 C, the cable tray may collapse and the pull on the firestop . Public testing in Germany has verified that properly installed firestop mortar seals are capable of resisting both the pushing and pulling motion that is inevitable as a result of the fire exposure upon Steel cable trays.

Image Standpipe penetration.jpg thumb left Riser clamp in use on a Standpipe firefighting standpipe Penetration firestop through penetration firestop inside a fire hose cabinet that is under construction. A Riser clamp is a device used by mechanical building trades to support vertical runs of piping at each floor level. The devices are placed around the pipe and integral fasteners are then tightened to clamp them onto the pipe. The friction between the pipe and riser transfers the weight of the pipe through the riser to the building structure. Risers are generally located at floor penetrations, particularly for continuous floor slabs such as concrete. They may also be located at some other interval as dictated by local building codes or at intermediate intervals to support plumbing which has been altered or repaired. Heavier piping types such as cast iron require more frequent support. Ordinarily, riser clamps are made of carbon steel and individually sized to fit certain pipe sizes. The term riser is typically used to refer to vertical runs of pipes, electrical conduit and tubes. Category Piping Category Plumbing ... more details
