Concrete masonry is widely specified for fire walls and fire barriers because it is noncombustible, durable and economical. Firestopping must be installed in accordance with code requirements to maintain fire and life safety. Choosing an appropriate firestopping system is a key component to a successful installation.
Openings for electrical and HVAC installations in smoke and fire-rated constructions must be sealed to resist the passage of heat, fire and smoke. The F-rating is expressed in hours and the number indicates the specific length of time that a barrier can withstand fire before being consumed or before permitting the passage of flame through the opening. The T-rating is expressed in hours and the number indicates the length of time that the temperature on the non-fire side of the penetration does not exceed o F o C above the ambient temperature.
Log in. Sign Up. The provisions of this section shall govern the materials and methods of construction used to protect through penetrations and membrane penetrations of horizontal assemblies and fire-resistance-rated wall assemblies.
Through penetration firestop systems are intended to restore the hourly rating of fire-resistive assemblies that have been breached by the penetration of electrical, plumbing or mechanical items. Fire resistant compartments or buildings will typically incorporate transitions between floors and walls, adjacent walls and other fire resistant barrier intersections. Often, these joints are designed to cater for building movement, and to avoid the transfer of loads during heating and cooling of the building, into the elements themselves. Fire sealing systems for control joints must allow for movement while providing effective firestopping qualities.
Mike, I'd like to run my grounding electrode conductor in PVC, but I need to go through a fire rated concrete deck from floor to floor. Mike Holt's Answer: Yes. Section states that electrical installations in hollow spaces, vertical shafts, and ventilation or air-handling ducts shall be made so that the possible spread of fire or products of combustion will not be substantially increased.

For approximately 40 years, unprotected or improperly protected penetrations have presented a subject of much concern to the fire-protection community. The arriving firefighters discovered several fires had broken out in five remote locations, filling many different areas of the building with smoke. According to the National Fire Protection Association's report on the fire, unprotected vertical and horizontal penetrations provided one of the major contributing causes of the rapid, erratic spread of smoke and fire.
