FAQ's – Fire Protection

  • Ablative

    Literally means “carried away,” which refers to the fact that ablative coatings are sacrificial—they absorb the energy of a fire to protect what is underneath, buying valuable time. They work by consuming heat energy from a fire, releasing it in the form of gases as they char to form an insulation.

  • Building Warrant of Fitness (BWOF)

    Being the building owner brings responsibility for its continued maintenance and required certification. As the owner, you are required to renew a building’s warrant of fitness (BWOF) every 12 months, signing, issuing and publicly displaying to prove the building’s life safety specified systems, including all passive fire protection systems, have been maintained and inspected by IQPs or other certified inspectors.

  • Firestop

    A firestop is a fire protection system made of various components used to seal openings and joints in fire-resistance rated wall or floor assemblies. For penetrating cables, these can also be called as Multi Cable Transits (MCTs). Firestops are designed to restore the fire-resistance of wall or floor assemblies, impeding the spread of fire by filling the openings with fire-resistant materials.

  • Fire Resistance Rating (FRR)

    Fire Resistance Rating (FRR) is the term that classifies fire resistance of primary and secondary building elements, as determined in a standard test for fire resistance. The FRR is made up of three numbers and functions, measured in time (in minutes) for which each of the criteria Stability, Integrity, and Insulation are satisfied. Read as, for example, - / 90 / 90.

  • Fire Resistance Rated Walls

    Firewall, fire barrier, fire shield; call it what you want – it’ll save lives.

    Firewalls are essentially fire resistant barriers designed to prevent the spread of a fire from one area to another for a particular amount of time.

  • Intumescent

    An intumescent is a substance that swells as a result of heat exposure, thus increasing in volume and decreasing in density. Intumescents are typically used in passive fire protection and require listing, approval and compliance in their installed configurations in order to comply with the national building codes and laws.

  • Integrity (E)

    The Integrity fire rating (E) is the ability of an element’s fire separation capability to resist and limit penetration or passage of flames and gasses through its joints and to prevent the occurrence of flames on the unexposed side, during a fire.

  • Insulation (I)

    The insulation fire rating (I) is the time defined, by a separating element of building construction, to restrict the rise of temperature on the non-exposed side during a fire.

  • Passive Fire Protection (PFP)

    Passive Fire Protection (PFP) is an integral component of the three components of structural fire protection and fire safety in a building. PFP attempts to contain fires or slow the spread, through use of fire-resistant walls, floors, and doors (amongst other examples). PFP systems must comply with the associated listing and approval use and compliance in order to provide the effectiveness expected by building codes.

  • Stability (R)

    The Stability fire rating is based upon the time a fire protection element can withstand a standard fire test and hold its loadbearing limit while allowing a level of defined load capacity. Essentially, the higher the R rating, the more ability the element has to resist a fire when exposed and when under load during a longer time period.

  • What is a fire rated resistance door?

    The sole purpose of a fire door, other than to be like any other door and open and shut, lock etc., is to protect lives, shield areas of a building and provide protection from fire as well as safe passage for occupants.

    Fire doors are measured, excluding the Stability FRR criterion. For example, -/30/30 means: Stability no requirement/ Integrity 30 minutes/ Insulation 30 minutes.
