What Are The Areas Of Passive Fire Protection?


Many might not know about passive fire protection and just how effective it can be when it comes to fire hazards. To begin from the top, Passive Fire Protection (PFP) is a term which encompasses a huge spectrum of practices and products. It refers to the materials which have been built into the various structures that surround us. This is done with the intention to prevent or slow down fire from spreading. As such, the goal of PFP involves maximizing the total time available when it comes to evaluating a property or preventing a fire from beginning in the very first place. Here’s more information about Passive Fire Protection:

What are the areas of passive fire protection?

There are four major areas:

  • Structural fire protection: This is done to ensure that the major structural components like the joint systems or the structural steel remain protected from fire effects. This is done by using fireproofing materials which include endothermic stuff like cementitious products and gypsum-based plasters, mineral wool wraps and insulation, thin-film intumescents, fireproofing cladding or building the whole structure from concrete products.


  • Compartments: This involves making use of firewalls, barriers, fire partition and smoke barriers to slow down the spread of fire. When it comes to fire barriers you can make use of fire-rated floors, walls, ceilings (made out of combination wood, concrete, gypsum and such). The walls extend right from fire rated floors to that of fire rated ceilings put above. But that’s not all as they do continue into various concealed spaces as well so that there is all-encompassing protection.


  • Opening protection: This is a method which says that fire windows and doors should be put right in an opening of a fire barrier so as to keep its fire resistance. This is because the hardware, doors and the frames all work together to form a very effective fire and smoke barrier. The fire rated glass or glazing along with framing should be fully tested when its assembly is completed. Additionally, the smoke and fire dampeners are very often thought to be “opening protection”. They also complete the fire barrier where the air ducts are able to penetrate the fire or smoke resistance structures.


  • Fire-stopping materials: These are the things which are made use of to prevent the fire from spreading through the penetrations present in a fire barrier. But if the penetration isn’t properly sealed off and protected using an appropriate fire-stop system, then the fire barrier will be less effective. As a result, the fire will spread behind the origin compartment.

Other passive fire-protection areas to pay attention to

While these are the main four areas related to PFP, but there are other areas which are worth mentioning and they involve:

  • Cable coating: It is the use of fire retardants to cable and wire.
  • Joint systems: These include changes made in the direction between the fire separating elements as well as in the spaces which surround those elements.
  • Perimeter fire barriers: These involve dealing with the whole perimeter of a floor as well as with the exterior part of the curtain-wall.

While these are effective methods but you should put in fire alarms, sprinkler systems and such with these passive fire-protection methods for more rounded protection.
