FIRE SAFETY FEATURE
What is passive fire protection in the workplace? A
s the name ‘passive fire protection’ suggests, it remains inert during daily life and only
becomes active during an actual fire situation. Passive fire protection is often forgotten about
and is invisible to most people, until you come to need it, that is when it is truly appreciated.
HOW DOES IT WORK? Typically, this passive protection is an integral component of most building structures. It is designed to contain or slow the progress of fires to allow employees to evacuate the building and the fire brigade to arrive. There are several different kinds of passive fire protection that can have a real impact on a building’s natural defences and resilience against the rapid spread of fire. This type of protection can also reduce the
amount of damage that a building encounters after a fire, and therefore assisting in protecting critical structures to stop the building collapsing. As well as protecting the people in a building
when a fire occurs, passive fire protection can also help the emergency services by slowing the spread of flames, gases and smoke.
COMPARTMENTATION The items included in compartmentation are fire barriers, firewalls, partitions and smoke barriers. Fire barriers include fire-rated walls/floors/
ceilings and are used to limit the spread of fire. Fire-rated walls extend from the floors to the ceiling for full protection. Fire doors are also included in
compartmentation and stop the fire and smoke from travelling too much. It minimises damage and helps play a vital role in reducing the spread of fire. As well as stopping the spread of fire, it also stops the spread of smoke through smoke seals.
STRUCTURAL PROTECTION Protection of the structure of a building is accomplished through fireproofing material or building the structure from concrete products. Fireproofing examples include spray on intumescents, endothermic materials, products made from cement, mineral wool wraps and insulation, and fireproof cladding. Having effective protection can guard structural components from the effects of fire.
FIRE STOPPING MATERIALS Intumescent seals are chemically designed to expand when exposed to extremely high temperatures. The seal reacts to fire by expanding and then forming a seal to contain a fire and give people more time to escape. These seals are on most things like fire doors, pipes, fire hoods, socket box inserts/covers and air transfer grills.
Air transfer grills circulate the air in a building
under normal conditions. When there is a fire (the indicator being heat) the intumescent material expands to create a barrier for the hot gases produced in a fire. Other examples include cable coating,
intumescent pipe collars and wrap, and fire hoods/canopies.
PROBLEMS WITH PASSIVE FIRE PROTECTION Because of the nature of passive fire protection - something that is built into a building and remains dormant or inert in normal conditions - people can sometimes forget the importance of it. The main one which most people are familiar
with is fire doors. Some of the common problems with fire doors are: damaged doors; gaps around the door from bad fittings; smoke seals missing due to falling off or damaged in some way; doors being wedged open; and the self-closing system not working correctly Walls and ceiling also have problems:
insufficient installation; non-fire resistant foam used to fill holes in walls; and holes in walls, floors or ceilings allowing a fire to spread. Having the correct and effective passive fire
protection procedures in place can help save lives and prevent harm to others.
