The Fundamentals of Passive Fire ProtectionInvestigating the fundamentals of passive fire protection.
Introduction Passive fire protection (PFP) is a range of measures designed to prevent, contain or slow the spread of fire from the area of origin to other areas in the building PFP compartmentalises a building to prevent and slow the spread of fire, minimise damage and give occupants more time to evacuate PFP is one of the three key components of structural fire protection in buildings The other two components are Active Fire Protection Education
The Goals Of Passive Fire Protection Protection of life Protection of property Continuity of business operations
Passive Fire ProtectionMethods There are four main passive fire protection methods available; Cavity Barriers Intumescent Coatings Boarding Systems Fire Resistant Glass
1. Cavity Barriers Cavity barriers are designed to prevent the spread of smoke and fire through walls, floors and cavities in building This is done by installing a range of passive fire protection products that offer resistance to the movement of smoke and fire inside spaces
2. Intumescent Coatings Intumescent coatings provide an appearance that is comparable to paint However, in a fire situation the temperature increase causes a chemical reaction causing the intumescent coating to expand Intumescent coatings act to protect steelwork by insulating the steel, preventing the temperature of the steel reaching such a heat which would cause structural failure
3. Boarding Systems PFP via boarding systems involve encasing structural steelwork in rigid and semi-rigid boards to protect the structural integrity of steelwork in the event of a fire.
4. Fire Resistant Glass Fire resistant glass uses intumescent technology that on experiencing a temperature increase becomes viscous and forms a dense, heat insulating material that halts the spread of fire and chance of window blow outs.
