An investigation into the fundamentals of passive fire protection.

1. The Fundamentals of
Passive Fire Protection
Investigating the fundamentals of passive fire protection.

2. 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

3. The Goals Of Passive Fire
Protection
 Protection of life
 Protection of property
 Continuity of business operations

4. Passive Fire Protection
Methods
 There are four main passive fire protection methods
available;
 Cavity Barriers
 Intumescent Coatings
 Boarding Systems
 Fire Resistant Glass

5. 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

6. 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

7. 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.

8. 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.

9. Corecut
 Corecut offer a wide range of passive fire protection services.
Corecut is headquartered in Broxburn in West Lothian and
has strategically placed branches throughout the country. It
is regarded a leader in the field of diamond drilling, concrete
sawing and concrete cutting.
