FIRE PROTECTION
Primary objectives:
Save lives by allowing evacuation of people
Allow safe access for fire fighters
Protect the building from structural failure

FIRE PROTECTION
Structural steel can be fireprotected by a variety of
methods including:
1.Concrete encasement
2. Fire resistant boards,
3. Cementitious,4. Sprayed inorganic materials
5. Intumescent coatings.

FIRE PROTECTION
These methods are commonly referred to as passive fire
protection.
Their function is to insulate the steel in a fire situation and
increase the time before the steel loses its design margin of
safety. This usually occurs at a steel temperature of around400C - 600C.
All commonly used building materials may lose some strength
when exposed to fire. Concrete may spall to exposereinforcement, wood depletes by charring and steel starts to
lose its load bearing capacity.

FIRE PROTECTION
Each country has its own building regulations and
design codes, which broadly state that the load bearingelements of a building shall be capable of resisting fire
for the advised period without loss of stability in the
event of fire.
The period of fire protection is normally 30 minutes, 60
minutes, 90 minutes or 120 minutes. This duration is
dependent on the building use, type, size and overall
height.
