FIRE SAFETY PROVISIONS (TO SUPPRESS A FIRE)Before allocating proper fire safety provisions, Fire Safety Objectives shall be well aware of. These will affect design of floor layout, building massing and structural systems. 7
COMPLIANCEThe adequate of fire safety provisions in a building should be demonstrated by complying with the Performance Requirements of various codes. Compliance can be achieved by :(a)Complying with the Deemed-to-comply provisions ( Prescriptive approach ) of various codes, or(b)Formulating an Alternative Solution which complies with the Performance Requirements ( Fire Engineering Approach ) or(c)A combination of (a) and (b)8
Fire protection systemFire safety provisions means the installations, equipment, systems, building elements or methods used in a building to achieve the fire safety objectives. The provisions include active and passive fire safety provisions :Fire protectionsystemActivePassive2
FIRE SAFETY PROVISIONS(a)Passive fire safety provisions,They are mainly structural and building components to contain or slow the spread of fire, eg, fire resisting construction, fire retardants, wall lining with low combustibility, smoke seals, fire rated doors(b)Active fire safety provisions, These are provisions/systems that are characterized by the actions and response of the provisions/system taken against fire in order to alert, suppress and/or extinguish it, eg, sprinkler system, detectors and alarms system & etc
Passive fire protectionPassive Fire Safety Protection – AimBuilding materials that are used within the construction of the building to:1.Limit the growth and spread of fire within the building with use of fire ratedwalls and doors;2.Reduce the amount of damages of the building inflicted by the fire;3.Avoid the collapse of the building structure;4.Reduce the possible life and health risks of the building occupants and the firefighters;Therefore, passive fire protection provides the building with the strength towithstand fire for a certain period of time, ensuring the safe evacuation of itsoccupants and the safety of the building surrounding it.12
