Approved Supervised Sprinkler System (ASSS). An integrated network of hydraulically designed
piping system installed in a building, structure or facility with outlets arranged in a systematic
pattern. It automatically discharges water when activated by heat or combustion products of fire.
Automatic Fire Suppression System (AFSS). An integrated system of underground or overhead
piping connected to a source of extinguishing agent or medium, designed in accordance with fire
protection engineering standards to include, but not limited to Automatic Fire Sprinkler System
which when actuated by its automatic detecting device suppresses fire within the area protected
even without human intervention.
Compressed Gas System. An assembly of components, such as containers, reactors, pumps,
compressors and connecting piping and tubing, designed to contain, distribute or transport
compressed gases.
Class A Fire. Fires involving ordinary combustible materials such as wood, cloth, rubber and
plastics.
Class B Fire. Fires involving flammable liquids and gases.
Class C Fire. Fires involving energized electrical equipment.
Class D Fire. Fires involving combustible materials, such as sodium, magnesium, potassium, and
other similar materials.
Class K Fire. Fires in cooking appliances that involve combustible cooking media (vegetable or
animal oils and fats).
Fire. The active principle of burning, characterized by the heat and light of combustion.
Fire Alarm. Any visual or audible signal produced by a device or system to warn the occupants of
the building or firefighting elements of the presence or danger of fire.
Fire Alerting System. A fire alarm system activated by the presence of fire, where the signal is
transmitted to designated locations instead of sounding a general alarm.
Fire Area. The aggregate floor area enclosed and bounded by fire walls, fire barriers, exterior walls
or fire resistance-rated horizontal assemblies of a building.
Fire Barrier. A continuous membrane or a membrane with discontinuities created by protected
openings with a specified fire protection rating, where such membrane is designed and constructed
with a specified fire resistance rating to limit the spread of fire, that also restricts the movement of
smoke Fire Barrier Wall. Interior wall that extends from floor to floor or floor to roof, including
concealed and interstitial spaces. They are designed to sub-divide portions of the building, and can
be supported by structures, such as roofs, columns or floors. All support structures should have a
fire-resistance rating no less than that of the fire barrier they support. Fire barriers restrict the
initial flow of heat within the area of origin, which provides building occupants with adequate time
to evacuate to safe areas. These walls shall have at least three (3) hours fire resistance rating.
Fire Detection and Alarm System. A system that detects fire at the earliest stage, and gives an
alarm to alert the occupants so that appropriate action can be taken.
Fire Door. A fire resistive door prescribed for openings in fire separation walls or partitions.
Fire Resistance Rating. The duration that a material or construction can withstand the effect of a
standard fire test.
Fire Safety Compliance Report (FSCR). A written report composed of plans, specifications and
design analysis per building prepared by its Engineer/Architect-of-Record and Fire Safety
Practitioner.
Fire Safety Construction. Refers to the design and installation of walls, barriers, doors, windows,
vents, means of egress and other elements integral to and incorporated into a building or structure
in order to minimize danger to life from fire, smoke, fumes or panic before the building is evacuated.
These features are also designed to achieve, among others, safe and rapid evacuation of people and
properties through means of egress on construction, which are sealed from smoke or fire; and
confinement of fire or smoke in the room or floor of origin and delay their spread to other parts of
the building by means of smoke-sealed and fire resistant doors, walls and floors. It shall also mean
to include the treatment of building components or contents with flame retardant chemicals.
Fire Wall. An exterior wall designed to prevent the spread of fire, having a fire resistance rating of
not less than four (4) hours with sufficient structural stability to remain standing even if
construction on either side collapses under fire condition. Fire walls particularly erected above or
along property lines shall have absolutely no openings and shall extend above the roof to one meter
(1 m).
Occupancy. The purpose for which a building or portion thereof is used or intended to be used.
Occupant. Any person actually occupying and using a building or portions thereof by virtue of a
lease contract with the owner or administrator or by permission or sufferance of the latter.
Fixed Guideway Transit System. An electrified transportation system, utilizing a fixed guideway,
operating on right-of-way for the mass movement of passengers within a metropolitan area, and
consisting of its fixed guideways, transit vehicles, and other rolling stock; power systems; buildings;
stations; and other stationary and movable apparatus, equipment, appurtenances, and structures.
Passenger Rail System. A transportation system, utilizing a rail guideway, operating on right-ofway for the movement of passengers within and between metropolitan areas, and consisting of its
rail guideways, passenger rail vehicles, and other rolling stock; power systems; buildings; stations;
and other stationary and movable apparatus, equipment, appurtenances, and structures.
Portable Tank. Any closed vessel having a liquid capacity over two hundred twenty-seven liters
(227 L) and not intended for fixed installation
Sprinkler System. An integrated network of hydraulically designed piping system installed in a
building, structure or area with outlets arranged in a systematic pattern which automatically
discharges water when activated by heat or combustion products from a fire.
Standpipe System. A system of vertical pipes in a building to which fire hoses can be attached on
each floor, including a system by which water is made available to water outlets as needed.
Means of Egress. A continuous and unobstructed route of exit from one point in a building,
structure or facility to a public way consisting of three (3) distinct parts: exit, access and exit
discharge.
