IV. FIRE FIGHTING SYSTEM Question With Answers
Fire fighting system: an activity of prevention during a fire spread in building, home or warehouse with the use of proper fi
safety equipment like extinguisher, hose reels, fire monitors, nozzles and hose pipes.
1. Wet Fire Sprinkler Systems: MOST COMMON, TRADITIONAL, 70°C up, employs automatic sprinklers
attached to a piping system connected to a water supply; water discharges immediately from sprinklers opened by a
fire; only those sprinklers which have been operated by heat over the fire will discharge water; most common form
of fire sprinkler; traditional type of fire sprinkler where the sprinkler pipes are filled with pressurized water that will
immediately, discharge when a fire occurs.
Dry Pipe Systems: NO WATER, DETECTS NITROGEN employs automatic sprinklers attached to a piping
system containing air or nitrogen under pressure; when released, the water flows into the piping system and discharges
only from those sprinklers which have been operated by the fire.
2. Special Hazard Fire Protection Systems: SPECIAL AREAS, designed to detect and extinguish fires
in locations where standard suppression systems are not appropriate or adequate; any fire protection system that is
designed to protect a particularly sensitive or valuable asset, or that is used in an application where fire sprinklers are
not appropriate.
3. Dry Chemical Fire Suppression Systems: MUCH SENSITIVE SYSTEM, pressured dry chemicals,
used in conjunction with the proper detection system can extinguish a fire before it; becomes detectable to the eye.
4. Gaseous Fire Suppression Systems: CARBON, FIRE EXTINGUISHER, carbon dioxide is a clean and
non-flammable gas (used as a fire-extinguishing agent); eflciently and ettectively extinguishes fires without leaving
any toxic or liquid residue that might damage property or equipment; sodium bicarbonate (NaHCO3, baking soda),
potassium bicarbonate (KHCO3, nearly identical to bakingsoda), or monoammonium phosphate ((NH4)H2PO4)
5. Foam Fire Suppression Systems: NOT GASEOUS, FOR GASOLINE BECAUSE GASOLINE CANNOT
BE SUPPRESSED WITH WATER, Foam extinguishing systems are ettective for rapidly controlling and extinguishing
flammable liquid fires.
6. SIAMESE CONNECTION: connected to hydrant/same nozzle/hose fitting with clapper valves
7. WYE: hose connection with two-gated outlets.
8. FIRE SPRINKLER SYSTEM: a system for protecting a building against fire by means of overhead pipes
, which convey an extinguishing fluid (such as water) to heat-activated outlets; an active fire protection measure,
consisting of a water supply system, providing adequate pressure and flow rate to a water distribution piping system,
onto which fire sprinklers are connected.
9. STANDPIPE SYTEM: a vertical pipe or a reservoir into which water is pumped to give it a head; installed in
buildings to help firefighters deploy attack hose lines quickly and with adequate water pressure and volume. They may
be designed for heavy stream applications, first aid fire appliances, or have features of both.
