USCG FIRE FIGHTING CORRECT TEST PAPER
QUESTIONS AND ANSWERS SURE A+
✔✔hose couplings - ✔✔connect individual lengths of hose, connect to
hydrants/valves/nozzles, either threaded or nonthreaded
✔✔threaded couplings - ✔✔higbee indicators indicate proper alignment
✔✔nonthreaded couplings - ✔✔storz - neither female/male ends, face-to-face gasket
quick connect (cam-lock) - ensure locks are secured
✔✔wyes - ✔✔split stream into two hose streams
✔✔water thief - ✔✔divides one large line into several smaller hose lines
✔✔siamese - ✔✔combines two hose lines into one (2 female inlets/1 male outlet)
✔✔adaptors - ✔✔connect same size hoses with dissimilar threads
✔✔reducer - ✔✔attaches smaller hoses to larger hoses
✔✔hose jacket - ✔✔stops leaking section
, ✔✔fire pumps - ✔✔2 required on most vessels, 3 required on passenger vessels over
4000 gt
✔✔minimum pressure - ✔✔50psi (cargo), 75psi (tankers)
✔✔fire stations - ✔✔control valve, hose connection, hose rack
✔✔SCBA - ✔✔Self Contained Breathing Apparatus
✔✔emergency bypass mode - ✔✔releases a constant flow of air, used if regulator
malfunctions
✔✔fog stream/combination nozzle - ✔✔produce fine droplets of water, absorbs heat
quickly, creates water curtain
✔✔smooth-bore nozzle - ✔✔longer reach, deeper penetration, cannot produce a fog
pattern
✔✔other nozzles - ✔✔broken stream: piercing, cellar, water curtain
✔✔direct attack - ✔✔uses water most efficiently on free-burning fires
✔✔indirect attack - ✔✔used when entry is not possible due to intense heat
✔✔combination attack - ✔✔strategies from both direct/indirect attack
✔✔overhaul - ✔✔consists of activities to make sure no embers are still lit, conducted
once the main fire is extinguished, last phase of fire
✔✔dewatering - ✔✔external/internal drains, pumping equipment
✔✔What are SCBA bottles filled with? - ✔✔air (21% oxygen)
✔✔oxygen deficiency - ✔✔oxygen level is less than 19.5 %, achieved either when fire
consumes all available oxygen, or gases created by fire displace oxygen present
✔✔SCBA must be used in: - ✔✔enclosed areas with smoke, during overhaul, toxic
gases/oxygen deficiency present
✔✔PASS - ✔✔Personal Alert Safety System, alarm that sounds if you are motionless
for
✔✔smoke - ✔✔unburned/partially burned/completely burned substances
