MOD A FIREFIGHTER LATEST 2026 GUIDE QUESTIONS AND
SOLUTIONS GUARANTEE A+
✔✔10. Safety tips for fire hazards: - ✔✔A. Stay low when entering burning
buildings/rooms.
B. Check closed doors for heat.
C. Proper ventilation (top).
D. Proper gear (full bunker gear and SCBA).
E. Do not disturb the thermal layer.
F. Avoid elevators, and when using stairs, spread your weight edge to edge.
G. Do not disturb the thermal layer. (don't apply water to the upper thermal layer,
properly ventilate at the top, direct fire stream at the fire base)
✔✔11. Classifications of Fires: - ✔✔A. CLASS A - wood, paper, rubber, plastic.
B. CLASS B - liquids, greases, gases.
C. CLASS C - live electrical equipment.
✔✔SAFETY/SCBA - ✔✔...
✔✔1. Hazardous environments requiring the use of SCBA: - ✔✔A. Smoke.
B. Oxygen deficiency.
C. Elevated temperatures.
✔✔2. What are some examples of commonly found fire gases? - ✔✔A. Phosgene -
colorless, tasteless, disagreeable odor. Produced when Freon comes in contact with
flame.
B. Carbon Monoxide ( CO ) - colorless, odorless. More fire deaths occur from exposure
to carbon monoxide than any other product of combustion. Symptoms include:
headache, dizziness, nausea, vomiting, cherry red skin.
C. Hydrogen Chloride - colorless, pungent odor. Symptoms include: labored breathing
and suffocation.
D. Carbon Dioxide ( CO2 ) - nonflammable, colorless, odorless. Can cause death within
a few minutes at concentrations greater than 10% - 12%.
E. Nitrogen Dioxide - reddish brown in color. Symptoms include: arterial dilation, blood
pressure variations, dizziness and headache.
F. Hydrogen Cyanide - colorless, almond odor. Deadly!
✔✔3. List two physical requirements of an SCBA user: - ✔✔A. Physical - sound
physical condition, maximize amount of work that can be performed, maximize available
air supply.
B. Agility - must be agile as the unit will restrict wearer's movements, will affect balance.
✔✔4. What are the limitations of using an SCBA? - ✔✔A. Visibility.
B. Mobility.
, ✔✔5. What are the basic components of an SCBA? - ✔✔A. Harness.
B. Air cylinder.
C. Regulator.
D. Face Piece.
✔✔6. SCBA - ✔✔can either open or closed circuit SCBA's.
✔✔7. The low air alarm will sound when? - ✔✔one quarter of the air remains in the
SCBA.
✔✔8. SCBA hold - ✔✔45 cubic feet of air, and the maximum PSI is 2216. Our SCBA
are rated for 30 minutes, however expected use is 12-18 minutes.
✔✔9. What are daily inspection items on the SCBA?
(per NFPA 1404 and NFPA 1500) - ✔✔A. Gauges are within 100 PSI of each other.
B. Low pressure alarm sounds.
C. Straps in good condition, and fully extended.
D. All hoses are connected, and tight.
E. SCBA inspection should be done after each use, weekly, monthly and annually.
F. Full cylinder (minimum 90%------below 2100)
G. Face piece is clean and operational.
H. Operate bypass and mainline valves, return bypass to closed position after testing.
✔✔10. The regulator reduces cylinder PSI to slightly above atmospheric pressure -
✔✔(approximately 14.7 PSI).
✔✔11. Cascade Storage System (SCBA recharging system): - ✔✔A. Three or more 300
cubic foot cylinders.
B. Used for storage of compressed air.
C. Open cylinders one at a time during filling of SCBA bottles.
✔✔12. Full protective equipment: - ✔✔A. Helmut - protects head from impact and
punctures.
B. Protective Hood - protects portions of face, ears and neck from burns.
C. Coat & Trousers - protects trunk and limbs against cuts, abrasions and burns.
D. Gloves - protects hands from cuts, wounds and burns.
E. Boots - protects feet from burns and punctures.
F. Eye Protection - protects eyes from flying particles or liquids.
G. Hearing Protection - limits noise induced damage to ears.
H. SCBA (self-contained breathing apparatus) - protects face and lungs from toxic
smoke and products of combustion.
I. PASS (personal alert safety system) - emits loud shriek if the firefighter should
collapse or remain motionless for approximately 30 seconds.
