Set 3 — 28 REFRESHER exit exam questions with answers

1. Fire hoses should always be stowed at the fire main in a manner which will allow

  • A. The nozzle end to be run out to the fire
  • B. All sections to be quickly drained
  • C. All sections to be quickly connected
  • D. The nozzle and fittings to be easily and quickly inspected
Answer: A — The nozzle end to be run out to the fire
Fire hoses are stowed at the hydrant so they can be run out rapidly toward the scene of a fire without kinks. This ensures that the crew can deploy the firefighting line immediately without losing time untangling or connecting sections.

2. What is the most vulnerable part of the fire main system?

  • A. Exposed hard piping
  • B. The hydrant valves
  • C. The fire pumps
  • D. The fire hose
Answer: D — The fire hose
Fire hoses are the most vulnerable component because they are made of flexible, woven material exposed to physical damage, abrasion, heat, and potential rotting. Regular inspection is required to ensure they do not burst under fire main pressure.

3. In what location MUST a duplicate fire control plan be located?

  • A. Chief Mate's Office
  • B. Crew Mess
  • C. Gangway
  • D. Engine Room
Answer: C — Gangway
Per SOLAS regulations, a duplicate of the fire control plan must be permanently stored in a weather-tight enclosure outside the deckhouse. This allows firefighters coming from the shore to quickly assess the ship's fire safety arrangements.

4. A vessel's fire control plan shall be

  • A. Permanently posted for the guidance of ship's officers
  • B. Posted every 150 feet along the most continuous deck on the vessel
  • C. Given to each crew member in booklet form
  • D. Translated into three languages: English, French and Spanish
Answer: A — Permanently posted for the guidance of ship's officers
The fire control plan serves as a vital document for officers and firefighters to understand the location of fire detection, control, and containment systems. It must be permanently posted to ensure it is always available for reference during emergencies.

5. The muster list shows each rig hand's muster station, his duties during abandonment, basic instructions, and

  • A. Instructions for lowering the survival craft
  • B. The time each weekly drill will be held
  • C. Work schedule
  • D. All emergency signals
Answer: D — All emergency signals
The muster list defines the emergency organization of the ship. It must clearly outline the specific muster station for each crew member, their abandonment duties, and the universal emergency signals so all personnel know how to react instantly.

6. A fireman's outfit carried onboard cargo vessels, must have a

  • A. Canister-type gas mask
  • B. Self-contained breathing apparatus
  • C. Combustible gas indicator
  • D. Fresh-air breathing apparatus
Answer: B — Self-contained breathing apparatus
Cargo vessels are required to carry self-contained breathing apparatus (SCBA) as part of the fireman's outfit. Unlike canister masks, SCBAs provide an independent supply of breathable air, essential for entering smoke-filled or oxygen-deficient spaces.

7. The international shore connection

  • A. Satisfies pollution prevention requirements
  • B. Permits discharge of waste oil to shore facilities
  • C. Allows hookup of firefighting water from shore facilities
  • D. Allows emergency use of the fire main for de-ballasting
Answer: C — Allows hookup of firefighting water from shore facilities
The International Shore Connection (ISC) is a universal flange that allows shore-based fire services to connect their hoses to the ship’s fire main. This enables shore teams to supply water to the ship if the internal pumps fail.

8. Automatic fire dampers in ventilation systems are operated by use of

  • A. Fusible links
  • B. Remotely operated valves
  • C. Heat or smoke detectors
  • D. CO2 system pressure switches
Answer: A — Fusible links
Fusible links are heat-sensitive components designed to melt at a specific temperature. When they melt, the tension holding the damper open is released, allowing the fire damper to close automatically and isolate ventilation ducts to prevent fire spread.

9. If passengers are on board when an abandon ship drill is carried out, they should

  • A. Stay out of the way and do what they want
  • B. Watch
  • C. Take part
  • D. Go to their quarters
Answer: C — Take part
SOLAS regulations mandate that all passengers must participate in abandon ship drills. This ensures they are familiar with their lifejacket donning procedures, the emergency signal, and the route to their designated assembly stations.

10. Which type of extinguisher is hard to recharge onboard?

  • A. FOAM
  • B. CO2
  • C. WATER TYPE
  • D. DCP
Answer: B — CO2
CO2 extinguishers are difficult to recharge onboard because they require specialized high-pressure pumping equipment, chilled CO2 reservoirs, and precise weighing scales. Most vessels carry spare cylinders instead of attempting to recharge them.

11. What is the duration of EEBD?

  • A. 05 mins
  • B. 12 mins
  • C. 10 Min.
  • D. 8 mins
Answer: C — 10 Min.
Emergency Escape Breathing Devices (EEBD) are designed to provide a short duration of air to allow personnel to escape from a smoke-filled space. SOLAS requires a minimum service duration of at least 10 minutes.

12. What action should be taken immediately after a fire has been extinguished?

  • A. They are not a hazard unless ignited
  • B. They are not a hazard
  • C. They generate their own oxygen when ignited and difficult to extinguish
  • D. They are liable to spontaneous combustion
Answer: C — They generate their own oxygen when ignited and difficult to extinguish
Certain materials involved in fires (like some chemicals or specific fuels) can be self-oxidizing. These require specialized extinguishing methods because they do not rely on atmospheric oxygen and are notoriously difficult to suppress once ignited.

13. There are two disadvantages to CO2 when used as a total flooding firefighting agent. One of them is extinguishing concentration will not support human life and

  • A. The lack of cooling effect on heated materials
  • B. There is no effect on class A fire even in an enclosed space
  • C. It breaks down under extreme heat to form poisonous gases
  • D. It cannot be used in a dead ship situation without electrical power available to CO2 pump
Answer: A — The lack of cooling effect on heated materials
CO2 is an asphyxiant that displaces oxygen, making it deadly in enclosed spaces. A major disadvantage is its lack of cooling capacity, meaning that once the CO2 gas dissipates, the hot fuel may reignite if the surfaces have not cooled down.

14. Foam tends to extinguish fire by

  • A. Releasing large amount of CO2
  • B. Chemically absorbing oxygen
  • C. None of the above
  • D. Smothering the burning material
Answer: D — Smothering the burning material
Foam extinguishes fires primarily by creating a coherent blanket that 'smothers' the fire, cutting off the supply of oxygen to the burning liquid surface and preventing flammable vapors from escaping.

15. If restricted visibility is encountered in an accommodation fire, you would

  • A. Stand up straight to keep your head above the smoke
  • B. Carry a torch
  • C. Use a fan to blow the smoke and flames
  • D. Rig lifelines to assist a retreat
Answer: D — Rig lifelines to assist a retreat
In smoke-filled compartments with limited visibility, lifelines are essential for safety. They guide firefighters back to the exit point, ensuring that even if they become disoriented or visibility drops to zero, they can find their way out.

16. Firefighters should come back from the area

  • A. After 10 mins of firefighting
  • B. Upon instruction from another firefighter
  • C. None of the above
  • D. Upon hearing the warning sound from SCBA
Answer: D — Upon hearing the warning sound from SCBA
The SCBA's low-pressure warning alarm is a critical safety device that triggers when the air cylinder is nearing depletion. Firefighters must immediately withdraw from the hazardous zone upon hearing this signal to ensure they reach safety with a reserve of air.

17. In portable fire extinguishers, PASS stands for

  • A. Pass, At, Sure, Speed
  • B. Pull, Aim, Squeeze, Sweep
  • C. Pass, Aim, Squeeze, Sweep
  • D. Pass, Aim, Shut, Sit
Answer: B — Pull, Aim, Squeeze, Sweep
PASS is the standard acronym for operating a fire extinguisher: Pull the pin, Aim the nozzle, Squeeze the lever, and Sweep the agent across the base of the fire.

18. What is the maximum weight of a portable fire extinguisher?

  • A. 16 Kg
  • B. 25 Kg
  • C. 12 Kg
  • D. 23 Kg
