1. While standing watch in the engine room during a coastal transit, an officer detects a
strong smell of burning insulation near the main switchboard. What is the immediate
operational priority?
A. Notify the Chief Engineer and log the incident in the engine room logbook
B. Locate the precise circuit breaker causing the smell before taking action
C. Sound the general alarm and inform the bridge of a potential electrical fire hazard
D. Rig a portable CO2 extinguisher and discharge it toward the switchboard area
Answer: C
The immediate priority upon detecting signs of a fire is to raise the alarm and notify the
bridge to ensure the safety of the vessel and start emergency response procedures.
Investigating or attempting to combat the fire before raising the alarm risks losing critical
time if the fire escalates rapidly.
2. A seafarer is instructed to enter a enclosed space that has been unventilated for several
days. Which initial step must be completed before entry is permitted?
A. Perform a visual inspection using an explosion-proof flashlight
B. Test the atmosphere at multiple levels using a calibrated multi-gas detector
C. Enter with a buddy who remains outside the space holding a lifeline
D. Run a supply fan for five minutes to flush out stagnant air
Answer: B
Atmospheric testing at high, middle, and low levels is mandatory prior to entering any
enclosed space to verify adequate oxygen content (typically 20.9%) and ensure toxic and
flammable gases are within safe limits. Visual inspection or short-term ventilation alone does
not guarantee a safe atmosphere.
,3. What is the primary purpose of an immersion suit on board a vessel operating in cold
waters?
A. Provide maximum buoyancy to keep the casualty afloat without a lifejacket
B. Reduce thermal body heat loss and prevent hypothermia upon immersion
C. Allow the wearer to swim long distances toward a rescue craft
D. Protect the wearer from chemical spills during abandoned ship procedures
Answer: B
Immersion suits are designed to insulate the body against cold water, significantly slowing
the rate of body heat loss and preventing hypothermia. While they provide buoyancy, their
main function is thermal protection.
4. According to STCW regulations, how often must emergency abandon ship drills be
conducted for crew members on cargo vessels?
A. Weekly
B. Monthly
C. Quarterly
D. Annually
Answer: B
SOLAS and STCW standards mandate that every crew member participate in at least one
abandon ship drill and one fire drill every month, or within 24 hours of leaving port if more
than 25% of the crew has not participated in drills on that specific ship in the previous month.
5. Which class of fire involves flammable liquids such as diesel oil, gasoline, or lubricating
oils?
A. Class A
B. Class B
C. Class C
D. Class D
,Answer: B
Class B fires involve flammable or combustible liquids, greases, tars, oils, and oil-based paints.
Class A involves ordinary combustibles, Class C involves electrical hazards, and Class D
involves combustible metals.
6. During a fire emergency on board, what is the primary operational objective of
boundary cooling?
A. Extinguish the primary fire by soaking adjacent compartments
B. Prevent the spread of fire into adjacent spaces via heat conduction
C. Reduce smoke density within the compartment on fire
D. Deprive the fire of oxygen by sealing off surrounding bulkheads
Answer: B
Boundary cooling involves applying water streams to bulkheads and decks adjacent to a fire
compartment to keep their temperatures below the ignition point of neighboring materials,
thereby preventing fire spread via heat transfer.
7. In accordance with maritime first aid standards, what is the first priority when
managing an unconscious casualty who is breathing normally?
A. Administer high-flow oxygen via a non-rebreather mask
B. Place the casualty in the recovery position to maintain a clear airway
C. Perform a full secondary head-to-toe physical assessment
D. Apply a cervical collar to immobilize the neck permanently
Answer: B
Placing an unconscious, breathing casualty in the recovery position uses gravity to keep the
tongue forward and allow fluids or vomit to drain, preventing airway obstruction and
aspiration.
8. Which item is required to be stowed near lifebuoys intended for quick release from the
navigation bridge?
A. A buoyant line of at least 30 meters and a whistle
, B. A self-igniting light and a self-activating smoke signal
C. A thermal protective aid and a sea anchor
D. A portable VHF radio and a radar reflector
Answer: B
Bridge wing quick-release lifebuoys must be fitted with both self-igniting lights and self-
activating smoke signals to mark the position of a man overboard during day or night
operations.
9. When operating a portable dry powder fire extinguisher, what is the correct technique
for extinguishing a surface liquid fire?
A. Direct the stream into the center of the liquid pool to break up the fuel
B. Aim at the base of the fire and sweep the nozzle from side to side
C. Spray high above the fire to let the powder fall like a blanket
D. Hold the nozzle vertically and discharge intermittently from maximum distance
Answer: B
Directing dry chemical powder at the base of the flame and using a side-to-side sweeping
motion interrupts the chemical chain reaction and smothers the flame base effectively
without splashing liquid fuel.
10. What is the main danger associated with using carbon dioxide (CO2) fixed fire-
extinguishing systems in engine rooms?
A. Rapid thermal shock causing structural failure of bulkheads
B. Asphyxiation of personnel due to displacement of oxygen
C. High risk of electrical shock to operators handling the discharge valves
D. Chemical toxicity leading to permanent neurological damage
Answer: B
CO2 extinguishes fire primarily by displacing oxygen. When discharged into a space, it reduces
oxygen levels below what is necessary to support human life, making complete evacuation
and accountability mandatory prior to release.
