The bow thruster tunnel is open to the sea and can flood rapidly, trapping personnel with no means of escape when the vessel is moving.

Question 83: Which signal indicates 'Man Overboard' on a ship's whistle?

• Five short blasts
• One prolonged blast
• Three long blasts
• Three short blasts (Correct answer)

Correct answer: Three short blasts

Three short blasts on the ship's whistle is the international signal indicating a person has fallen overboard.

Question 84: When entering a confined space suspected to contain a toxic atmosphere, what must be done before entry?

• Open all hatches and wait 10 minutes before entering
• Have a second crew member stand nearby outside the space
• Test the atmosphere and obtain a valid permit to work (Correct answer)
• Enter quickly and limit exposure time to under 5 minutes

Correct answer: Test the atmosphere and obtain a valid permit to work

Confined space entry requires atmospheric testing for oxygen, flammable gases, and toxic substances, plus a formal permit-to-work signed by a responsible officer.

Question 85: What is a 'citadel' in the context of anti-piracy measures?

• An armed escort vessel provided by naval forces
• A designated hardened safe room where crew shelter when a vessel is being boarded (Correct answer)
• A database of known pirate vessels maintained by naval intelligence
• An anti-piracy fence installed around the entire deck perimeter

Correct answer: A designated hardened safe room where crew shelter when a vessel is being boarded

A citadel is a pre-designated, hardened safe room or area where crew can lock themselves in and communicate with authorities if pirates board the vessel.

Question 86: What is the minimum safe oxygen concentration level in a confined space before entry without breathing apparatus?

• 19.5% (Correct answer)
• 17%
• 23%
• 21%

Correct answer: 19.5%

An oxygen concentration below 19.5% is considered oxygen-deficient and unsafe for entry without self-contained breathing apparatus.

Question 87: In a four-stroke diesel engine, during which stroke does combustion occur?

• Compression stroke at TDC
• Power (expansion) stroke (Correct answer)
• Suction stroke
• Exhaust stroke

Correct answer: Power (expansion) stroke

Combustion begins near TDC at the end of the compression stroke and the expanding gases drive the piston down during the power stroke.

Question 88: What is the correct action if a crew member discovers a fire in a cargo hold?

• Wait to confirm the fire before alerting others to avoid a false alarm
• Open the hold to fight the fire with portable extinguishers
• Sound the alarm, report to the bridge, and close all openings to the hold (Correct answer)
• Immediately flood the hold with water from a fire hose

Correct answer: Sound the alarm, report to the bridge, and close all openings to the hold

Sounding the alarm and closing openings to limit oxygen supply are the immediate priorities; fighting a hold fire alone is extremely dangerous.

Question 89: What does STCW require regarding the handover of a navigational watch?

Question 95: When using an AED on a casualty who is lying in water, what should you do first?

• Dry the chest only and apply pads while remaining in water
• Move the casualty to a dry surface before attaching pads (Correct answer)
• Use the AED immediately — water does not affect it
• Skip AED use and continue CPR only

Correct answer: Move the casualty to a dry surface before attaching pads

The casualty must be moved to a dry surface to prevent current dispersion through water and protect rescuers from shock.

Question 96: Which risk management approach is MOST effective for STCW professionals when evaluating potential workplace hazards?

• Relying solely on historical accident data
• Delegating all safety decisions to management
• Proactive hazard identification and assessment (Correct answer)
• Reactive analysis after incidents occur

Correct answer: Proactive hazard identification and assessment

Proactive hazard identification and assessment allows professionals to identify and mitigate risks before incidents occur, which is far more effective than reactive approaches that only address problems after they happen.

Question 97: What information must be included in a DSC distress alert?

• Vessel name, cargo manifest, and port of departure
• Flag state, classification society, and IMO number
• Nature of distress, position, time, and MMSI (Correct answer)
• Captain's name, crew count, and next port of call

Correct answer: Nature of distress, position, time, and MMSI

• Disability
• Dressing
• Danger (Correct answer)
• Defibrillation

Correct answer: Danger

The 'D' stands for Danger — always ensure the scene is safe for rescuers before approaching the casualty.

Question 100: When abandoning ship, what is the correct order of priority for survival craft?

• Use whichever is nearest
• Liferafts first, then lifeboats
• Deploy all simultaneously
• Lifeboats first, then liferafts (Correct answer)

Correct answer: Lifeboats first, then liferafts

Lifeboats are boarded first because they offer better protection and survival conditions; liferafts are used if lifeboats are unavailable or damaged.
