MEK exit exam questions and answers — Set 7

Set 7 of the Marine Engineering Knowledge (MEK) exit exam bank — 15 of 195 questions, with the correct option marked and a one-line explanation for every one. Read it end to end, jump to a single set, or search it — then sit the same bank as a timed paper. The real DG Shipping exit exam is 30 marks with 15 to pass.

These are the bank's original groupings. Practising deals the whole bank out again every time you reshuffle, so a practice “Set 3” is a different 30 questions each time — the set numbers below are the source file's, and are only used here so the key stays navigable. Options are listed in their original order with fixed letters; when you practise, those move too.

Set 7 — 15 MEK exit exam questions with answers

1. Before re-starting a machine, following precautions to be taken...Mark the incorrect one

  • A. Replace the safety guard after starting the machine
  • B. Check that no tools have been left on or near the machine
  • C. Remove any warning notices
  • D. Restore the power supply
Answer: A — Replace the safety guard after starting the machine
Safety guards must be reinstalled and secured before starting any machine. Running machinery without guards exposes personnel to rotating parts and creates a severe safety hazard.

2. Dry full contact body resistance is about ______ ohms at 250V

  • A. 2000
  • B. 4000
  • C. 3000
  • D. 5000
Answer: A — 2000
The average electrical resistance of the human body when dry is approximately 2000 ohms. This value decreases significantly if the skin is wet, increasing the risk of fatal shock.

3. What is the minimum value of shock current (AC) which can be fatal

  • A. 35 mA
  • B. 20 mA
  • C. 15mA
  • D. 25 mA
Answer: C — 15mA
Current as low as 15mA can cause involuntary muscle contraction and interfere with cardiac function, making it a threshold for potentially fatal electric shock.

4. What documented record must be maintained on board following completion of tasks related to containment, isolation, and emergency response in Marine Engineering Knowledge?

  • A. No written record is required
  • B. Unsigned note on the shipboard notice board
  • C. Verbal update to port agent without logging
  • D. Entry in the official Deck or Engine Logbook recording date, time, and operational parameters
Answer: D — Entry in the official Deck or Engine Logbook recording date, time, and operational parameters
Official logbook entries provide mandatory legal documentation of shipboard safety tasks.

5. What regulation under STCW Code applies to Marine Engineering Knowledge mandatory minimum requirements?

  • A. SOLAS Chapter V Rule 10
  • B. Chapter III Regulation 5
  • C. MARPOL Annex I Regulation 12
  • D. Section A-VI/{sec} of STCW Code
Answer: D — Section A-VI/{sec} of STCW Code
STCW Code Chapter VI specifies mandatory standards for safety and emergency functions.

6. Under STCW standards for Marine Engineering Knowledge, how often must refresher training or evidence of competence be demonstrated?

  • A. Every 10 years
  • B. Every 2 years
  • C. Every 5 years
  • D. Annually
Answer: C — Every 5 years
STCW 2010 Manila Amendments require seafarers to demonstrate continued competence every 5 years.

7. What primary safety objective is governed by the Marine Engineering Knowledge module on board ship?

  • A. Minimizing port dues
  • B. Enhancing shipboard safety and emergency readiness
  • C. Automating engine control
  • D. Optimizing fuel consumption
Answer: B — Enhancing shipboard safety and emergency readiness
The core objective of STCW safety modules is protecting human life and vessel integrity.

8. What documented safety check must be performed before starting operations related to Marine Engineering Knowledge?

  • A. Risk assessment and toolbox meeting
  • B. Verbal request to port authority
  • C. Bridge sign-off without briefing
  • D. Engine logbook entry only
Answer: A — Risk assessment and toolbox meeting
Toolbox briefings and risk assessments ensure all personnel understand operational hazards.

9. What personal protective equipment (PPE) is mandatory during Marine Engineering Knowledge practical tasks?

  • A. Basic cotton coveralls only
  • B. Standard street clothes with safety boots
  • C. High-visibility vest only
  • D. Approved PPE meeting IMO/SOLAS standards
Answer: D — Approved PPE meeting IMO/SOLAS standards
Appropriate certified PPE protects personnel against specific task hazards.

10. Which international convention mandates compliance for Marine Engineering Knowledge operational procedures?

  • A. STCW Convention as amended
  • B. Tonnage Convention 1969
  • C. COLREGs 1972
  • D. Load Line Convention 1966
Answer: A — STCW Convention as amended
STCW governs training, certification, and watchkeeping standards worldwide.

11. In case of an emergency scenario during Marine Engineering Knowledge operations, what is the immediate first step?

  • A. Raise the alarm and notify Officer of the Watch / Duty Engineer
  • B. Log the event in diary
  • C. Evacuate vessel immediately without alert
  • D. Attempt to fix without informing others
Answer: A — Raise the alarm and notify Officer of the Watch / Duty Engineer
Promptly raising the alarm activates emergency response teams and master protocol.

12. What document contains emergency procedures and duties for crew members regarding Marine Engineering Knowledge?

  • A. Cargo Manifest
  • B. Muster List and Emergency Instructions
  • C. Oil Record Book Part I
  • D. Garbage Record Book
Answer: B — Muster List and Emergency Instructions
The Muster List specifies assigned duties and station locations for every crew member.

13. What key responsibility rests with seafarers participating in Marine Engineering Knowledge drills?

  • A. Observing without participating
  • B. Active participation and compliance with safety protocols
  • C. Bypassing safety gear for speed
  • D. Signing attendance without attending
Answer: B — Active participation and compliance with safety protocols
Realistic drill practice ensures effective performance during actual emergencies.

14. What log entry is required following completion of Marine Engineering Knowledge drills on board?

  • A. Official Deck / Engine Logbook entry recording date, drill type, and duration
  • B. No log entry required
  • C. Verbal update to port agent
  • D. Personal diary note
Answer: A — Official Deck / Engine Logbook entry recording date, drill type, and duration
SOLAS and flag state regulations require formal logbook documentation of all drills.

15. What type of personal protective equipment (PPE) is essential when handling containment, isolation, and emergency response under Marine Engineering Knowledge guidelines?

  • A. Standard street clothing with rubber gloves
  • B. Basic cotton coveralls without eye or foot protection
  • C. Certified task-specific PPE meeting SOLAS/IMO performance standards
  • D. High-visibility vest only
Answer: C — Certified task-specific PPE meeting SOLAS/IMO performance standards
Approved PPE protects personnel against specific physical and chemical hazards.
