An AB needs to paint the mast and radar mast. This requires work at 15m above the deck. How do you manage this safety-critical task?

A. WORKING ALOFT — CM SAFETY MANAGEMENT: COSWP Chapter 16 and MLC Title 4: working aloft is a high-risk activity requiring formal risk assessment and permit. CM PROCEDURE: (1) RISK ASSESSMENT: conduct a written risk assessment — identify hazards (falling from height, falling objects onto crew below, electrical hazard from radar/radio equipment, weather), assess probability and severity, apply controls; (2) PERMIT TO WORK: complete a Working Aloft Permit — specifying: who will carry out the work; what work is to be done; height involved; safety equipment required; weather conditions limit; duration; responsible officer; emergency procedure; (3) WEATHER CHECK: working aloft must not be conducted in: wind above Beaufort 4 (recommended) or company SMS limit; rain or wet conditions that make surfaces slippery; reduced visibility; excessive vessel motion (if at sea); (4) PERSONAL FALL PROTECTION: the AB must wear a full-body harness (not just a safety belt) with a shock-absorbing lanyard. The harness must be tested and inspected before use; (5) STOP RADAR: CRITICAL — ensure radar scanners are STOPPED before approaching and LOCKED out. Rotating radar scanners can cause severe injury or death. Use LOTO (Lock Out/Tag Out) procedure; (6) STOP RADIO TRANSMISSIONS: alert radio operators — no high-power transmissions from antennas while person is near the top. RF burn risk; (7) SAFETY NETS/BARRIERS: if practicable, rig safety nets below the work area; rope off the deck area below to keep other crew clear of falling objects (paint cans, tools); (8) SUPERVISION: CM or bosun to supervise from deck level; (9) COMMUNICATION: maintain communication with the AB at all times during the work.

B. Painting the mast is routine seamanship work. Give the AB a paint pot and let them manage their own safety — ABs are trained for this work.

C. Stop the radar by switching it to standby mode. Standby mode reduces the radar rotation speed sufficiently to make it safe to work near the scanner.

D. Working aloft permits are only required for work above 25 metres. At 15 metres, standard PPE (safety helmet) is adequate without a formal permit.

A. MLC 2006 — CM CREW WELFARE OBLIGATIONS: MLC 2006 (Maritime Labour Convention, in force 2013) consolidates and updates 68 previous ILO maritime conventions. As the officer responsible for deck crew, the CM has specific obligations: (1) WORKING HOURS: ensure deck crew rest hours comply with MLC Standard A2.3 — minimum 10 hours rest per 24 hours, 77 hours per 7 days. Maintain accurate rest hour records. Never sign falsified records; (2) SAFE WORKING CONDITIONS: MLC Title 4 — ensure a safe workplace. Risk assessments must be completed for hazardous tasks. PPE must be provided and its use enforced; (3) WAGES: MLC Standard A2.2 — crew must be paid monthly (or agreed intervals) in full. CM should not withhold or deduct wages improperly; (4) FOOD AND CATERING: MLC Standard A3.2 — adequate food and potable water. Report to master if galley conditions or food quality is below standard; (5) ACCOMMODATION: MLC Standard A3.1 — report any accommodation deficiencies affecting deck crew to the master and DPA; (6) MEDICAL CARE: MLC Standard A4.1 — ensure crew have access to medical care. Know the location of the Medical Guide (Ship Captain's Medical Guide). Know the TMAS (Telemedical Assistance Service) number for advice; (7) COMPLAINT PROCEDURE: MLC Standard A5.1.5 — crew must have access to a complaint mechanism without fear of retaliation. CM must not suppress or discourage complaints; (8) REPATRIATION: MLC Standard A2.5 — abandoned crew must be repatriated at no cost to themselves. Know the procedure.

B. MLC 2006 only applies to vessels over 500 GT. The Chief Mate on smaller vessels has no MLC obligations toward crew welfare.

C. MLC welfare obligations are the master's responsibility. The Chief Mate's role is operational management of deck crew tasks only.

D. MLC 2006 is a flag state regulatory document. Port state obligations under MLC are administered by port authority officials — not ship officers.

A. NEW CREW SAFETY INDUCTION — CM RESPONSIBILITIES: SOLAS III/19 and ISM Code Section 6: new crew must receive a safety induction before being assigned duties. REQUIRED ELEMENTS: (1) MUSTER LIST: show the crew member their station on the muster/emergency list — what they must do in each emergency type (fire, flooding, abandon ship, man overboard); (2) LIFERAFT/LIFEBOAT: location and how to board their assigned survival craft; (3) IMMERSION SUIT: show where their personal immersion suit is stored; check it fits; demonstrate donning; (4) LIFEJACKET: location, how to don, how to operate the light and whistle; (5) FIRE EXTINGUISHERS: location of nearest portable extinguishers; how to use them (PIN, AIM, SQUEEZE, SWEEP); type of extinguisher and what it can/cannot be used on; (6) EMERGENCY EXITS AND ESCAPE ROUTES: at least two routes from their cabin and workplace; (7) ALARM SIGNALS: general emergency alarm (7 short + 1 long blast); abandon ship (7 short + 1 long on bell AND continuous on whistle); fire alarm (continuous bell); (8) PERMIT TO WORK SYSTEM: explanation of the PTW system — enclosed space entry, hot work, working aloft. No work without permit; (9) SMOKING POLICY: designated smoking areas only; (10) REPORTING: how to report a hazard or near-miss; (11) SIGN-OFF: the crew member must sign the induction record to confirm they received the briefing. Keep the signed record on file.

B. New crew safety induction is only required for officers. Ratings join the vessel and shadow experienced crew — the on-the-job experience constitutes their safety induction.

C. Safety induction can be delayed until the vessel reaches sea. In port, there are no safety risks for new crew and immediate induction is not required.

D. The bosun provides all safety inductions for deck ratings. The Chief Mate only provides inductions for junior officers and cadets.
