An AB collapses on deck and is unresponsive. He has a head injury. There is no doctor on board. Describe the CM's response.

A. MEDICAL EMERGENCY — CM RESPONSE: (1) IMMEDIATE: ensure the scene is safe (no electricity, no further injury risk). Do NOT move the casualty if spinal injury is possible (falling injury — head injury — potential spinal involvement); (2) CHECK RESPONSIVENESS: speak to him loudly; check for response; (3) CALL FOR HELP: shout for assistance — never leave the casualty alone in the first moments; (4) ABCs: Airway (open and clear), Breathing (is he breathing?), Circulation (carotid pulse?); (5) IF UNCONSCIOUS AND BREATHING: place in recovery position (lateral recumbent) — unless spinal injury suspected; (6) IF UNCONSCIOUS NOT BREATHING: start CPR immediately (30 compressions : 2 breaths ratio). Use the AED (Automated External Defibrillator) as soon as available; (7) NOTIFY MASTER IMMEDIATELY: medical emergency — master takes command responsibility; (8) TMAS (TELEMEDICAL ASSISTANCE SERVICE): contact TMAS immediately via GMDSS. Provide: casualty description, age, symptoms, history, vital signs, any medications found. A doctor will advise remotely; (9) SHIP CAPTAIN'S MEDICAL GUIDE: the definitive onboard medical reference (or MCA equivalent). Head injury section — monitoring for deterioration, Glasgow Coma Scale; (10) DIVERT: the master may order diversion to nearest port or request helicopter CASEVAC depending on TMAS advice; (11) DOCUMENTATION: maintain written record of observations — time, vital signs, changes in condition, treatment given, TMAS advice received; (12) STCW MEDICAL AID TRAINING: every officer must hold a Medical Aid training certificate — this covers exactly this scenario.

B. Call the company DPA first — they will coordinate medical assistance through the company's medical helpline. Do not contact TMAS directly.

C. CPR should not be started if the person has a head injury. Head injuries require total immobility and CPR creates movement. Wait for TMAS advice.

D. Administer ibuprofen for the head injury pain and confine the crew member to bed. Monitor for 24 hours before seeking further medical advice.

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.
