STCW Basic Safety Training (A-VI/1) — Study Guide

STCW Basic Safety Training (A-VI/1) — Study Guide

Credential: STCW Basic Safety Training — Certificates of Proficiency under STCW Code Section A-VI/1 (plus security-awareness training per A-VI/6 as amended) Issuing body: Approved maritime training providers; certificates recognized by flag-state administrations under the IMO STCW Convention (STCW-78, as amended, including the 2010 Manila Amendments) Jurisdiction: International (flag-state implemented) Level: Entry — required of all seafarers with designated safety or pollution-prevention duties Prerequisites: None (no sea time, no prior certificate). Medical fitness certificate is practically required alongside. Renewal: Refresher training in Personal Survival Techniques and Fire Prevention & Fire Fighting within the previous 5 years (mandatory since the Manila Amendments' full implementation, 1 January 2017 — flag states require evidence of updated training); other elements do not expire but employers and flag states expect currency.

1. What BST is and why it is mandatory

STCW Regulation VI/1 requires every seafarer to receive familiarization and basic training in survival, firefighting, first aid, and personal safety before being assigned shipboard duties involving safety or pollution prevention. The 2010 Manila Amendments added a decisive change: it is no longer enough to have trained once — the practical survival and firefighting skills must be revalidated every five years, because regulators recognized that crews never launch life rafts or fight real fires during routine monthly drills. In the US, the Coast Guard implements this through approved courses and the National Maritime Center (NMC) checklists; your BST certificates are prerequisites for virtually every Merchant Mariner Credential endorsement.

2. Pathway: how it is earned

1. Book an approved course. Choose a training provider approved by your flag administration (in the US, USCG-approved schools; in the UK, MCA-approved). The full BST week is typically 5 days; refresher/updater courses for PST + FPFF run ~2–3 days.
2. Complete the four A-VI/1 elements (each assessed — practical demonstration plus written assessment):
   • Personal Survival Techniques (PST) — Table A-VI/1-1: survival craft, lifejackets, immersion suits, emergency signals, helicopter rescue.
   • Fire Prevention and Fire Fighting (FPFF) — Table A-VI/1-2: fire theory, extinguishing agents, fixed systems, breathing apparatus, live-fire exercise.
   • Elementary First Aid (EFA) — Table A-VI/1-3: basic life support, bleeding, shock, burns, hypothermia, casualty handling.
   • Personal Safety and Social Responsibilities (PSSR) — Table A-VI/1-4: safe working practices, pollution prevention, human relationships, fatigue, harassment, drug/alcohol policy.
3. Complete security-awareness training (STCW A-VI/6-1; the Manila Amendments made security training mandatory for all seafarers; those with designated security duties take the fuller A-VI/6-2 course).
4. Receive Certificates of Proficiency (documentary proof, not a CoC endorsement) and present them with your MMC application.
5. Revalidate: within every 5-year cycle, complete PST and FPFF refresher training (or demonstrate the competencies through approved sea-service-plus-assessment routes where the flag state allows). Since 2017, you must carry evidence of updated training within the last five years.

3. Knowledge domains

3a. Personal Survival Techniques — the physics of staying alive

• Why immersion kills fast: cold-water shock (gasp reflex and cardiac stress in the first 1–3 minutes), then cold incapacitation (loss of useful muscle function within ~15–30 minutes in near-freezing water), then hypothermia. The theory behind every drill: minimize heat loss (HELP position — heat escape lessening posture; huddle with others), maximize flotation time, maximize detectability.
• Survival craft: totally/partially enclosed lifeboats, free-fall lifeboats, liferafts (davit-launched and throw-overboard). Know the launching sequence, the painter's function, and the hydrostatic release unit (HRU): it cuts the lashing at ~1.5–4 m depth so a float-free raft inflates if the ship sinks before manual launching.
• Lifejackets and immersion suits: donning within 1 minute (lifejacket) — the standard the drill is timed against; immersion suit reduces heat loss and provides buoyancy but is not a substitute for the raft.
• Emergency signals: pyrotechnics (red parachute rockets, hand flares, buoyant smoke), EPIRB (406 MHz, satellite alerting via COSPAS-SARSAT with vessel ID), SART (9 GHz radar transponder that paints 12 dots on a rescuing vessel's radar).
• Helicopter rescue: the hi-line technique, never securing the winch hook to yourself or the vessel (static discharge), the helicopter's downdraft and noise discipline.

3b. Fire Prevention and Fire Fighting — chemistry under pressure

• The fire triangle/tetrahedron: fuel + oxygen + heat (+ chemical chain reaction). Removing any leg extinguishes the fire; the tetrahedron explains why some agents (halon replacements like FM-200/Novec, dry chemical) work by interrupting the chain reaction rather than by cooling or smothering.
• Fire classes: A (ordinary combustibles — water/foam), B (flammable liquids — foam smothers; never water jet on a burning liquid, it spreads the fire), C (electrical — de-energize first, then CO₂/dry chemical; water on energized equipment is a lethal trap), D (combustible metals — special dry powder only), F/K (cooking oils — wet chemical).
• Shipboard fire systems: fixed CO₂ flooding (know the two-stage release: alarm then discharge, and that the space must be evacuated and sealed — CO₂ kills people before it kills fire), foam systems, water mist/sprinkler, fire detection (smoke, heat, flame detectors and their limitations — e.g., smoke detectors in dusty cargo holds false-alarm).
• Breathing apparatus (BA): positive-pressure SCBA; the exam's favorite trap is the low-air warning whistle — you withdraw at the warning, not after. Search techniques, lifeline signals, and the two-person minimum rule.
• The live-fire exercise (required for the certificate): extinguisher selection and approach (upwind, aim at base of flames, sweep), hose handling, and compartment entry. Strategy note: in the assessment, narrate what you are doing — assessors score the decision sequence.

3c. Elementary First Aid — keeping someone alive until help arrives

• DRSABCD / primary survey: Danger, Response, Send for help, Airway, Breathing, CPR, Defibrillation. Compression rate 100–120/min, depth 5–6 cm for adults — these numbers are examined.
• Bleeding and shock: direct pressure, elevation, tourniquet as a last resort for life-threatening limb bleeding; shock signs (pale, cold, clammy, rapid weak pulse) and management (lie flat, keep warm, no food/drink, treat the cause).
• Burns, fractures, hypothermia, drowning: cool burns with running water; immobilize fractures; gradual rewarming for hypothermia (no alcohol, handle gently — a cold heart fibrillates easily); drowning resuscitation priorities.
• Shipboard reality: the nearest hospital is hours to days away — EFA's purpose is stabilization and casualty evacuation preparation, not definitive care.

3d. Personal Safety and Social Responsibilities — the human system

• Safe working practices: enclosed-space entry (the single biggest killer of seafarers after drowning — permit, atmosphere testing: O₂ 20.9% normal, test for toxic gases and flammables, ventilation, attendant, rescue plan, BA on standby); working aloft; mooring operations; lockout/tagout.
• Pollution prevention: MARPOL basics every rating must know — no discharge of oil (15 ppm bilge-water limit with OWS and oil record book), garbage disposal rules (plastics never), sewage and air-emission basics.
• Human element: fatigue management (STCW rest-hour rules: minimum 10 hours rest in 24, 77 in 7 days, split into no more than 2 periods with one ≥ 6 hours), alcohol/drug policy, harassment and bullying, multicultural crew communication.

3e. Security awareness (A-VI/6)

• Know: the ISPS Code framework — ship security levels (1 normal, 2 heightened, 3 exceptional), the SSO (Ship Security Officer) vs. crew roles, restricted areas, screening of persons/stores, piracy/armed-robbery response (citadel, BMP — Best Management Practices), and reporting (SSAS — ship security alert system).

4. Key numbers and rules (memorize these)

• Lifejacket donning: ≤ 1 minute, unassisted.
• HRU release depth: ~1.5–4 m.
• CPR: 100–120 compressions/min, 5–6 cm depth, 30:2 ratio.
• STCW rest hours: ≥ 10 h per 24 h; ≥ 77 h per 7 days; ≤ 2 rest periods, one ≥ 6 h.
• Enclosed space: O₂ between 20.9% nominal; test O₂, toxics, flammables in that order of consequence; never enter to rescue without BA (the would-be rescuer becomes the second casualty — the exam's classic scenario question).
• Fire classes and agents: A-water/foam; B-foam (no water jet); C-de-energize + CO₂/dry chem; D-special powder; F/K-wet chemical.
• Pyrotechnics: red = distress. Orange smoke = daytime. Never fire a parachute rocket toward the rescue craft/helicopter.

5. Worked examples

Example 1 — Enclosed-space scenario (assessment favorite). A rating collapses in a chain locker. Your actions, in order: (1) raise the alarm — do NOT enter; (2) muster the rescue team with BA; (3) test/ventilate if not already done; (4) BA-equipped entry with lifeline and attendant; (5) extract to fresh air; (6) primary survey and EFA. The scoring point: step 1, not step 4. Entering unprotected fails the assessment immediately, however brave.

Example 2 — Fire-class selection. A galley deep-fat fryer ignites. Correct: smother with the fire blanket if small; wet-chemical extinguisher (Class F/K) — it cools and saponifies the oil surface. Wrong answers the assessor is listening for: water (explosive steam, spreads burning oil), CO₂ alone (knocks down flame but oil re-ignites — no cooling).

Example 3 — Survival-craft decision. Ship is listing 25° and the order to abandon is given; your assigned davit-launched raft is on the high side, now 8 m above the water. Correct reasoning: launching from the high side risks the raft swinging against the hull; move to the low-side/lee station per the muster list if time permits, or use throw-overboard rafts/ float-free arrangements. The principle: follow the muster list, but adapt to the ship's attitude — drills assume an upright ship; casualties don't.

Example 4 — Rest-hour compliance check. A watchkeeper's log shows 8 h rest in the last 24 h with the longest continuous period 5 h. Compliant? No: fails both the 10-hour minimum and the 6-hour continuous-period rule. The DPA/master must re-plan the watch — fatigue non-compliance is detainable under port-state control.

6. Standards and regulations cross-reference

• STCW Convention & Code (Reg VI/1, VI/6; Sections A-VI/1, A-VI/6; Manila Amendments): the entire legal basis. Know the regulation/code-section mapping — examiners and auditors cite sections, not vibes.
• SOLAS Chapter III (Life-saving appliances and arrangements): the equipment BST trains you to use — LSA Code specifications, muster lists, abandon-ship drills (weekly), enclosed-space rescue drills.
• SOLAS Chapter II-2 (Fire protection): fixed systems, firefighter's outfits, fire control plans — the FPFF domain's regulatory home.
• MARPOL (all annexes at awareness level): pollution-prevention duties from PSSR; Annex I (oil, 15 ppm) and Annex V (garbage) are the ones ratings get questioned on.
• ISM Code: the safety-management system that turns BST skills into procedures — drills, familiarization (STCW I/14 ship-specific), near-miss reporting.
• MLC 2006: rest hours, medical care, and the requirement that all seafarers hold medical fitness certificates.

7. Pitfalls and exam strategy

• The two classic scenario traps: (1) the collapsed colleague in an enclosed space — answer is always alarm + BA team, never solo entry; (2) water on a Class B or electrical fire — always wrong.
• BA air management: withdraw at the low-pressure warning, plan air for exit as well as entry (rule of thirds in spirit: in, work, out).
• Don't confuse certificates: BST gives Certificates of Proficiency (VI/1); officer licenses are Certificates of Competency (I/2, III/1). Using the wrong term in an oral or application signals you don't understand the STCW structure.
• Revalidation trap: PST and FPFF refresher (not the full course) is the requirement — but if you let it lapse beyond the flag state's grace provisions, you may need the full course again. Track your dates; the NMC will not remind you.
• Assessment strategy: practical assessments are pass/fail on safety-critical steps — a perfect hose drill with a missed BA check fails. Verbalize checks ("checking cylinder pressure… 270 bar, above minimum") so the assessor hears the safety logic.

8. Practice problems (with answers)

1. State the four A-VI/1 elements and the revalidation requirement for each. Answer: PST, FPFF, EFA, PSSR; PST and FPFF require refresher/updated training within the previous 5 years (post-Manila, enforced from 1 Jan 2017); EFA and PSSR do not expire but currency is expected.
2. You find a crewmate unconscious in a ballast tank. List your first four actions in order. Answer: raise the alarm; do not enter; muster BA rescue team; ventilate/test atmosphere — then BA entry with lifeline and attendant.
3. A switchboard fire is reported. Which extinguishing agent, and what is the mandatory first step? Answer: de-energize the switchboard first; then CO₂ or dry chemical (Class C). Water or foam on energized equipment is prohibited.
4. Compute rest-hour compliance: a seafarer records 9 h rest in 24 h in two periods of 5 h and 4 h. Answer: non-compliant — below the 10-hour minimum and neither period reaches 6 hours.
5. Your liferaft station is on the high side of a 20° list. What do you do? Answer: attempt the lee/low-side station per muster list if safe and time permits; otherwise use throw-overboard/float-free rafts; never ride a davit launch swinging against the hull.
6. What does the SART do, and on what frequency? Answer: 9 GHz radar transponder; when interrogated by a ship's/Aircraft's X-band radar it paints a distinctive 12-dot line on the PPI, homing rescuers to the survival craft.
