What is Basic Safety Training (BST) and who needs it?

STCW Basic Safety Training (BST) consists of four mandatory elements that every seafarer must complete before serving on a vessel 500 GT or more: (1) Personal Survival Techniques — STCW Table A-VI/1-1; (2) Fire Prevention and Firefighting — Table A-VI/1-2; (3) Elementary First Aid — Table A-VI/1-3; (4) Personal Safety and Social Responsibilities — Table A-VI/1-4. BST applies to all seafarers regardless of rank — deckhands, engineers, catering staff, and officers must all hold current BST certification. In the US, BST certificates expire after five years and require refresher training for renewal. Many maritime training centers offer BST as a combined course lasting 4-5 days with both classroom and practical components.

What are the STCW rest hours requirements and why do they matter?

STCW requires minimum rest hours to prevent fatigue-related accidents at sea. The minimum rest requirements are: (1) 10 hours of rest in any 24-hour period; (2) 77 hours of rest in any 7-day period. Rest may be divided into no more than two periods, one of which must be at least 6 hours. These requirements may only be suspended by the master when the vessel is in a "safe haven" or when the officer of the watch deems an immediate threat to safety, ship, cargo, or environment requires override — and the suspended rest must be compensated. The master is responsible for ensuring rest records are maintained and accessible for port state control inspection. Violations can result in detentions. Fatigue is cited as a contributing factor in a significant percentage of maritime accidents.

What is an EPIRB and how does it work?

An EPIRB (Emergency Position-Indicating Radio Beacon) is a satellite emergency distress transmitter required on SOLAS vessels. When activated — manually or automatically when released from its float-free bracket at approximately 4 meters depth — the EPIRB transmits a 406 MHz distress signal to the Cospas-Sarsat satellite system, which relays it to MRCC (Maritime Rescue Coordination Centers) with the vessel's identity (via encoded registration data) and position (via GPS integration in modern EPIRBs). Category I EPIRBs are float-free automatic — they release and activate automatically when the vessel sinks. Category II require manual activation or manual water immersion activation. EPIRBs must be registered with the national authority (NOAA in the US) so responders know the vessel's identity and emergency contacts.

What is the difference between a SART and an AIS-SART?

A SART (Search and Rescue Transponder) is a radar-activated device that responds to 9 GHz X-band radar signals from ships and helicopters by transmitting a series of blips that appear as a line of 12 dots on the radar screen, leading rescuers to the survivor's location. SARTs must be activated manually and carried in a survival craft or liferaft. An AIS-SART (AIS Search and Rescue Transmitter) uses the Automatic Identification System (AIS) to broadcast a distress position signal on VHF channels 87B and 88B, which is displayed on AIS receivers including Electronic Chart Display systems aboard ships. AIS-SARTs are more modern and can provide a position with greater precision because they use GPS rather than radar reflection, but they require the rescuing vessel to have an AIS display. Both can be carried together for complementary coverage.

STCW Practice Test PDF – Free Printable Maritime Standards of Training Exam Prep

Preparing for the STCW (Standards of Training, Certification and Watchkeeping for Seafarers) certification? A printable STCW practice test PDF gives you an offline format to review Basic Safety Training requirements, survival at sea procedures, fire prevention and firefighting, elementary first aid, and the IMO maritime standards that STCW examinations assess. STCW certification is internationally required for all merchant seafarers working on vessels 500 GT or more, meaning it is a legal requirement for employment in commercial maritime. This page provides a free PDF download and a comprehensive STCW exam preparation guide.

The STCW Convention is administered by the International Maritime Organization (IMO) and establishes minimum international standards for seafarer training, certification, and watchkeeping. The 2010 Manila Amendments updated competency requirements and added new certificates for tanker operations and passenger ship safety. In the United States, the U.S. Coast Guard (USCG) administers STCW certification under 46 CFR and issues Merchant Mariner Credentials (MMC).

STCW Exam Content Areas

Your STCW practice test PDF covers the knowledge areas tested in STCW Basic Safety Training assessments and officer-level certification examinations.

Personal Survival Techniques (STCW A-VI/1-1)

Personal survival techniques cover emergency procedures when abandoning ship: survival craft types (enclosed lifeboats — self-righting capability, diesel engine, positive pressure ventilation; open lifeboats; rescue boats — rigid or inflatable, minimum 4-person capacity; liferafts — SOLAS inflatable liferafts, hydrostatic release units for automatic deployment at 4 meters depth), muster stations and emergency signals (general emergency signal — 7 short + 1 long blast; crew duties at muster stations; abandon ship command), liferaft inflation and boarding (throwing overboard, inflation by painter line pull, approaching from windward, proper boarding technique — one at a time, avoid jumping on), survival in water (correct lifebuoy approach — don't swim toward, let the ring come to you; HELP position — Heat Escape Lessening Posture for individual; HUDDLE position for group; sea anchor deployment), and survival priorities on a liferaft (protecting from exposure, signaling for rescue — EPIRB, SART radar transponder, flares — parachute vs. hand flares, heliograph).

Fire Prevention and Firefighting (STCW A-VI/1-2)

Firefighting knowledge: fire triangle (fuel + oxygen + heat — remove any element to extinguish; classes of fire — Class A solid combustibles; Class B flammable liquids; Class C electrical; Class D metals; shipboard also includes Class F cooking oils), extinguishing agents (CO2 — smothering, for electrical and liquid fires, not for personnel areas without SCBA; dry powder — interrupts chain reaction, for Class B and C; foam — cooling and smothering for Class A and B; water — cooling Class A fires, do not use on electrical; halon and clean agent alternatives — halogenated hydrocarbons for electronics spaces), fixed suppression systems (CO2 flooding systems in engine rooms — pre-discharge alarm requirement, evacuation time, lockout procedures; foam systems in cargo spaces; water mist for accommodation spaces), fire patrol duties (reporting smells, unusual heat, smoke — route and frequency; incipient fire response), and breathing apparatus use (self-contained breathing apparatus SCBA — donning procedure, buddy system, communication in BA team, zero visibility search patterns).

Elementary First Aid and Personal Safety (STCW A-VI/1-3 and A-VI/1-4)

Elementary first aid at sea: CPR (adult one-rescuer CPR — 30 compressions to 2 breaths; compression depth 5-6 cm, rate 100-120/min; AED use — attach pads, analyze, clear, shock if advised; chain of survival on ships), wound treatment (direct pressure for bleeding control — tourniquet as last resort; wound irrigation; impaled object — stabilize, do not remove; burns — cool running water 20 minutes, sterile dressing, do not pop blisters), shock recognition and treatment (position — supine with legs elevated if no head/spinal injury; maintain warmth; oxygen if available; no food or fluids), and hypothermia (maritime survival context — gradual warming, warm dry environment, warm beverages for conscious victim, no rubbing extremities). Personal safety and social responsibilities: safety management system (ISM Code — safety culture, near-miss reporting, SMS documentation), MARPOL environmental responsibilities (Annex I oil pollution — prohibited discharge zones; Annex V garbage — prohibited marine plastics; Annex VI air pollution), and maritime labor rights (MLC 2006 — Manning Convention; right to repatriation; rest hours under STCW — minimum 10 hours rest in any 24-hour period, 77 hours in any 7-day period).
