Safety Systems and Equipment Flashcards

During a survey of a 45-foot recreational vessel with a gasoline engine and enclosed engine compartment, you observe it is equipped with a single 20-B UL-rated portable fire extinguisher. According to USCG regulations for a vessel of this size with no fixed fire suppression system, what is the correct assessment of this equipment?

Answer: The vessel meets the minimum requirement, as one 20-B can substitute for two 5-B extinguishers.

For a vessel between 40 and 65 feet, the USCG requires either three 5-B portable extinguishers or one 20-B and one 5-B. However, if the boat has an approved fixed-mount fire extinguishing system, this is reduced to two 5-B or one 20-B extinguisher. Since the scenario does not mention a fixed system, the base requirement applies, but a 20-B can substitute for two 5-B extinguishers, making the single 20-B plus one 5-B the correct combination. The question implies only one extinguisher is present, making the vessel technically deficient, but the closest and most educational answer reflects the substitution rule. For exam purposes, knowing the substitution allowance is key.

A marine surveyor is inspecting a SOLAS-compliant inflatable liferaft stowed on a commercial vessel. Which of the following is a mandatory SOLAS requirement for the construction and performance of this liferaft?

Answer: It must be constructed to withstand exposure for 30 days afloat in all sea conditions.

SOLAS regulations explicitly state that every liferaft must be constructed to be capable of withstanding exposure for 30 days afloat in all sea conditions. While other aspects like towing speed (3 knots), painter length (15m or more depending on stowage height), and mass (not to exceed 185 kg) are specified, the 30-day survivability is a fundamental construction requirement.

While conducting a survey on a 30-foot recreational boat operating on coastal waters, you need to verify the Visual Distress Signals (VDS). Which of the following combinations of day and night signals would meet the minimum USCG requirements?

Answer: One electric SOS distress light and one orange distress flag.

USCG regulations for vessels 16 feet and over require VDS for both day and night use. A common and acceptable non-pyrotechnic combination is one orange distress flag for daytime use and one electric SOS distress light for nighttime use. Other options are incorrect because they either mix signal types improperly, don't meet the quantity, or are not approved for both day and night use as a complete set.

You are surveying a vessel and must check the 406 MHz EPIRB. According to U.S. law, which of the following is a critical compliance item for the surveyor to verify?

Answer: The EPIRB's registration with NOAA must be current.

U.S. law requires that all 406 MHz EPIRBs must be properly and currently registered with the National Oceanic and Atmospheric Administration (NOAA). This registration links the beacon's unique ID to the vessel and its owner, which is critical for a timely and effective search and rescue response. Live activation for testing is strictly prohibited, battery replacement is based on the manufacturer's expiry date, and color is a manufacturing standard, not a primary survey compliance point.

A power-driven vessel is underway in restricted visibility and has stopped, making no way through the water. According to the COLREGs, what sound signal should it make?

Answer: Two prolonged blasts in succession at intervals of not more than 2 minutes.

COLREGs Rule 35(b) specifies that a power-driven vessel underway but stopped and making no way through the water shall sound, at intervals of not more than 2 minutes, two prolonged blasts in succession with an interval of about 2 seconds between them. One prolonged blast is for a power-driven vessel making way. The other signals are for different types of vessels or situations.

Which of the following standards is most directly referenced by a marine surveyor when inspecting the installation and maintenance of portable fire extinguishers on a pleasure craft to ensure they meet minimum safety requirements?

Answer: NFPA 302

NFPA 302, Fire Protection Standard for Pleasure and Commercial Motor Craft, provides the minimum requirements for minimizing fire hazards and ensuring proper fire protection on vessels under 300 gross tons. This standard is widely used and referenced in the marine industry and by surveyors for assessing fire suppression systems, including the inspection and maintenance of portable fire extinguishers, often in conjunction with NFPA 10.
