  1. When a marine technician must enter a double-bottom fuel tank to perform repairs, which document must be issued before entry is permitted?

    Answer: Confined Space Entry Permit / Gas-Free Certificate

    A double-bottom tank is a permit-required confined space; a formal entry permit that includes atmospheric testing results must be completed before entry.

  2. Which personal fall arrest system component directly connects the harness dorsal ring to the anchorage point?

    Answer: Shock-absorbing lanyard or self-retracting lifeline

    The lanyard (or SRL) is the connecting element between the harness D-ring and the anchorage, and it must include an energy absorber to limit arrest forces to 1,800 lbs.

  3. Under 33 CFR Part 155, which vessels are required to have a written Vessel Response Plan (VRP) for oil spill response?

    Answer: Vessels over 400 gross tons that use oil as fuel or carry oil in bulk

    33 CFR 155 requires VRPs for vessels over 400 GRT using oil as fuel or carrying oil in bulk, outlining worst-case discharge response procedures.

  4. A technician is bleeding a diesel fuel system and notices fuel dripping onto the exhaust manifold. The PRIORITY action is to:

    Answer: Shut down the engine immediately and clean up the fuel before continuing work

    Fuel on a hot exhaust manifold is an immediate fire hazard; the engine must be shut down and fuel removed before any further work proceeds.

  5. Which OSHA standard sets the Permissible Exposure Limit (PEL) for carbon monoxide in marine engine repair facilities at 50 ppm as an eight-hour TWA?

    Answer: 29 CFR 1910.1000 (Air Contaminants)

    OSHA's general industry air contaminants standard (29 CFR 1910.1000, Table Z-1) sets a PEL of 50 ppm TWA for carbon monoxide.

  6. A vessel produces used antifreeze (ethylene glycol) during a coolant flush. How must this waste be managed under EPA regulations?

    Answer: Collect and send to a licensed antifreeze recycler or hazardous waste facility

    Used antifreeze may be a hazardous waste if contaminated and must go to a licensed recycler or hazardous waste facility; land or water disposal is prohibited.

  7. Under NFPA 303, what is the required minimum ventilation rate for an enclosed gasoline engine compartment to prevent accumulation of explosive vapors?

    Answer: One cubic foot per minute per cubic foot of net compartment volume

    NFPA 303 requires powered ventilation providing at least 1 CFM per cubic foot of net compartment volume to prevent explosive fuel-air mixtures.
