Read the first 7 Maritime Safety Regulations & Compliance flashcards as text

  1. Under 33 CFR 153.203, the owner or operator of a vessel that discharges oil into US navigable waters must report the spill to the National Response Center within:

    Answer: As soon as possible

    33 CFR 153.203 requires immediate notification to the NRC upon discovery of a reportable discharge — 'as soon as possible' with no specific delay permitted.

  2. A Marine Chemist testing a ballast tank aboard a vessel finds that all atmospheric readings are within safe limits but visibility is severely restricted by vapor. What certificate should be issued?

    Answer: Safe for Workers with visibility warning noted

    Atmospheric safety and physical hazards are separate considerations; if all gas readings are safe, Safe for Workers can be issued with notation of the visibility hazard.

  3. Which international code establishes minimum safety standards for the bulk transport of liquefied gases by sea?

    Answer: IGC Code

    The International Gas Carrier (IGC) Code establishes standards for ships carrying liquefied gases in bulk, covering design, construction, and equipment.

  4. Under the Clean Water Act Section 311, a 'harmful quantity' of oil discharged into US waters is defined as any amount that:

    Answer: Causes a visible sheen on the water surface

    The CWA Section 311 and implementing regulations define a harmful quantity of oil as that which causes a sheen, discoloration, or sludge on water.

  5. Before a Marine Chemist may certify a tank as 'Safe for Hot Work,' which sequence of actions is required?

    Answer: Atmospheric testing, followed by inspection of adjacent spaces

    NFPA 306 requires the Marine Chemist to test the primary space and all adjacent spaces before issuing a Safe for Hot Work certificate.

  6. Which USCG regulation requires chemical tankers operating in US waters to carry a Cargo Information Card for each hazardous cargo?

    Answer: 46 CFR Part 153

    46 CFR Part 153 requires that vessels carrying bulk liquid hazardous materials maintain Cargo Information Cards with emergency response data for each cargo.

  7. Under NFPA 306, which measurement instrument technique is most appropriate for detecting oxygen-depleted atmospheres in a deep tank before entry?

    Answer: Direct-reading electrochemical sensor on a probe extension

    An electrochemical oxygen sensor on an extension probe allows sampling of atmosphere at various depths without requiring personnel entry before conditions are confirmed safe.
