Read the first 7 Regulatory Compliance and Standards flashcards as text

  1. Which NFPA standard is the primary reference document for controlling gas hazards on vessels and is directly referenced by OSHA's shipyard employment standards?

    Answer: NFPA 306

    NFPA 306, 'Standard for the Control of Gas Hazards on Vessels,' is the primary industry standard for marine chemist operations and is incorporated by reference in OSHA 29 CFR 1915.

  2. Under 46 CFR 35.01-15, a Marine Chemist certificate for hot work on a vessel tank is valid for a maximum of how long before re-inspection is required?

    Answer: 24 hours

    46 CFR 35.01-15 specifies that a hot work certificate is valid for one calendar day (24 hours) and must be renewed by re-inspection if work continues.

  3. A Marine Chemist inspecting a tank that previously carried crude oil finds an LEL reading of 8%. Which certificate designation is correct under NFPA 306?

    Answer: 'Not Safe for Hot Work — Safe for Men'

    At 8% LEL, the space is below the 10% LEL threshold for 'Gas Free' hot work status, so it may be 'Safe for Men' but not 'Safe for Hot Work' under NFPA 306.

  4. Under OSHA 29 CFR 1915.51, respiratory protection requirements for shipyard workers are governed by which additional OSHA standard?

    Answer: 29 CFR 1910.134

    OSHA 29 CFR 1915.51 requires respiratory protection programs to comply with 29 CFR 1910.134, the general industry respiratory protection standard.

  5. Which international convention establishes safety requirements for enclosed spaces aboard ships that marine chemists operating internationally must be aware of?

    Answer: IMO Resolution A.1050(27)

    IMO Resolution A.1050(27), 'Revised Recommendations for Entering Enclosed Spaces Aboard Ships,' provides international guidance aligned with marine chemist practice.

  6. Under NFPA 306, the term 'Inert' as a space designation means the atmosphere has been purged with an inert gas and the oxygen content is below what level?

    Answer: 8%

    NFPA 306 defines an 'Inert' space as one where oxygen has been displaced to below 8% to prevent flammable mixture formation, making the space safe from explosion but not for entry.

  7. Which OSHA standard governs permit-required confined space entry in general industry, and how does it differ from 29 CFR 1915 for shipyard workers?

    Answer: 1910.146 applies to general industry; 1915 applies to shipyards and has additional marine-specific atmospheric testing protocols

    OSHA 1910.146 covers general industry confined spaces while 29 CFR 1915 Subpart B provides shipyard-specific atmospheric testing and marine chemist requirements.
