- 1 year
Correct answer: 5 years
33 CFR 155.1060 requires vessel response plans to be submitted to USCG for review at least every five years.
Question 2: Which international convention governs the prevention of pollution from ships by noxious liquid substances in bulk?
- SOLAS Chapter XII

- Issue a conditional entry permit with respirator requirements
- Certify 'Not Safe' and notify the person in charge (Correct answer)
- Recommend additional ventilation and retest in one hour
- Allow entry only for sampling purposes
Correct answer: Certify 'Not Safe' and notify the person in charge
When hazardous atmospheres exceed regulatory limits, the Marine Chemist must certify the space as 'Not Safe' and inform the responsible party.
Question 4: The IBC Code (International Bulk Chemical Code) applies to vessels built after:
- July 1, 1983 (Correct answer)
- January 1, 1986
- July 1, 1986
- January 1, 1983
Correct answer: July 1, 1983
The IBC Code applies to chemical tankers constructed on or after July 1, 1986, while the BCH Code covers vessels built before that date.
Question 5: Under EPA regulations (40 CFR Part 112), facilities handling oil above threshold quantities must prepare a:
- Hazardous Waste Contingency Plan
- Spill Prevention Control and Countermeasure (SPCC) Plan (Correct answer)
- Risk Management Plan (RMP)
- Stormwater Pollution Prevention Plan (SWPPP)
Correct answer: Spill Prevention Control and Countermeasure (SPCC) Plan
40 CFR Part 112 requires facilities with oil storage above threshold quantities that could reasonably discharge to navigable waters to prepare an SPCC Plan.
Question 6: Which USCG regulation establishes requirements for the handling of hazardous materials in port areas and waterfront facilities?
- 33 CFR Part 154
- 46 CFR Part 98

33 CFR Part 126 governs the handling of dangerous cargo at waterfront facilities, including permits, safety requirements, and facility standards.
Question 7: When testing a space that previously contained crude oil, a Marine Chemist detects H₂S at 18 ppm. Per NFPA 306, this space should be certified as:
- Safe for Workers with appropriate PPE noted
- Safe for Hot Work only
- Not Safe (Correct answer)
- Safe for Workers — H₂S is below IDLH
Correct answer: Not Safe
NFPA 306 requires that H₂S not exceed 10 ppm (OSHA ceiling) for a Safe for Workers certificate; 18 ppm requires a 'Not Safe' designation.
