SPED Codes, Regulations & Safety Practices 2 — Questions and Answers
Question 1: Which ASME code governs the design and fabrication of pressure vessels used in the chemical and petroleum industries?
- ASME B31.3
- ASME B31.1
- ASME Section VIII Division 1 (Correct answer)
- ASME Section IX
Correct answer: ASME Section VIII Division 1
ASME Boiler and Pressure Vessel Code Section VIII Division 1 governs pressure vessels used in chemical and petroleum processing applications.
Question 2: Under OSHA's Process Safety Management (PSM) standard 29 CFR 1910.119, what is the threshold quantity of chlorine that triggers PSM requirements?
- 1,500 lbs (Correct answer)
- 2,500 lbs
- 10,000 lbs
- 500 lbs
Correct answer: 1,500 lbs
OSHA PSM lists chlorine with a threshold quantity of 1,500 lbs, above which facilities must comply with 29 CFR 1910.119.
Question 3: ASME B31.3 Process Piping requires a minimum hydrostatic leak test pressure equal to how many times the design pressure?
- 1.25 times
- 1.5 times (Correct answer)
- 2.0 times
- 1.1 times
Correct answer: 1.5 times
ASME B31.3 requires hydrostatic leak test pressure to be at least 1.5 times the design pressure.
Question 4: Which regulatory body enforces the National Emission Standards for Hazardous Air Pollutants (NESHAP) applicable to piping equipment leaks?
- OSHA
- EPA (Correct answer)
- DOT
- PHMSA
Correct answer: EPA
The EPA enforces NESHAP regulations under the Clean Air Act, including equipment leak standards for chemical process piping.
Question 5: In ASME B31.1 Power Piping, Category D fluid service is defined as a non-flammable, non-toxic fluid at what maximum temperature and gauge pressure?
- 300°F and 150 psig (Correct answer)
- 250°F and 100 psig
- 150°F and 75 psig
- 400°F and 200 psig
Correct answer: 300°F and 150 psig
ASME B31.1 Category D fluid service is defined as non-flammable, non-toxic fluid at temperatures not exceeding 300°F and gauge pressures not exceeding 150 psig.
Question 6: The API 570 standard applies to the inspection, repair, alteration, and rerating of which type of piping systems?
- New construction process piping
- In-service petroleum refinery piping (Correct answer)
- Natural gas transmission lines
- Nuclear power plant piping
Correct answer: In-service petroleum refinery piping
API 570 covers inspection, repair, alteration, and rerating of in-service piping systems used in petroleum refinery and chemical plant operations.
Question 7: Which document establishes the minimum safety requirements for the operation of natural gas distribution pipelines in the United States?
- 49 CFR Part 192 (Correct answer)
- ASME B31.8
- API RP 1110
- NFPA 54
Correct answer: 49 CFR Part 192
49 CFR Part 192 is the federal regulation that establishes minimum safety standards for the transportation of natural and other gas by pipeline.
