CPA Safety Standards & Regulations 3 — Questions and Answers
Question 1: Which hazard communication standard requires Safety Data Sheets (SDS) to follow a standardized 16-section format?
- OSHA HazCom 2012 (GHS-aligned) (Correct answer)
- NFPA 704 Standard
- EPA EPCRA Title III
- DOT HM-181
Correct answer: OSHA HazCom 2012 (GHS-aligned)
OSHA's HazCom 2012 standard aligned US requirements with the Globally Harmonized System, mandating the 16-section SDS format for all hazardous chemicals.
Question 2: A 'hot work permit' is required before performing which activity in a petroleum facility?
- Inspecting storage tank exteriors
- Welding near flammable vapor sources (Correct answer)
- Taking inventory readings with a gauge tape
- Filling out a JSA (Job Safety Analysis)
Correct answer: Welding near flammable vapor sources
Hot work permits are mandatory before any spark- or heat-producing activity like welding near sources of flammable vapors to prevent ignition.
Question 3: Under DOT regulations, the four-digit identification number on a hazmat placard refers to the:
- UN/NA identification number for the specific material (Correct answer)
- Flashpoint temperature in Fahrenheit
- Emergency response guidebook page number
- Tank capacity in gallons
Correct answer: UN/NA identification number for the specific material
The four-digit UN/NA number on a hazmat placard identifies the specific hazardous material and links to emergency response information.
Question 4: What is the purpose of an atmospheric monitoring program in confined space entry at petroleum facilities?
- To measure ambient temperature for worker comfort
- To test for oxygen deficiency, flammable vapors, and toxic gases before entry (Correct answer)
- To ensure noise levels comply with OSHA standards
- To verify that lighting levels are adequate for work
Correct answer: To test for oxygen deficiency, flammable vapors, and toxic gases before entry
Atmospheric monitoring tests confined spaces for oxygen levels (19.5-23.5%), flammable vapor concentrations below 10% LEL, and toxic gas levels before workers enter.
Question 5: Which type of fire extinguisher is recommended for Class B fires involving flammable liquids such as gasoline?
- Class A water extinguisher
- Class B CO2 or dry chemical extinguisher (Correct answer)
- Class C halon extinguisher
- Class D dry sand extinguisher
Correct answer: Class B CO2 or dry chemical extinguisher
Class B fires involving flammable liquids are best suppressed with CO2 or dry chemical extinguishers that smother the fire without spreading the liquid.
Question 6: The OSHA general duty clause (Section 5(a)(1)) requires employers to:
- Provide free PPE to all employees regardless of hazard level
- Furnish a workplace free from recognized hazards likely to cause death or serious harm (Correct answer)
- Conduct annual safety audits by third-party inspectors
- Post OSHA 300 logs in all work areas year-round
Correct answer: Furnish a workplace free from recognized hazards likely to cause death or serious harm
Section 5(a)(1) of the OSH Act requires employers to provide a workplace free from recognized hazards even when no specific OSHA standard applies.
Question 7: Pipeline facilities must conduct which type of inspection to comply with API 570 for in-service piping systems?
- Annual hydrostatic pressure testing
- Periodic thickness measurement and visual inspection (Correct answer)
- Daily ultrasonic full-line scanning
- Monthly cathodic protection surveys
Correct answer: Periodic thickness measurement and visual inspection
API 570 requires periodic inspection of in-service piping including thickness measurements to track corrosion rates and visual inspection for external damage.
