ISA CAP Industry Regulations & Compliance 2 — Questions and Answers
Question 1: Which OSHA standard specifically addresses process safety management of highly hazardous chemicals in the US?
- 29 CFR 1910.119 (Correct answer)
- 29 CFR 1910.147
- 29 CFR 1910.269
- 29 CFR 1910.303
Correct answer: 29 CFR 1910.119
OSHA 29 CFR 1910.119 is the Process Safety Management (PSM) standard that applies to facilities handling highly hazardous chemicals above threshold quantities.
Question 2: The EPA's Risk Management Program (RMP) under Section 112(r) of the Clean Air Act requires facilities to submit a Risk Management Plan when they:
- Have more than 50 employees working with chemicals
- Hold threshold quantities of regulated substances (Correct answer)
- Operate 24 hours per day with automated controls
- Use any Class I or Class II flammable material
Correct answer: Hold threshold quantities of regulated substances
The EPA RMP rule requires facilities to develop and submit a Risk Management Plan when they hold regulated substances at or above specified threshold quantities.
Question 3: In the context of functional safety, what does the term 'SIL verification' confirm?
- That the SIS hardware meets physical installation requirements
- That the achieved SIL matches or exceeds the required SIL for the SIF (Correct answer)
- That the safety instrumented system is certified by a third party
- That all sensors have been calibrated to the correct setpoint
Correct answer: That the achieved SIL matches or exceeds the required SIL for the SIF
SIL verification confirms through calculation (e.g., PFD or PFH) that the designed Safety Instrumented Function achieves the required Safety Integrity Level.
Question 4: Under IEC 61511, who bears primary responsibility for defining the Safety Requirements Specification (SRS)?
- The SIS equipment manufacturer
- The automation system integrator
- The process owner or operator (Correct answer)
- The third-party safety auditor
Correct answer: The process owner or operator
IEC 61511 places primary responsibility for the Safety Requirements Specification on the process owner/operator, as they understand the process hazards and risk tolerances.
Question 5: Which regulation requires chemical facilities to perform a Process Hazard Analysis (PHA) and revalidate it every five years?
- EPA 40 CFR Part 68
- OSHA 29 CFR 1910.119 (Correct answer)
- NFPA 72
- ISA-84.00.01
Correct answer: OSHA 29 CFR 1910.119
OSHA PSM (29 CFR 1910.119) requires an initial Process Hazard Analysis and revalidation at least every five years for covered processes.
Question 6: The North American Electric Reliability Corporation (NERC) Critical Infrastructure Protection (CIP) standards primarily govern:
- Chemical plant emergency shutdown systems
- Cybersecurity of bulk electric system assets (Correct answer)
- Nuclear plant radiation monitoring requirements
- Pipeline SCADA communication encryption
Correct answer: Cybersecurity of bulk electric system assets
NERC CIP standards establish cybersecurity requirements specifically for assets that support the reliability of the bulk electric system in North America.
Question 7: Under ISA-62443, a 'Security Level' (SL) target is established by:
- The automation vendor based on product certification
- The asset owner based on risk assessment results (Correct answer)
- The regulatory authority based on industry sector
- The system integrator based on network architecture
Correct answer: The asset owner based on risk assessment results
ISA-62443 requires the asset owner to establish target Security Levels based on their risk assessment, which then drives design and implementation requirements.
