質問 # 57
A principal rule of HAZOP is: "The more participants in the room, the more effective the exercise will be".
True or false?
正解：B
解説：
The correct answer is B (False) because CCPS guidance on HAZOP (Hazard and Operability Study) emphasizes that effectiveness depends on having the right participants, not the maximum number of participants .
A HAZOP team should be multidisciplinary , typically including process engineers, operators, maintenance personnel, control/instrumentation specialists, and a trained facilitator. However, adding too many participants can actually reduce effectiveness by making discussions less focused, harder to manage, and more time-consuming.
CCPS highlights that an optimal team size is usually small enough to be manageable (often 5-8 members) while still providing the necessary expertise. Large groups can lead to issues such as reduced participation, difficulty in reaching consensus, and inefficient use of time.
The key principle is quality over quantity -participants should be selected based on their knowledge, experience, and ability to contribute meaningfully to hazard identification and analysis.
Therefore, the statement is false because simply increasing the number of participants does not improve the quality of the HAZOP. A well-structured, properly facilitated team with the right expertise is far more important for an effective hazard analysis.
質問 # 58
The President of a small chemical company with only one plant states that small companies do not need the same level of Process Safety competency as larger companies. Do you agree or disagree? Explain your answer.
正解：C
解説：
The correct answer is C because CCPS clearly emphasizes that process safety competency requirements are driven by hazard and risk, not organizational size . Even small facilities can handle hazardous chemicals, high pressures, or flammable materials that present significant potential for catastrophic incidents , including fires, explosions, and toxic releases.
The RBPS element Process Safety Competency requires organizations to ensure that personnel possess the appropriate knowledge, skills, and experience to manage process risks effectively. This includes hazard identification, risk assessment, safe operation, and emergency response. These requirements apply equally to small and large organizations when similar hazards exist.
CCPS guidance also highlights that smaller companies may face greater vulnerability due to limited resources, fewer layers of oversight, and less redundancy in expertise. Therefore, maintaining strong competency is even more critical. When internal capability is limited, organizations are expected to use external experts, consultants, or industry resources to fill gaps.
Importantly, many historical incidents have occurred in smaller facilities, reinforcing that risk exposure-not company size-determines the need for robust process safety systems . Thus, all organizations must implement appropriate competency levels proportional to the hazards they manage to ensure safe and reliable operations.
質問 # 59
A pilot operated relief device operates when: (select all that apply)
正解：A、B
解説：
The correct answers are A and D because they describe the fundamental operating principle of a pilot- operated relief valve (PORV) , as recognized in CCPS guidance on pressure relief systems within Mechanical Integrity.
A pilot-operated relief valve uses a pilot (small control valve or regulator) to control the pressure acting on the main valve. Under normal conditions, system pressure is applied to keep the main valve tightly closed. When the system pressure reaches the set pressure , the pilot valve opens, which vents or releases pressure from above (or behind) the main valve seat . This creates a pressure imbalance that allows the main valve to open rapidly-this corresponds directly to D .
Additionally, A is correct because pilot-operated valves are designed to maintain set pressure accuracy even in the presence of backpressure , unlike conventional spring-loaded relief valves, which can be significantly affected by backpressure. This makes PORVs advantageous in systems with variable or high backpressure.
Options B and C are incorrect. Diaphragm rupture is a failure mode, not a normal operating mechanism, and manual opening is not how pilot-operated relief valves function during automatic overpressure protection.
CCPS emphasizes understanding device operating principles to ensure correct application, reliability, and proper maintenance of pressure relief systems.
質問 # 60
Which of the following are Hazard Identification and Risk Analysis methods? (Select all that apply)
正解：A、B、E、F
解説：
The correct answers are B (Layer of Protection Analysis), C (Bow-Tie Analysis), D (What-If), and F (FMEA) because these are recognized Hazard Identification and Risk Analysis (HIRA) methodologies within CCPS Risk-Based Process Safety.
What-If analysis is a qualitative method used to systematically evaluate deviations from intended operation by asking structured "what if" questions. FMEA (Failure Modes and Effects Analysis) is a structured technique that identifies potential failure modes, their causes, and consequences, often used during design and early lifecycle stages.
Layer of Protection Analysis (LOPA) is a semi-quantitative method that evaluates risk by analyzing initiating events and independent protection layers, determining whether risk reduction is sufficient. Bow-Tie analysis visually integrates fault trees (causes) and event trees (consequences), helping to identify preventive and mitigative barriers.
Root Cause Analysis (A) and Fishbone Analysis (E) are not HIRA methods; instead, they are incident investigation tools used after an event to determine underlying causes. CCPS clearly distinguishes between proactive hazard analysis (HIRA) and reactive learning methods (incident investigation and root cause analysis).
These HIRA tools are essential for identifying hazards, evaluating risks, and ensuring appropriate safeguards are in place to prevent major process safety incidents.
質問 # 61
Which of the following are effective methods for verifying that an operator understood the training provided?
(Select all that apply)
正解：A、D
解説：
The correct answers are B and D because CCPS emphasizes that training effectiveness must be verified through demonstrated understanding and competency , not simply attendance or acknowledgment.
Option B is correct because a written quiz or test is a structured method to assess whether the operator has understood key concepts, procedures, and safety requirements. Properly designed tests can validate knowledge retention and comprehension.
Option D is also correct because trainer verification of demonstrated understanding (such as practical demonstrations, simulations, or observed task performance) provides strong evidence that the operator can apply the training in real work situations. This aligns with CCPS expectations for performance-based competency assurance .
Option A is not sufficient because a signed form only confirms that training was completed, not that it was understood. Option C is also inadequate, as attendance does not demonstrate comprehension or ability to perform tasks safely.
CCPS stresses that organizations must ensure personnel are not just trained, but competent to perform safely , which requires verification through testing, observation, and demonstrated performance rather than passive confirmation methods.
