質問 # 16
Leading process safety metrics can help: (select all that apply)
正解：B、C、D
解説：
The correct answers are A, B, and D because leading indicators are designed to provide early warning signals of process safety performance , allowing organizations to act before incidents occur.
Option A is correct because leading metrics help identify weaknesses or degradation in management systems , such as declining inspection completion rates, overdue training, or poor MOC compliance. These indicators reveal problems before they result in incidents.
Option B is also correct because leading indicators support proactive decision-making , enabling organizations to adjust RBPS activities (e.g., maintenance, training, hazard reviews) before a loss of containment or failure event occurs. This is a fundamental goal of process safety management.
Option D is correct because leading metrics can be used to focus and prioritize auditing efforts . For example, areas with declining performance indicators can be targeted for deeper review or corrective actions.
Option C is incorrect because slips, trips, and falls are occupational safety issues , not process safety concerns.
Leading process safety metrics are specifically intended to monitor low-frequency, high-consequence risks , not general workplace safety incidents.
CCPS emphasizes that leading indicators are essential for proactive risk management , helping organizations prevent incidents rather than reacting after they occur.
質問 # 17
Sources of information on previous incidents to be reviewed during a Process Hazard Analysis can include:
(select all that apply)
正解：A、B、C、D
解説：
The correct answer is A, B, C, and D because CCPS emphasizes that Process Hazard Analysis (PHA) should incorporate comprehensive incident history data from multiple relevant sources to ensure thorough hazard identification and risk evaluation.
Option A (site operating experience) is critical because it provides direct, first-hand knowledge of past incidents, near misses, and abnormal situations specific to the process being analyzed.
Option B (other locations within the company) is equally important because similar processes at different sites may have experienced incidents that reveal hazards not yet encountered locally. CCPS strongly encourages sharing lessons learned across sites .
Option C (publicly available sources) includes databases from industry groups, regulatory bodies, and technical organizations. These sources provide broad industry experience , helping identify rare but high- consequence scenarios.
Option D (site safety department) is also valid because safety teams often maintain incident records, investigation reports, and lessons learned , making them a key internal resource.
CCPS stresses that effective PHA depends on leveraging both internal and external knowledge to avoid overlooking hazards. Using diverse information sources improves the ability to identify credible scenarios and implement appropriate safeguards.
質問 # 18
Management of Change review should be done: (select all that apply)
正解：B、C
解説：
The correct answers are A and B because CCPS defines Management of Change (MOC) as a systematic process applied to all process-related changes across the lifecycle of a facility .
Option A is correct because MOC is specifically required for process-related changes , including modifications to equipment, chemicals, technology, procedures, and operating conditions. These changes can introduce new hazards or alter existing risks, making formal review essential.
Option B is also correct because MOC applies throughout the entire process lifecycle , including design, construction, operation, maintenance, and decommissioning. CCPS emphasizes that changes can occur at any stage, and each must be evaluated for safety impact.
Option C (replacement in kind) is incorrect because true replacement in kind-where there is no change in specifications or function -does not require MOC. However, careful verification is needed to confirm it is truly identical.
Option D is incorrect because confirming operational readiness is part of Pre-Startup Safety Review (PSSR) , not MOC itself. Option E relates to auditing or compliance activities , not the purpose of MOC.
CCPS highlights that effective MOC ensures all changes are reviewed, authorized, and safely implemented , preventing unintended consequences.
質問 # 19
A process calls for the addition of a reactant over a certain period of time. The flow controller on the reactant' s feed line was out of calibration and reduced the flow rate of the reactant. The operator noticed the addition rate was too low and, contrary to the operating procedures, he opened a bypass valve around the flow control valve to increase the flow rate. As a result, the operator added the remaining reactant too quickly, and a runaway reaction occurred. Weaknesses in which of the following Risk Based Process Safety elements could have contributed to the cause of this incident? (Select all that apply)
正解：A、C、D
質問 # 20
A facility is selecting an inerting procedure for one of its large reactors. Which inerting method would be expected to require the greatest nitrogen consumption?
正解：B
解説：
The correct answer is C (Sweep through purging) because it is the least efficient inerting method in terms of inert gas consumption , as described in CCPS guidance on inerting and purging practices.
In sweep through purging , nitrogen is continuously introduced into the vessel while the existing gas mixture is displaced and vented. This method relies on dilution rather than compression or evacuation, meaning that large volumes of nitrogen are required to achieve the desired reduction in oxygen concentration. The inefficiency arises because complete mixing is assumed, and multiple vessel volume exchanges are needed.
In contrast, pressure purging (B) and vacuum purging (A) are significantly more efficient. Pressure purging uses repeated pressurization and venting cycles to reduce oxygen concentration, while vacuum purging removes gases before backfilling with nitrogen. The most efficient method is typically combined vacuum
/pressure purging (D) , which minimizes nitrogen usage by leveraging both techniques.
Siphon purging (E) is not a commonly recognized CCPS inerting method for gas-phase systems.
CCPS emphasizes selecting inerting methods based on vessel design, pressure capability, safety requirements, and gas consumption efficiency. For large vessels, minimizing nitrogen usage is often important for both cost and operational practicality.
