質問 # 13
A rupture pin relief device operates when:
正解：A
解説：
The correct answer is C because a rupture pin relief device operates based on the mechanical buckling of a calibrated pin (or rod) at a predetermined pressure.
According to CCPS and industry practice, rupture pin devices are a type of non-reclosing pressure relief device that rely on structural instability (buckling) rather than spring force or membrane rupture. The pin is designed to fail (buckle) at a specific load corresponding to a set pressure. When this occurs, the valve mechanism is released, allowing the system to relieve pressure.
This design provides high accuracy and reliability , especially in applications where precise set pressure is required and where traditional spring-loaded relief valves may be affected by corrosion, vibration, or backpressure.
Option A is incorrect because it describes a spring-loaded relief valve , not a rupture pin device. Option B is incorrect because rupture pin devices are mechanical, not electrically actuated . Option D is incorrect because there is no such concept as a "pin seat" type of relief valve.
CCPS highlights rupture pin devices as an alternative to rupture discs and spring valves, particularly where tight tolerances and resistance to process conditions are needed.
質問 # 14
A Management of Change system should address all types of changes to the process that can be reasonably foreseen.
正解：A
解説：
The correct answer is A (True) because CCPS Risk-Based Process Safety clearly states that a Management of Change (MOC) system must address all types of changes that could impact process safety and can be reasonably anticipated .
These changes include modifications to process technology, equipment, procedures, chemicals, operating conditions, and organizational structure . CCPS emphasizes that even seemingly minor changes can introduce new hazards or alter existing risk profiles, making it essential that they are systematically identified and evaluated.
The phrase "reasonably foreseen" is important. It acknowledges that while not every possible scenario can be predicted, organizations are expected to anticipate typical and credible changes based on experience, design knowledge, and operational practices. This includes both permanent and temporary changes, as well as emergency changes (which may follow an expedited but still controlled process).
A robust MOC system ensures that hazards are assessed, safeguards are reviewed, documentation is updated, and personnel are trained before implementation. Failure to capture foreseeable changes is a common root cause of major process safety incidents.
Therefore, CCPS considers it essential that MOC systems are comprehensive in scope , covering all foreseeable changes to maintain process safety and operational integrity.
質問 # 15
The following groups may provide information required for the Process Knowledge Management element (select all that apply)
正解：A、C、D
解説：
The correct answers are A, B, and C because Process Knowledge Management (PKM) requires collecting and maintaining accurate technical information from all relevant and credible sources involved in process design, operation, and development.
Process equipment vendors (A) are a key source of detailed equipment design data, operating limits, materials of construction, and performance specifications. This information is essential for safe operation and maintenance.
External engineering firms (B) contribute critical knowledge related to process design, system integration, hazard considerations, and technical calculations. They often develop PFDs, P & IDs, and design basis documents, all of which are core PKM components.
Corporate research and development (C) provides essential data on chemical properties, reaction kinetics, hazards, and scale-up considerations. This information is particularly important for understanding process chemistry and potential risks.
Option D (Local emergency responders) is incorrect because, while they play an important role in Emergency Management , they are not a primary source of process knowledge such as chemical, design, or engineering data required under PKM.
CCPS emphasizes that PKM must integrate information from multiple technical sources to ensure completeness, accuracy, and accessibility, forming the foundation for hazard analysis, safe operations, and risk management.
質問 # 16
Lagging indicators include: (select all that apply)
正解：B、E
解説：
The correct answers are C and D because lagging indicators measure events that have already occurred , particularly those involving loss of containment or failures with consequences.
Option C (hazardous material releases) is a classic lagging indicator. It reflects an actual failure of containment and is a key metric used in process safety performance (e.g., Tier 1 and Tier 2 events per CCPS
/ANSI/API RP 754).
Option D (spills inside secondary containment) is also a lagging indicator. Although the spill may be contained and less severe, it still represents a loss of primary containment , meaning an incident has already occurred.
Option A (management system failures) and E (missed inspections) are leading indicators because they identify weaknesses in systems before incidents occur . Option B (interlock activations) is generally considered a leading or near-miss indicator , signaling that safeguards are being challenged but have not yet failed.
CCPS emphasizes that lagging indicators are important for tracking outcomes and learning from failures , while leading indicators are used to proactively prevent incidents . A strong process safety program uses both types to ensure continuous improvement and risk reduction.
質問 # 17
Which of the following statements apply to the purpose of an incident investigation? (Select all that apply)
正解：B、C
解説：
The correct answers are A and C because CCPS defines the primary purpose of incident investigation as learning and prevention , not blame or administrative classification.
A (continuous improvement) is a core objective. CCPS emphasizes that incident investigations should identify system weaknesses, gaps in safeguards, and management system deficiencies. The findings are used to strengthen process safety programs, improve procedures, enhance training, and refine risk controls.
C (prevent recurrence) is the fundamental goal. Investigations focus on identifying root causes and contributing factors to ensure that similar incidents do not happen again. This includes both immediate causes and deeper organizational or systemic issues.
Option B is incorrect because CCPS promotes a no-blame or just culture approach . The focus is not on assigning fault or discipline but on understanding why defenses failed. Blame-oriented investigations discourage reporting and hinder learning.
Option D is also incorrect because not all injuries are classified as process safety incidents . CCPS distinguishes between occupational safety (e.g., slips, trips) and process safety events (loss of containment of hazardous materials). The purpose of investigation is not merely documentation but learning and prevention.
Overall, incident investigation is a critical feedback loop in RBPS for continuous risk reduction and organizational learning.
