質問 # 57
A facility's process safety staff does consequence modeling for releases of various toxic substances that the facility handles. Which elements of Risk Based Process Safety would be most likely to use the results of this modeling? (Select all that apply)
正解：B、C、D
解説：
The correct answers are C (Stakeholder Outreach), D (Hazard Identification and Risk Analysis), and E (Emergency Management) because consequence modeling is fundamentally used to understand the potential impact of hazardous material releases and to support risk-informed decision-making across these RBPS elements.
Within Hazard Identification and Risk Analysis (HIRA) , consequence modeling is a core analytical tool used in studies such as HAZOP, LOPA, and quantitative risk assessments (QRA). It helps estimate the severity of potential release scenarios, including toxic dispersion, which directly supports risk evaluation and safeguards selection.
For Emergency Management , modeling results are essential to plan effective response strategies. They define hazard zones, evacuation distances, shelter-in-place decisions, and emergency resource allocation. CCPS emphasizes that credible worst-case and alternative release scenarios should guide emergency preparedness planning.
In Stakeholder Outreach , consequence modeling provides critical information for communicating risks to external parties such as local communities, regulators, and emergency responders. This aligns with CCPS guidance on transparency and community awareness, ensuring stakeholders understand potential offsite consequences.
Operational Readiness (A) focuses on startup and system preparedness, not consequence modeling outputs.
Measurement and Metrics (B) deals with performance indicators rather than predictive hazard analysis.
Therefore, they are less directly connected to the use of consequence modeling results.

Which of the following factors affect the ability of a Safety Relief Valve to provide the required overpressure protection on a vessel? (Select all that apply)
正解：A、B、C
解説：
The correct answers are B, D, and E because these factors directly influence the performance, reliability, and capacity of a Safety Relief Valve (SRV), as emphasized in CCPS Mechanical Integrity and pressure relief system design guidance.
B (inlet and outlet piping design) is critical. Improper inlet piping can cause excessive pressure drop, leading to valve instability or chatter, while poorly designed discharge piping can create backpressure that reduces relieving capacity. CCPS stresses that piping design must meet strict criteria to ensure the valve functions as intended.
D (material of construction) affects the valve's ability to withstand process conditions such as corrosion, temperature, and chemical compatibility. Incorrect materials can lead to sticking, leakage, or failure to open at the set pressure.
E (boiling point and temperature of contents) are essential for determining the relieving scenario and required capacity . These properties influence whether the relief is vapor, liquid, or two-phase flow, which directly affects sizing and performance.
Option A (toxicity) does not affect the mechanical ability of the valve to relieve pressure-it is relevant for consequence analysis, not valve function. C (wind conditions) impacts dispersion after discharge, not the valve's ability to provide overpressure protection.
CCPS highlights that proper design, installation, and material selection are crucial to ensure reliable pressure relief performance.
質問 # 59
A pilot operated relief device operates when: (select all that apply)
正解：B、C
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 is generally a disadvantage of a rupture disc vs a relief valve?
正解：B
解説：
The correct answer is C because rupture discs are generally more fragile and susceptible to damage during installation and handling compared to relief valves, which is a recognized disadvantage in CCPS guidance on pressure relief systems within Mechanical Integrity.
Rupture discs are thin membranes designed to burst at a specific pressure. Because of their delicate construction, improper installation (e.g., incorrect torque, misalignment, or physical handling damage) can alter their burst pressure or cause premature failure. This sensitivity requires strict installation procedures, trained personnel, and careful inspection practices.
Option A is actually an advantage of rupture discs. They provide tight sealing with zero leakage , preventing fugitive emissions and eliminating simmering that can occur in relief valves.
Option B is also an advantage. Rupture discs respond very rapidly to sudden pressure spikes , making them suitable for scenarios like deflagrations or tube ruptures.
Option D is generally considered an advantage as well, since rupture discs can be made from corrosion- resistant materials or coated, often at lower cost than equivalent corrosion-resistant relief valves.
CCPS emphasizes selecting pressure relief devices based on service conditions, reliability, response characteristics, and maintenance considerations, including installation sensitivity.
質問 # 61
A field operator contacted the control room about a leaking connection on a heat exchanger. The control room operator instructed the field operator to bypass the heat exchanger. However, unknown to the control room operator, additional piping had recently been installed upstream of the heat exchanger, and had not been recorded on the P & ID. When the field operator incorrectly opened a valve in the new piping, the process stream was routed to an unintended location.
Which of the following groups of Risk Based Process Safety elements, if properly implemented, could have prevented this incident?
正解：A
解説：
The best answer is C because the scenario shows three clear failures that align directly with these RBPS elements. First, the new upstream piping was not recorded on the P & ID , which is a failure of Process Knowledge Management (PKM) . CCPS identifies PKM as the element for developing, documenting, and maintaining accurate process safety information such as drawings and system knowledge. Second, the piping had been recently installed , so the change should have been formally reviewed, approved, documented, and communicated through Management of Change (MOC) . CCPS describes MOC as the system for recognizing changes, evaluating their hazards, authorizing them, and ensuring follow-up actions are completed. Third, the field operator incorrectly opened a valve , which points to inadequate Training and Performance Assurance -operators must be trained and shown capable of performing tasks correctly, especially when systems have changed.
The other options are weaker because Emergency Management is mainly for response, not prevention; Asset Integrity concerns equipment fitness and reliability, not undocumented configuration changes; and Safe Work Practices , while important, do not address the central failure as directly as PKM, MOC, and Training.
