질문 # 31
A vessel has a rupture disc and pressure relief valve in series to protect against high pressure in the vessel.
There is a pressure gauge on the pipe between the rupture disc and the relief valve. The gauge normally reads zero. As part of regular maintenance inspections, these pressure gauges are supposed to be routinely checked.
Today, a pressure of nearly 50 psig (~3.5 barg) was observed by an operator. There is a significant hazard now. Identify the hazard and discuss which elements of Risk-Based Process Safety could have been involved in the development of this situation.
정답：B
설명：
The correct answer is B because a pressure reading between the rupture disc and relief valve-where it should normally be zero-indicates that the rupture disc has likely failed or is leaking . This creates a serious hazard because the pressure relief valve (PRV) may no longer function as intended , especially if backpressure builds up or if the system configuration compromises its ability to relieve safely. This condition can lead to loss of overpressure protection , increasing the risk of vessel rupture or explosion.
From a CCPS RBPS perspective, several elements are implicated. Mechanical Integrity is central, as the rupture disc may not have been properly inspected, maintained, or replaced. Operating Procedures and Training and Performance Assurance are also relevant, as operators must recognize abnormal readings and respond appropriately. Hazard Identification and Risk Analysis (HIRA) should have considered failure modes such as rupture disc leakage and its impact on relief system performance. Additionally, Management of Change (MOC) could be involved if modifications or replacements were made without proper review.
This scenario highlights how degradation or failure of protective devices, combined with gaps in multiple RBPS elements, can undermine critical safety layers and lead to potentially catastrophic consequences.
질문 # 32
Which of the following criteria would justify not performing a periodic review of operating procedures?
정답：F
설명：
The correct answer is B because periodic review of operating procedures is required as long as the process is active or could be operated , but may not be necessary if the process has been indefinitely suspended or permanently taken out of service .
CCPS emphasizes that operating procedures must be kept current, accurate, and reviewed periodically to ensure safe operation. This requirement applies regardless of automation level, operator experience, or frequency of operation.
Option A is incorrect because even with a strong Management of Change (MOC) system, periodic reviews are still required to ensure procedures remain accurate and complete. MOC addresses changes, but not ongoing validation.
Options C , E , and F are incorrect because automation, infrequent operation, or low turnover do not eliminate the need for review. In fact, infrequent operations may increase risk , making accurate procedures even more critical.
Option D is incorrect because CCPS promotes best practices beyond regulatory minimums ; absence of a regulation does not justify skipping reviews.
Therefore, only when a process is no longer in service (Option B) can periodic procedure review be reasonably deferred, as there is no active operation requiring those procedures.
질문 # 33
The risk of an incident is determined by considering its likelihood and:
정답：B
설명：
The correct answer is A (Consequence) because, according to CCPS Risk-Based Process Safety (RBPS) principles, risk is defined as a function of both likelihood (or frequency) and consequence (severity) . This relationship is fundamental to hazard identification and risk analysis methodologies such as HAZOP, LOPA, and quantitative risk assessment (QRA).
Likelihood represents how often an event may occur, while consequence reflects the potential impact of that event, including effects on people, environment, assets, and business. A high-risk scenario typically involves either a high likelihood, severe consequences, or both.
Option B (Probability) and D (Frequency) are closely related to likelihood and therefore do not complete the definition-they are essentially components of the same side of the risk equation. C (Safeguards) are measures used to reduce either likelihood or consequence but are not part of the definition of risk itself.
CCPS emphasizes that effective risk management requires evaluating both dimensions. For example, even a low-probability event may require strong controls if the consequences are catastrophic. This dual consideration supports prioritization of hazards and the design of appropriate layers of protection to reduce overall risk to tolerable levels.
질문 # 34
Which of the following are appropriate factors to consider when determining the number of individuals on the incident investigation team? (Select all that apply)
정답：A,C
설명：
According to CCPS guidance on Incident Investigation and Learning , the size and composition of an investigation team must be determined based on the nature and complexity of the incident and the need to ensure an objective, competent, and balanced team . Option A is correct because more complex incidents- especially those involving multiple system failures, significant consequences, or unclear causal chains- require a larger team with diverse technical expertise (e.g., operations, engineering, safety).
Option D is also correct because CCPS emphasizes that investigation teams must be free from bias and include members with different perspectives to avoid premature conclusions or blame-focused outcomes. A balanced team improves the quality of root cause analysis and ensures credible findings.
Option B is incorrect because CCPS does not mandate the inclusion of external consultants or insurance agents in every investigation. While external experts may be useful in complex or specialized cases, they are not always required.
Option C is incorrect because team size should not depend on volunteers , but rather on required competencies and investigation scope. Allowing volunteers to determine team size can lead to inefficiency or lack of needed expertise.
Ultimately, CCPS stresses that investigation teams should be fit-for-purpose , technically capable, and structured to produce reliable, learning-focused outcomes.
질문 # 35
A 3000 gallon, stainless steel, insulated vessel rated for 30 psig is equipped with a rupture disc set for 30 psig for emergency relief. Assuming each of the following scenarios has been deemed possible, which would require the smallest sized relief?
정답：A
설명：
The correct answer is A because a pool fire scenario typically results in a slower and more predictable heat input compared to other overpressure scenarios, thus requiring a smaller relief capacity .
In CCPS guidance for relief system design and hazard analysis , different scenarios are evaluated based on how rapidly they generate vapor or pressure. A pool fire heats the vessel externally, causing liquid boiling and vapor generation at a rate governed by heat transfer. Although serious, this is generally a gradual energy input
, allowing for comparatively smaller relief sizing.
Option B (internal ignition) involves rapid combustion of vapor within the vessel, producing a very fast pressure rise , often too fast for conventional relief systems to handle effectively. This would require significantly larger or different protective measures.
Option C (runaway reaction) is the most severe scenario. A reaction with a temperature rise rate of 500°C/min indicates extremely rapid energy release, leading to very high vapor generation rates and pressure rise , requiring the largest relief capacity .
CCPS emphasizes that relief devices must be sized for the worst credible scenario , but when comparing scenarios, external fire cases typically produce the lowest required relief rates , while reactive and explosive scenarios demand much larger capacities.
