77. Frage
The Accident Pyramid indicates:
Antwort: A
Begründung:
The correct answer is A because the Accident Pyramid (also known as Heinrich's Pyramid or the Safety Triangle) illustrates the relationship between near misses, minor incidents, and major accidents . According to CCPS and traditional safety theory, for every serious or fatal accident, there are many more low-consequence events and near misses that occur but do not result in harm.
This concept is fundamental to process safety metrics and learning systems , as it emphasizes that organizations should not only focus on major incidents but also actively track and investigate near misses and minor events . These lower-level events provide valuable insight into system weaknesses and potential failure pathways before a catastrophic incident occurs.
Option B is incorrect because Murphy's law is unrelated to structured safety analysis. Option C reverses the logic of the pyramid-minor incidents are far more frequent than major ones, not the other way around.
Option D is incorrect because the pyramid represents a range of incident severities , not just major incidents.
CCPS uses this concept to promote proactive safety management , encouraging organizations to learn from small failures and near misses to prevent escalation into severe process safety events.
78. Frage
The photo below represents part of the overhead piping for a reactor with a 90 psig maximum allowable working pressure (MAWP). Which of the following statements are correct? (select all that apply)
Antwort: A,C
Begründung:
The correct answers are B and D because they highlight subtle but critical deficiencies in the pressure relief system configuration , consistent with CCPS guidance.
Option B is correct because the presence of additional components (such as a pressure gauge connection or trapped pressure between the rupture disc and relief valve) can lead to pressure buildup on the downstream side of the rupture disc . This backpressure increases the effective burst pressure , meaning the disc may not rupture at its intended setpoint, thereby compromising overpressure protection.
Option D is also correct because if the rupture disc is intended to protect the relief valve from corrosion , any leakage, improper installation, or pressure buildup in the space between the disc and valve can negate that protection . For example, corrosive process fluid could still reach the relief valve if the disc is not perfectly leak-tight or if the system is not properly maintained.
Option A is incorrect because current operating pressure does not guarantee safety- relief systems must function correctly during upset conditions . Option C is incorrect because placing a rupture disc upstream of a relief valve is an accepted practice when properly designed.
CCPS emphasizes that improper installation details can significantly degrade relief system performance , even when components appear correct.
79. Frage
Which of the following changes require a Management of Organizational Change (MOOC) Review? (Select all that apply.)
Antwort: A,C,E
Begründung:
The correct answers are B, C, and E because these represent organizational changes that can significantly impact process safety risk , and therefore require a Management of Organizational Change (MOOC) review as defined by CCPS under the RBPS framework.
MOOC focuses on evaluating how changes in staffing, structure, roles, responsibilities, or working conditions may affect hazard control, decision-making, supervision, and operational reliability.
B (Replacing maintenance with contractors) introduces risks related to competency, training, communication, and familiarity with site hazards , which are critical CCPS concerns.
C (Reducing number of operators) directly affects workload, fatigue, ability to respond to abnormal situations, and supervision , all of which are key human factor risks.
E (Changing shift length from 8 to 12 hours) impacts fatigue, alertness, and human performance reliability , which CCPS identifies as major contributors to incidents.
The incorrect options are less impactful:
A (moving operator within same unit) does not significantly change organizational risk if competency remains equivalent.
D (office to cubicle relocation) has negligible effect on process safety.
CCPS emphasizes that organizational changes must be treated with the same rigor as technical changes , because many major incidents have been linked to staffing reductions, contractor use, and fatigue-related performance degradation.
80. Frage
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)
Antwort: A,B,C
Begründung:
The correct answers are A (Asset Integrity and Reliability), B (Conduct of Operations), and D (Training and Performance Assurance) because each directly contributed to the failure scenario described.
A (Asset Integrity and Reliability) is implicated because the flow controller was out of calibration , indicating a failure in inspection, testing, or maintenance systems. CCPS emphasizes that instrumentation must be properly maintained and calibrated to ensure reliable process control.
B (Conduct of Operations) is also a key factor. The operator deviated from established procedures by opening a bypass valve. Conduct of Operations requires strict adherence to procedures, proper supervision, and disciplined operational practices to prevent unsafe actions.
D (Training and Performance Assurance) is relevant because the operator either did not understand the risk of bypassing the control system or was not adequately trained to respond appropriately to abnormal situations.
CCPS stresses that personnel must be competent in both normal and upset conditions.
C (Workforce Involvement) is less directly related to the immediate cause, and E (Incident Investigation) applies after an event, not as a causal factor.
This scenario demonstrates how combined weaknesses in equipment reliability, procedural discipline, and operator competence can lead to a major process safety incident such as a runaway reaction.
81. Frage
Which of the following conditions could indicate performance problems in a plant's Asset Integrity program?
(select all that apply)
Antwort: A,B,D
Begründung:
The correct answers are B, C, and D because they represent clear indicators of deficiencies in the Mechanical Integrity (Asset Integrity) program , as defined by CCPS.
Option B is correct because outdated metrics (9 months old) indicate poor performance monitoring and lack of timely oversight . CCPS stresses that asset integrity programs must use current, accurate data to track inspection, testing, and maintenance effectiveness.
Option C is also correct because excessive vibration in rotating equipment is a well-known sign of potential mechanical failure, such as imbalance, misalignment, or bearing issues. This suggests inadequate condition monitoring or maintenance practices.
Option D is critical because piping containing hazardous materials that is not included in inspection programs represents a serious gap. CCPS requires that all critical equipment be identified, risk-ranked, and included in inspection and maintenance plans . Missing such equipment indicates a breakdown in the integrity management system.
Option A reflects good practice, showing operator awareness and effective communication, not a problem.
Overall, CCPS emphasizes that effective asset integrity programs require accurate tracking, proactive monitoring, and comprehensive equipment coverage to prevent loss of containment.
