CCPSC Practice Questions

The correct answers are A, B, and C because CCPS defines audits as a critical RBPS activity used to evaluate system performance, ensure effectiveness, and drive continuous improvement .

Option A is correct because audits ultimately aim to reduce process safety risks by identifying weaknesses in management systems before incidents occur. While audits do not directly eliminate hazards, they highlight deficiencies that, when corrected, reduce risk exposure.

Option B is central to the purpose of auditing. CCPS emphasizes that audits are conducted to verify whether Risk-Based Process Safety (RBPS) systems are properly implemented and functioning as intended . This includes checking compliance with internal standards, regulatory requirements, and best practices.

Option C is also correct because audits are a key tool for continuous improvement . They help organizations identify gaps, inefficiencies, and opportunities to strengthen process safety programs.

Option D is incorrect because preparing emergency response plans is part of the Emergency Management element, not an audit objective. Option E is incorrect because audits may review procedures, but they do not “certify” every procedure as correct; rather, they assess whether systems exist to maintain and update them.

Thus, CCPS positions audits as assurance and improvement tools , not execution or certification mechanisms.

The correct answers are B (Hexane), C (Benzene), and D (Toluene) because these are low-conductivity hydrocarbon liquids , which are highly susceptible to static electricity accumulation .

CCPS guidance explains that static charge buildup occurs when fluids flow, splash, or are agitated—especially in non-conductive or poorly conductive liquids . Hydrocarbons such as hexane, benzene, and toluene have low electrical conductivity , meaning that any generated static charge cannot dissipate easily . This can lead to charge accumulation and eventual discharge (spark), which may ignite flammable vapor-air mixtures.

In contrast, sea water (A) is highly conductive due to dissolved salts, allowing static charges to dissipate quickly and preventing dangerous accumulation. Therefore, static electricity is generally not a concern with conductive fluids like seawater.

CCPS emphasizes that static hazards are particularly important during operations such as tank filling, transfer, filtration, and mixing of flammable liquids. Proper controls include bonding and grounding, limiting flow velocities, avoiding splash filling, and using anti-static additives where applicable.

Thus, non-conductive flammable liquids (B, C, D) present a significant static ignition hazard, while conductive liquids like seawater do not.

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.
