The correct answers are A and B , as they align with CCPS guidance on the Process Safety Auditing element within RBPS.
A is correct because CCPS defines an audit as a systematic and independent evaluation used to verify whether process safety systems comply with internal standards, external regulations, and recognized good engineering practices (RAGAGEP) . Independence is critical to ensure objectivity and credibility of the audit findings.
B is also correct because CCPS allows and encourages the inclusion of facility representatives during second- and third-party audits . These individuals provide essential operational knowledge, clarify site-specific practices, and facilitate access to documents and personnel. However, they do not compromise independence as long as they do not control the audit outcome.
C is incorrect because findings and recommendations are distinct . Findings identify gaps or non-conformances, while recommendations propose corrective actions.
D is incorrect because audits staffed only with site personnel lack independence and may introduce bias. CCPS stresses the importance of independent or external auditors , especially for higher-level or corporate audits.
Overall, effective audits are structured, objective, and supported by knowledgeable personnel while maintaining independence to ensure accurate evaluation of process safety performance.
