The correct answer is A, B, C, and D because all listed items are essential components of an effective process safety audit system , as defined by CCPS within the RBPS framework.
Option A (documenting audit results) is critical because audit findings must be clearly recorded to ensure traceability, accountability, and follow-up of corrective actions . Without proper documentation, lessons learned may be lost and improvements may not be implemented.
Option B (scheduling audits) ensures that audits are conducted at appropriate intervals. CCPS emphasizes that audits should be planned, periodic, and risk-based , rather than ad hoc.
Option C (performing audits) refers to the actual execution of the audit process, including data collection, interviews, field verification, and evaluation of system effectiveness . This is the core activity of the audit system.
Option D (staffing of audit teams) is also essential because audits must be conducted by qualified, competent, and objective personnel . Proper team composition ensures technical expertise, independence, and credibility of findings.
CCPS highlights that a robust audit system includes planning, execution, documentation, and follow-up , all supported by competent personnel to ensure continuous improvement in process safety performance.
