The correct answers are A, B, and D because leading indicators are designed to provide early warning signals of process safety performance , allowing organizations to act before incidents occur.

Option A is correct because leading metrics help identify weaknesses or degradation in management systems , such as declining inspection completion rates, overdue training, or poor MOC compliance. These indicators reveal problems before they result in incidents.

Option B is also correct because leading indicators support proactive decision-making , enabling organizations to adjust RBPS activities (e.g., maintenance, training, hazard reviews) before a loss of containment or failure event occurs. This is a fundamental goal of process safety management.

Option D is correct because leading metrics can be used to focus and prioritize auditing efforts . For example, areas with declining performance indicators can be targeted for deeper review or corrective actions.

Option C is incorrect because slips, trips, and falls are occupational safety issues , not process safety concerns. Leading process safety metrics are specifically intended to monitor low-frequency, high-consequence risks , not general workplace safety incidents.

CCPS emphasizes that leading indicators are essential for proactive risk management , helping organizations prevent incidents rather than reacting after they occur.
