What is the role of process safety metrics in reactivity hazards?

• A. Track indicators such as incident rates, near-misses, audit findings, and effectiveness of safeguards to drive improvement.
• B. Daily production yields and energy consumption.
• C. Equipment maintenance intervals only.
• D. Employee training hours alone.

Answer: (A)

Process safety metrics measure how well a facility controls reactive hazards by tracking safety performance indicators such as incident rates, near-misses, audit findings, and the effectiveness of safeguards. These metrics create a feedback loop that helps identify trends, confirm whether safeguards are actually working, and reveal gaps in procedures, engineering controls, or management oversight. By monitoring these indicators, teams can prioritize corrective actions, update operating procedures, strengthen safeguards, and allocate resources to prevent dangerous reactivity events. Metrics focused on production yield or general energy use don’t directly reflect how well reactive hazards are being managed, and maintenance intervals or training hours alone don’t show the effectiveness of safety protections.
