What is the difference between leading and lagging indicators in safety performance?

• A. Leading indicators measure past outcomes; lagging indicators measure safety inputs.
• B. Leading indicators measure safety inputs (training, inspections, near-miss reporting) that influence future performance; lagging indicators measure past outcomes (injury rate, incident counts, days lost).
• C. Leading indicators measure injury severity; lagging indicators measure near-misses.
• D. Leading indicators are financial metrics; lagging indicators are compliance metrics.

Answer: (B)

Leading indicators are proactive measures that track safety inputs and activities that shape future performance, while lagging indicators capture outcomes after events have occurred. This distinction matters because you can influence leading indicators in the present to prevent injuries, whereas lagging indicators show what happened in the past and are harder to reverse. Leading indicators examples include safety training completion, the number of safety inspections conducted, near‑miss reports, and the timely closure of corrective actions. These reflect the actions you take to reduce risk and improve safety going forward. Lagging indicators examples include injury rates, incident counts, and days away from work. These measure the outcomes after incidents have happened and indicate the level of harm that occurred, but they don’t directly drive prevention. So the correct statement aligns with this proactive-vs-outcome framing: safety inputs that influence future performance are leading indicators, while past outcomes like injury rate, incident counts, and days lost are lagging indicators.
