A leading indicator is a proactive safety measure that tracks the activities and conditions that help prevent injuries before they occur.
A leading indicator is a proactive safety measure that tracks the activities, behaviors and conditions that help prevent injuries and incidents before they happen. Examples include the number of hazards reported and fixed, inspections completed, safety training delivered and near misses reported.
Where lagging indicators count harm after it occurs, leading indicators give early warning. They show whether the parts of a safety program that should prevent incidents are actually working, and they let teams act while there is still time to stop an injury.
OSHA, the National Safety Council and many industry groups encourage employers to use leading indicators alongside traditional injury rates. A good set of leading indicators is specific to the organization's real risks, easy to collect and clearly linked to actions that reduce those risks.
Start with the hazards most likely to cause serious harm in your operations and choose indicators that show whether controls for those hazards are in place. A count of meetings held says little on its own. A measure such as the percentage of fall protection inspections passed says much more.
If teams are rewarded only for higher numbers, they may submit low-value reports to hit targets. Review the quality of observations and inspections, and pair activity counts with outcome-focused measures such as hazards actually removed.
Leading indicators are useful only if someone reviews them and acts. Share results in regular meetings, look for trends by site or crew, and follow up when numbers drop. Combine them with lagging measures in a balanced set of key performance indicators (KPIs).
A logistics company with several distribution centers had low injury rates but a recent forklift collision that nearly struck a pedestrian. The safety manager introduced three leading indicators at every site: daily forklift pre-use checks completed, pedestrian and forklift near misses reported, and the time to fix reported traffic hazards.
Within two months, one site showed far fewer pre-use checks and almost no near miss reports. A visit found that night-shift supervisors were not collecting checklists and workers did not know how to report near misses. After retraining and adding a simple mobile reporting form, the site's numbers matched the others and several aisle layout hazards were fixed.
Common examples include the number of near misses reported, safety inspections completed, hazards corrected within a set time and the percentage of workers with up-to-date training.
Neither is better on its own. Leading indicators help prevent incidents, while lagging indicators confirm results. Most organizations use both together.
Fewer, well-chosen measures usually work better than many. Three to six indicators tied to your most serious risks are often enough to start.
