Safety Incident Rate

operationalbehavioral · safety · rate · unit

Recordable safety incidents per exposure hours.

How it’s computed

Formula
incidents × 200,000 / hours worked
Measurement model
operational (a formula over systems data) — not a reflective survey scale; “reliability” here means data quality, not internal consistency

What it operationalizes

This metric measures the construct(s) below from operational data. Through them, it connects to the meta-analytic relationship network — the bridge from what you measure operationally to what the science knows.

What we know

Synthesized Bayesian priors over relationships involving this metric’s construct(s) — the meta-analytic evidence, with 95% confidence intervals and between-study heterogeneity (I²). Follow a row for the full distribution, contributing studies, and code.

As accidents/injuries occur infrequently and are not effective indicators of SP, a more refined measure of SP is suggested by the researchers such as “safety behavior” that is measured using safety compliance and safety participation [1,2,4,23,25,26]. disputes

Regarding engagement and the accident rate, there is evidence that when workers are engaged, the perceived job security climate is linked to a decrease in labour demands, and in general, there is a decrease in incidents of occupational accidents, as well as a lower frequency of behaviours that expose them to accidents [30]. supports
