Safety statistics and classifications We use simple classifications.
Proactive incidents - Unsafe acts, Unsafe conditions, near miss
Reactive incidents - First Aid/Minor, Medical treatment (MTI), Restricted work (RWT), Lost Time (LTI), property damage and environmental.
Corrective actions designed to eliminate or minimise future risks.
No rewards or messages for "day's since last incident".
Recording stats is only part of the job. I believe corrective actions is where most improvement opportunity is lost. No corrective actions imposed or implemented, status quo prevails.
