Fatal Accident Rate

Fatal Accident Rate

Le Fatal Accident Rate (FAR) ou Taux d'Accident Fatal est un indicateur d'accidentabilité utilisé pour classer la dangerosité d'une activité.

Calcul

Le FAR correspond au nombre de décès pour une activité donnée rapporté à 100 millions d'heures de cette même activité soit 50000 années de travail ou 11500 années pleines[1].

Exemple

Si 2 décès ont été constatés dans une entreprise de 30000 personnes travaillant 35 heures par semaine chacune (1355 heures par an) :

FAR=2.\frac{10^{8}}{30000.1355}=4,92
