Frequency rate ( called in French “taux de fréquence“) is the number of occupational accidents with leave for 1 000 000 worked hours
Method of calculation :

Frequency index ( called in French “indice de fréquence“) is the number of occupational accidents for 1 000 employees.
To calculate the frequency index, you have to divide the number of accidents with a leave ( work stopped more than one day) by the number of employees and then you multiply by , 1 000
Fréquency index = number of accidents with leave x 1 000 / number of employees
