Definition
Occupational injury - an injury which results from a work-related event or a single instantaneous exposure in the work environment (occupational accident). Where more than one person is injured in a single accident, each case of occupational injury should be counted separately. If one person is injured in more than one occupational accident during the reference period, each case of injury to that person should be counted separately. Recurrent absences due to an injury resulting from a single occupational accident should be treated as the continuation of the same case of occupational injury not as a new case.
Case without workdays lost - where the injured person required only first aid or medical treatment on the day of the accident and was able to perform again, on the day after the accident, the normal duties of the job or position occupied at the time of the occupational accident.
