Measures the rate of work-related injuries and illnesses, based on OSHA reporting guidelines. Incidence rates represent the number of injuries and illnesses per 100 full-time workers. The incident rate calculation is: (N/EH) x 200,000, where N = number of injuries and illnesses; EH = total hours worked by all employees during the calendar year; and 200,000 = base for 100 equivalent full-time workers (working 40 hours per week, 50 weeks per year). Details regarding recordability of nonfatal work-related injuries and illnesses can be found here: Total recordable incidents indicates both minor and major injuries and illnesses that required medical treatment or resulted in lost workdays.
