U.S. Bureau of Labor Analysis

The number of injuries, illnesses, or lost workdays related to a common exposure base of 100 full-time workers as used by the U.S. Bureau of Labor Statistics. The common exposure base enables one to make accurate inter-industry comparisons, trend analysis over time, or comparisons among firms regardless of size. This rate is calculated as IR = (N/EH) X 200,000, where N is number of injuries and/or dlnesses or lost work days, EH is total hours worked by all employees during the calendar year, and 200,000 is the base for 100 full-time equivalent workers (working 40 hours per week, 50 weeks per year).
