Occupational Injuries and Illnesses Incidence Rate Calculator and Comparison Tool

The number of hours all employees actually worked

Hours Worked should not include any nonwork time, even though paid, such as vacation, sick leave, holidays, etc. If actual hours worked are not available for employees paid on commission, by salary, or by the mile, etc., hours worked may be estimated on the basis of scheduled hours or 8 hours per workday. This number is also available from several sources:

From your Summary of Work-Related Injuries and Illnesses (Summary), OSHA's Form 300A 2nd section (Total Number)
From the BLS Survey of Occupational Injuries and Illnesses form, if your company was surveyed for the calendar year for which incidence rates are desired
From payroll or other time records
