Total Case Incident Rate (TCIR)

The Total Case Incident Rate, or "TCIR" is a common method used to report workplace injuries. It is different from the DART Rate only in the types of injuries measured. The DART Rate measures only DART cases, while the "TCIR" includes all of the work-related cases.

The Total Case Incident Rate (TCIR) is defined as the number of work-related cases per 100 full-time workers during a one year period. This number will be total annual injuries and illnesses (N) of your own employees plus all contractor/subcontractor employees times 200,000 divided by the total number of hours worked (EH).

Use of the TCIR to report workplace injuries allows comparison of accident and injury statistics across industries, among industry segments, and from one year to the next. You can calculate the TCIR using the following equation:

For example, if an employer reported 10 work-related injury and illness cases in 2019, and they worked 1,000,000 hours that year, then the 2019 TCIR for that employer would be (10 x 200,000) / 1,000,000 = 2.

2-7. Calculate the TCIR for a company that recorded 75 work-related cases and a total of 3,000,000 hours worked by employees during the year.

TCIR = ((N x 200,000) / EH)
