What Is TCIR?
Definition, formula, and example for Total Case Incident Rate.
Quick definition
TCIR stands for Total Case Incident Rate. It is the number of OSHA-recordable injury and illness cases per 100 full-time workers over a year. TCIR is commonly used as another label for the total-recordable rate also called TRIR; confirm the terminology a customer or reporting form requires before you submit a number. The usual inputs and formula are the same.
TCIR formula
TCIR = (Number of recordable cases × 200,000) ÷ Total hours worked by all employees
The 200,000 constant represents 100 full-time employees working 40 hours a week for 50 weeks. It lets a 10-person shop and a 500-person employer be compared on the same scale.
Worked example
A contractor logs 3 recordable cases and 150,000 total hours worked in the year. TCIR = (3 × 200,000) ÷ 150,000 = 4.0. That means about 4 recordable cases per 100 full-time workers.
TCIR vs TRIR vs DART
TCIR and TRIR count all recordable cases from your OSHA 300 log. DART counts only the more severe cases involving days away, restricted work, or job transfer. Customers, insurers, and prequalification forms may use any of these labels, so confirm which one is being asked for before you submit a number.
Where TCIR comes from
The case count comes from your OSHA Form 300 log, and the hours come from payroll or timekeeping. Keep the method the same from period to period so trends are meaningful. Rivkor ties incident records, OSHA logs, and rate calculations together so you are not rebuilding the math in a spreadsheet each quarter.
