Total Case Incident Rate

Written by Jerry Ratzlaff on . Posted in Safety Engineering

Total case incident rate/total recordable incident rate, abbreviated as TCIR or TCIR/TRIR, a dimensionless number, is the number of work-related injuries per 100 full-time workers during a one year period.

 

total case incident rate/total recordable incident rate formula

\(\large{ TCIR/TRIR =  \frac{ TNRI \; 200,000}{ TNHW }  }\)   

Where:

\(\large{ TCIR/TRIR }\) = total case incident rate/total recordable incident rate

\(\large{ TNRI }\) = total number of recordable incidents

\(\large{ TNHW }\) = total number of hours worked by all employees
