The steps outlined in this handout will help you to select a NAICS. LTIFR will typically be calculated for a specific workplace or project, but it can also be expanded to measure safety in specific regions or industries as well. (Number of lost time cases x 200,000) / total number of. This is commonly called either the “total case incident rate” or just the “incident rate”. Total recordable incident rate (TRIR) is one of many safety indicators used to evaluate the effectiveness of a company’s safety efforts. Firstly, divide the total number of lost time injuries in a given time period by the total number of hours worked in the given period. LTIFR = 2. Calculate Injury/Illness Rates. To calculate your LTIFR, simply.
