Your company’s safety statistics play a major role in profit and loss for your business. Positive safety stats lead to more customers, more work, and an overall safer workplace. Acronyms are commonly used for these safety stats, but what do they mean? Here, I explain the common safety statistics required and how they are calculated.
Some of the common statistics calculated and reported include Total Recordable Incident Rate (TRIR), Days Away/Restricted Transfer Rate (DART), and Lost Time Case (LTC) Rate.
Total Recordable Incident Rate (TRIR)
Total Recordable Incident Rate is probably the most common safety statistic required by customers. Your company’s TRIR gives an overview of your safety performance. This is usually reported for a 3-year period. Customers use this information to determine the risk involved when considering who to hire. OSHA also uses this information to monitor safety performance. The TRIR is calculated as follows:
Number of Incidents x 200,000 / total number of hours worked in a year
The 200,000 figure represents the number of hours that 100 employees working 40 hours per week, 50 weeks per year would work. Hours worked by third-party employees, if they fall under the company’s supervision, should be included in the total hours worked. Vacation hours or any kind of personal leave should not be included.
Days Away/Restricted Transfer Rate (DART)
Some customers may request your company’s DART. This calculation gives the rate for days away from work and restricted transfer rate. The DART is calculated as follows:
OSHA recordable injuries and illnesses that result in Days Away; Restricted; or Transferred x 200,000 / total number of hours worked in a year
Lost Time Case (LTC) Rate
A less commonly requested rate is the Lost Time Case (LTC) Rate. Although uncommon, some safety compliance companies require this calculation. This one is fairly self-explanatory as it gives the rate for lost time cases.
The majority of companies only ask for your TRIR, while others ask for more. These rates are compared with others in the same industry to determine the level of risk you bring to the project. When clients are comparing similar companies to decide who to hire, your positive safety stats can put your company at the top of that list.
