Insuranceopedia explains Serious Injury Frequency Rate
This is the formula for the serious injury frequency rate: the number of injuries during 1,000,000 working hours. So, if 200 injuries happened during 1,000,000 working hours, the serious injury rate is 0.0002%. Note that working hours exclude paid vacations.
This calculation is one way of knowing just how safe a workplace is considered to be. This is also a way of knowing whether the safety programs installed are effective or not. Insurance companies that provide group insurance for employees can use the data to assess the premiums and even decline insurance.
