SureHire explains Injury Severity Rate
The injury severity rate is a way to track how many injuries are serious vs minor. This is a way to gauge if there is a serious issue that needs to be addressed with regards to safety in a particular area of a company or if there is a shift in events over time.
The data is used to determine the safety performance of an organization, shift or department, and provides guidelines for training and safety observations in the workplace. A high severity rate indicates the need for redesigning currently implemented standards to provide a safer work environment.
