Using metrics is one of the most effective ways to evaluate and analyze safety in the workplace and this one stop shop calculator will help you find the relevant safety rates for your facility. Incident rates are utilized by OSHA to measure safety performance across industries and by safety managers to track past performance and establish benchmarks for the future.
Simply use the information from your OSHA Form 300: Log of Work-Related Injuries and Illnesses and your OSHA Form 300A: Summary of Work-Related Injuries and Illnesses. Enter the relevant information into the fields below and calculate! With just a few points of data you can find the Total Case Incident Rate, OSHA’s Recordable Severity Rate, and more. Analyze results to look for areas in your safety program needing improvement, use NAICS codes to see how your organization is measuring up in the industry, and start monitoring safety rates long term.
|1||Total Case Incident Rate (OSHA Recordable Incident Rate)||TCIR||Number of recordable incidents (injuries and illness) per 100 full-time employees.||(Number of OSHA recordable cases x 200,000) / Total number of hours worked|
|2||Lost Time Case Rate||LTIR||Number of incidents resulting in lost time per 100 full-time employees.||(Number of lost time cases x 200,000) / Total number of hours worked|
|3||Lost Workday Rate (Lost Time Injury Rate)||LWDR||Number of lost workdays days to injury or illness per 100 full-time employees.||(Number of lost workdays x 200,000) / Total number of hours worked|
|4||Severity Rate||Severity||The number of the lost days occurred compared to the number of actual incidents.||Number of lost workdays / Number of recordable incidents.|
|5||Days Away/Restricted or Job Transfer Rate||DART||The number of incidents resulting in lost worktime due to injury or illness per 100 employees.||(Number of incidents that had one or more lost days, one or more restricted days, or that resulted in an employee transferring) cases x 200,000 / Total number of hours worked|
|6||OSHA Recordable Severity Rate||TRSR||The average number of lost days per recordable incident.||(Number of lost work days + Number of restricted or transferred days) x 200,000 / Total number of hours worked|
|7||Lost Time Injury Frequency Rate||LTIFR||The number of injuries resulting in lost time per 1 million hours worked.||(Number of lost time cases x 1,000,000) / Total number of hours worked|
|8||Total Recordable Injury Frequency Rate||TRIFR||Number of fatalities, lost time injuries, substitute work, and other injuries that required treatment from a medical professional per 1 million hours worked.||(Recorded incidents (GHIJ) X 200,000) / Total number of hours worked|
