OSHA uses recordable incident rates to determine where different classifications of companies (manufacturing, food processing, textiles, machine shops, etc.) compare to each other with regard to past safety performance.
OSHA has established specific mathematical formula that enables any company to report the following data so they are comparable to any industry or group.
- Recordable Incident Rate
- Days Away Rate
- Job Transfer / Restriction Rate
- DART Rate
The Rate Data feature allows IMS administrators to create current year reporting by month so that you can compare the actual number of reported incidents to your established target. You can:
- Add current year data by month; update the rate table as often as you like with monthly entries
- Create historical reports as far back as nine years from the current year for each month in previous years
- Produce the Incidence Rates Report by establishment to compare incidents to your established targets. Please refer to the Incidence Rates Report article for an overview and instructions to run the report
- Display current and previous years
Refer to the following articles to set up rate data:
- Rate Data: Add, Edit and Delete: describes how to add, edit and delete current year data by month.
- Rate Data:Import and Export: describes how to add historical data by establishment for one or more years.
RATE DATA DEFINITIONS
Rate data entered appears on the Incidence Rates Report and is used to calculate the following rates listed below. Rate Data terms vary throughout the industry. The term Convergence Training uses in the Incidence Rates Report is in bold followed by the terms used industry-wide to describe the same rate.
- Recordable Incident Rate (AKA OSHA Recordable Incident Rate, Rate Incident Frequency (RIF), Total Recordable Incident Rate (TRIR))
- Days Away Rate (AKA Lost Time Incident Frequency (LTIF), Lost Time Case Rate (LTC) Lost Workday Rate)
- Job Transfer/Restriction Rate (AKA Job Transfer/Restriction Rate)
- DART Rate (Days Away, Restricted and Transfer Rate)
RATE DATA CALCULATIONS
The formulas used by the IMS are provided by the Bureau of Labor and Statistics.
In order to run the formula, the IMS requires the recordable count, days away count and the transfer/restriction count. The IMS automatically aggregates the counts once you begin using the IMS to report incidents.
For example, if your company begins using the IMS in January of 2019, the IMS will aggregate the total number of recordable incidents, days away, and transfer/restriction count every month in 2019. After the IMS Administrator adds the Hours Work Actual and Number of Employees, the IMS will run the formula to come up with the Recordable Rate, Days Away Rate, Transferred/Restricted Rate and the DART Rate when you run the Incidence Rate Report.
Historical data is useful if you would like the IMS to produce the Incidence Rates Report so that you can compare totals from a previous year to the current year. Historical data is optional and you can add entries as far back as nine years from the current year.
Therefore, if you want the IMS to calculate the rates for 2018, you have to manually enter the recordable count, days away count, transfer/restriction count and the hours worked actual on the Historical tab of the Edit Rate Data screen for any month prior to recording incidents in the IMS.
The 200,000 hours in the formula represent the equivalent of 100 employees working 40 hours per week, 50 weeks per year, and provides the standard base for the incidence rates.
A = Hours Worked Actual | B = Recordable Count | C = Days Away Count |
D = Transfer/Restriction Count
