Keywords: Frequency rate, severity rate, incidence rate measured by work- related mortality, injury rates, and workers' compensation payments (LARSON Under the “OSHA” Standard used for reporting here, Lost Time Injury Frequency Rate (LTIFR) is calculated as the number of Lost Time Injuries plus fatalities, Accident / incident rates - Measures of accident / incident loss experience within given time periods, as a means of comparison. (Examples: injury frequency rate, 9 Dec 2015 OSHA - Lost Time Incident (LTI) Frequency Rate (per 100 full-time workers) (No. Lost Time Incidents /hours worked in period x 200,000). 3.2 Lost Time Injury Frequency Rate (LTIFR) . 3.3 Medically Treated Injury Frequency Rate (MTIFR) . 3.4 Total Recorded Injury Frequency Rate (TRIFR) .

## 9 Dec 2015 OSHA - Lost Time Incident (LTI) Frequency Rate (per 100 full-time workers) (No. Lost Time Incidents /hours worked in period x 200,000).

In this example, the accident frequency rate is 0.001295 x 100,000 = 129.5. Multiply the number of accidents per a working hour by 200,000 to calculate the accident frequency rate per 200,000 hours. In this example, the accident frequency rate is 0.001295 x 200,000 = 259. An incident rate provides information about recordable injuries and illnesses. The U.S. Department of Labor's Occupational Safety and Health Administration and individual employers use the information to plan for upcoming inspections, gauge the effectiveness of health and safety programs within a single firm, and make industry-wide comparisons. Incidence reflects the number of new cases in relation to the number at risk. Accident Incidence Rate Formula. Number of work-related injuries × 1,000 / Average number of employees. It is a measure of the number of injuries per 1,000 employees and is usually calculated over a period of time, e.g. a year. Computing accident incidence rates and severity can help analyze and correct conditions that cause accidents. A simple formula for calculating accident incidence (frequency) is to: Take the total number of recordable incidents for the year from your OSHA 300. Multiply that number by 200,000, which represents the number of hours worked by 100 full-time employees, …
