Figure 11: Workplace minor injury rate, 2011-2018 Figure 12: Proportion of workplace minor injuries by cause of injury, 2014-2018 Figure 13: Number of dangerous occurrences, 2011-2018 Figure 14: Accident frequency rate, 2009-2018 Figure 15: Accident severity rate, 2009-2018 Figure 16: Occupational disease incidence rate, 2009-2018 The website delivers national work health and safety and workers’ compensation data in an intuitive, user-friendly way. For example, if you you were to calculate the frequency rate of lost time injuries (LTI's), you would first find the number of lost time injuries in the. Calculating TRF. The total hours worked in this period (for all employees) was 800,000. OSHA's accident rate calculation is performed by multiplying the number of recorded incidents by 200,000, then dividing the result by the number of hours worked in the organization. The result is then multiplied by 200,000. (The hours are derived from the fact that 1 employee works 2000 hours per year, thus 100 employees work 200 000 per year). An LTIFR of 7, for example, shows that 7 lost time injuries occur on. Incidence rates (density) can be measured in a closed cohort or in an open population. An incidence rate of injuries and illnesses may be computed from the following formula: (Number of injuries and illnesses X 200,000) / Employee hours worked = Incidence rate. The formula for calculating lost time injury frequency rate is the number of lost time injuries multiplied by 1,000,000, divided by the employee total hours worked. Severity Rate (S. F = (Number of Fatal Accident injury x 1000000) / Number of manhours worked. If it’s low, it means the working conditions are safe. 1 Tier 1 Indicator Purpose 3. Mechanical Engineering. The number of reported accidents is derived from your operations, as is the total hours worked, while the number 200,000 is used in a number of safety KPI's to standardise the AFR. An injury frequency rate is the number of injuries per 1,000,000 employee-hours worked. ) DISABILING INJURY SEVERITY RATE. A lost time injury is an injury sustained on the job by worker that results in the loss of productive work time.
