It provides an idea about the organization’s efforts to protect the workers from work related hazards. resulted in days away from work, restricted work activity, and/or job transfer. Its formula: F = (number of disabling injuries x 106)/employee hours of exposure. 2 cases per 10,000 full-time equivalent workers compared to 37. The DART rate. (4 x 200,000)/ (300 x 40 x 50) = 1. Let’s say we want the number of lost time injuries per 1 000 000 hours. The percent relative standard errors in tables A1 and A2 are a measure of sampling error, one of the measures of the reliability of our survey estimates. This puts all of the organizations on relatively equal footing when it comes to measuring rates. 1 Incidence rate represents the number of fatalities per 100,000 workers.
