ABC Corp has injuries and illnesses logged in Form 300 shown in figure [attached at the end]. If the
company has 150 employees worked in 2012, calculate (a) OSHA incident rate and (b) DART rate -
Answers (a) 4 Incident Rate
OSHA Incident Rt = [(Total number of incidence of work-related injury and illness)*(200,000)] / [Hours
worked by all employees during the period covered = 200,000 hours worked per 100 employees OR n
employees * 40 * 50]
Use Form 300 for Total number of incidence of work-related injury and illness. Should be # of people.
OSHA Incident Rt = [(6*200,000)]/(150*40*50) = 4
(b) OSHA DART Rt = [(Number of incidents w/ Days Away, Restricted, Transferred x 200,000)] / (Hours
worked by all employees during period covered)
OSHA DART Rt = [(5+10)*200,000] / (100*50*40)
