I am trying to figure out the percentage of Lost Time Injuries using OSHA's standard 200,000 (100 people x 40 hrs x 50 wks = 200,000).  We have 143 people x 40 hrs x 50 wks = 286,000 hrs worked.  So if there is 1 injury  the equation is   1x200,000 / 286,000 = 0.6993   Now would I take .699 / 200,000 = x / 100 to get our percent?
