     Calculate the LWDI for a firm that has 40 employees and for the year has had 12 work-related injury cases, each involving one or more lost workdays?  12  30  16.5  indeterminate from the data supplied.  Calculate the LWDI for a firm that has 15 employees and for the year has had 11 work-related injury cases, each of which involved one or more lost workdays?  73.3  36.5  8.6  Indeterminate from the data supplied 
  
  Solution
Assume a 100 worker firm with 40 hr week and 50 weeks/year
Total EH = 100* 40* 50 = 200,000
LWDI = No of Injuries * 200,000/ No of workers * Yearly Hrs/worker
a) 12 * 200,000 /40* 2000 = 30
b) 11 * 200,000/15*2000 = 73.3
