page 64 says total injury rate as of 200000hours worked is 1.37 as of FY17 so as to find total injury rate of per million head we will have to multiply it with 5 and number comes to 6.85 injuries per million hours worked.

pg. 64

"Total Recordable Incident Rate (TRIR)/200,000 hours FY2017

1.37"

pg. 41

"These tactics are paying off: Campbell saw a 13 percent reduction in its Lost Time Incident Rate (0.23 to 0.20) between FY2016 and FY2017 and a 30 percent reduction in its Total Recordable Incident Rate (1.96 to 1.37). Though these are best-in-class achievements, we will continue to strive for zero injuries by focusing on the small, day-to-day actions that make everyone safer."

(Calculation: 1.37*2 = 2.74)
