I'm finding all your various rate calculations to be confusing. Please provide the formulas and definitions for your relevant calculations--specifically TCR, DAFWII, and DART. We'd like to benchmark ourselves and do annual comparisons.

The various rates are incidence rates per 100 full-time workers and are calculated using the following formula: (Number of injuries and illnesses X 200,000) / Employee hours worked = Incidence rate
For the Number of injuries and illnesses in the formula above:

TCR (Total Case Rate) -- Use the total number of injuries and illnesses --- columns G, H, I, and J from the OSHA 300 Log

DART (Rate of cases involving Days Away, Restricted work, or job Transfer) -- Use the total number of injuries and illnesses that involved either days away from work and/or restricted work activity --- columns H and I from the OSHA 300 Log

DAFWII (Rate of cases involving Days Away From Work) -- Use the total number of injuries and illnesses that involved days away from work --- column H from the OSHA 300 Log
