The verdict

DMI Corp. runs at 38% of its industry's injury rate - far safer than the typical Mechanical contractors workplace, earning a grade A.

DMI Corp.: 1.1 TCR = 38% of Mechanical contractors BLS 2.8 · 4y Form 300A (see methodology below)

DMI Corp. safety composite

DMI Corp. scores strongest on total case rate (tcr) (safer than 86% of same-industry peers) and weakest on fatalities (safer than 51%), blended into one 0-100 breakdown against same-industry peers. A missing measure drops out and redistributes its weight rather than deflating the score. This is a per-dimension breakdown, distinct from the single letter grade above it (which weights TCR alone against the BLS industry benchmark).
