The verdict

HMADH01 runs at 40% of its industry's injury rate - far safer than the typical industry workplace, earning a grade A.

HMADH01: 0.2 TCR = 40% of industry BLS 0.5 · 3y Form 300A (see methodology below)

HMADH01 safety composite

HMADH01 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).
