The verdict

HammerHead Trenchless runs at 22% of its industry's injury rate - far safer than the typical Construction machinery manufacturing workplace, earning a grade A.

HammerHead Trenchless: 0.7 TCR = 22% of Construction machinery manufacturing BLS 3.3 · 2y Form 300A (see methodology below)

HammerHead Trenchless safety composite

HammerHead Trenchless scores strongest on total case rate (tcr) (safer than 95% 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).
