The verdict

Limbach - WPA runs at 100% of its industry's injury rate - about level with the typical Mechanical contractors workplace, earning a grade C.

Limbach - WPA: 2.8 TCR = 100% of Mechanical contractors BLS 2.8 · 2y Form 300A (see methodology below)

Limbach - WPA safety composite

Limbach - WPA scores strongest on dart rate (safer than 80% 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).
