The verdict

H.H.S. Mechanical Contractors runs at 225% of its industry's injury rate - far more dangerous than the typical Mechanical contractors workplace, earning a grade F.

H.H.S. Mechanical Contractors: 6.3 TCR = 225% of Mechanical contractors BLS 2.8 · 2y Form 300A (see methodology below)

H.H.S. Mechanical Contractors safety composite

H.H.S. Mechanical Contractors scores strongest on dart rate (safer than 80% of same-industry peers) and weakest on total case rate (tcr) (safer than 25%), 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).
