The verdict

Stuart Mechanical runs at 181% of its industry's injury rate - more dangerous than the typical Mechanical contractors workplace, earning a grade D.

Stuart Mechanical: 5.1 TCR = 181% of Mechanical contractors BLS 2.8 · 7y Form 300A (see methodology below)

Stuart Mechanical safety composite

Stuart Mechanical scores strongest on dart rate (safer than 80% of same-industry peers) and weakest on total case rate (tcr) (safer than 33%), 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).
