The verdict

Mathews Mechanical runs at 132% of its industry's injury rate - more dangerous than the typical Mechanical contractors workplace, earning a grade D.

Mathews Mechanical: 3.7 TCR = 132% of Mechanical contractors BLS 2.8 · 3y Form 300A (see methodology below)

Mathews Mechanical safety composite

Mathews Mechanical scores strongest on fatalities (safer than 51% of same-industry peers) and weakest on dart rate (safer than 18%), 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).
