The verdict

Capital Mechanical: 6.9 TCR = 247% of Plumbing contractors BLS 2.8 · 6y Form 300A (see methodology below)

Capital Mechanical safety composite

Capital Mechanical scores strongest on fatalities (safer than 51% of same-industry peers) and weakest on dart rate (safer than 12%), 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).
