Mann Mechanical: 0.9 TCR = 32% of Plumbing and heating contractors BLS 2.8 · 4y Form 300A (see methodology below)

Mann Mechanical safety composite

Mann Mechanical scores strongest on total case rate (tcr) (safer than 89% 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).
