M&M Sdl: 7.8 TCR = 235% of Ducts, sheet metal, manufacturing BLS 3.3 · 3y Form 300A (see methodology below)

M&M Sdl safety composite

M&M Sdl scores strongest on dart rate (safer than 61% of same-industry peers) and weakest on total case rate (tcr) (safer than 22%), 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).
