The verdict

Main runs at 23% of its industry's injury rate - far safer than the typical Boiler and pipe insulation installation workplace, earning a grade A.

Main: 0.6 TCR = 23% of Boiler and pipe insulation installation BLS 2.8 · 3y Form 300A (see methodology below)

Main safety composite

Main scores strongest on total case rate (tcr) (safer than 91% of same-industry peers) and weakest on dart rate (safer than 29%), 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).
