The verdict

Main runs at 505% of its industry's injury rate - far more dangerous than the typical Plumbing and heating contractors workplace, earning a grade F.

Main: 14.1 TCR = 505% of Plumbing and heating contractors BLS 2.8 · 3y Form 300A (see methodology below)

Main safety composite

Main scores strongest on fatalities (safer than 51% of same-industry peers) and weakest on dart rate (safer than 0%), 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).
