The verdict

Main runs at 70% of its industry's injury rate - safer than the typical Electrical Contractors and Other Wiring Installation Contractors workplace, earning a grade B.

Main: 2.0 TCR = 70% of Electrical Contractors and Other Wiring Installation Contractors BLS 2.8 · 2y Form 300A (see methodology below)

Main safety composite

Main scores strongest on total case rate (tcr) (safer than 59% of same-industry peers) and weakest on dart rate (safer than 33%), 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).
