The verdict

Main Office - Main runs at 26% of its industry's injury rate - far safer than the typical Heating, Plumbing and A/C workplace, earning a grade A.

Main Office - Main: 0.7 TCR = 26% of Heating, Plumbing and A/C BLS 2.8 · 6y Form 300A (see methodology below)

Main Office - Main safety composite

Main Office - Main scores strongest on total case rate (tcr) (safer than 92% 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).

Narrower to Massachusetts alone (the establishments it most directly competes with for workers and contracts): ranked #7 safest of 140 Heating, Plumbing and A/C employers in Massachusetts.

Main Office - Main (57 employees, TCR 0.7) among 29 same-industry peers, split at the industry median of 60 employees and a TCR of 3.3

Main Office - Main has fewer employees than the Heating, Plumbing and A/C median and a lower injury rate than the industry's median TCR of 3.3. Workforce size and injury rate do not always move together within the same industry -- some of its smaller peers run higher rates than its larger ones, and vice versa.
