Superior Plumbing & Heating safety composite

Superior Plumbing & Heating scores strongest on fatalities (safer than 51% of same-industry peers) and weakest on total case rate (tcr) (safer than 14%), 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 Alaska alone (the establishments it most directly competes with for workers and contracts): ranked #7 safest of 13 Air system balancing and testi employers in Alaska.

Superior Plumbing & Heating (23 employees, TCR 8.8) among 29 same-industry peers, split at the industry median of 60 employees and a TCR of 3.3

Superior Plumbing & Heating has fewer employees than the Air system balancing and testing median and a higher injury rate than the industry's median TCR of 3.3.
