Therma LLC: 1.3 TCR = 46% of Plumbing and heating contractors BLS 2.8 · 8y Form 300A (see methodology below)

Therma LLC safety composite

Therma LLC scores strongest on total case rate (tcr) (safer than 82% 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).
