Thoma Electric runs at 36% of its industry's injury rate - far safer than the typical Electrical contractors workplace, earning a grade A.

Thoma Electric: 1.0 TCR = 36% of Electrical contractors BLS 2.8 · 5y Form 300A (see methodology below)

Thoma Electric safety composite

Thoma Electric scores strongest on total case rate (tcr) (safer than 81% 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).
