The verdict

Doble Engineering Company runs at 12% of its industry's injury rate - far safer than the typical Instruments for measuring electrical quantities manufacturing workplace, earning a grade A.

Doble Engineering Company: 0.4 TCR = 12% of Instruments for measuring electrical quantities manufacturing BLS 3.3 · 5y Form 300A (see methodology below)

Doble Engineering Company safety composite

Doble Engineering Company scores strongest on total case rate (tcr) (safer than 82% of same-industry peers) and weakest on fatalities (safer than 50%), 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).
