The verdict

Diamond Antenna and Microwave runs at 21% of its industry's injury rate - far safer than the typical Microwave components manufacturing workplace, earning a grade A.

Diamond Antenna and Microwave: 0.7 TCR = 21% of Microwave components manufacturing BLS 3.3 · 7y Form 300A (see methodology below)

Diamond Antenna and Microwave safety composite

Diamond Antenna and Microwave scores strongest on total case rate (tcr) (safer than 84% 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).
