The verdict

Research Electro Optics Inc. runs at 26% of its industry's injury rate - far safer than the typical Lens grinding (except ophthalmic) workplace, earning a grade A.

Research Electro Optics Inc.: 0.9 TCR = 26% of Lens grinding (except ophthalmic) BLS 3.3 · 2y Form 300A (see methodology below)

Research Electro Optics Inc. safety composite

Research Electro Optics Inc. scores strongest on total case rate (tcr) (safer than 75% 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).
