The verdict

Diverse Optics Inc runs at 37% of its industry's injury rate - far safer than the typical Lenses (except ophthalmic) manufacturing workplace, earning a grade A.

Diverse Optics Inc: 1.2 TCR = 37% of Lenses (except ophthalmic) manufacturing BLS 3.3 · 2y Form 300A (see methodology below)

Diverse Optics Inc safety composite

Diverse Optics Inc scores strongest on dart rate (safer than 77% 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).

Grade A

More dangerous than peersSafer than peers

Narrower to California alone (the establishments it most directly competes with for workers and contracts): ranked #6 safest of 20 Lenses (except ophthalmic) man employers in California.

Diverse Optics Inc (35 employees, TCR 1.2) among 29 same-industry peers, split at the industry median of 80 employees and a TCR of 1.8

Diverse Optics Inc has fewer employees than the Lenses (except ophthalmic) manufacturing median and a lower injury rate than the industry's median TCR of 1.8. Workforce size and injury rate do not always move together within the same industry -- some of its smaller peers run higher rates than its larger ones, and vice versa.
