The verdict

Coherent Monrovia runs at 0% of its industry's injury rate - about level with the typical Laboratory analytical optical instruments (e.g., microscopes) manufacturing workplace, earning a grade C.

Coherent Monrovia: 0.0 TCR = 0% of Laboratory analytical optical instruments (e.g., microscopes) manufacturing BLS 3.3 · 4y Form 300A (see methodology below)

Coherent Monrovia safety composite

Coherent Monrovia scores strongest on total case rate (tcr) (safer than 100% 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).

Where Coherent Monrovia falls in its industry

145 Laboratory analytical optical establishments

Safer than 100% of graded establishments in this industry, whose median TCR is 1.8.

Grade C

More dangerous than peersSafer than peers

Narrower to California alone (the establishments it most directly competes with for workers and contracts): ranked #0 safest of 20 Laboratory analytical optical employers in California.

Coherent Monrovia (22 employees, TCR 0.0) among 29 same-industry peers, split at the industry median of 80 employees and a TCR of 1.8

Coherent Monrovia has fewer employees than the Laboratory analytical optical instrument 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.
