The verdict

Semicoa runs at 104% of its industry's injury rate - about level with the typical Optoelectronic devices manufacturing workplace, earning a grade C.

Semicoa: 3.4 TCR = 104% of Optoelectronic devices manufacturing BLS 3.3 · 4y Form 300A (see methodology below)

Semicoa safety composite

Semicoa scores strongest on fatalities (safer than 51% of same-industry peers) and weakest on dart rate (safer than 1%), 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).

Semicoa (65 employees, TCR 3.4) among 29 same-industry peers, split at the industry median of 216 employees and a TCR of 0.9

Semicoa has fewer employees than the Optoelectronic devices manufacturing median and a higher injury rate than the industry's median TCR of 0.9. 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.
