The verdict

Silicon Microstructures, Inc. runs at 38% of its industry's injury rate - far safer than the typical Semiconductor devices manufacturing workplace, earning a grade A.

Silicon Microstructures, Inc.: 1.3 TCR = 38% of Semiconductor devices manufacturing BLS 3.3 · 2y Form 300A (see methodology below)

Silicon Microstructures, Inc. safety composite

Silicon Microstructures, Inc. scores strongest on fatalities (safer than 51% of same-industry peers) and weakest on dart rate (safer than 19%), 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 #76 safest of 128 Semiconductor devices manufact employers in California.

Silicon Microstructures, Inc. (80 employees, TCR 1.3) among 29 same-industry peers, split at the industry median of 216 employees and a TCR of 0.9

Silicon Microstructures, Inc. has fewer employees than the Semiconductor 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.
