The verdict

1-Boise Main Site runs at 10% of its industry's injury rate - far safer than the typical Diodes, solid-state (e.g., germanium, silicon), manufacturing workplace, earning a grade A.

1-Boise Main Site: 0.3 TCR = 10% of Diodes, solid-state (e.g., germanium, silicon), manufacturing BLS 3.3 · 4y Form 300A (see methodology below)

1-Boise Main Site safety composite

1-Boise Main Site scores strongest on total case rate (tcr) (safer than 81% of same-industry peers) and weakest on fatalities (safer than 51%), 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).

Narrower to Idaho alone (the establishments it most directly competes with for workers and contracts): ranked #5 safest of 16 Diodes, solid-state (e.g., ger employers in Idaho.

1-Boise Main Site (6,035 employees, TCR 0.3) among 29 same-industry peers, split at the industry median of 216 employees and a TCR of 0.9

1-Boise Main Site has more employees than the Diodes, solid-state (e.g., germanium, si median and a lower 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.
