The verdict

pSemi runs at 23% of its industry's injury rate - far safer than the typical Diodes, solid-state (e.g., germanium, silicon), manufacturing workplace, earning a grade A.

pSemi: 0.8 TCR = 23% of Diodes, solid-state (e.g., germanium, silicon), manufacturing BLS 3.3 · 3y Form 300A (see methodology below)

pSemi safety composite

pSemi scores strongest on total case rate (tcr) (safer than 60% of same-industry peers) and weakest on dart rate (safer than 39%), 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).

pSemi 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.
