The verdict

TSI Semiconductors runs at 41% of its industry's injury rate - far safer than the typical Semiconductor devices manufacturing workplace, earning a grade A.

TSI Semiconductors: 1.4 TCR = 41% of Semiconductor devices manufacturing BLS 3.3 · 2y Form 300A (see methodology below)

TSI Semiconductors safety composite

TSI Semiconductors 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).

Benchmarked live against every credibly-rated employer in the same NAICS industry code in the current OSHA extract (a segment must have at least 8 rated peers to benchmark). Not a legal or compliance determination; PlainSafetyScore's own weighting (TCR 40%, DART 35%, fatalities 25%).

Rising injury rate

TSI Semiconductors: 1.0 → 1.7 TCR

Peak year 2022 @ 1.7 TCR · DART/TCR 0.96× in 2022

TSI Semiconductors's TCR rose 0.8 from 1.0 in 2021 to 1.7 in 2022. In 2022, DART was 0.96× this establishment's average TCR (severity share of cases).

TSI Semiconductors (234 employees, TCR 1.4) among 29 same-industry peers, split at the industry median of 216 employees and a TCR of 0.9

TSI Semiconductors has more 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.
