The verdict

Micron SIG runs at 4% of its industry's injury rate - far safer than the typical Semiconductor devices manufacturing workplace, earning a grade A.

Micron SIG: 0.1 TCR = 4% of Semiconductor devices manufacturing BLS 3.3 · 5y Form 300A (see methodology below)

Micron SIG safety composite

Micron SIG scores strongest on total case rate (tcr) (safer than 95% 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).

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%).

Micron SIG held a steady TCR band

Micron SIG's TCR held near 0.0 from 0.0 in 2020 to 0.0 in 2024. Peak filing year was 2023 at 0.7 TCR. In 2024, DART was 0× this establishment's average TCR (severity share of cases).

Micron SIG (138 employees, TCR 0.1) among 29 same-industry peers, split at the industry median of 216 employees and a TCR of 0.9

Micron SIG has fewer employees than the Semiconductor devices manufacturing 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.
