The verdict

Phononic runs at 52% of its industry's injury rate - safer than the typical Semiconductor devices manufacturing workplace, earning a grade B.

Phononic: 1.7 TCR = 52% of Semiconductor devices manufacturing BLS 3.3 · 5y Form 300A (see methodology below)

Phononic safety composite

Phononic scores strongest on fatalities (safer than 51% of same-industry peers) and weakest on dart rate (safer than 15%), 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

Phononic: 1.2 → 2.4 TCR

Peak year 2019 @ 3.6 TCR · DART/TCR 0.94× in 2023

Phononic's TCR rose 1.2 from 1.2 in 2018 to 2.4 in 2023. Peak filing year was 2019 at 3.6 TCR. In 2023, DART was 0.94× this establishment's average TCR (severity share of cases).

Where Phononic falls in its industry

437 Semiconductor devices manufact establishments

Safer than 26% of graded establishments in this industry, whose median TCR is 0.9.

Grade B

More dangerous than peersSafer than peers

Narrower to North Carolina alone (the establishments it most directly competes with for workers and contracts): ranked #12 safest of 15 Semiconductor devices manufact employers in North Carolina.

Phononic (164 employees, TCR 1.7) among 29 same-industry peers, split at the industry median of 216 employees and a TCR of 0.9

Phononic 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.
