The verdict

Masimo Semiconductor runs at 24% of its industry's injury rate - far safer than the typical Semiconductor devices manufacturing workplace, earning a grade A.

Masimo Semiconductor: 0.8 TCR = 24% of Semiconductor devices manufacturing BLS 3.3 · 8y Form 300A (see methodology below)

Masimo Semiconductor safety composite

Masimo Semiconductor scores strongest on dart rate (safer than 77% 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%).

Masimo Semiconductor held a steady TCR band

Masimo Semiconductor's TCR held near 0.0 from 0.0 in 2017 to 0.0 in 2024. Peak filing year was 2023 at 3.4 TCR. In 2024, DART was 0× this establishment's average TCR (severity share of cases).

Where Masimo Semiconductor falls in its industry

437 Semiconductor devices manufact establishments

Safer than 58% of graded establishments in this industry, whose median TCR is 0.9.

Grade A

More dangerous than peersSafer than peers

Narrower to New Hampshire alone (the establishments it most directly competes with for workers and contracts): ranked #6 safest of 10 Semiconductor devices manufact employers in New Hampshire.

Masimo Semiconductor (32 employees, TCR 0.8) among 29 same-industry peers, split at the industry median of 216 employees and a TCR of 0.9

Masimo Semiconductor 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.
