The verdict

Ampere Computing LLC runs at 5% of its industry's injury rate - far safer than the typical Semiconductor devices manufacturing workplace, earning a grade A.

Ampere Computing LLC: 0.2 TCR = 5% of Semiconductor devices manufacturing BLS 3.3 · 2y Form 300A (see methodology below)

Ampere Computing LLC safety composite

Ampere Computing LLC scores strongest on total case rate (tcr) (safer than 93% 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).

Ampere Computing LLC (609 employees, TCR 0.2) among 29 same-industry peers, split at the industry median of 216 employees and a TCR of 0.9

Ampere Computing LLC has more 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.
