The verdict

AP Tech runs at 35% of its industry's injury rate - far safer than the typical Semiconductor test equipment manufacturing workplace, earning a grade A.

AP Tech: 1.1 TCR = 35% of Semiconductor test equipment manufacturing BLS 3.3 · 7y Form 300A (see methodology below)

AP Tech safety composite

AP Tech scores strongest on fatalities (safer than 50% of same-industry peers) and weakest on dart rate (safer than 8%), 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).

AP Tech (288 employees, TCR 1.1) among 29 same-industry peers, split at the industry median of 86 employees and a TCR of 0.9

AP Tech has more employees than the Semiconductor test equipment manufacturi 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.
