The verdict

NKA runs at 112% of its industry's injury rate - about level with the typical Electromedical equipment manufacturing workplace, earning a grade C.

NKA: 3.7 TCR = 112% of Electromedical equipment manufacturing BLS 3.3 · 4y Form 300A (see methodology below)

NKA safety composite

NKA scores strongest on dart rate (safer than 52% of same-industry peers) and weakest on total case rate (tcr) (safer than 12%), 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).

NKA (342 employees, TCR 3.7) among 29 same-industry peers, split at the industry median of 186 employees and a TCR of 1.1

NKA has more employees than the Electromedical equipment manufacturing median and a higher injury rate than the industry's median TCR of 1.1. 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.
