The verdict

Hill manufacturing runs at 45% of its industry's injury rate - far safer than the typical Machine shops workplace, earning a grade A.

Hill manufacturing: 1.5 TCR = 45% of Machine shops BLS 3.3 · 2y Form 300A (see methodology below)

Hill manufacturing safety composite

Hill manufacturing scores strongest on total case rate (tcr) (safer than 82% of same-industry peers) and weakest on dart rate (safer than 24%), 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%).

Where Hill manufacturing falls in its industry

1,821 Machine shops establishments

Safer than 82% of graded establishments in this industry, whose median TCR is 3.5.

Grade A

More dangerous than peersSafer than peers

Narrower to Oklahoma alone (the establishments it most directly competes with for workers and contracts): ranked #2 safest of 17 Machine shops employers in Oklahoma.

Hill manufacturing (30 employees, TCR 1.5) among 29 same-industry peers, split at the industry median of 48 employees and a TCR of 3.5

Hill manufacturing has fewer employees than the Machine shops median and a lower injury rate than the industry's median TCR of 3.5. 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.
