The verdict

Protomet Corporation runs at 137% of its industry's injury rate - more dangerous than the typical Machine shops workplace, earning a grade D.

Protomet Corporation: 4.5 TCR = 137% of Machine shops BLS 3.3 · 2y Form 300A (see methodology below)

Protomet Corporation safety composite

Protomet Corporation scores strongest on fatalities (safer than 50% of same-industry peers) and weakest on dart rate (safer than 33%), 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).

Grade D

More dangerous than peersSafer than peers

Narrower to Tennessee alone (the establishments it most directly competes with for workers and contracts): ranked #8 safest of 20 Machine shops employers in Tennessee.

Protomet Corporation (104 employees, TCR 4.5) among 29 same-industry peers, split at the industry median of 48 employees and a TCR of 3.5

Protomet Corporation has more employees than the Machine shops median and a higher 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.
