The verdict

Allied Mechanical runs at 359% of its industry's injury rate - far more dangerous than the typical Machine shops workplace, earning a grade F.

Allied Mechanical: 11.9 TCR = 359% of Machine shops BLS 3.3 · 5y Form 300A (see methodology below)

Allied Mechanical safety composite

Allied Mechanical scores strongest on fatalities (safer than 50% of same-industry peers) and weakest on total case rate (tcr) (safer than 4%), 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).

Narrower to California alone (the establishments it most directly competes with for workers and contracts): ranked #119 safest of 126 Machine shops employers in California.

Allied Mechanical (132 employees, TCR 11.9) among 29 same-industry peers, split at the industry median of 48 employees and a TCR of 3.5

Allied Mechanical 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.
