The verdict

Main Office - 01 runs at 92% of its industry's injury rate - about level with the typical Manufacturing workplace, earning a grade C.

Main Office - 01: 3.0 TCR = 92% of Manufacturing BLS 3.3 · 7y Form 300A (see methodology below)

Main Office - 01 safety composite

Main Office - 01 scores strongest on total case rate (tcr) (safer than 62% of same-industry peers) and weakest on dart rate (safer than 17%), 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).

More dangerous than peersSafer than peers

Narrower to Iowa alone (the establishments it most directly competes with for workers and contracts): ranked #4 safest of 11 Manufacturing employers in Iowa.

Main Office - 01 (636 employees, TCR 3.0) among 29 same-industry peers, split at the industry median of 83 employees and a TCR of 4.1

Main Office - 01 has more employees than the Manufacturing median and a lower injury rate than the industry's median TCR of 4.1. 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.
