The verdict

Main Office runs at 233% of its industry's injury rate - far more dangerous than the typical Concrete pumping (i.e., placement) workplace, earning a grade F.

Main Office: 6.5 TCR = 233% of Concrete pumping (i.e., placement) BLS 2.8 · 2y Form 300A (see methodology below)

Main Office safety composite

Main Office scores strongest on fatalities (safer than 51% of same-industry peers) and weakest on total case rate (tcr) (safer than 25%), 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).

Safer than 25% of graded establishments in this industry, whose median TCR is 3.8.

Grade F

More dangerous than peersSafer than peers

Narrower to Iowa alone (the establishments it most directly competes with for workers and contracts): ranked #17 safest of 32 Concrete pumping (i.e., placem employers in Iowa.

Main Office (32 employees, TCR 6.5) among 29 same-industry peers, split at the industry median of 64 employees and a TCR of 3.8

Main Office has fewer employees than the Concrete pumping (i.e., placement) median and a higher injury rate than the industry's median TCR of 3.8. 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.
