The verdict

Poet Biorefining- Corning runs at 70% of its industry's injury rate - safer than the typical Ethanol, nonpotable, manufacturing workplace, earning a grade B.

Poet Biorefining- Corning: 2.3 TCR = 70% of Ethanol, nonpotable, manufacturing BLS 3.3 · 2y Form 300A (see methodology below)

Poet Biorefining- Corning safety composite

Poet Biorefining- Corning scores strongest on total case rate (tcr) (safer than 65% of same-industry peers) and weakest on dart rate (safer than 32%), 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 B

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 49 Ethanol, nonpotable, manufactu employers in Iowa.

Poet Biorefining- Corning (43 employees, TCR 2.3) among 29 same-industry peers, split at the industry median of 47 employees and a TCR of 3.0

Poet Biorefining- Corning has fewer employees than the Ethanol, nonpotable, manufacturing median and a lower injury rate than the industry's median TCR of 3.0. 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.
