The verdict

Poet Biorefining: 5.3 TCR = 161% of Ethanol, nonpotable, manufacturing BLS 3.3 · 4y Form 300A (see methodology below)

Poet Biorefining safety composite

Poet Biorefining scores strongest on fatalities (safer than 51% of same-industry peers) and weakest on dart rate (safer than 1%), 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 South Dakota alone (the establishments it most directly competes with for workers and contracts): ranked #18 safest of 23 Ethanol, nonpotable, manufactu employers in South Dakota.

Poet Biorefining (46 employees, TCR 5.3) among 29 same-industry peers, split at the industry median of 47 employees and a TCR of 3.0

Poet Biorefining has fewer employees than the Ethanol, nonpotable, manufacturing median and a higher 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.
