The verdict

Charleston Corporation: 4.9 TCR = 150% of Tanks, storage, plastics or fiberglass, manufacturing BLS 3.3 · 3y Form 300A (see methodology below)

Charleston Corporation safety composite

Charleston Corporation scores strongest on dart rate (safer than 54% of same-industry peers) and weakest on total case rate (tcr) (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 D

More dangerous than peersSafer than peers

Narrower to Indiana alone (the establishments it most directly competes with for workers and contracts): ranked #92 safest of 143 Tanks, storage, plastics or fi employers in Indiana.

Charleston Corporation (67 employees, TCR 4.9) among 29 same-industry peers, split at the industry median of 101 employees and a TCR of 3.5

Charleston Corporation has fewer employees than the Tanks, storage, plastics or fiberglass, 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.
