The verdict

Mapleton Foundry runs at 89% of its industry's injury rate - about level with the typical Iron foundries workplace, earning a grade C.

Mapleton Foundry: 3.0 TCR = 89% of Iron foundries BLS 3.3 · 5y Form 300A (see methodology below)

Mapleton Foundry safety composite

Mapleton Foundry scores strongest on total case rate (tcr) (safer than 83% of same-industry peers) and weakest on fatalities (safer than 2%), 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).
