The verdict

Koch Filter runs at 74% of its industry's injury rate - safer than the typical Filter Manufacturing workplace, earning a grade B.

Koch Filter: 2.5 TCR = 74% of Filter Manufacturing BLS 3.3 · 3y Form 300A (see methodology below)

Koch Filter safety composite

Koch Filter scores strongest on total case rate (tcr) (safer than 64% of same-industry peers) and weakest on dart rate (safer than 42%), 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).
