The verdict

General Filters runs at 40% of its industry's injury rate - far safer than the typical Air purification equipment, stationary, manufacturing workplace, earning a grade A.

General Filters: 1.3 TCR = 40% of Air purification equipment, stationary, manufacturing BLS 3.3 · 4y Form 300A (see methodology below)

General Filters safety composite

General Filters scores strongest on total case rate (tcr) (safer than 83% of same-industry peers) and weakest on dart rate (safer than 35%), 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).
