The verdict

Chesapeake Optical Laboratory runs at 35% of its industry's injury rate - far safer than the typical Lenses, ophthalmic, manufacturing workplace, earning a grade A.

Chesapeake Optical Laboratory: 1.1 TCR = 35% of Lenses, ophthalmic, manufacturing BLS 3.3 · 3y Form 300A (see methodology below)

Chesapeake Optical Laboratory safety composite

Chesapeake Optical Laboratory scores strongest on total case rate (tcr) (safer than 75% of same-industry peers) and weakest on dart rate (safer than 40%), 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).
