The verdict

Block MEMS, LLC runs at 0% of its industry's injury rate - about level with the typical Photonics research and development services workplace, earning a grade C.

Block MEMS, LLC: 0.0 TCR = 0% of Photonics research and development services BLS 0.5 · 3y Form 300A (see methodology below)

Block MEMS, LLC safety composite

Block MEMS, LLC scores strongest on total case rate (tcr) (safer than 100% of same-industry peers) and weakest on fatalities (safer than 50%), 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).
