The verdict

Microvention runs at 33% of its industry's injury rate - far safer than the typical Instruments, mechanical microsurgical, manufacturing workplace, earning a grade A.

Microvention: 1.1 TCR = 33% of Instruments, mechanical microsurgical, manufacturing BLS 3.3 · 2y Form 300A (see methodology below)

Microvention safety composite

Microvention scores strongest on total case rate (tcr) (safer than 62% 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).
