The verdict

Micron Boise Site runs at 5% of its industry's injury rate - far safer than the typical Semiconductor memory chips manufacturing workplace, earning a grade A.

Micron Boise Site: 0.2 TCR = 5% of Semiconductor memory chips manufacturing BLS 3.3 · 4y Form 300A (see methodology below)

Micron Boise Site safety composite

Micron Boise Site scores strongest on total case rate (tcr) (safer than 93% of same-industry peers) and weakest on fatalities (safer than 51%), 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).
