The verdict

Mitsubishi Polysilicon runs at 10% of its industry's injury rate - far safer than the typical Nonferrous metals (except aluminum) smelting and refining, primary workplace, earning a grade A.

Mitsubishi Polysilicon: 0.3 TCR = 10% of Nonferrous metals (except aluminum) smelting and refining, primary BLS 3.3 · 2y Form 300A (see methodology below)

Mitsubishi Polysilicon safety composite

Mitsubishi Polysilicon scores strongest on total case rate (tcr) (safer than 96% 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).
