Cabot Microelectronics Corporation - 500 runs at 11% of its industry's injury rate - far safer than the typical Semiconductor devices manufacturing workplace, earning a grade A.

Cabot Microelectronics Corporation - 500: 0.4 TCR = 11% of Semiconductor devices manufacturing BLS 3.3 · 4y Form 300A (see methodology below)

Cabot Microelectronics Corporation - 500 safety composite

Cabot Microelectronics Corporation - 500 scores strongest on total case rate (tcr) (safer than 80% 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).
