The verdict

ON Semiconductor Mountain Top runs at 43% of its industry's injury rate - far safer than the typical Microprocessor chip manufacturing workplace, earning a grade A.

ON Semiconductor Mountain Top: 1.4 TCR = 43% of Microprocessor chip manufacturing BLS 3.3 · 5y Form 300A (see methodology below)

ON Semiconductor Mountain Top safety composite

ON Semiconductor Mountain Top scores strongest on fatalities (safer than 51% of same-industry peers) and weakest on dart rate (safer than 32%), 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).

ON Semiconductor Mountain Top (272 employees, TCR 1.4) among 29 same-industry peers, split at the industry median of 216 employees and a TCR of 0.9

ON Semiconductor Mountain Top has more employees than the Microprocessor chip manufacturing median and a higher injury rate than the industry's median TCR of 0.9. Workforce size and injury rate do not always move together within the same industry -- some of its smaller peers run higher rates than its larger ones, and vice versa.
