The verdict

Micro Lithography Inc. runs at 128% of its industry's injury rate - more dangerous than the typical Semiconductor devices manufacturing workplace, earning a grade D.

Micro Lithography Inc.: 4.2 TCR = 128% of Semiconductor devices manufacturing BLS 3.3 · 2y Form 300A (see methodology below)

Micro Lithography Inc. safety composite

Micro Lithography Inc. scores strongest on fatalities (safer than 51% of same-industry peers) and weakest on total case rate (tcr) (safer than 4%), 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).

Micro Lithography Inc. (54 employees, TCR 4.2) among 29 same-industry peers, split at the industry median of 216 employees and a TCR of 0.9

Micro Lithography Inc. has fewer employees than the Semiconductor devices 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.
