The verdict

HMNBM04 runs at 20% of its industry's injury rate - far safer than the typical Search, detection, navigation, guidance, aeronautical, and nautical systems and instrument manufacturing workplace, earning a grade A.

HMNBM04 safety composite

HMNBM04 scores strongest on dart rate (safer than 75% of same-industry peers) and weakest on fatalities (safer than 50%), 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).

HMNBM04 (310 employees, TCR 0.7) among 29 same-industry peers, split at the industry median of 207 employees and a TCR of 0.7

HMNBM04 has more employees than the Search, detection, navigation, guidance, median and a lower injury rate than the industry's median TCR of 0.7. 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.
