The verdict

Engineering runs at 113% of its industry's injury rate - about level with the typical Municipal Government workplace, earning a grade C.

Engineering: 3.6 TCR = 113% of Municipal Government BLS 3.2 · 7y Form 300A (see methodology below)

Engineering safety composite

Engineering scores strongest on total case rate (tcr) (safer than 53% of same-industry peers) and weakest on dart rate (safer than 48%), 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).

Engineering (56 employees, TCR 3.6) among 23 same-industry peers, split at the industry median of 82 employees and a TCR of 4.6

Engineering has fewer employees than the Municipal Government median and a lower injury rate than the industry's median TCR of 4.6. 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.
