The verdict

Public Works runs at 536% of its industry's injury rate - far more dangerous than the typical Sewage treatment plants or facilities workplace, earning a grade F.

Public Works: 6.4 TCR = 536% of Sewage treatment plants or facilities BLS 1.2 · 3y Form 300A (see methodology below)

Public Works safety composite

Public Works scores strongest on dart rate (safer than 80% of same-industry peers) and weakest on total case rate (tcr) (safer than 33%), 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).

Public Works has fewer employees than the Sewage treatment plants or facilities median and a higher injury rate than the industry's median TCR of 4.4. 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.
