The verdict

CA257 runs at 296% of its industry's injury rate - far more dangerous than the typical Other Building Materials workplace, earning a grade F.

CA257: 10.1 TCR = 296% of Other Building Materials BLS 3.4 · 4y Form 300A (see methodology below)

CA257 safety composite

CA257 scores strongest on fatalities (safer than 50% of same-industry peers) and weakest on dart rate (safer than 0%), 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).

CA257 (33 employees, TCR 10.1) among 29 same-industry peers, split at the industry median of 35 employees and a TCR of 5.2

CA257 has fewer employees than the Other Building Materials median and a higher injury rate than the industry's median TCR of 5.2. 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.
