IBWC safety composite

IBWC scores strongest on total case rate (tcr) (safer than 90% 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).

IBWC has fewer employees than the Sewage treatment plants or facilities median and a lower 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.
