LAAC1 safety composite

LAAC1 scores strongest on fatalities (safer than 51% of same-industry peers) and weakest on dart rate (safer than 17%), 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).

LAAC1 has fewer employees than the Air-conditioning system (except window) median and a higher injury rate than the industry's median TCR of 3.3. 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.
