AC Corporation - GSO: 2.5 TCR = 88% of Air system balancing and testing BLS 2.8 · 3y Form 300A (see methodology below)

AC Corporation - GSO safety composite

AC Corporation - GSO scores strongest on total case rate (tcr) (safer than 61% of same-industry peers) and weakest on fatalities (safer than 51%), 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).
