The verdict

Cool Air Mechanical runs at 276% of its industry's injury rate - far more dangerous than the typical Plumbing and heating contractors workplace, earning a grade F.

Cool Air Mechanical: 7.7 TCR = 276% of Plumbing and heating contractors BLS 2.8 · 2y Form 300A (see methodology below)

Cool Air Mechanical safety composite

Cool Air Mechanical scores strongest on fatalities (safer than 51% of same-industry peers) and weakest on total case rate (tcr) (safer than 18%), 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).
