The verdict

A-1 Air runs at 497% of its industry's injury rate - far more dangerous than the typical Air-conditioning system (except window) installation workplace, earning a grade F.

A-1 Air: 13.9 TCR = 497% of Air-conditioning system (except window) installation BLS 2.8 · 2y Form 300A (see methodology below)

A-1 Air safety composite

A-1 Air scores strongest on dart rate (safer than 80% of same-industry peers) and weakest on total case rate (tcr) (safer than 4%), 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).

A-1 Air 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.
