The verdict

Air-Vol Block runs at 38% of its industry's injury rate - far safer than the typical Concrete Block Manufacturing workplace, earning a grade A.

Air-Vol Block: 1.2 TCR = 38% of Concrete Block Manufacturing BLS 3.3 · 2y Form 300A (see methodology below)

Air-Vol Block safety composite

Air-Vol Block 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).
