The verdict

Detroit Aggregate runs at 59% of its industry's injury rate - safer than the typical Ready-Mix Concrete Manufacturing workplace, earning a grade B.

Detroit Aggregate: 1.9 TCR = 59% of Ready-Mix Concrete Manufacturing BLS 3.3 · 2y Form 300A (see methodology below)

Detroit Aggregate safety composite

Detroit Aggregate scores strongest on total case rate (tcr) (safer than 82% 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).
