The verdict

A.M. Concrete runs at 70% of its industry's injury rate - safer than the typical Sidewalk, public, construction workplace, earning a grade B.

A.M. Concrete: 2.0 TCR = 70% of Sidewalk, public, construction BLS 2.8 · 2y Form 300A (see methodology below)

A.M. Concrete safety composite

A.M. Concrete scores strongest on dart rate (safer than 81% of same-industry peers) and weakest on fatalities (safer than 53%), 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.M. Concrete (28 employees, TCR 2.0) among 29 same-industry peers, split at the industry median of 69 employees and a TCR of 3.0

A.M. Concrete has fewer employees than the Sidewalk, public, construction median and a lower injury rate than the industry's median TCR of 3.0. 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.
