The verdict

Corval Group runs at 11% of its industry's injury rate - far safer than the typical Mechanical contractors workplace, earning a grade A.

Corval Group: 0.3 TCR = 11% of Mechanical contractors BLS 2.8 · 8y Form 300A (see methodology below)

Corval Group safety composite

Corval Group scores strongest on total case rate (tcr) (safer than 98% 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).

Corval Group has more employees than the Mechanical contractors median and a lower 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.
