TriMyc Mechanical safety composite

TriMyc Mechanical scores strongest on fatalities (safer than 51% of same-industry peers) and weakest on dart rate (safer than 4%), blended into one 0-100 breakdown against same-industry peers.

This is a per-dimension breakdown, distinct from the single letter grade above it (which weights TCR alone against the BLS industry benchmark).

TriMyc Mechanical has fewer employees than the Plumbing contractors 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.
