Timberline Mechanical Systems safety composite

Timberline Mechanical Systems scores strongest on fatalities (safer than 51% of same-industry peers) and weakest on total case rate (tcr) (safer than 15%), 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).

Timberline Mechanical Systems has fewer employees than the Heating 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.
