Rocky Mountain Mechanical Systems safety composite

Rocky Mountain Mechanical Systems scores strongest on dart rate (safer than 80% of same-industry peers) and weakest on total case rate (tcr) (safer than 38%), 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).

Grade D

More dangerous than peersSafer than peers

Narrower to Colorado alone (the establishments it most directly competes with for workers and contracts): ranked #69 safest of 156 Heating, ventilation and air-c employers in Colorado.

Rocky Mountain Mechanical Systems (28 employees, TCR 4.5) among 29 same-industry peers, split at the industry median of 60 employees and a TCR of 3.3

Rocky Mountain Mechanical Systems has fewer employees than the Heating, ventilation and air-conditionin 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.
