The verdict

Main Office runs at 84% of its industry's injury rate - about level with the typical HVAC (heating, ventilation and air-conditioning) contractors workplace, earning a grade C.

Main Office: 2.4 TCR = 84% of HVAC (heating, ventilation and air-conditioning) contractors BLS 2.8 · 6y Form 300A (see methodology below)

Main Office safety composite

Main Office scores strongest on total case rate (tcr) (safer than 63% of same-industry peers) and weakest on dart rate (safer than 34%), 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).

Main Office has fewer employees than the HVAC (heating, ventilation and air-condi 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.
