The verdict

Corporate Office runs at 74% of its industry's injury rate - safer than the typical Heating, ventilation and air-conditioning (HVAC) contractors workplace, earning a grade B.

Corporate Office: 2.1 TCR = 74% of Heating, ventilation and air-conditioning (HVAC) contractors BLS 2.8 · 8y Form 300A (see methodology below)

Corporate Office safety composite

Corporate Office scores strongest on dart rate (safer than 80% of same-industry peers) and weakest on fatalities (safer than 1%), 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).
