The verdict

Service Department runs at 51% of its industry's injury rate - safer than the typical Heating, ventilation and air-conditioning (HVAC) contractors workplace, earning a grade B.

Service Department: 1.4 TCR = 51% of Heating, ventilation and air-conditioning (HVAC) contractors BLS 2.8 · 2y Form 300A (see methodology below)

Service Department safety composite

Service Department scores strongest on total case rate (tcr) (safer than 79% of same-industry peers) and weakest on dart rate (safer than 31%), 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 B

More dangerous than peersSafer than peers

Narrower to Maryland alone (the establishments it most directly competes with for workers and contracts): ranked #30 safest of 121 Heating, ventilation and air-c employers in Maryland.

Service Department (40 employees, TCR 1.4) among 29 same-industry peers, split at the industry median of 60 employees and a TCR of 3.3

Service Department has fewer employees than the Heating, ventilation and air-conditionin 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.
