The verdict

Main Office runs at 136% of its industry's injury rate - more dangerous than the typical Mechanical contractors workplace, earning a grade D.

Main Office: 3.8 TCR = 136% of Mechanical contractors BLS 2.8 · 2y Form 300A (see methodology below)

Main Office safety composite

Main Office scores strongest on fatalities (safer than 51% of same-industry peers) and weakest on total case rate (tcr) (safer than 45%), 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 more employees than the Mechanical 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.
