The verdict

Main Office - 01 runs at 112% of its industry's injury rate - about level with the typical Mechanical Contractor workplace, earning a grade C.

Main Office - 01: 3.1 TCR = 112% of Mechanical Contractor BLS 2.8 · 8y Form 300A (see methodology below)

Main Office - 01 safety composite

Main Office - 01 scores strongest on total case rate (tcr) (safer than 52% of same-industry peers) and weakest on dart rate (safer than 41%), 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 - 01 has fewer employees than the Mechanical Contractor 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.
