The verdict

674 runs at 55% of its industry's injury rate - safer than the typical Drywall and Insulation Contractors workplace, earning a grade B.

674: 1.5 TCR = 55% of Drywall and Insulation Contractors BLS 2.8 · 7y Form 300A (see methodology below)

674 safety composite

674 scores strongest on total case rate (tcr) (safer than 79% of same-industry peers) and weakest on dart rate (safer than 42%), 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).

Narrower to New Hampshire alone (the establishments it most directly competes with for workers and contracts): ranked #4 safest of 15 Drywall and Insulation Contrac employers in New Hampshire.

674 (38 employees, TCR 1.5) among 29 same-industry peers, split at the industry median of 63 employees and a TCR of 3.4

674 has fewer employees than the Drywall and Insulation Contractors median and a lower injury rate than the industry's median TCR of 3.4. 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.
