The verdict

Shamrock Environmental Construction runs at 58% of its industry's injury rate - safer than the typical Channel construction workplace, earning a grade B.

Shamrock Environmental Construction: 1.6 TCR = 58% of Channel construction BLS 2.8 · 3y Form 300A (see methodology below)

Shamrock Environmental Construction safety composite

Shamrock Environmental Construction scores strongest on dart rate (safer than 73% of same-industry peers) and weakest on total case rate (tcr) (safer than 47%), 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 North Carolina alone (the establishments it most directly competes with for workers and contracts): ranked #17 safest of 29 Channel construction employers in North Carolina.

Shamrock Environmental Construction (35 employees, TCR 1.6) among 29 same-industry peers, split at the industry median of 69 employees and a TCR of 1.5

Shamrock Environmental Construction has fewer employees than the Channel construction median and a higher injury rate than the industry's median TCR of 1.5.
