The verdict

DynaGrid runs at 6% of its industry's injury rate - far safer than the typical Poured Concrete Foundation workplace, earning a grade A.

DynaGrid: 0.2 TCR = 6% of Poured Concrete Foundation BLS 2.8 · 2y Form 300A (see methodology below)

DynaGrid safety composite

DynaGrid scores strongest on total case rate (tcr) (safer than 100% of same-industry peers) and weakest on fatalities (safer than 51%), 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).

Benchmarked live against every credibly-rated employer in the same NAICS industry code in the current OSHA extract (a segment must have at least 8 rated peers to benchmark). Not a legal or compliance determination; PlainSafetyScore's own weighting (TCR 40%, DART 35%, fatalities 25%).

Grade A

More dangerous than peersSafer than peers

Narrower to Texas alone (the establishments it most directly competes with for workers and contracts): ranked #2 safest of 125 Poured Concrete Foundation employers in Texas.

DynaGrid (244 employees, TCR 0.2) among 29 same-industry peers, split at the industry median of 64 employees and a TCR of 3.8

DynaGrid has more employees than the Poured Concrete Foundation median and a lower injury rate than the industry's median TCR of 3.8. 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.
