The verdict

MIS runs at 29% of its industry's injury rate - far safer than the typical Cellular phone tower construction workplace, earning a grade A.

MIS: 0.8 TCR = 29% of Cellular phone tower construction BLS 2.8 · 2y Form 300A (see methodology below)

MIS safety composite

MIS scores strongest on total case rate (tcr) (safer than 80% of same-industry peers) and weakest on dart rate (safer than 44%), 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%).

MIS has more employees than the Cellular phone tower construction median and a lower injury rate than the industry's median TCR of 2.0. 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.
