The verdict

Square One Engineering runs at 72% of its industry's injury rate - safer than the typical Machine shops workplace, earning a grade B.

Square One Engineering: 2.4 TCR = 72% of Machine shops BLS 3.3 · 6y Form 300A (see methodology below)

Square One Engineering safety composite

Square One Engineering scores strongest on dart rate (safer than 75% of same-industry peers) and weakest on fatalities (safer than 50%), 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).

Square One Engineering has fewer employees than the Machine shops median and a lower injury rate than the industry's median TCR of 3.5. 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.
