Duncan Manufacturing: 1.0 TCR = 31% of Drilling equipment, oil and gas field-type, manufacturing BLS 3.3 · 2y Form 300A (see methodology below)

Duncan Manufacturing safety composite

Duncan Manufacturing scores strongest on total case rate (tcr) (safer than 57% of same-industry peers) and weakest on dart rate (safer than 34%), 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).
