Machine Dynamics & Engineering Inc: 3.0 TCR = 90% of Pressure control valves (except fluid power), industrial-type, manufacturing BLS 3.3 · 4y Form 300A (see methodology below)

Machine Dynamics & Engineering Inc safety composite

Machine Dynamics & Engineering Inc scores strongest on fatalities (safer than 50% of same-industry peers) and weakest on dart rate (safer than 20%), 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).
