The verdict

MEAA Mason runs at 42% of its industry's injury rate - far safer than the typical Alternators and generators for internal combustion engines manufacturing workplace, earning a grade A.

MEAA Mason: 2.3 TCR = 42% of Alternators and generators for internal combustion engines manufacturing BLS 5.4 · 2y Form 300A (see methodology below)

MEAA Mason safety composite

MEAA Mason scores strongest on dart rate (safer than 54% of same-industry peers) and weakest on total case rate (tcr) (safer than 41%), 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).
