The verdict

ZOLL Medical runs at 28% of its industry's injury rate - far safer than the typical Electromedical equipment manufacturing workplace, earning a grade A.

ZOLL Medical: 0.9 TCR = 28% of Electromedical equipment manufacturing BLS 3.3 · 5y Form 300A (see methodology below)

ZOLL Medical safety composite

ZOLL Medical scores strongest on dart rate (safer than 56% 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).

ZOLL Medical has more employees than the Electromedical equipment manufacturing median and a lower injury rate than the industry's median TCR of 1.1.
