The verdict

HHO runs at 48% of its industry's injury rate - far safer than the typical Engineering research and development laboratories or services workplace, earning a grade A.

HHO: 0.2 TCR = 48% of Engineering research and development laboratories or services BLS 0.5 · 8y Form 300A (see methodology below)

HHO safety composite

HHO scores strongest on total case rate (tcr) (safer than 81% 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).

HHO (280 employees, TCR 0.2) among 29 same-industry peers, split at the industry median of 159 employees and a TCR of 0.8

HHO has more employees than the Engineering research and development lab median and a lower injury rate than the industry's median TCR of 0.8. 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.
