The verdict

Zymergen runs at 150% of its industry's injury rate - more dangerous than the typical Biotechnology research and development laboratories or services workplace, earning a grade D.

Zymergen: 0.8 TCR = 150% of Biotechnology research and development laboratories or services BLS 0.5 · 6y Form 300A (see methodology below)

Zymergen safety composite

Zymergen scores strongest on dart rate (safer than 76% of same-industry peers) and weakest on total case rate (tcr) (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).

Zymergen (491 employees, TCR 0.8) among 29 same-industry peers, split at the industry median of 296 employees and a TCR of 0.8

Zymergen has more employees than the Biotechnology research and development l 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.
