   TechCrunch reported that as many as 40 workers may have been exposed according to OSHA, though Zoox disputes the number. The exact gas responsible remained unclear—ER doctors told affected workers their symptoms were consistent with carbon monoxide, but Zoox later told TechCrunch it detected no battery damage or hydrogen sulfide. The article attributed retaliation concerns for workers requesting anonymity.

   “Multiple Zoox test drivers in Atlanta -- as many as 40, though Zoox says fewer -- spent August reporting toxic gas exposure symptoms. OSHA opened an inquiry and told Zoox to investigate.”
