The document summarizes personal breathing zone exposure monitoring conducted for isoflurane, an anesthetic agent, at a research facility in India. Air sampling found that exposures for surgeons, investigators, and support staff were all less than 10% of the UK workplace exposure limit when using induction chambers, nose hoses, and prototype local exhaust ventilation controls. Recommendations included improving the local exhaust ventilation and adding backup power to prevent releases during power outages. The monitoring found the engineering controls effectively reduced exposures below limits.
