  • Isoflurane Anesthetic Gas Guidelines | Environmental Health

    Purpose and ApplicabilityHazardsHandling.Spill/Exposure ProceduresIsoflurane gas is commonly used as an inhalation anesthetic in animal research. It is a clear, colorless, volatile liquid at room temperature and pressure. Exposure to second-hand anesthetic gases has been associated with several health concerns and can occur when vapors escape into the work environment during the administration of anesthesia. Since these gases are odorless and have very poor warning properties, there is no indication when an exposure to these substances is occurring. This guideline will focus on the use of isoflurane when administered to research animals. This generic chemical safety guidance describes basic prudent safety practice for handling this chemical in research labs. The principal investigator (PI) or the lab manager is responsible for developing and implementing standard operating procedures (SOPs) for the purchase, storage, and safe handling of this chemical that are specific to the PI’s research.
