Recommended Best Practices to Minimize Emergency Responder Exposures to Synthetic Opioids, Including Fentanyl and Fentanyl Analogs [open pdf - 1MB]
"Increased illicit use of opioids, including synthetic opioids such as fentanyl and its analog carfentanil, is a source of increased risk to responders. Most routine encounters between patients or detainees and emergency medical services ( EMS ) or law enforcement personnel do not present a significant threat of toxic exposure. Synthetic opioids are highly toxic organic solids that have been found as powders, pills, liquids, and nasal sprays. While specific exposure standards do not exist, the pharmaceutical industry uses an estimated occupational inhalation exposure limit of 0.0001 mg/m 3 for fentanyl. A secondary dermal hazard exists if there is direct skin contact with large, bulk amounts of concentrated threat materials."
