Exposure Limits

  • The U.S. government has no occupational exposure data on FGAs. There are no established occupational exposure limits, Permissible Exposure Limits, or Acute Exposure Guideline Levels for FGAs, so all precautions must be taken to prevent any exposure. The recommendations in this guide are based on the reported toxicity and the chemical and physical properties of FGAs.
