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.
Physical and Chemical Properties: FGA General Characteristics
| Vapor Pressure | Extremely low vapor pressure; 5 to 10 times lower than VX |
| Density (vapor) | Heavier than air |
| Skin Absorption | Easily absorbed by the skin |
| Aqueous Solubility | Highly water soluble |
| Soluble in | Acetone, benzene, ethanol, methanol, chloroform, saline |
| Flash Point | Greater than 300 degrees Fahrenheit |
| Persistence | Can remain on environmental surfaces for days or even many months, if not decontaminated |
