1,1-Difluoroethene

CAS RN:75-38-7

NFPA Hazard Classification

1,1-Difluoroethene

Flammability: 4
Health: 1Instability: 2
Special: None

Health: 1 (Slight)
Materials that, on exposure, would cause significant irritation, but only minor residual injury, including those requiring the use of an approved air-purifying respirator. These materials are only slightly hazardous to health and only breathing protection is needed.

Flammability: 4 (Extreme)
This degree includes flammable gases, flammable cryogenic materials, pyrophoric liquids, and Class IA flammable liquids. The preferred method of fire attack is to stop the flow of material or to protect exposures while allowing the fire to burn itself out.

Instability: 2 (Moderate)
Materials that can undergo violent chemical changes at elevated temperatures and pressures. This also includes materials that may react violently with water or that may form potentially explosive mixtures with water. In advanced or massive fires involving these materials, fire fighting should be done from a safe distance or from a protected location.
