1,4-Dioxane

CAS RN: 123-91-1

NFPA Hazard Classification

1,4-Dioxane

Flammability: 3
Health: 2Instability: 1
Special: None

Health: 2 (Moderate)
Materials that, on intense or continued (but not chronic) exposure, could cause temporary incapacitation or possible residual injury, including those requiring the use of respiratory protective equipment that has an independent air supply. These materials are hazardous to health, but areas may be entered freely if personnel are provided with full-face mask self-contained breathing apparatus that provides complete eye protection.

Flammability: 3 (Serious)
This degree includes Class IB and IC flammable liquids and materials that can be easily ignited under almost all normal temperature conditions. Water may be ineffective in controlling or extinguishing fires in such materials.

Instability: 1 (Slight)
This degree includes materials that are normally stable, but that may become unstable at elevated temperatures and pressures and materials that will react with water with some release of energy, but not violently. Fires involving these materials should be approached with caution.
