Trimethyl Phosphite

CAS RN:121-45-9

NFPA Hazard Classification

Trimethyl Phosphite

Flammability: 3
Health: 1Instability: 1
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: 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.
