SECTION 5: Fire Fighting Measures Flash Point:no data Autoignition Temperature:pyrophoric Explosion Limits:pyrophoric Extinguishing Medium:carbon dioxide, dry powder or foam If this product is involved in a fire, fire fighters should be equipped with a NIOSH approved positive pressure Special Fire Fighting Procedures: self-contained breathing apparatus and full protective clothing. Hazardous Combustion andIf involved in a fire, this material may emit corrosive organic fumes and vapors of phosphorus pentoxide. Decomposion Products: Unusual Fire or Explosion Hazards: Spontaneously flammable in air, especially in contact with organic matter such as paper or cloth. SECTION 6: Accidental Release Measures The material may ignite spontaneously in air. Avoid static discharge. Burning material may release toxic fumes. In case of poor ventilation, leave the area unless fitted with a self-contained breathing apparatus. Small Spill and Leak Procedures: spills can be smothered with ground limestone, sodium bicarbonate or other suitable adsorbent, swept up and held in a closed container. SECTION 7: Handling and Storage Store in a tightly sealed container under an inert atmosphere of nitrogen or argon. Keep away from heat. Handling and Storage:Material should be transferred under an inert atmosphere of nitrogen or argon in an efficient fume hood. Fire may occur in empty container and transfer lines. SECTION 8: Exposure Controls and Personal Protection Eye Protection:Always wear approved safety glasses when handling a chemical substance in the laboratory. Skin Protection:Wear protective clothing and gloves. Ventilation:Handle the material in an efficient fume hood. If ventilation is not available a respirator should be worn. The use of respirators requires a Respirator Respirator: Protection Program to be in compliance with 29 CFR 1910.134. Ventilation:Handle the material in an efficient fume hood. Additional Protection:No additional protection required. SECTION 9: Physical and Chemical Properties Color and Form:colorless to yellow liq.
