Means of Extinction...... EDTA does not burn or burns with difficulty. Use extinguishing media suitable for surrounding fire, dry chemical, CO2, water spray or regular foam. Flash Point..... >100ºC (closed cup). Auto-ignition Temperature. >200ºC.

of 7 Upper Flammable Limit.. Lower Flammable Limit....... Hazardous Combustible Products... Special Fire Fighting Procedures... When heated under fire conditions, tetrasodium ethylenediaminetetraacetate gives off carbon monoxide, carbon dioxide, irritating/toxic nitrogen oxides and sodium oxides. When exposed to fire or excessive heat for a sufficient period of time, tetrasodium ethylenediaminetetraacetate will decompose causing a rapid build-up of pressure inside closed containers. Containers may rupture explosively with a sudden release of large amounts of toxic and irritating gases. Wear NIOSH-approved self-contained breathing apparatus and protective clothing. Explosion Hazards... Section 06 - Accidental Release Measures Leak / Spill....... Evacuate and ventilate the area. Swwp up and place in container for disposal. Wear appropriate personal protective equipment. Only enter area with PPE. Stop or reduce leak if safe to do so. Prevent material from entering sewers. Flush with water to remove any residue. Deactivating Materials....... Section 07 - Handling and Storage Handling Procedures...... Use proper equipment for lifting and transporting all containers. Use sensible industrial hygiene and housekeeping practices. Wash thoroughly after handling. Avoid all situations that could lead to harmful exposure. Storage Requirements........ Store in a cool place away from heated areas, sparks, and flame. Store in a well ventilated area. Store away from incompatible materials. Do not add any other material to the container. Do not wash down the drain. Do not breathe dust. Keep container tightly closed and dry. Manipulate in a well ventilated area or under an adequate fume hood. Avoid raising dust. Handle and open container with care. Minimize dust generation and exposure - use dust mask or appropriate protection. This product must be manipulated by qualified personnel.
