5.Fire-fighting measures 5.1 Extinguishing media Suitable extinguishing mediaApproach fire from upwind to avoid hazardous vapors & toxic decomp products. Use flooding quantities of water. Do not use carbon dioxide.
5.2 Specific hazards arising from the chemicalSpecial Hazards of Combustion Products: Irritating sulfur dioxide is produced in fire. (USCG, 1999)
5.3 Special protective actions for fire-fightersWear self-contained breathing apparatus for firefighting if necessary.
6.Accidental release measures 6.1 Personal precautions, protective equipment and emergency proceduresUse personal protective equipment. Avoid dust formation. Avoid breathing vapours, mist or gas. Ensure adequate ventilation. Evacuate personnel to safe areas. Avoid breathing dust. For personal protection see section 8.
6.2 Environmental precautionsRemove all ignition sources. Cover the spilled material with dry earth or sand. Sweep spilled substance into covered containers. Carefully collect remainder. Then store and dispose of according to local regulations. Do NOT let this chemical enter the environment. Personal protection: chemical protection suit including self-contained breathing apparatus.
6.3 Methods and materials for containment and cleaning upApproach release from upwind. Keep water away from release. Prompt cleanup & removal are necessary. Shovel dry material into suitable dry container. Control runoff & isolate discharged material for proper disposal.
7.Handling and storage 7.1 Precautions for safe handlingAvoid contact with skin and eyes. Avoid formation of dust and aerosols. Avoid exposure - obtain special instructions before use.Provide appropriate exhaust ventilation at places where dust is formed. For precautions see section 2.2.
7.2 Conditions for safe storage, including any incompatibilitiesSeparated from acids and oxidants. Keep in a well-ventilated room. Dry.Store in a cool, dry, well-ventilated location. Separate from water, acids, & carbon dioxide. Outside or detached storage is preferred. Immediately remove & properly dispose of any spilled material.

10.2 Chemical stabilityUNSTABLE
10.3 Possibility of hazardous reactionsMOIST SODIUM SULFIDE IS SPONTANEOUSLY FLAMMABLE UPON DRYING IN AIR.SODIUM SULFIDE is a white to yellow crystalline material, flammable. Can explode on rapid heating or when shocked. Violent reaction with carbon, charcoal, diazonium salts, N,N-dichloromethylamine, strong oxidizers, water. On contact with acids it liberates highly toxic and flammable hydrogen sulfide gas. When heated to decomposition it emits toxic fumes of sodium oxide, and oxides of sulfur [Bretherick, 5th ed., 1995, p. 1729].
