                First Aid Measures

                Ingestion
                Never give anything by mouth to an unconscious person. Get medical aid. Do NOT induce vomiting. If conscious and alert, rinse mouth and drink 2-4 cupfuls of milk or water.
                Inhalation
                Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid.
                Skin
                Get medical aid. Flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. Wash clothing before reuse.
                Eyes
                Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid.

                Handling and Storage

                Storage
                Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances. Store protected from moisture.
                Handling
                Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Use with adequate ventilation. Minimize dust generation and accumulation. Avoid contact with eyes, skin, and clothing. Keep container tightly closed. Avoid ingestion and inhalation.

                Hazards Identification

                Inhalation
                The toxicological properties of this substance have not been fully investigated. Inhalation of dust may cause respiratory tract irritation. Can produce delayed pulmonary edema. Causes irritation of the mucous membrane and upper respiratory tract.
                Skin
                Causes skin irritation.
                Eyes
                Causes eye irritation. May cause chemical conjunctivitis.
                Ingestion
                May cause gastrointestinal irritation with nausea, vomiting and diarrhea. The toxicological properties of this substance have not been fully investigated.
                Hazards
                During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion.

                Exposure Controls/Personal Protection

                Personal Protection
                Eyes: Wear appropriate protective eyeglasses or chemical safety goggles as described by OSHA's eye and face protection regulations in 29 CFR 1910.133 or European Standard EN166. Skin: Wear appropriate protective gloves to prevent skin exposure. Clothing: Wear appropriate protective clothing to prevent skin exposure.
                Respirators
                A respiratory protection program that meets OSHA's 29 CFR 1910.134 and ANSI Z88.2 requirements or European Standard EN 149 must be followed whenever workplace conditions warrant a respirator's use.
                Exposure Effects
                Effects may be delayed.
                Poison Class

                Fire Fighting Measures

                Fire Fighting
                Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. This material in sufficient quantity and reduced particle size is capable of creating a dust explosion. Extinguishing media: Use agent most appropriate to extinguish fire. In case of fire use water spray, dry chemical, carbon dioxide, or appropriate foam.

                Accidental Release Measures

                Small spills/leaks
                Vacuum or sweep up material and place into a suitable disposal container. Clean up spills immediately, using the appropriate protective equipment. Avoid generating dusty conditions. Provide ventilation.

                Stability and Reactivity

                Stability
                Stable at room temperature in closed containers under normal storage and handling conditions.
                Incompatibilities
                Strong oxidizing agents, ammonia, magnesium, sodium, calcium, moisture.
                Decomposition
                Phosphine, oxides of phosphorus, irritating and toxic fumes and gases.
                Combustion Products
                During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion.
