Hazards and Protection.
Protect from moist air - will react to produce highly toxic phosphine.
All chemicals should be considered hazardous. Avoid direct physical contact. Use appropriate, approved safety equipment. Untrained individuals should not handle this chemical or its container. Handling should occur in a chemical fume hood.
Wear appropriate chemical protective clothing.
Wear positive pressure self-contained breathing apparatus.
Do not use water. Keep sparks, flames, and other sources of ignition away. Keep material out of water sources and sewers. Keep material dry.
Can react vigorously with oxidizing materials Incompatible with oxidizers such as atmospheric oxygen Incompatible with acids, particularly oxidizing acids.
Do not extinguish fire unless flow can be stopped. Do not use water. Use graphite, soda ash, powdered sodium chloride, or suitable dry powder.
Produce flammable and toxic gases on contact with water. May ignite on contact with water or moist air. Some react vigorously or explosively on contact with water. May be ignited by heat, sparks or flames. May re-ignite after fire is extinguished. Some are transported in highly flammable liquids. Runoff may create fire or explosion hazard.
Fire will produce irritating, corrosive and/or toxic gases.
The toxological properties of this substance have not been fully investigated.
Highly toxic: contact with water produces toxic gas, may be fatal if inhaled. Inhalation or contact with vapors, substance, or decomposition products may cause severe injury or death.
May cause burns.
Seek medical assistance.
Move victim to fresh air. Apply artificial respiration if victim is not breathing. Do not use mouth-to-mouth method if victim ingested or inhaled the substance; induce artificial respiration with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device. Administer oxygen if breathing is difficult.
Remove and isolate contaminated clothing and shoes. In case of contact with substance, wipe from skin immediately. Flush with running water for at least 20 minutes.
