Hazards and Protection.
It is packed in polyethylene containers.
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 a pesticide respirator jointly certified by the mining enforcement and safety administration and by the national institute for occupational safety and health. Wear natural rubber gloves, protective clothing, and goggles.
Wear positive pressure self-contained breathing apparatus (SCBA).
Caution : Explosion potential is high. Containers may explode in heat of fire. Highly toxic phosphorus oxides and chlorides may be emitted when phosphamidon is heated to decomposition. Avoid sources of extreme heat. (Non-Specific -- Organophosphorus Pesticide, Liquid, n.o.s.) Stay upwind; keep out of low areas. Ventilate closed spaces before entering them. Do not touch spilled material; stop leak if you can do so without risk. Use water spray to reduce vapors. Small spills: absorb with sand or other noncombustible absorbent material and place into containers for later disposal. Large spills: dike far ahead of spill for later disposal.
Isomeric mixt stable in neutral and acid media; half-life @ 23 C= 13.8 Days @ pH 7, 2.2 Days @ pH 10 decomp above 160 C e-isomer hydrolyzed by alkali.
Corrosive to iron, tin and aluminum Incompatible with alkaline preparations and should not be mixed with copper oxychloride, captan, folpet or sulfur.
(Non-Specific -- Organophosphorus Pesticide, Liquid, n.o.s.) Stay upwind; keep out of low areas. Move containers from fire area if you can do it without risk. Fight fire from maximum distance. Dike fire control water for later disposal; do not scatter the material.(Non-Specific -- Organophosphorus Pesticide, Liquid, n.o.s.) This material may burn, but does not ignite readily. For small fires, use dry chemical, carbon dioxide, water spray, or foam. For large fires, use water spray, fog, or foam.
Combustible material: may burn but does not ignite readily.
Containers may explode when heated.
Fire may produce irritating, corrosive and/or toxic gases.
Fever, low heart rate and abnormally low blood pressure, or rapid heart rate and elevated blood pressure may occur. Headache, dizziness, muscle spasms and profound weakness are common. Alterations of level of consciousness, anxiety, paralysis, seizures and coma may occur. Seizures may be more common in children.
Vomiting, hypersalivation, diarrhea, fecal incontinence and abdominal pain may occur.
Dyspnea, rales, bronchorrhea, bronchospasm, or tachypnea may be noted. Noncardiogenic pulmonary edema may occur in severe cases. Chemical pneumonitis may be seen.
Sweating is a consistent but not universal sign.
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. Immediately flush with running water for at least 20 minutes. For minor skin contact, avoid spreading material on unaffected skin.
Immediately flush with running water for at least 20 minutes.
