Hazards and Protection.
Keep containers tightly closed in a well ventilated area away from food products. Keep away from heat and water. Store at in area away from seed fertilizers, insecticides or fungicides.
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 gloves, boots and goggles.
Wear positive pressure self-contained breathing apparatus (SCBA).
Keep material out of water sources and sewers. Build dikes to contain flow as necessary. Land spill: Dig a pit, pond, lagoon, holding area to contain liquid or solid material. Cover solids with a plastic sheet to prevent dissolving in rain or fire fighting water. Water spill: If dissolved, in region of 10 ppm or greater concentration, apply activated carbon at ten times the spilled amount. Use mechanical dredges or lifts to remove immobilized masses of pollutants and precipitates.
It is resistant to oxidation and hydrolysis under normal conditions. Resistant to acid and strong alkali.
Reacts as a weak acid to neutralize bases, both organic (for example, the amines) and inorganic Reacts with cyanide salts in the presence of moisture to generate gaseous hydrogen cyanide May react if moist with sulfites, nitrites, thiosulfates (to give H2S and SO3), dithionites (SO2), to generate flammable and/or toxic gases and heat.
Extinguish fire using agent suitable for type of surrounding fire. (Material itself does not burn or burns with difficulty.)
Fire may produce irritating, corrosive and/or toxic gases.
Dicamba was shown not to be teratogenic in rabbits and rats tested. When tested in rats over 3 generations, no reduction in reproduction capacity was noted. <br>Lactating cows exposed to dicamba excreted about 0.02% in milk.
Vomiting, anorexia, and weight loss have been reported with human exposure to the dimethylamine salt.
Cyanosis and dyspnea were noted in experimental animals poisoned by dicamba.
Dicamba is irritating to the skin. It was shown to be a moderate skin sensitizer in guinea pigs. When injected subcutaneously in animals, necrosis or fluid filled abscesses were noted.
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.
Wash with ample water.
Flush with water; obtain medical attention.
