Hazards and Protection.
Keep containers tightly closed in a well ventilated area away from food products. Keep away from heat and water.
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 protective gloves, clothing and goggles.
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: Neutralize with agricultural lime (CaO), crushed limestone (CaCO3), or sodium bicarbonate (NaHCO3). If dissolved, in region of 10 ppm or greater concentration, apply activated carbon at ten times the spilled amount. Remove trapped material with suction hoses. Use mechanical dredges or lifts to remove immobilized masses of pollutants and precipitates.
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.

Chronic lead exposure may cause elevated blood pressure and gout. In young children, developmental defects, including learning disabilities and behavioral abnormalities, can occur without symptoms at blood lead levels above 10 micrograms/deciliter. At higher levels of exposure headache, fatigue, irritability and malaise may occur. At high levels, encephalopathy, seizures and focal neurologic findings with imminent risk of death, permanent mental retardation, and motor deficits may occur. Lead is transferred across the placenta. It can affect reproduction in males and females, and affects neurodevelopmental milestones in children with both prenatal and postnatal exposure.
Chronic lead exposure: abdominal pain, nausea, anorexia, vomiting, constipation, diarrhea, and a metallic taste in the mouth have been reported with chronic toxicity. Severe and paroxysmal colic characterized by a rigid and retracted abdomen may occur.
Highly toxic, may be fatal if inhaled, swallowed or absorbed through skin. Effects of contact or inhalation may be delayed.
Avoid any skin contact. See Inhalation.
Acute exposure - activated charcoal: administer charcoal as a slurry (240 ml water/30 g charcoal). Usual dose: 25 to 100 g in adults/adolescents. Consider gastric lavage in patients with recent ingestion of liquid or powdered products.
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.
Flush with water.
Immediately flush with running water for at least 20 minutes.
