Hazards and Protection.
Keep in a cool, dry, dark location in a tightly sealed container or cylinder. Keep away from incompatible materials, ignition sources and untrained individuals. Secure and label area. Protect containers/cylinders from physical damage.
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 goggles, self-contained breathing apparatus and rubber gloves.
Follow the OSHA respirator regulations found in 29CFR 1910.134 or European Standard EN 149. Always use a NIOSH or European Standard EN 149 approved respirator when necessary.
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.
Reacts explosively with boric acid.
When heated to decomposition it emits very toxic fumes of lead and sulfur oxides.
Extinguish fire using agent suitable for type of surrounding fire. (Material itself does not burn or burns with difficulty.)
Contact with metals may evolve flammable hydrogen gas.
Toxic metal fumes
TLV (as Pb): ppm; 0.05 mg/m3 A3 (ACGIH 1996). MAK: ppm; 0.1 mg/m3; as Pb (1996).

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.
TOXIC; inhalation, ingestion, or skin contact with material may cause severe injury or death. Effects of contact or inhalation may be delayed.
Contact with molten substance may cause severe burns to skin and eyes. See Inhalation.
Corrosive. Contact can cause blurred vision, redness, pain and severe tissue burns. Absorption can occur through eye tissues but the more common hazards are local irritation or abrasion.
If swallowed, DO NOT INDUCE VOMITING. Give large quantities of water. Never give anything by mouth to an unconscious person. Get medical attention immediately.
Remove from source of exposure and keep quiet.
Wash with soap and water.
Wash with running water.
