LEAD DIOXIDE

Health hazards

Information OSHA Effects of Overexposure Skin Contact: Contact may cause skin irritation. Prolonged contact may allow for absorption through the skin. In extreme Information Effects of Overexposure Skin Contact: cases poisoning can occur with symptoms similar to those outlined under ingestion. Eye Contact: Contact may be irritating to the eyes. Absorption through the eyes may occur. Ingestion: Harmful or fatal if swallowed. Symptoms of lead poisoning inlcude abdominal pain and spasms, nausea, vomiting and headache. Acute poisoning can lead to muscle weakness, discoloration of the gums, metallic taste, loss of appetite, insomnia, dizziness, with shock, coma and death in extreme poisoning cases. Inhalation: Harmful or fatal if inhaled Lead can be absorbed through the respiratory system. Poisoning symptoms parallel those of ingestion. Irritation of the repiratory system may occur. Storage and Handling Precautions Store in a cool, dry well-ventilated area or cabinet dedicated to toxic storage. Isolate away from incompatible materials. Keep containers well closed. Areas in which exposure to lead compounds may occur should be identified by appropriate means and access restricted to authorized persons.

Potential chronic health

of Overexposure Lead is a cumulative poison and repeated exposure to even small amounts can raise the body's lead content to toxic levels. Symptoms of chronic exposure are similar to those of ingestion and restlessness, irritability, visual disturbances, hypertension and a gray pallor may also be noted. Exposure Limits: OSHA PEL TWA STEL Ceiling Lead dioxide (as Pb) 0.05 mg/m3 NE ACGIH TLV TWA STEL Ceiling Lead dioxide (as Pb) 0.15 mg/m3 NE Toxicity Data: Lead dioxide LD50 (intraperitoneal, guinea pig) 220 mg/kg

Medical Conditions Generally Aggravated by Exposure

Eye or skin conditions. Kidney, nerve, & circulatory disorders. Target Organs: None Identified Reproductive Effects: Lead is considered a reproductive system hazard. Carcinogenicity: For lead and lead compounds EPA/IRIS classification Group B2- Probable human carcinogen, sufficient animal evidence. Component NTP Listing IARC Listing OSHA Regulated Lead dioxide No listing Emergency First Aid Procedures Skin Contact: Immediately remove contaminated clothing. Flush skin with water for at least 15 minutes. Seek immediate medical attention. Eye Contact: Flush with water for at least 15 minutes. Seek immediate medical attention. Emergency First Aid Procedures Inhalation: Remove victim to fresh air. If not breathing, give artificial respiration. If breathing is difficult administer oxygen. Seek medical attention. Ingestion: Give victim large amounts of water and induce vomiting. Never give anything by mouth to an unconscious or convulsing person. Seek immediate medical attention. Additional First aid and Treatment Notes: No information available Reactivity Data Stability: Stable Hazardous Polymerization: Will Not Occur Incompatibles: Aluminum powder, magnesium, potassium, sodium, sulfides, phosphorus, hydrogen peroxide, nitrogen compounds, reducing materials Decomposition Products: Toxic fumes of lead Conditions to Avoid: Shock, friction, heat. Spill and Disposal Procedures Spill and Leak Procedures: Wear self-contained breathing apparatus and full protective clothing. Carefully sweep or scoop material into a clean, dry disposal container in a manner that minimizes dusting. Cover and save for proper disposal. Flush spill area with water. Contain runoff. Do not flush spill residues to sewer or storm drains. Vacuuming or wet sweeping may be used to avoid dust dispersal.

Disposal

Procedures Dispose in accordance with all Local, State and Federal regulations. Protective Equipment Ventilation: Use general or local exhaust ventilation to meet TLV and PEL requirements. Respiratory Protection: If airborne concentration exceeds PEL or TLV a dust/mist respirator with chemical goggles may be worn, in general, up to 10 times the TLV. or the maximum use concentration specified by the appropriate regulatory agency or respirator supplier, whichever is lower. A full face-piece, positive pressure, supplied air respirator should be on hand for emergency situations and instances where the airborne concentration is unknown. Skin and Eye Protective Equipment: Safety goggles, protective clothing and gloves. Maintain an eyewash station and safety shower nearby. Storage and Handling Precautions
