Ingestion: Rinse mouth. Do not induce vomiting. Seek medical advice without delay. If unconscious, do not give anything by mouth.
Most Important Symptoms: Abdominal pain, headache, nausea, vomiting, confusion, anemia, neurological symptoms.
Indication of Immediate Medical Attention: If exposed or concerned, medical evaluation is necessary for chelation therapy and symptomatic management.
Extinguishing Media: Use dry chemical, foam, or carbon dioxide. Do not use water jets directly.
Hazardous Combustion Products: Emits toxic fumes of chlorine and lead oxides in fire situations.
Specific Hazards: Material is toxic; runoff from firefighting may pollute waterways. Protect against inhaling gases.
Special Protective Equipment: Wear full protective gear and self-contained breathing apparatus; avoid skin and eye contact.
Advice for Firefighters: Isolate the area and evacuate all non-emergency personnel. Prevent entry of water stream into sewers and waterways.
Personal Precautions: Evacuate unnecessary personnel. Isolate area and ventilate well. Wear suitable respiratory protection, gloves, and chemical-resistant clothing for cleanup.
Environmental Precautions: Prevent further leakage or spillage. Block entry to sewers, surface water, or soil.
Containment and Cleaning: Scoop or vacuum up spilled material. Avoid dust generation. Place in labeled chemical waste containers for disposal.
Decontamination: Wash contaminated surfaces and clothing with soap and water. Ensure all equipment used is thoroughly cleaned.
Notification: Report significant releases to environmental protection authorities as required by regulations.
Handling: Handle in a well-ventilated place. Avoid direct contact with skin, eyes, and clothing. Use closed systems if possible to minimize dust.
Hygiene Measures: Do not eat, drink, or smoke in areas where chemical is handled. Wash hands before breaks and after work.
Storage Requirements: Store in a tightly sealed container, kept in a cool, dry, ventilated place away from acids, bases, and foodstuffs.
Incompatible Materials: Avoid storage with ammonium salts, strong oxidizers, strong acids, and alkalis.
Segregation: Keep separate from explosive or easily oxidizable materials to reduce risk of hazardous chemical reactions.
Exposure Limits: OSHA PEL: 0.05 mg/m3 (as Pb); ACGIH TLV: 0.05 mg/m3 (as Pb)
Engineering Controls: Use local exhaust ventilation or fume hoods to control airborne dust
Personal Protective Equipment: Protective gloves, chemical-resistant clothing, safety goggles, face shield
Respiratory Protection: Approved respirators required in absence of adequate ventilation or high exposure risk
Environmental Controls: Equipment should be used only in well-ventilated areas or with fume extraction. Prevent accidental emission into the environment.
