Eye Contact: Rinse immediately with gentle, clean water for several minutes lifting eyelids, remove contact lenses if present and easy to do, get medical attention for persistent irritation
Ingestion: Do not induce vomiting, rinse mouth with water, give water to drink if the person is fully conscious, seek immediate medical advice
Special Recommendations: Monitor victim for lead poisoning symptoms, provide information on possible exposure route to healthcare professionals
Suitable Extinguishing Media: Use extinguishing agents suitable for the surrounding fire such as dry powder, CO2, foam, or water spray
Unsuitable Media: Avoid full water jet
Specific Hazards: Product is not flammable, but toxic fumes including lead oxide and lead fumes can form in a fire
Protective Equipment: Firefighters require self-contained breathing apparatus and full protective clothing to prevent exposure to fumes
Special Procedures: Evacuate area if large amounts involved, keep unnecessary people away, cool affected containers with water spray
Personal Precautions: Wear protective equipment including gloves, goggles, and an appropriate respirator, wash hands thoroughly after handling, restrict access to spill area
Environmental Precautions: Prevent entry into drains, water courses, or soil; notify authorities if large spills could threaten groundwater or the environment
Containment: Secure spill area, suppress dust by moistening with water if safe, use barriers to prevent spreading
Cleanup Methods: Sweep up or vacuum spilled lead monoxide while minimizing dust, gather in properly labeled containers for safe disposal, do not use compressed air
Decontamination: Wash area thoroughly with water after cleanup, dispose of wash water as contaminated waste
Handling: Use local or general exhaust ventilation, avoid dust generation and buildup, wear recommended protective gear, keep away from food, drinks and smoking materials
Storage: Store in closed, labeled containers placed in dry, cool, and well-ventilated areas away from acids and incompatible materials
Incompatibilities: Strong acids, reducing agents, ammonium salts, organics, easily oxidizable materials
Special Storage Conditions: Protect from physical damage, frequent inspections for leaks or breakdowns, store dust-contaminated protective clothes separately
