CRITICAL WARNINGS
1. HIGH TOXICITY: All lead oxides are highly toxic. Lead accumulates in the body causing neurological, hematological, and kidney damage. Prolonged exposure can be fatal.
2. CARCINOGENICITY: May cause cancer (IARC Group 2A). Avoid inhalation and ingestion.
3. REPRODUCTIVE TOXICITY: May damage fertility or the unborn child.
4. ENVIRONMENTAL HAZARD: Very toxic to aquatic life. Causes long-term adverse effects in the aquatic environment.
5. PPE: Full protective equipment (gloves, goggles, apron, respirator) is required when handling.
6. STORAGE: Store in closed containers, away from food and water sources. Separate from acids and reducing agents.
7. WASTE: Lead-containing waste must be disposed of according to hazardous waste regulations.
8. REGULATORY RESTRICTIONS: Subject to RoHS, ELV, and REACH restrictions.
9. ALTERNATIVES: Lead-free alternatives should be preferred whenever possible.
