Potential Sources of Exposure:
- Liquid lead waste may splash on equipment and become airborne if it dries and becomes disturbed.
- Employees may contact leaded waste products during removal and transport of recovered lead.
Possible Engineering and Work Practice Controls:
- Ensure that appropriate PPE is provided and used when handling leaded materials.
- Transfer recovered lead in covered or closed containers.
- Clean up spills and water mists, when necessary, to prevent leaded materials from drying.
