Waste water |
Normally, employees are not exposed to hazardous levels of airborne lead contaminants
while servicing and maintaining waste water treatment systems. However,
while handling lead-bearing wastes, sludge, and
filters employees may come in contact with lead-containing wastes.

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
while removing and transporting recovered
lead, filter
cake, or sludge.
- Employees
may contact lead-containing materials
during maintenance, repair
and cleanup operations.
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 lead contaminated water mists, when necessary, to prevent leaded materials from
drying.
