Hydrosetting oven
|
Hydrosetting methods vary
between battery plants, ranging from placing the pasted plate racks in the
workroom to placing the racks within a temperature- and humidity-controlled
room or chamber. The major source of lead exposure in the hydrosetting process comes from
lead oxide when the grids are handled incorrectly.

Potential Sources of
Exposure
- Lead may become airborne from handling or moving dry plates.
- Lead particulate may become airborne from positioning pallets of pasted plates near drafts or thermals.
- Handling burlap, used to cover grids, that has been contaminated with lead oxide improperly.
Possible Work Practice Controls
- Do not cover with burlap; instead use plastic or some other material that will not become heavily
contaminated.
- Position pallets away from cross drafts or thermals.
- Vacuum pallets, racks, and edges of plates and panels to prevent dried
lead-bearing dust from being re-entrained.
- Provide adequate PPE, a change of clothes, and shower rooms (see OSHA Lead Requirements for PPE, Housekeeping, and Hygiene Facilities).
