Handling and
transporting of materials is an essential part of the battery manufacturing process. Materials
are primarily transported through the use of mobile equipment (forklifts). Proper operator training,
prudent work practices, and good housekeeping are key in minimizing lead emissions during mobile equipment operation. Conversely, careless equipment operation coupled with inadequate housekeeping can lead to serious lead exposure throughout the plant.

Potential Sources of
Exposure
- Lead dust from feed materials can become airborne during handling and transport
(Figure 1).
- Lead dust that has
settled on surfaces and equipment may become airborne
due to vehicle traffic and cross-drafts.
Possible Engineering and Work Practice
Controls
- Reduce vehicle speeds to minimize stirring up
settled dust.
- Clean
the inside and outside of mobile equipment
frequently.
- Periodically
clean floor surfaces to
reduce accumulation of
lead dust.
- Pave all roadways to facilitate
housekeeping.
- If it is determined that lead dust is coming from mobile equipment or is from adjacent areas, evaluate material handling patterns and practices and area isolation.
- Provide
dedicated fork lifts for
clean and dirty areas to
avoid cross contamination.
- Raise and lower loads gently to prevent
jarring.
- Vacuum any skid, pallet, tub, or other conveyance
that holds or has held plates before
moving.
Other
Hazards
- Vehicle accidents may occur during the
material transport, which
may release contaminated material throughout the plant.
Possible
Solutions
- Ensure that each vehicle is equipped with hazard lights and audible
horns.
- Ensure that loading and receiving docks are clearly marked and lighted.
- Write schedules for all drivers and operators, to minimize
"surprises."
