During an IH survey of an automotive battery plant you evaluated worker exposures to airborne lead dust. One of the employee exposures evaluated was a battery plate stacker. This job consists of stacking lead oxide coated lead plates and placing them into the plastic battery case. The employee works an 8-hour shift and takes a half (1/2) hour lunch break and two 15-minute breaks during the day. Sampling showed the following exposures:
0.04 mg/m³ - for 6 hours while performing plate stacking
0.005 mg/m³ - for 1 hour during lunch and breaks
0.09 mg/m³ - for 1 hour during end of the cleaning
Remember: Both the OSHA PEL-TWA and the ACGIH TLV-TWA for lead is 0.05 mg/m³
a) What is the employee’s 8-hour TWA exposure to lead dust?
b) Is there an over exposure to the lead dust PEL and TLV?
