Lead dust can become airborne due to improper air flow or exhaust ventilation, which results in "puffing" of lead oxide at the mill inlet. Exposure may occur from handling lead pigs while loading the mill pots or the ball mill. Lead oxide dust may spill or leak from trunnion seals, bearing seals, conveying systems, and transfer points.

The general method in literature for determining acid absorption is described by adding a known amount of manufactured lead oxide (usually 50 g) to a solution of sulphuric acid (100 mL SG) at 25 °C [ 1, 2, 4 ]. Heubach [ 3] specified the temperature of the analysis to be 32 °C.

Lead oxide used in the production of battery paste is currently produced by two methods: in a Barton reactor and in a ball mill. The Barton reactor consists of a lead melting furnace and a reaction vessel equipped with a rapidly rotating stirrer. Additionally the vessel is located in a heated chamber.
