392 Meaning of lead process—pt 7.2
In this part, a lead process consists of any of the following carried out at a workplace:
work that exposes a person to lead dust or lead fumes arising from the manufacture or handling of dry lead compounds;
work in connection with the manufacture, assembly, handling or repair of, or parts of, batteries containing lead that involves the manipulation of dry lead compounds, or pasting or casting lead;
breaking up or dismantling batteries containing lead, or sorting, packing and handling plates or other parts containing lead that are removed or recovered from the batteries;
spraying molten lead metal or alloys containing more than 5% by weight of lead metal;
melting or casting lead alloys containing more than 5% by weight of lead metal in which the temperature of the molten material exceeds 450°C;
recovering lead from its ores, oxides or other compounds by thermal reduction process;
dry machine grinding, discing, buffing or cutting by power tools alloys containing more than 5% by weight of lead metal;
machine sanding or buffing surfaces coated with paint containing more than 1% by dry weight of lead;
a process by which electric arc, oxyacetylene, oxy gas, plasma arc or a flame is applied for welding, cutting or cleaning, to the surface of metal coated with lead or paint containing more than 1% by dry weight of lead metal;
radiator repairs that may cause exposure to lead dust or lead fumes;
fire assays if lead, lead compounds or lead alloys are used;
hand grinding and finishing lead or alloys containing more than 50% by dry weight of lead;
spray painting with lead paint containing more than 1% by dry weight of lead;
melting lead metal or alloys containing more than 50% by weight of lead metal if the exposed surface area of the molten material exceeds 0.1 square metre and the temperature of the molten material does not exceed 450°C;
using a power tool, including abrasive blasting and high pressure water jets, to remove a surface coated with paint containing more than 1% by dry weight of lead and handling waste containing lead resulting from the removal;
a process that exposes a person to lead dust or lead fumes arising from manufacturing or testing detonators or other explosives that contain lead;
a process that exposes a person to lead dust or lead fumes arising from firing weapons at an indoor firing range;
foundry processes involving—
melting or casting lead alloys containing more than 1% by weight of lead metal in which the temperature of the molten material exceeds 450°C; or
dry machine grinding, discing, buffing or cutting by power tools lead alloys containing more than 1% by weight of lead metal;
a process decided by the regulator to be a lead process under section 393.
