392Meaning of lead process

392  Meaning of lead process   In this Part, a lead process consists of any of the following carried out at a workplace:  (a) work that exposes a person to lead dust or lead fumes arising from the manufacture or handling of dry lead compounds;  (b) 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;  (c) 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;  (d) spraying molten lead metal or alloys containing more than 5% by weight of lead metal;  (e) 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;  (f) recovering lead from its ores, oxides or other compounds by thermal reduction process;  (g) dry machine grinding, discing, buffing or cutting by power tools alloys containing more than 5% by weight of lead metal;  (h) machine sanding or buffing surfaces coated with paint containing more than 1% by dry weight of lead;  (i) 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;  (j) radiator repairs that may cause exposure to lead dust or lead fumes;  (k) fire assays if lead, lead compounds or lead alloys are used;  (l) hand grinding and finishing lead or alloys containing more than 50% by dry weight of lead;  (m) spray painting with lead paint containing more than 1% by dry weight of lead;  (n) 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;  (o) 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;  (p) a process that exposes a person to lead dust or lead fumes arising from manufacturing or testing detonators or other explosives that contain lead;  (q) a process that exposes a person to lead dust or lead fumes arising from firing weapons at an indoor firing range;  (r) foundry processes involving:  (i) 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  (ii) dry machine grinding, discing, buffing or cutting by power tools lead alloys containing more than 1% by weight of lead metal;  (s) a process decided by the regulator to be a lead process under regulation 393.
