In this part, a lead process consists of one or more 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 0.1m2 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,
