178 What is a lead process?

A lead process consists of one or more of the following—

(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 the pasting or casting of lead;

(c) breaking up or dismantling of batteries containing lead, or sorting, packing and handling of plates or other parts containing lead removed or recovered from those batteries;

(d) spraying with molten lead metal or alloys containing more than 5% by weight of lead metal;

(e) melting or casting of lead alloys containing more than 5% by weight of lead metal in which the temperature of the molten material exceeds 450ºC;

(f) recovery of lead from its ores, oxides or other compounds by a thermal reduction process;

(g) dry machine grinding, discing, buffing or cutting by power tools of lead containing more than 5% by weight of lead metal;

(h) machine sanding or buffing of surfaces coated with paint containing more than 1% by dry weight of lead metal;

(i) a process in which electric arc, oxy‑acetylene, oxy gas, plasma arc or a flame is applied, for the purposes of welding, cutting or cleaning, to the surface of metal that is coated with lead or paint containing more than 1% by dry weight of lead metal;

(j) radiator repairs if exposure to lead dust or lead fumes may occur;

(k) fire assays, if lead is used;

(l) hand grinding and finishing of lead or alloy containing more than 50% by weight of lead metal;

(m) spray painting with lead paint containing more than 1% by dry weight of elemental lead;

(n) melting of lead metal or alloy containing more than 50% by weight of lead metal if the exposed surface area of the molten material is more than 0⋅1 square metres and the temperature of the molten material does not exceed 450ºC;

(o) use of a power tool, including abrasive blasting and high pressure water jets, to remove any surface coated with paint containing more than 1% by dry weight of lead metal and the handling of waste containing lead resulting from that removal;

(p) a process that exposes a person to lead dust or lead fumes arising from the manufacture or testing of detonators or other explosives that contain lead;

(q) a process that exposes a person to lead dust or lead fumes arising from the firing of weapons at an indoor firing range;

(r) foundry processes involving—
