Chapter 7 Part 7.6 Clause 199
199   Definitions
In this Part:
blood lead level means the concentration in whole blood expressed in micromoles per litre (µmol/L) or micrograms per decilitre (µg/dL).
lead means lead metal, inorganic lead compounds and lead salts of organic acids.
lead process means any one of the following processes:
(a)  any work that exposes a person to lead dust in air or lead fumes arising from the manufacture or handling of a dry lead compound, except galena (lead sulphide) when its character or composition remains unchanged,
(b)  any work connected with the manufacture, assembly, handling or repair of, or parts of, electric accumulators (batteries) that involves the manipulation of dry lead compounds, pasting or casting lead,
(c)  breaking up or dismantling of lead accumulators and the sorting, packing and handling of plates or other parts containing lead removed or recovered from those accumulators,
(d)  spraying with molten lead, alloys or lead paint containing more than 5 per cent by weight of lead,
(e)  melting or casting of lead alloys containing more than 5 per cent by weight of lead in which the temperature of the molten material is more than 450 degrees Celsius,
(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 or alloy containing more than 5 per cent by weight of lead,
(h)  machine sanding or buffing of surfaces coated with paint containing more than one per cent by dry weight of lead,
(i)  any process by 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 any metal that is coated with lead or paint containing more than one per cent by dry weight of lead,
(j)  radiator repairs if exposure to lead dust or fumes may occur,
(k)  fire assay if lead is used,
(l)  melting of lead or alloy containing more than 50 per cent lead by weight if the exposed surface area of the molten material is more than 0.1 square metres and the temperature of the molten material exceeds 450 degrees Celsius.
lead risk work means a lead process or a work activity or sequence of activities at a specific area within a place of work in which the blood lead level of an employee might reasonably be expected to rise or does rise above 1.45 µmol/L (30 µg/dL).
