Western Australian Consolidated Regulations Western Australian Consolidated Regulations In this Subdivision,
unless the contrary intention appears —
atmospheric monitoring means determining the
concentration of lead in air;
biological monitoring means determining the amount
of lead in a person’s capillary or venous blood and the measurements
incidental to that determination;
blood lead level means the concentration of lead
in whole blood expressed in micromoles per litre (µmol/L) or micrograms
per decilitre (µg/dL);
confirmed blood lead level means the concentration
of lead in venous whole blood;
damp means sufficiently moist to prevent the
escape of dust;
health surveillance has the meaning that it has in
regulation 5.1 in relation to the hazardous substance of lead and
includes biological monitoring and medical examination, but not atmospheric
monitoring;
inorganic lead means lead metal, inorganic lead
compounds and lead salts of organic acids;
lead material means material containing metallic
lead or an inorganic lead compound in an amount such that the lead content of
the anhydrous material is in excess of 5% by weight;
lead process means any process
involving —
(a) the
use or handling of lead material; and
(b) any
work which exposes a person to lead dust in air or lead fumes arising from the
manufacture or handling of dry lead compounds; and
(c) any
work in connection with the manufacture, assembly, handling or repair of, or
parts of, electric accumulators which involves the manipulation of dry lead
compounds, pasting or casting of lead; and
(d) the
breaking up or dismantling of lead accumulators and the sorting, packing and
handling of plates or other parts containing the lead removed or recovered
from accumulators; and
(e)
spraying with molten lead or alloys containing greater than 5% by weight of
lead; and
(f)
spray painting with paint containing greater than 1% by dry weight of lead;
and
(g) the
storage, manipulation, movement, or other treatment of lead material whether
by means of any furnace, melting pot, retort, condensing chamber, flue, or
other container; and
(h)
melting or casting of lead alloys containing greater than 5% by weight of
lead; and
(i)
the cleaning or demolition of any furnace, melting pot,
retort, condensing chamber, flue, or container in which lead material has been
processed or contained; and
(j)
recovery of lead from its ores, oxides or other compounds by a thermal
reduction process; and
(k)
using any power tool to dry machine grind, buff or cut lead or alloy
containing greater than 5% by weight of lead; and
(l) hand
grinding and finishing of lead or alloy containing greater than 50% by weight
of lead; and
(m)
using a machine to sand or buff a surface coated with paint containing greater
than 1% by dry weight of lead; and
(n) the
application, for the purposes of welding, cutting or cleaning, of electric
arc, oxyacetylene, oxygas, plasma arc or a flame to the surface of any metal
which is coated with lead or paint containing greater than 1% by dry weight of
lead; and
(o)
radiator repairs where exposure to lead dust or fumes may occur; and
(p) fire
assay where lead is used; and
(q) any
other process determined by the Commissioner to be a lead process,
where the lead is inorganic lead;
lead‑risk job means a work activity or a
series of activities involving inorganic lead, in which the blood lead level
of a person might reasonably be expected to be, or is —
(a) in
the case of females of reproductive capacity, at least 20 micrograms per
decilitre (µg/dL); and
(b) in
any other case, at least 30 micrograms per decilitre (µg/dL);
removal level means a confirmed blood lead level
concentration at which, under regulation 5.63, a person is to be
transferred from a lead‑risk job to a job which is not a lead‑risk
job.
