(1) Section 418F does not apply to work that involves processing engineered stone benchtops, panels or slabs if the work—
(a) is carried out—
(i) for genuine research and analysis; or
(ii) to sample and identify engineered stone; or
(iii) to remove, repair or make minor modifications to engineered stone installed—
(A) before 1 July 2024; or
(B) in circumstances mentioned in section 418G; or
(iv) to dispose of engineered stone, whether it is installed or not; and
(b) is controlled.
(2) In this section:
"controlled"—work involving processing engineered stone benchtops, panels or slabs is controlled if any risk associated with the work is—
(a) eliminated so far as is reasonably practicable; or
(b) if it is not reasonably practicable to eliminate the risk—minimised so far as is reasonably practicable by—
(i) using a water delivery system supplying a continuous feed of water over the processing area to suppress airborne crystalline silica produced by the processing; and
(ii) using at least 1 other crystalline silica control measure; and
(iii) ensuring each worker at the workplace who may be exposed to airborne crystalline silica produced by the processing—
(A) is provided with respiratory protective equipment; and
(B) wears the respiratory protective equipment while the work is carried out.
