Dust precautions.

95.—(1) Where, in connection with the carrying on of a process at a quarry, elsewhere than in a building, there is given off dust of such character and in such quantity as to be likely to be injurious to the persons employed, it shall be the duty of the manager to ensure that such steps are taken as are necessary to protect those persons against inhalation of the dust.
|
|
| |
(2) Where, in connection with the carrying on of any operations or process in a building at a quarry, there is given off dust of such character and in such quantity as to be likely to be injurious to the persons employed, it shall be the duty of the manager to ensure—
|
|
| |
(a) that the entry of the dust into the air or its accumulation in any place in circumstances in which its accumulation in that place might be harmful is minimised by means of steps in that behalf taken as near as possible to the point of origin of the dust,
|
|
| |
(b) that any of the dust which enters the air is trapped or so dispersed as to render it harmless, and
|
|
| |
(c) that any of the dust which is not prevented from accumulating in a place in circumstances in which its accumulation in that place might be harmful is either systematically cleaned up and removed to a place where it cannot be harmful or treated in manner approved by the Minister for the purpose of rendering it harmless.
|

(3) Regulations may impose upon managers of quarries requirements with respect to the use of prescribed apparatus and the taking of prescribed steps for the purpose of attaining any of the objects mentioned in this section; and the regulations may provide either that compliance therewith by the manager of a quarry is to be taken, either without qualification or to a prescribed extent, as compliance with all or any of the requirements of this section or that compliance with the regulations by the manager of a quarry is not necessarily to be taken as compliance with any of the said requirements.
