|
|
| |
(a) any dust that is inflammable, and

|
|
| |
(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 dangerous or 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 might be dangerous or harmful is either systematically cleaned up and removed to a place where it cannot be dangerous or harmful or treated in manner approved by the Minister for the purpose of rendering it harmless.
