7 Prevention of discharge of noxious or offensive gas in scheduled works

(1) The owner of any work specified in the First Schedule to this Act (herein-after referred to as a scheduled work) shall use the best practicable means for preventing the escape of noxious or offensive gases by the exit flue of any apparatus used in any process carried on in the work, and for preventing the discharge, whether directly or indirectly, of such gases into the atmosphere, and for rendering such gases where discharged harmless and inoffensive, subject to the qualification that, on the basis of the amount of acid gas per cubic foot, no objection shall be taken under this section by an inspector—

(a) To any muriatic acid gas in the air, smoke, or gases discharged into the atmosphere by a chimney or other final outlet, where the amount of such acid gas in each cubic foot of air, smoke, or gases so discharged does not exceed the amount limited by the last preceding section:

(b) To any acid gases in the air, smoke, or gases discharged into- the atmosphere by a chimney or other final outlet receiving the residual gases from any process for the concentration or distillation of sulphuric acid, where the total acidity of such acid gases (including those from the combustion of coal) in each cubic foot of air, smoke, or gases so discharged does not exceed what is equivalent to one grain and a half of sulphuric anhydride.

(2) If the owner of any such work fails, in the opinion of the court having cognisance of the matter, to use such means, he shall be liable to a fine not exceeding in the case of the first offence twenty pounds, and in the case of every subsequent offence fifty pounds, with a further sum not exceeding five pounds for every day during which any such subsequent offence has continued.
