No. 10.] THE ORDINANCES OF HONGKONG [A.D. 1900.
(3.) The interior surfaces of all walls, which must be substantially built of brick or stone, as well as the surfaces of the brick or stone supports of pans, etc., shall be rendered smooth and impervious, to the height of at least seven feet from the floor level, with asphalt, Portland cement, or such other material as the Board may approve of.
(4.) All such premises shall be provided, to the satisfaction of the Board, with proper and adequate urinal and privy accommodation for the use of the workmen employed thereon.
3. Every bone-boiler, tallow-melter, fat-melter, or fat-extractor shall cause all materials which have been received upon the premises where his trade is carried on, and which are not immediately required for boiling, melting, or extracting, to be stored in such manner and in such a situation as to prevent the emission of noxious or injurious effluvia therefrom.
4. Every bone-boiler, tallow-melter, fat-melter, or fat-extractor shall cause such portions of the internal surface of every wall upon the premises where his trade is carried on as have not been rendered impervious with suitable material to be thoroughly cleansed, and, after being so cleansed, to be lime-washed with hot lime-wash, during the months of March and October in each year.
5. Every bone-boiler, tallow-melter, fat-melter, or fat-extractor shall, at the close of every working day, cause all fat, tallow, grease, refuse, which has been spilled or splashed, or has fallen or been deposited upon any floor, pavement, or wall upon the premises where his trade is carried on, to be collected therefrom by scraping or some other effectual cleansing, and, unless it is intended to be subjected to further treatment on the premises, forthwith removed from the premises. All apparatus shall be kept in a cleanly and wholesome condition.
6. Every bone-boiler, tallow-melter, fat-melter, or fat-extractor shall cause every part of the internal surface of the walls and every floor or pavement upon the premises where his trade is carried on to be kept at all times in good order and repair, so as to prevent the absorption therein of any filth, or refuse, or any noxious or injurious matter which may be splashed, may fall or be deposited thereon.
7.--(1.) Every bone-boiler, tallow-melter, fat-melter, or fat extractor shall adopt the best practicable means of rendering innocuous all vapours arising during the process of such boiling, melting, or extraction, upon the premises where his trade is carried on.
(2.) He shall, in every case, either cause the vapour to be discharged into the external air in such a manner and at such a height as to admit of the diffusion of the vapour without noxious or injurious effects, or he shall cause the vapour to pass directly from the pan or press through a suitable condensing apparatus and then through a fire in such a manner as effectually to consume the vapour or to deprive the same of all noxious or injurious properties.
