(i)no machinery or equipment which is likely to emit dust in excess of permissible limit shall be operated unless it is equipped with a suitable dust-prevention and suppression device which shall be properly interlocked with the operating lever or switch and unless such device is operating efficiently;
(ii)the design, arrangement, material and condition of picks on every mechanical coal cutter Shall be such as to reduce the formation of dust to the minimum and no mechanical coal cutter Shall be operated unless suitable water sprays or jets of water are directed on the cutting edges thereof so as to damp the cuttings as they are formed;
(iii)every working face and the floor, roof and sides of every roadway or airway within 50 metres thereof shall be, unless naturally wet throughout, regularly washed down to prevent accumulation of dust and shall be kept thoroughly wet during the work shifts;
