(2.) In any case where the Inspector is of opinion that, by reason of the use of timber or other inflammable material in a mine, there is risk of fire, he may require the holder of the mine to provide such number and description of smoke-protectors as the Inspector thinks necessary, having regard to the nature and extent of the workings and of the risk. (3.) If inflammable gas has been found in the mine within the preceding twelve months, a station or stations shall be appointed at the entrance to the mine or to different parts of the mine, as the case may require, and no workman shall pass beyond any such station until the mine, or, as the case may be, the part beyond such station, has been cleared from gas, and been inspected and ascertained to be safe. (i.) Such inspection shall be made within two hours before the time fixed for the commencement of work. (5.) A printed copy of the foregoing general rules shall at all times be kept posted in the office, and on some building or board in a conspicuous place in connection with every mine, and shall be renewed as often as the same is torn or defaced. (6.) Subsection (46) of section 206 of the Mining Act (relating to offences) shall apply to the foregoing general rules. Special as to Dredges. 92. The following special rules shall be observed in the case of every dredge used for mining purposes : — (1.)

A life-buoy, a light line, and a boat-hook, near the stern of the dredge, (c.) A boat containing a light line and a boat-hook. (2.) In every case where the Warden or Inspector notifies the owner or manager of the dredge that the stream in which it is worked is deep or swift-flowing, then, in addition to the foregoing appliances, the dredge shall be kept provided with not less than two boats, each of which must be furnished with a life-buoy, a light line, and a boat-hook. Lifebelts shall also be provided, and each member of the crew of any boat shall wear a lifebelt when engaged in shifting the mooring-lines of the dredge. (3.) All safety appliances shall be kept in conspicuous places within easy reach, and when damaged or lost shall be immediately renewed. (4.) The well-hole of every dredge shall be fenced or covered over as far as is reasonably practicable, and where such fencing or covering is not practicable a movable gangway of not less than 2 ft. 6in wide, and fitted with a substantial handrail at each side, shall be provided and used by persons for crossing the well-hole. (5.) No person shall step on the buckets or chain when in motion. (6.) All exposed gearing, belting, or machinery shall be kept fenced to the satisfaction of the Inspector. (7.) On any dredge which is not entirely covered in, the sides of the uncovered portion of the hull shall be fitted with .stanchions not more than 8 ft. apart, and also with two substantial handrails or tightly-stretched wires or chains, the lower rail, wire, or chain not being more than 10 in. above the deck, and these may be made movable for the purpose of taking coal and material on board the dredge, but shall be kept in position at all other times. (8.) Every dredge working close to a bank shall be provided with a gangway not less than 2 ft. 6 in. wide, and of sufficient length to reach from the dredge to the bank. Such gangway shall be provided with a substantial handrail at each side, and be secured to the deck of the dredge.
