Rule 147. Cotton Ginning

(1) The line shaft or second motion shall be completely enclosed by a continuous wall or unclimbable fencing with only so many openings as are necessary for access to the shaft for removing cotton seed, cleaning and oiling and such openings shall be provided with gates or doors which shall be kept closed and locked.

(2) The feed-mouth of the opener shall be fitted with a traverser or a grid guard so as to render it impossible for the operatives to be within reach of the beaters when feeding on to the lattice; and discharge ends shall be guarded so as to prevent the operatives from inadvertently coming within reach of the beaters.

(3) The spur gearing at the side of the opener shall be completely covered by a strong metal guard.

(4) The crank shaft pulleys and roller pulleys of all gins shall be securely guarded by strong box guards hinged top covers.

(5) The spur wheels, oscillating levers and rollers of gins shall be provided with guards.

(6) All ginning machines and openers shall be provided with fast and loose pulleys and efficient belt shifters. 148 Wood working machinery:

(1) Definitions:-For the purposes of this schedule,-a) "Wood-working machine" means a circular saw, band saw planning machine, chain mortising machine or vertical spindle moulding machine operating on wood or cork. b) "Circular saw'' means a circular saw working in a bench (including a rack bench) but does not include a pendulum or similar saw which is moved towards the wood for the purpose of cutting operation. c) "Band saw" means a band saw, the cutting portion of which runs in vertical direction but does not include a log saw or band resawing machine. d) "Planning machine" means a machine for overhand planning or for thicknessing or for both operations.

(2) Stopping and starting device:- An efficient stopping and starting device shall be provided on every wood working machine.The control of this device shall be in such a position as to be readily and conveniently operated by the person in charge of the machine.

(3) Space around machines:- The space surrounding of every wood working machine in motion shall be kept free from obstruction.

(4) Floors:- The floor surrounding every wood working machine shall be maintained in good and, level condition, and shall not be allowed to become slippery, and as far as practicable, shall be kept free from chips or other loose material.

(5) Training and supervision:-a) No person shall be employed at a wood-working machine unless he has been sufficiently trained to work that class of a person who has a thorough knowledge of the working of the machine. b) A person who is being trained to work at a wood working machine shall be fully and carefully instructed as to the dangers of the machine and the precautions to be observed to secure safe working of the machine.

(6) Circular saws:-Every circular saw shall be fenced as follows:-a) Behind and in direct line with the saw there shall be a riving knife, which shall have a smooth surface shall be strong, rigid and easily adjustable, and shall also conform to the following conditions:-(i) The edge of the knife nearer the saw shall form an area of a circle having a radius not exceeding of the largest saw used on the bench.

(ii) The knife shall be maintained as close as practicable to the saw, having regard to the nature of the work being done at the time, and at the level of the bench table the distance between the front edge of the knife and teeth of the saw shall not exceed half an inch.

(iii) For a saw of a diameter of less than 60 cms. the knife shall extend upwards from the bench table to within 25 mm of top of the saw, and for a saw of a diameter of 60 cms or over shall extend upwards from the bench table to a height of at least nine inches.

(iv) The top of the saw shall be covered by a strong and easily adjustable guard, with a flange at the side of the saw farthest from the fence. The guard shall be kept so adjusted that the side flange shall extend below the roots of the teeth of the saw. The guard shall extend from the top of the riving knife to a point as low as practicable at the cutting edge of the saw.

(v) The part of the saw below the bench table shall be protected by two plates of metal or other suitable material one on each side of the saw; such plates shall not be more than 15cm apart, and shall extend from the axis or the saw outwards to a distance of not less than 5 cm beyond the teeth of the saw. Metal plates, if not be added, shall be of a thickness of at least 12.5 mm or, if be added be of a thickness of at least 1.25 mm.

(7) Push sticks:- A push stick or other suitable appliance shall be provided for use at every circular saw and at every vertical spindle moulding machine to enable the work to be done without unnecessary risk.

(8) Bandsaws :-Every bandsaw shall be guarded as follows :-a) Both sides of the bottom pulley shall be completely encased by sheet or expanded metal or other suitable material. b) the front of the top pulley shall be covered with sheet or expanded metal or other suitable material. c) All portions of the blade shall be enclosed or otherwise securely guarded except the portion of the blade between the bench table and the top guide.

(9) Planning machines:-a) A planning machine (other than a planning machine which is mechanically fed) shall not be used for overhand planning unless it is fitted with a cylindrical cutter block. b) Every planning machine used for overhand planning shall be provided with a 'bridge', guard capable of covering the full length and breadth of the cutting slot in the bench, and so constructed as to be easily adjusted both in a vertical and horizontal direction. c) The feed roller of every planning machine used for thicknessing except the combined machine for overhand planning and thicknessing, shall be provided with an efficient guard.

(10) Vertical spindle moulding machines:-- a) The cutter of very vertical spindle moulding machine shall be guarded by the most efficient guard having regard to the nature of the work being performed. b) The wood being moulded at a vertical spindle moulding machine shall, if practicable, be held in a jig or holder of such construction as to reduce, as far as possible, the risk of accident to the worker.

(11) Chain mortising machines:-The chain of every chain mortising machine shall be provided with a guard which shall enclose the cutters as far as practicable.

(12) Adjustment and maintenance of guards:- The guards and other appliance, required under this schedule shall be-a) Maintained in an efficient state b) Constantly kept in position while the machinery is in motion; and c) So adjusted as to enable the work to be done without unnecessary risk. Exemptions:-Paragraphs f, h, i and j shall not apply to any wood-working machine in respect of which it can be proved that other safeguards are provided, maintained and used which render the machine as safe as it would be if guarded in the manner prescribed in this schedule
