Section 21. Fencing of machinery.-
(1) In every factory the following, namely-
(i) every moving part of a prime-mover and every flywheel connected to a prime-mover, whether the prime-mover or flywheel is in the engine-house or not;
(ii) the headrace and tailrace of every water-wheel and water-turbine;
(iii) any part of a stock bar which projects beyond the head stock of a lathe; and
(iv) unless they are in such position or of such construction as to be safe to every person employed in the factory as they would be if they were securely fenced, the following, namely:-
(a) every part of an electric generator, a motor or rotary convertor;
(b) every part of transmission machinery; and
(c) every dangerous part of any other machinery; shall be securely fenced by safeguards of a substantial construction which shall be constantly maintained and kept in position while the parts of machinery they are fencing, are in motion or in use:
Provided that for the purpose of determining whether any part of machinery in such position or is of such construction as to be safe as aforesaid, account shall not be taken of any occasion when-
(i) it is necessary to make an examination of any part of the machinery aforesaid while it is in motion or, as a result of such examination to carry out lubrication or other adjusting operation while the machinery is in motion, being an examination of operation which it is necessary to be carried out while that part of the machinery is in motion. or
(ii) in the case of any part of a transmission machinery used in such process as may be prescribed (being a process of a continuous nature, the carrying on of which shall be or is likely to be substantially interfered with by the stoppage of that part of the machinery), it is necessary to make an examination of such part of the machinery while it is in motion or, as a result of such examination, to carry out any mounting or shipping of belts or lubrication, or other adjusting operation while tlle machinery is in motion, and such examination or operation is made or carried out in accordance with the provisions of sub-section (1) of section 22.
(2) The State Government may by rules prescribe such further precautions as it may consider necessary in respect of any particular machinery or part thereof or exempt, subject to such condition as may be prescribed, for securing the sefety ofthe workers, any particular machinery or part thereof from the Provisions of this section.
Section 22. Work on or near machinery in motion.-
(1) Where in any factory it becomes necessary to examine any part of machinery referred to in section 21, while the machinery is in motion, or, as a result of such examination, to carry out-
(a) in a case referred to in clause (i) of the proviso to sub-section (1) of section 21, lubrication or other adjusting operation; or
(b) in a case referred to in clause (ii) of the proviso aforesaid, any mounting or shipping of belts or lubrication or other adjusting operation,
while the machinery is in motion, such – examination or operation shall be made or carried out only by a specially trained adult male worker wearing tight fitting clothing (which shall be supplied by the occupier) whose name has been recorded in the register prescribed in this behalf and who has been furnished with a certificate of his appointment, and while he is so engaged,-
(a) such worker shall not handle a belt at a moving pulley unless-
(i) the belt is not more than fifteen centimetres in width;
(ii) the pulley is normally for the purpose of drive and not merely a fly-wheel or balance wheel (in which case belt is not permissible);
(iii) the belt joint is either laced or flush with the belt;
(iv) the belt, including the joint and the pulley rim, are in good repair;
(v) there is reasonable clearance between the pulley and any fixed plant or structure;
(vi) secure foothold and, where necessary, secure handhold, are provided for the operator; and
(vii) any ladder in use for carrying out any examination or operation aforesaid is securely fixed or lashed or is firmly held by a second person ;
(b) without prejudice to any other provision of this Act relating to the fencing of machinery, every set screw, bolt and key on any revolving shaft, spindle, wheel or pinions and all spur, worm and other toothed or friction gearing in motion with which such worker would otherwise be liable to come into contact, shall be securely fenced to prevent such contact.
(2) No woman or young person shall be allowed to clean, lubricate or adjust any part of a prime-mover or of any transmission machinery while prime-mover or transmission machinery is in motion, or to clean, lubricate or adjust any part of any machine if the cleaning, lubrication or adjustment thereof would expose the woman or young person to risk of injury from any moving part either of that machine or of any adjacent machinery.
(3) The State Government may, by notification in the Official Gazette prohibit, in any specified factory or class or description of factories, the cleaning, lubricating or adjusting by any person of specified parts of machinery when those parts are in motion.
Section 23. Employment of young persons on dangerous machines.-
(1) No young person shall be required or allowed to work at any machine to which this section applies, unless he has been fully instructed as to the dangers arising in connection with the machine and the precautions to be observed, and-
(a) has received sufficient training in work at the machine, or (b) is under adequate supervision by a person who has a thorough knowledge and experience of the machine.
(2) Sub-section (1) shall apply to such machines as may be prescribed by the State Government, being machines which in its opinion are of such a dangerous character that young persons ought not to work at them unless the foregoing requirements are complied with.
Section 24. Striking gear and devices for cutting off power.-
(1) In every factory-
(a) suitable striking gear or other efficient mechanical appliance shall be provided and maintained and used to move driving belts to and from fast and loose pulleys which form part of the transmission machinery, and such gear or appliances shall be so constructed, placed and maintained so as to prevent the belt from creeping back on to the first pulley;
(b) driving belts when not in use shall not be allowed to rest or ride upon shafting in motion.
(2) In every factory suitable devices for cutting off power in emergencies from running machinery shall be provided and maintained in every workroom:
Provided that in respect of factories in operation before the commencement of this Act, the provisions of this sub-section shall apply only to workrooms in which electricity is used as power.
(3) When a device, which can inadvertently shift from “off” to “on” position, is provided in a factory- to cut off power, arrangements shall be provided for locking the device in safe position to prevent accidental starting of the transmission machinery or other machines to which the device it fitted.
Section 25. Self-acting machines.-
No traversing part of a self-acting machine in any factory and no material carried thereon shall, if the space over which it runs is a space over which any person is liable to pass, whether in the course of his employment or otherwise, be allowed to run on its outwards or inward traverse within a distance forty-five centimetres from any fixed structure which is not part of the machine:
Provided that the Chief Inspector may permit the continued use of a machine installed before the commencement of this Act which does not comply with the requirements of this section on such conditions for ensuring safety as he may think fit to impose.
