適用范圍： This standard enunciates the principles of mechanical guarding of machinery and outlines certain broad principles that are applicable to all guarding situations. A few illustrations showing the techniques of mechanical guarding as applied to specific machines are given in Appendix D. Even where specific devices or methods are mentioned in this standard, other devices or methods which will ensure equally good safety may be used. Machinery which cannot be guarded in accordance with legal requirements under Factories Act, 1948, while remaining commercially practicable or mechanically useful, should not be used. It must be borne in mind that absence of injury from operating a machine is no proof that the machine is safe for operation. The mere technical fulfilment of these requirements does not ensure proper safeguarding if examination shows lack of practicability and/or durability.
