Fencing of machinery: In every factory, the following must be securely fenced by the safeguards of substantial construction which are kept in position while the parts of machinery required to be fenced are in motion or in use. You can also find training materials, safety posters and different safety signs from this Centre. Work on or near machinery in motion: If it becomes necessary to examine any part of machinery while the machinery is in motion, or as a result of such examination, to carry out any mounting or shipping of belts, lubrication or other adjusting operation while the machinery is in motion, such examination or operation may be made or carried out only by a specially trained adult male worker wearing tight fitting clothing.
