PART II Safety (General Provisions).

15 Provisions as to unfenced machinery.
In determining, for the purposes of the foregoing provisions of this Part of this Act, whether any part of machinery is in such a position or of such construction as to be as safe to every person employed or working on the premises as it would be if securely fenced—
(a) no account shall be taken of any person carrying out, while the part of machinery is in motion, an examination thereof or any lubrication or adjustment shown by such examination to be immediately necessary, being an examination, lubrication or adjustment which it is necessary to carry out while the part of machinery is in motion; and
(b) in the case of any part of transmission machinery used in any such process as may be specified in regulations made by the Secretary of State, being a process where owing to the continuous nature thereof the stopping of that part would seriously interfere with the carrying on of the process, no account shall be taken of any person carrying out, by such methods and in such circumstances as may be specified in the regulations, any lubrication or any mounting or shipping of belts :
Provided that this section shall only apply where the examination, lubrication or other operation is carried out by such persons, being male persons who have attained the age of eighteen, as may be specified in regulations made by the Secretary of State, and all such other conditions as may be so specified are complied with.
