Regulation 28 Separation of Processes
When a scheduled process is carried on in a room in which thimble picking, threading-up, or any other process which is not scheduled is also carried on, then:—
if the scheduled process is carried on only in a part of the room clearly separated from the rest of that room by a barrier, guard rail or (where neither of these is practicable) a clear line of demarcation, then (unless there is in force a certificate issued under sub-paragraph (b) below) every person employed in that part of the room shall be deemed to be a person employed in a scheduled process;
if the scheduled process is not thus clearly separated or if the Inspector for the District has issued and there remains in force a certificate that the arrangements for separation are not in his opinion satisfactory, then every person employed anywhere in that room shall be deemed to be a person employed in a scheduled process.
Before issuing a certificate under sub-paragraph (b) of paragraph (1) the Inspector for the District shall take into account the size of the room and the spacing between processes.
A legible copy of any such certificate for the time being in force shall be kept posted up in the room to which it relates in a position where it may conveniently be read by the persons employed.
Every slip-house shall for the purpose of excluding dust be effectually separated from:—
any place in which clay is dried,
any place in which clay is taken from a drier, and
any place in which the dry grinding or sieving of materials for pottery bodies is carried on.
