On the section. Sub-section (3) reads as follows:—
" If the Minister is satisfied that, owing to the special conditions under which the work is carried on in any workroom in which explosive materials are manufactured or handled, the application of sub-section (2) of this section to the workroom would be inappropriate or unnecessary, he may by certificate except the workroom from that sub-section subject to any conditions specified in the certificate."
Sub-section (2) reads as follows:—
" Without prejudice to the generality of subsection (1) of this section, a factory shall be deemed to be so over-crowded as to cause risk of injury to the health of persons employed therein if the number of persons employed at the time in any workroom is such that the amount of cubic space allowed for every person employed in a room is less than 400 cubic feet."
There are cases where that requirement in relation to 400 cubic feet per person would be unnecessary, but if it is unnecessary then what the Minister can do there would hardly appear to be relevant. In fact, I do not know why that possibility is only in connection with workrooms where explosive materials are manufactured or handled.
