I move amendment No. 16:—
In sub-section (4), line 38, to delete " so far as practicable ".
I can see at the moment no good reason why, if windows and skylights are provided, there should not be an obligation placed on the employer to keep them clean and I cannot conceive any great practical difficulties to make that possible. If there are practical difficulties they can be overcome. To allow exemption from that sub-section on the ground of practicability, is to leave a very wide loophole. From the point of view of safety, lighting is very important. We try to get natural daylight if we can and the least we should ensure is that windows and skylights are kept clean. I am at a loss to understand why this limiting clause has been put in.
