asked the Home Secretary whether, in the interest of the health of the employees and to secure fuel economy, he will prohibit the use of blackout in factories during the hours of daylight, except where special circumstances make this necessary and then only by Government permit?
The Government policy is described in my statement of 23rd September, 1943, to which I would refer my hon. Friend. Removable blackout has always been recommended, where practicable, as preferable to permanent blackout. The immediate substitution of removable for permanent blackout would, however, be impracticable owing to the quantities of material and labour required, and the prohibition suggested would therefore seriously affect production. My right hon. Friend the Minister of Production is doing what is possible with the resources at his disposal to improve the position.
