HC Deb 02 May 1940 vol 360 c928W
Mr. Mort

asked the Home Secretary whether his Department are contemplating making arrangements for the better ventilation of tin and steel works during the summer months, in view of the fact that the black-out regulations, which prevent the full flow of air, if not altered, will have a detrimental effect upon the workers' health?

Sir J. Anderson

The problem of ventilation in these works, to which special attention has been given, is complicated by the requirements of defence, particularly in regard to the prevention of glare. I fully recognise the importance of securing that adequate methods of ventilation shall be combined with methods for the prevention of glare, and the factory inspectors will continue to give special attention to the possibility of devising means of improvement.
