HC Deb 25 January 1940 vol 356 c801W
Mr. White

asked the Home Secretary whether he is aware that in many in-stances factory windows have been painted with black paint, and how the ventilation regulations of the Factory Act are complied with after black-out time?

Sir J. Anderson

The problem of maintaining ventilation at times when windows have to be obscured is one to which the Factory Department has given special attention. The inspectors were given instructions based on the experience acquired by the Department and on information obtained from technical bodies. As a result, the inspectors have been able to make recommendations which would enable factory occupiers to overcome the difficulty in a variety of ways, and satisfactory progress has been made in remedying the conditions which obtained in certain factories in the early days after the outbreak of war.
