HC Deb 18 June 1931 vol 253 c1944
69. Mr. ERNEST WINTERTON

asked the Secretary for Mines when he will be able to report to the House on the results of the tests of automatic gas alarms designed to detect where gas is present in coal mines in sufficient quantities to constitute a danger to the men working therein?

Mr. GILLETT

The further pit trials, of which the House was informed in reply to a question on 27th April, have been carried out; and a detailed report on the results by the Safety in Mines Research Board is in preparation. My hon. Friend will review the position as soon as he receives this report.
