Mr. WINTERTONasked the Secretary for Mines when he proposes to make it compulsory on all owners of collieries to use an approved and efficient gas detector and thus prevent the needless loss of miners' lives by possible explosions?
§ Mr. TURNERThe most generally useful and reliable gas detector for use in mines—and the only detector which can detect black-damp as well as firedamp—is the flame safety lamp; and the use of approved types of flame safety lamps for these purposes is already compulsory in all mines where there is likely to be danger from gas.
