§ Mr. Richards
asked the Secretary for Mines when was the sealed part of the Gresford mine last tested for gas, and what was the result?
§ Captain Crookshank:
Air samples from behind the stoppings at Gresford Colliery were last taken on 17th May. The analyses of these samples have just reached me and the results indicate that the air inside the stoppings is still such that it is unsafe to remove them.
