Surprisingly the 1954 Act still permitted the continued use of naked lights in mines where they had been in general use prior to it coming into force -1st January 1957.
sparty-lea was quite right about the Alston drifts - carbide lamps, and safety fuse for shotfiring up until about 20 years ago. HMI gradually stopped these practices to bring them in line with the safety lamp mines. Although electric cap lamps and dets were universally adopted the smokers seemed oblivious to the contraband regs. When HMI visited (always courteously giving notice) all fags and lighters were clearly to be seen on a shelf in the surface hauler house. As soon as he left the next set of empties took 'em inbye. ::) One lad even poked holes in his dust mask so he could smoke with it on!
Understandable as the desire was to rid any coal mine, gassy or not, of an ignition source (they used to reckon on 12% of u/g fires being caused by naked lights) some of the "requests" by HMI weren't exactly welcomed. I remember one man (chain smoker) in a hard rock mine asking "Is that inspector for real - he's just told me I can't smoke down here in case I start a fire. It's nowt but solid rock and p***ing wet through. He reckons I could set light to somebody's clothes :curse: I'd have to use a blowtorch to dry them out first. :curse: "
