But firedamp explicitly refers to a gas mixture rich in the flammable gas methane, which - as the recent disaster in West Virginia's Upper Branch Mine reminds us - burns like a devil's torch. Twenty-five miners were killed outright in the…

So that one can make an argument - regarding last Thursday's methane gas explosion at the Upper Big Branch mine in West Virginia, that killed 25 adult miners and left another four so far missing - that we've made some progress in protecting children from mine disasters. Our track record in protecting adults is less impressive - that is they…
