As to injured men underground,even fatalities,every man was stretchered out the pit usually by his own Marra's..not necessarily First Aiders like myself..if a man needed Morphia [Morphine],after a serious accident,only a qualified Official [usually the face Deputy],was allowed to administer by injection to the injured person,and only if that person requested it..then whoever administered Morphia,HAD TO...BY LAW..escort the that person to the surface and hand him over to the Ambulance team...after tying a named and dated bracelet to the injured person's wrist. Morphia was kept in securely locked safes built into brickwork in every Deputy's District underground.The Deputy was the ONLY person,other than a Doctor,in any industry in Britain,who was trained and certified by Law,Mines and Quarries Act 1956,to Adminster Morphia by needle injection,when requested by an injured person.That,was the level of responsibility of a Mine Deputy.[UNLESS..a Doctor could reach the injured person within TWO hours..over that time period..the Law would apply..]
