AND JOURNAL OF THE COAL AND IRON TRADES. Vol. CVII. THURSDAY. APRIL 9, 1914. No. 2780? Training of Rescue Brigades. THE NORTH STAFFORDSHIRE COALOWNERS’ STATION. At a meeting of the North Staffordshire Institute of Mining and Mechanical Engineers on Monday, Mr. G. H. Greatbatch read a paper on the “ Training of .Rescue Brigades at the North Staffordshire Coalowners’ Central Resue Station at the Berry Hill Colliery, Stoke-on- Trent.” He said:— The station consists of a large room in which is stored the breathing apparatus, &c., an adjoining smoke gallery in which the men are trained, and, a few yards distant, another room fitted with washing accommodation, in which the men change their clothes. The gallery is not an ideal one for the purpose, and plans are being prepared for a permanent, up-to-date building, but at the same time I do claim that the men have been trained in a very efficient manner and have accomplished rescue and recovery work with the apparatus in the North Staffordshire coalfield, which, up to the present, constitutes a record for the United Kingdom. The breathing apparatus installed is the well-known Fleuss-Davis “ Proto ” self-contained type, and the reviving apparatus used is the “ Proto,” both of which are manufactured by Messrs. Siebe, Gorman and Co. Limited, London. The equipment of the station is well in excess of what is required to comply with the Rescue and Aid Order, and a supply of oxygen cylinders, charging-pump, caustic soda, all necessary spare parts, and birds are kept in stock. In the colliery yard a motor van is housed, ready for immediate despatch to the scene of any disaster. It is equipped with 12 complete sets of apparatus, fully charged; three 100 cubic feet capacity oxygen cylinders, oxygen pump, 1 cwt. of caustic soda, electric lamps, reviving apparatus, ambulance box and a quantity of spare parts. The motor van is taken out each week for a short run to keep it in order, and the whole of the 12 sets of apparatus are changed weekly. Telephonic communication is established between the instructor’s house and the rescue station at the colliery, and arrangements have been made with the district superintendent to have priority of calls. The staff consists of an instructor and assistant instructor. The brigades are selected from volunteers by the managers of the individual collieries, and before being sent for training are subjected to a very strict and searching medical examination. Unless they are abso- lutely physically fit they are not accepted. We have found this to be a very necessary precaution, and in addition each man is informed that if he is suffering from cold, or any other slight derangement, it is much better to miss a practice, as the work is too serious to run any risks. I am absolutely certain that men working strenuously each day, and consequently in good hard working condition, are able to wear the apparatus with less fatigue, and consequently less fear of a breakdown, than a man who is in what I call a soft condition. Each brigade consists of six men, No. 1 man acting as leader and No. 6 man as captain. The training consists of 12 practices at the station, each of two hours’ duration—one practice per week for 12 consecutive weeks. First Practice.—This is wholly occupied by the in- structor’s thorough explanation of the apparatus, and by marching round the station wearing the mouthpiece only, which is called “ mouth drill.” Second Practice.—The complete apparatus is worn and the men merely walk about the station. Third Practice.—The men wearing the apparatus are put into the gallery and do a limited amount of work. Foztrth Practice.—The men work in the gallery for the first 45 minutes, and then sulphur fumes, not strong, are turned in for the remainder of the practice. Fifth Practice.—The whole of the work is done in the gallery filled with strong sulphur fumes, and the pro- gramme of work at this and the remainder of the practices is as follows :— A weight of 56 lb. is pulled to a height of 8 ft. ten times by each member of the team. Bricks are loaded in a wagon, pushed along a tramway, and a stopping built on an upper platform. This is then taken down, and the bricks taken back to their original position. Three settings of timber are fixed and covered with brattice cloth, and a dummy is placed on a stretcher and carried through them. The men are taught to creep through small apertures, pushing the breathing bag in front of them. Wooden blocks are carried, and a stop- ping built in a confined space—in fact, the practice is as near alike to actual pit work as it is possible to make it. Previous to each day’s training, the instructor explains to the men how to proceed in the different circum- stances they may be placed in during actual work down a mine. The men are taught to put on tbe apparatus expe- ditiously and without assistance, and to test its condition. Leakages of oxygen from the valves and cylinders can be detected by smearing soapy water round them, and if there is a leakage, bubble will be formed. Another way is to apply the glowingendof a match, which, in contact with oxygen, will burst into flame. A person with quick hearing may detect a slight hissing sound. A captain should examine the valves and connections of each appa- ratus worn by members of his team, to see that they are in proper order, also to registei’ the pressure of oxygen shown on the gauge. Each man, before putting on the nose-clip, should also make sure the oxygen is entering the breathing bag. This may be done by slightly bending the head and listening near the main oxygen tube, when, if the passage is clear, oxygen will be heard flowing through. He should take several short and sharp breaths to ensure that the inhaling and exhaling valves are loose and in order. The relief valve should also be tested for airtightness. Before putting on the nose-clip the wearer should inhale through the nose several times, and exhale through the mouth, until the bag is about three-parts full of air. The inhaling tube should then be gripped tightly above the valve and pressure put on the breathing bag with the other hand, when any leakage will be heard and felt. At the termination of the training, colliery managers are appointed to examine thoroughly the men in their work and the description and use of various parts of the apparatus, and also as to how they would proceed in actual rescue work down a mine after a disaster. They are also examined with regard to the building off of workings affected by gob stink, and no man is certifi- cated until efficient. Up to December 31, 1913, we have fully trained and passed for certificates 418 men, and during the training of this number and the few that fell out the following incidents have occurred :— In Connection with the Main Valve. August 4, 1911: The leader of a brigade turned off his oxygen supply whilst walking round the apparatus room and collapsed. On reviving he remarked: “If dying is as easy as that, then I am not afraid to die.” September 8, 1911: No. 5 man of a brigade collapsed in the gallery from the same cause. When brought round, he charged one of his mates with pushing him down. It appears when he was falling he tumbled against him. November 3, 1911: The captain of a team, when breathing oxygen for the first time, and naturally taking .it easy, was troubled by his bag filling. He turned off his main valve, instead of pressing the relief valve, and in a few minutes became unconscious. Coming round, his first words were : “ What am I doing here?” February 16, 1912 : A member of a brigade turned off the main valve in the gallery, and when collapsing grazed his arm. He was brought round in the fumes by the other members of the team. August 12, 1912: Two men, belonging to the same --’am, turned off their main valves and collapsed in the apparatus room, but quickly came round. Before falling, the face of one became a curious green colour. February 25,1913: When building the block stopping- under the staging, one of a team collapsed through shortage of oxygen, owing to the main valve being accidentally, closed. The captain, a man holding a first- class certificate, at once tried the main valve and found it shut. He opened it, turned on the by-pass, and in a short time brought the unconscious man round without bringing him out of the fumes. . Great credit was due to the captain for the able and cool manner in which he dealt with this emergency. The instructor was watching the occurrence through the window. . May 6, 1913 : When working in the gallery, a captain turned his valve spindle completely out, losing all his oxygen in a few seconds. Several cases have occurred in the gallery where the main valve has been accidentally closed, but these have been noticed immediately and no ill-effects caused. Sticky Bags. December 2, 1911: No. 4 man in a brigade had to come out of the gallery with a sticky bag, after 1 hour 45 minutes’ work. January 8,1912 : No. 5 man in a brigade had to come out with a sticky bag, after 1 hour 50 minutes’ work. February 13, 1912: No. 5 man in a team had to retire with a sticky bag a few minutes before time. It was the third time he had used oxygen. The following week he finished his practice, but his soda was in a very sticky condition. The fifth week he used his by-pass often and had to come out again, because his bag was sticky, and he could not get a circulation. This was his last practice. The foregoing occurred when we were using a large proportion of caustic soda obtained from the Continent, and not from the, firm who are now supplying the association with their requirements. Breathing Fumes. August 20, 1912 : A leader of a team came out of the gallery complaining that he was breathing the sulphur fumes. It was found that in putting on the mouthpiece he had allowed a portion of his moustache to get between the rubber and his lips, and the fumes were being inhaled through the opening so caused. Saliva Trap. July 19, 1912: A rescue man’s saliva trap became disconnected after 1 hour 25 minutes’ work in the gallery. He came out and had it replaced. Had it occurred in the pit, it could have been replaced quite as easily without any ill-effect. Damaged Breathing Bag. In the gallery a man, throwing a piece of timber with a jagged end, caught his canvas bag and punctured it also the rubber breathing bag. No ill-effects occurred, but if such an accident happened whilst doing actual rescue work in an irrespirable atmosphere, a man would be in an awkward fix, unless be had the presence of mind to close the perforation by holding the torn ends close together with his hand, and come out immediately. Over-exertion. January 15, 1912 : A brigade, whilst being examined, went through their work very slowly, and No. 2 man being anxious to get the work done, over-exerted himself, and had to be assisted out of the gallery. His lips turned purple. This was after two hours’work. The others continued working. Presently the leader informed the captain that he was short of oxygen. The latter examined the man’s gauge, and in mistake turned on fully the by-pass valve, instead of the gauge valve. In consequence, the breathing bag was blown up hard, the nose-clip was forced off, and the mouthpiece would undoubtedly have been blown out had it not been securely strapped. This would have been very serious had it occurred in a mine in an irrespirable atmosphere. The work was completed in 2 hours 25 minutes. January 3, 1912 : During the examination of a brigade No. 4 man over-exerted himself, came out of the gallery for 5 minutes, then returned and finished the work with the others. In connection with the main valve getting accidentally closed, the following occurred at Norton during the recovery of the .pit:—
