Two portable fire extinguishers and 240 pounds of rock dust, shall be provided at each permanent underground oil storage station. One portable fire extinguisher shall be provided at each working section where 25 gallons or more of oil are stored in addition to extinguishers required under paragraph (a) of this section.\n\n(g) Welding, cutting, soldering. One portable fire extinguisher or 240 pounds of rock dust shall be provided at locations where welding, cutting, or soldering with arc or flame is being done.\n\n(h) Powerlines. At each wooden door through which powerlines pass there shall be one portable fire extinguisher or 240 pounds of rock dust within 25 feet of the door on the intake air side.\n\n(i) Emergency materials. (1) At each mine producing 300 tons of coal or more per shift there shall be readily available the following materials at locations not exceeding 2 miles from each working section:\n\n1,000 board feet of brattice boards 2 rolls of brattice cloth 2 hand saws 25 pounds of 8 d nails 25 pounds of 10 d nails 25 pounds of 16 d nails 3 claw hammers 25 bags of wood fiber plaster or 10 bags of cement (or equivalent material for stoppings) 5 tons of rock dust\n\n(2) At each mine producing less than 300 tons of coal per shift the above materials shall be available at the mine, provided, however, that the emergency materials for one or more mines may be stored at a central warehouse or building supply company and such supply must be the equivalent of that required for all mines involved and within 1-hour's delivery time from each mine.
