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. This exception shall not apply where the active working sections are more than 2 miles from the surface.\n\n[35 FR 17890, Nov. 20, 1970, as amended at 73 FR 53127, Sept. 15, 2008]","occurrenceCount":1},{"chapter":"I","chapterHeading":"CHAPTER I—MINE SAFETY AND HEALTH ADMINISTRATION, DEPARTMENT OF LABOR","citation":"30 CFR 75.517","heading":"Power wires and cables; insulation and protection.","id":"75.517","officialUrl":"https://www.ecfr.gov/current/title-30/chapter-I/subchapter-O/part-75/subpart-F/section-75.517","part":"75","partHeading":"PART 75—MANDATORY SAFETY STANDARDS—UNDERGROUND COAL MINES","subchapter":"O","subchapterHeading":"SUBCHAPTER O—COAL MINE SAFETY AND HEALTH","subpart":"F","subpartHeading":"Subpart F—Electrical Equipment—General","text":"[Statutory Provisions]\n\nPower wires and cables, except trolley wires, trolley feeder wires, and bare signal wires, shall be insulated adequately and fully protected.","occurrenceCount":1},{"chapter":"I","heading":"Self-rescue devices; inspection, testing, maintenance, repair, and recordkeeping.","officialUrl":"https://www.ecfr.gov/current/title-30/chapter-I/subchapter-O/part-75/subpart-R/section-75.1714-3","part":"75","subchapter":"O","subpart":"R","id":"75.1714-3","citation":"30 CFR 75.1714-3","chapterHeading":"CHAPTER I—MINE SAFETY AND HEALTH ADMINISTRATION, DEPARTMENT OF LABOR","subchapterHeading":"SUBCHAPTER O—COAL MINE SAFETY AND HEALTH","partHeading":"PART 75—MANDATORY SAFETY STANDARDS—UNDERGROUND COAL MINES","subpartHeading":"","text":null,"occurrenceCount":1},{"chapter":"I","chapterHeading":"CHAPTER I—MINE SAFETY AND HEALTH ADMINISTRATION, DEPARTMENT OF LABOR","citation":"30 CFR 75.1403","heading":"Other safeguards.","id":"75.1403","officialUrl":"https://www.ecfr.gov/current/title-30/chapter-I/subchapter-O/part-75/subpart-O/section-75.1403","part":"75","partHeading":"PART 75—MANDATORY SAFETY STANDARDS—UNDERGROUND COAL MINES","subchapter":"O","subchapterHeading":"SUBCHAPTER O—COAL MINE SAFETY AND HEALTH","subpart":"O","subpartHeading":"Subpart O—Hoisting and Mantrips","text":"[Statutory Provisions]\n\nOther safeguards adequate, in the judgment of an authorized representative of the Secretary, to minimize hazards with respect to transportation of men and materials shall be provided.","occurrenceCount":1},{"chapter":"I","chapterHeading":"CHAPTER I—MINE SAFETY AND HEALTH ADMINISTRATION, DEPARTMENT OF LABOR","citation":"30 CFR 75.1403-6","heading":"Criteria—Self-propelled personnel carriers.","id":"75.1403-6","officialUrl":"https://www.ecfr.gov/current/title-30/chapter-I/subchapter-O/part-75/subpart-O/section-75.1403-6","part":"75","partHeading":"PART 75—MANDATORY SAFETY STANDARDS—UNDERGROUND COAL MINES","subchapter":"O","subchapterHeading":"SUBCHAPTER O—COAL MINE SAFETY AND HEALTH","subpart":"O","subpartHeading":"Subpart O—Hoisting and Mantrips","text":"(a) Each self-propelled personnel carrier should:\n\n(1) Be provided with an audible warning device;\n\n(2) Be provided with a sealed-beam headlight, or its equivalent, on each end;\n\n(3) Be provided with reflectors on both ends and sides.\n\n(b) In addition, each track-mounted self-propelled personnel carrier should:\n\n(1) Be provided with a suitable lifting jack and bar, which shall be secured or carried in a tool compartment;\n\n(2) Be equipped with 2 separate and independent braking systems properly installed and well maintained;\n\n(3) Be equipped with properly installed and well-maintained sanding devices, except that personnel carriers (jitneys), which transport not more than 5 men, need not be equipped with such sanding device;\n\n(4) If an open type, be equipped with guards of sufficient strength and height to prevent personnel from being thrown from such carriers.","occurrenceCount":1},{"chapter":"I","chapterHeading":"CHAPTER I—MINE SAFETY AND HEALTH ADMINISTRATION, DEPARTMENT OF LABOR","citation":"30 CFR 77.1605","heading":"Loading and haulage equipment; installations.","id":"77.1605","officialUrl":"https://www.ecfr.gov/current/title-30/chapter-I/subchapter-O/part-77/subpart-Q/section-77.1605","part":"77","partHeading":"PART 77—MANDATORY SAFETY STANDARDS, SURFACE COAL MINES AND SURFACE WORK AREAS OF UNDERGROUND COAL MINES","subchapter":"O","subchapterHeading":"SUBCHAPTER O—COAL MINE SAFETY AND HEALTH","subpart":"Q","subpartHeading":"Subpart Q—Loading and Haulage","text":"(a) Cab windows shall be of safety glass or equivalent, in good condition and shall be kept clean.\n\n(b) Mobile equipment shall be equipped with adequate brakes, and all trucks and front-end loaders shall also be equipped with parking brakes.\n\n(c) Positive-action type brakes shall be provided on aerial tramways.\n\n(d) Mobile equipment shall be provided with audible warning devices.
