Changes or adjustments shall be made to reduce the concentration of methane to less than 1 percent; to reduce the concentration of carbon dioxide to 1 percent or less and excursions not exceeding 2.5 percent; and to reduce the concentration of carbon monoxide to 25 ppm or less. Oxygen shall be maintained at 18.5 to 23 percent.\n\n(j) Refuge alternatives shall contain a fire extinguisher that—\n\n(1) Meets the requirements for portable fire extinguishers used in underground coal mines under this part;\n\n(2) Is appropriate for extinguishing fires involving the chemicals used for harmful gas removal; and\n\n(3) Uses a low-toxicity extinguishing agent that does not produce a hazardous by-product when activated.\n\n[73 FR 80698, Dec. 31, 2008]","occurrenceCount":1},{"chapter":"I","chapterHeading":"CHAPTER I—MINE SAFETY AND HEALTH ADMINISTRATION, DEPARTMENT OF LABOR","citation":"30 CFR 75.1100-2","heading":"Quantity and location of firefighting equipment.","id":"75.1100-2","officialUrl":"https://www.ecfr.gov/current/title-30/chapter-I/subchapter-O/part-75/subpart-L/section-75.1100-2","part":"75","partHeading":"PART 75—MANDATORY SAFETY STANDARDS—UNDERGROUND COAL MINES","subchapter":"O","subchapterHeading":"SUBCHAPTER O—COAL MINE SAFETY AND HEALTH","subpart":"L","subpartHeading":"Subpart L—Fire Protection","text":"(a) Working sections.
