The device must be located as close as practicable to the battery terminals and be designed to operate within its electrical rating without damage. The device shall not automatically reset after being actuated. All magnetic circuit-interrupting devices must be mounted in a manner to preclude their closing by force of gravity;\n\n(e) Each motor and charging generator must be protected by an automatic overcurrent device. One protective device will be acceptable when two motors of the same rating operate simultaneously and perform virtually the same duty;\n\n(f) Each ungrounded conductor must have insulation compatible with the impressed voltage. Insulation materials must be resistant to deterioration from engine heat and oil. Electric conductors must meet the applicable requirements of §§ 75.513 and 75.513-1, except electric conductors for starting motors, which must only meet the requirements of § 75.513;\n\n(g) All wiring must have adequate mechanical protection to prevent damage to the cable that might result in short circuits;\n\n(h) Sharp edges and corners must be removed at all points where there is a possibility of damaging wires, cables, or conduits by cutting or abrasion. The insulation of the cables within a battery box must be protected against abrasion;\n\n(i) When insulated wires other than cables pass through metal frames, the holes must be substantially bushed with insulated bushings. Cables must enter metal frames of motors, splice boxes, and electric components only through proper fittings. All electrical connections and splices must be mechanically and electrically efficient, and suitable connectors shall be used. All electrical connectors or splices in insulated wire must be reinsulated at least to the same degree of protection as the remainder of the wire;\n\n(j) The battery must be secured to prevent movement, and must be protected from external damage by position. Batteries that are not protected from external damage by position must be enclosed in a battery box. Flame-resistant insulation treated to resist chemical reaction to electrolyte must be provided on battery connections to prevent battery terminals from contacting conducting surfaces;\n\n(k) A battery box, including the cover, must be constructed of steel with a minimum thickness of 1/8 inch, or of a material other than steel that provides equivalent strength;\n\n(l) Battery-box covers must be lined with a flame-resistant insulating material permanently attached to the underside of the cover, unless equivalent protection is provided. Battery-box covers must be provided with a means for securing them in closed position. At least 1/2 inch of air space must be provided between the underside of the cover and the top of the battery, including terminals;\n\n(m) Battery boxes must be provided with ventilation openings to prevent the accumulation of flammable or toxic gases or vapors within the battery box. The size and locations of openings for ventilation must prevent direct access to battery terminals;\n\n(n) The battery must be insulated from the battery-box walls and supported on insulating materials. Insulating materials that may be subject to chemical reaction with electrolyte must be treated to resist such action; and\n\n(o) Drainage holes must be provided in the bottom of each battery box.","occurrenceCount":1},{"chapter":"I","heading":"Reporting SCSR inventory and malfunctions; retention of SCSRs.","officialUrl":"https://www.ecfr.gov/current/title-30/chapter-I/subchapter-O/part-75/subpart-R/section-75.1714-8","part":"75","subchapter":"O","subpart":"R","id":"75.1714-8","citation":"30 CFR 75.1714-8","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 77.1110","heading":"Examination and maintenance of firefighting equipment.","id":"77.1110","officialUrl":"https://www.ecfr.gov/current/title-30/chapter-I/subchapter-O/part-77/subpart-L/section-77.1110","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":"L","subpartHeading":"Subpart L—Fire Protection","text":"Firefighting equipment shall be continuously maintained in a usable and operative condition.
