Lead wires shall not be connected to the blasting switch until the shot is ready to be fired.\n\n(jj) The key or other control to an electrical firing device shall be entrusted only to the person designated to fire the round or rounds.\n\n(kk) If branch circuits are used when blasts are fired from power circuits, safety switches located at safe distances from the blast areas shall be provided in addition to the main blasting switch.\n\n(ll) Misfires shall be reported to the proper supervisor and shall be disposed of safely before any other work is performed in that blasting area.\n\n(mm) When safety fuse has been used, men shall not return to misfired holes for at least 30 minutes.\n\n(nn) When electric blasting caps have been used, men shall not return to misfired holes for at least 15 minutes.\n\n(oo) If explosives are suspected of burning in a hole, all persons in the endangered area shall move to a safe location and no one should return to the hole until the danger has passed, but in no case within 1 hour.\n\n(pp) Blasted areas shall be examined for undetonated explosives after each blast and undetonated explosives found shall be disposed of safely.\n\n(qq) Blasted areas shall not be reentered by any person after firing until such time as concentrations of smoke, dust, or fumes have been reduced to safe limits.\n\n(rr) In secondary blasting, if more than one shot is to be fired at one time, blasting shall be done electrically or with detonating cord.\n\n(ss) Unused explosives and detonators shall be moved to a safe location as soon as charging operations are completed.\n\n(tt) When electric detonators are used, charging shall be stopped immediately when the presence of static electricity or stray currents is detected; the condition shall be remedied before charging is resumed.\n\n(uu) When electric detonators are used, charging shall be suspended and men withdrawn to a safe location upon the approach of an electrical storm.","occurrenceCount":2},{"chapter":"I","chapterHeading":"CHAPTER I—MINE SAFETY AND HEALTH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.
