GENERAL COAL MINE INSPECTION PROCEDURES AND INSPECTION TRACKING SYSTEM HANDBOOK CHAPTER 4 underground area of the mine does not carry smoking materials, matches, or lighters. 13. Advise company officials to alert mine rescue teams, doctors, and hospitals, if needed. 14. Advise company officials that current mine maps or prints will be needed. 15. If another MSHA employee is not present at the mine, request that company officials assign someone on the surface to maintain a log of all rescue and recovery activities. As soon as another MSHA employee is available, he or she shall be assigned to maintain a separate log for MSHA. 16. After the above surface tasks have been completed, proceed underground if this can be done safely, to monitor the firefighting and rescue/recovery operations and look for additional information and causes. If two MSHA personnel are dispatched to the emergency site, one may proceed directly underground, if this can be done safely. 17. Relay all pertinent information to an MSHA person on the surface who shall relay this information to the District Office. 18. Upon arrival underground, check returns for methane, carbon monoxide, and other gases if this can be done safely and advise company officials to assign persons to continuously sample the returns and report the results. 19. All MSHA personnel shall keep complete notes on all activities performed in their work assignments. All such notes shall be submitted to the District Manager or other designated District official. 20. Report all gas readings and mine conditions to the MSHA person in charge of the log, and keep a record of time, location, and gas readings in a notebook. Make sure that the gas detecting devices are accurate. (Refer to MSHA Form 7000-10A for pocket card information and Headquarters Mine Emergency Response Guidelines Handbook.) U. Use of 103 (j) and (k) orders. As specified in Item T.1 above, on learning of a mine emergency, as soon as possible, MSHA shall issue a 103(j) or (k) order (depending on whether or not an inspector is present at the mine site) to the operator along with Release 1 (February 2013) 4-22
GENERAL COAL MINE INSPECTION PROCEDURES AND INSPECTION TRACKING SYSTEM HANDBOOK CHAPTER 4 initial instructions. The order should be reduced to writing and served to the operator as quickly as practical. The order should be written so as to protect all persons engaged in the rescue and recovery operation as well as any other persons on site, and reduce the potential for miscommunication. Parties on site should be informed that any activities will be permitted through subsequent modifications of the 103(k) order. The 103(k) order is intended to protect all persons involved in the emergency operation. As such, all parties on site are subject to the 103(k) order and its subsequent modifications. Each proposed action should be reviewed by the designated senior MSHA person on site before the 103(k) order is modified and before the action is commenced. Even though the 103(k) order is controlling, consistent with federal primacy, every effort should be made to gain consensus among the parties present in the command center to obtain the safest most effective outcome. (Refer to Accident/Illness Investigation Procedures Handbook for further guidance.) First Response Air Sampling Units: In addition to following the above guidance, the first MSHA personnel arriving on site should establish baseline air quality readings at the main return or exhaust fan after a mine fire or explosion has occurred. The following items for the units will be maintained in each district and field office, except where field offices are located within the same building as the district office: a. 115 volt AC Vacuum Pump b. Flame arrester c. Two 500 ft. Rolls of ¼ -inch inside diameter vinyl tubing d. ATX-620 Multi-gas Detector with IR Sensor or equivalent e. Tubing connectors These air sampling units will permit MSHA to set up a system to monitor the atmosphere from a safe location at specific mine locations such as a mine fan or an exhaust entry. As a first response system for monitoring air, it is envisioned that MSHA personnel will place the vinyl tubing at a mine fan or inside an exhaust entry and then run the tubing to a location that will not subject personnel to potentially high concentrations of carbon monoxide (CO) or methane (CH4). The vacuum pump will be attached to the tubing and operated by connecting to a 110 volt electrical source at the mine site. Connecting the vacuum pump, tubing, flame arrester and the ATX-620 detector or equivalent detector in the manner shown on the attached sketch will permit MSHA personnel to monitor the mine atmosphere until additional mine emergency equipment is available. In addition, it will be necessary to collect a bag sample for documentation of the mine air for analysis by Technical Support or MSHA’s Air Lab. At least on an hourly basis, a bag sample will be collected and Release 1 (February 2013) 4-23
