COAL MINE SAFETY AND HEALTH GENERAL INSPECTION PROCEDURES HANDBOOK CHAPTER 3 with. A fire extinguisher with a 2-A:10-B:C designation that contains approximately 4.25 pounds of dry powder meets the intent of the standard and provides an acceptable level of protection. Also refer to the National Fire Protection Association ® (NFPA) Nos. NFPA 11A 1970 - High Expansion Foam Systems, NFPA 13 1969 - Installation of Sprinkler Systems, NFPA 13A 1971 - Care and Maintenance of Sprinkler Systems, NFPA 15 1969 - Water Spray Fixed Systems for Fire Protection, NFPA 17 1969 - Dry Chemical Extinguishing Systems, NFPA 72A 1967 - Local Protective Signaling Systems or NFPA 198 1969 - Care, Maintenance and Use of Fire Hose. The electronic NFPA documents hyperlinked are being provided to serve as an additional resource to the hard copies you received previously. Do not distribute copies of these codes to non-MSHA persons, mines, and companies, because they are copyrighted by the NFPA. Again, it is being stressed that these are copyrighted documents and we have acquired them for only MSHA. Any further distribution outside of MSHA is a violation of MSHA’s license. (Refer to Fire Extinguishers: 73 Fed. Reg. 53124 (Sept. 15, 2008) for additional information.) Documentation Required: Inspection of specialty or standalone fire protection equipment should be documented in the inspection notes to show the location and type of fire protection provided. For the purpose of documentation for all handheld portable fire extinguishers associated with protection for a designated piece of equipment or a designated location shall be considered inspected with that piece of equipment or designated location and does not require separate documentation. 8. First-Aid Equipment. An inspection shall be conducted of all underground working sections first-aid equipment for compliance with applicable standards. 9. Health and Safety Discussions. The inspector shall discuss matters concerning health and safety and work practices with the miners during inspection activities on a working section, including recent accidents, accident history, mine-specific hazards, and occupation-specific health and safety concerns. To reinforce inspection and documentation elements related to ventilation plans, enforcement personnel should conduct the specific activities below. These activities are in addition to any other activities that are deemed necessary as part of their E01 Regular Safety and Health Inspections or during E21 Ventilation Technical Investigations by ventilation specialists.

COAL MINE SAFETY AND HEALTH GENERAL INSPECTION PROCEDURES HANDBOOK CHAPTER 3 a. Discuss and question miners on current mining activities and conditions. Question the miners to determine whether their training with respect to the ventilation plans is complete and adequate for the mining activities. Ten example questions are listed below. These or other questions may be asked to determine the miners’ level of knowledge. These discussions should be documented. 1) Were you trained on the contents of the ventilation plan? 2) Do you know how far the ventilation control device set back should be? 3) What is the required air quantity at the end of the ventilation control device? 4) What is the scrubber quantity (if applicable)? 5) What is required quantity at the last open cross cut? 6) What are the required quantity and/or velocity at the headgate? 7) What are the required quantity and/or velocity at the tailgate? 8) How often are you required to take gas checks? 9) Do you know what to do if the machine mounted methane monitor reaches 1%, 1.5%, or 2%? 10) Is belt air allowed to be used at the face? b. All ventilation plans are to be reviewed on a six month basis, and necessary documentation of the plan reviews and evaluations, including MSHA Form 2000-204, is to be included with the E01 inspection report or the E21 investigation report. c. Assistance may be requested from MSHA’s Educational Field Services (EFS) to evaluate training on retreat mining. These measures should serve to strengthen our inspection efforts to ascertain the adequacy of ventilation plans and to determine the effectiveness of miner training concerning ventilation plans. (Refer to Accident Rep: 74 Fed. Reg. 68918 (Dec. 29, 2009) and Part 50: 75 Fed. Reg. 21990 (April 27, 2010) for additional information.) Documentation Required: Health and safety discussions by the inspector should be documented in the inspection notes to show the mechanized mining unit number. Also a general statement about the discussion held with a representative number of miners for each MMU inspected about current mining activities and conditions, and training with respect to the ventilation plans is adequate will suffice.
