MSHA PROGRAM POLICY MANUAL VOLUME V PART 77 MANDATORY SAFETY STANDARDS - SURFACE COAL MINES AND SURFACE WORK AREAS OF UNDERGROUND COAL MINES Subpart C Surface Installations 77.100 Demonstration of Ability to Test for Methane andfor Oxygen Deficiency The demonstration of ability requirement of 30 CFR 77.100 applies when an applicant works at a surface area of an underground mine or a surface mine where there is a need for competence in testing for methane and/or oxygen deficiency. Locations where such tests are required include: Tests for Methane 77.201-1 structures, enclosures, or other facilities where coal is handled or stored; 77.211(b) tunnels located below stockpiles, surge piles, and coal storage silos; 77.1112(b) areas where welding, cutting, or soldering will take place and that are likely to contain methane; 77.1916(c) any slope or shaft designed to penetrate into any coalbed below the surface and where welding, cutting, or soldering is to be performed; Tests for Oxygen Deficiency and Methane 77.1501(c) the collar of auger holes when the auger hole penetrates an abandoned or mined out area of an underground mine; and 77.1901(a) slope and shaft areas. Applicants for temporary certification who work at mines where one or more of the above standards has application are required to demonstrate their ability to competently perform the prescribed test to an MSHA inspector or training specialist. Where none of the circumstances or conditions described by the above standards are present, persons working at such mines and applying for temporary certification are not required to demonstrate their ability to perform methane or oxygen deficiency tests. MSHA inspectors will determine whether a demonstration of ability is necessary on a mine-by-mine basis. A temporary certification under 30 CFR 77.100 applies only to the mine where the miner is employed at the time the temporary certification is granted. February 2003 (Release V-33) 161
MSHA PROGRAM POLICY MANUAL VOLUME V 77.200 Surface Installations; General This Section does not apply to housekeeping. It is to be used for keeping surface facilities in good repair relative to safety. Inspections of surface facilities, structures, and enclosures should include an examination of all load-carrying members and related bracing. When such members or bracing are substantially warped, bent, deteriorated due to corrosion or weathering, or otherwise damaged or missing, the structure may be unstable or have a reduced load-carrying capacity. These conditions can cause or contribute to serious accidents and injuries, and appropriate enforcement action must be taken pursuant to this Section to require the structure, enclosure, or other facility to be maintained in good repair. The district engineering staff should be consulted to evaluate the condition of a surface structure where assistance is needed in determining whether the condition causes instability or reduces the load-carrying capacity of the structure. 77.201 Methane Content in Surface Installations Methane tests are not required where there are no surface structures, enclosures, or other facilities where methane could accumulate; where auger mining is not being conducted; or where tunnels are not located below stockpiles. There may be other conditions that do not require methane tests, in which case the inspector should use good judgment in requiring compliance with this regulation. 77.201-1 Tests for Methane; Qualified Person; Use of Approved Device These tests are required regardless of any other gas detecting methods used. 77.201-2 Methane Accumulations; Change in Ventilation This Section may be used to determine if a ventilation fan is needed for various surface facilities. However, it does not provide the authority to require a fan if other satisfactory adjustments in ventilation can be made. 77.202 Dust Accumulations in Surface Installations This section is not meant to control dust from a health standpoint. It is meant to control dangerous quantities of coal dust that would create a fire or explosion hazard. February 2003 (Release V-33) 162
