Mine rescue teams compete in contests across the country to prepare themselves to operate effectively in a mine emergency Provide or view comments on MSHA regulations to repeal, replace or modify Read submitted comments or provide new comments under EO 13777, enforcing the regulatory reform agenda.

Handbook for Methane Control in MiningProper ventilation plays the major role in keeping mines free of hazardous methane accumulations The ventilation discussed in this handbook, except for the chapter on bleeder systems, deals only with so called face ventilation, ie, ventilation of the immediate working face area, not ventilation of the mine.Underground mine ventilationUnderground mine ventilation provides a flow of air to the underground workings of a mine of sufficient volume to dilute and remove dust and noxious gases (typically NO x, SO 2, methane, CO 2 and CO) and to regulate temperature The source of these gases are equipment that runs on diesel engines, blasting with explosives, and the orebody itself.Equipment Approval & CertificationFederal regulations require the approval or certification of certain mining products for use in underground coal and gassy underground metal min Technical experts from MSHA’s Approval and Certification Center (A&CC) evaluate and test equipment, instruments, and materials for compliance Products evaluated and tested range from small electronic devices to large mining.Hazardous Areas ClassificationDivision Probability of Hazardous Material; Division 1 The substance referred to by class has a high probability of producing an explosive or ignitable mixture due to it being present continuously, intermittently, or periodically or from the equipment itself under normal operating conditions.Hazardous Area Classification and Control of Ignition SourcesHazardous Area Classification and Control of Ignition Sourc This Technical Measures Document refers to the classification of plant into hazardous areas, and the systematic identification and control of ignition sourc The relevant Level 2 Criteria are 5213(29)c, 52111(63)f, 52113 and 5242(93)a.DEMYSTIFYING EQUIPMENT DESIGN IN HAZARDOUSDEMYSTIFYING EQUIPMENT DESIGN IN HAZARDOUS LOCATIONS Rockwell Automation Fair , •NEC 500 North American Standards & Certifications •Class & Division / Sub Group / Temperature Class •NEC 505 AEx •IEC & ATEX Standards & Certifications •Zones / Protection Concepts / Temperature Class , Equipment Group 1
