Applicable Mining Laws

Federal Mine Safety and Health Act of 1977 (the Act)Formed the Mine Safety and Health Administration (MSHA)

Purpose:Establish mandatory health and safety standards to protect the Nation’s miners

Require each mine operator to comply with standards

Improve and expand research and development and training programs aimed at preventing accidents and illnesses.

Mine Improvement and New Emergency Response Act of 2006 (MINER Act)

Required changes in mine emergency response capabilities including communications, tracking, and breathable air.

Testing by Applicant or Third Party(30 CFR Part 7)

Only available for certain products for which test results are non-subjective.

Applicant submits certified statements that product has met test requirements

Products under Part 7 include:Explosion-proof motorsFlame resistant cablesMine Ventilation Controls (Brattice cloth and ventilation tubing)Battery AssembliesDiesel Engines and Diesel Power PackagesRefuge Alternatives

Page 14: UN ECE Sectoral Initiative on Equipment for Explosive Atmospheres 7 September 2011 United States Department of Labor Mine Safety and Health Administration

Testing by Applicant or Third Party(30 CFR Part 7)

MSHA Investigation Consists of:

Verification of:Construction requirements

Quality assurance requirements

Demonstrated test facility competency

Review of:Certified statements

Test results

Page 15: UN ECE Sectoral Initiative on Equipment for Explosive Atmospheres 7 September 2011 United States Department of Labor Mine Safety and Health Administration

30 CFR Part 6

Testing and Evaluation by Independent Laboratories and non-MSHA product safety standards

Promulgated in 2003

Permits MSHA to:Accept test and evaluation results from independent laboratories if they verify compliance with MSHA requirements

Accept equipment designed to non-MSHA product safety standards if MSHA deems such standards to provide at least the same degree of protection as MSHA requirements or determines that such standards can be modified to provide the same degree of protection

Page 16: UN ECE Sectoral Initiative on Equipment for Explosive Atmospheres 7 September 2011 United States Department of Labor Mine Safety and Health Administration

30 CFR Part 6 Equivalency Determination Process

MSHA announces intent to review non-MSHA product safety standard in the Federal Register for purpose of soliciting public input

60 day comment period

MSHA conducts equivalency determination and publishes final determination with any necessary modifications in the Federal Register

The accepted standard is incorporated into 30 CFR with any necessary modifications

Page 17: UN ECE Sectoral Initiative on Equipment for Explosive Atmospheres 7 September 2011 United States Department of Labor Mine Safety and Health Administration

MSHA Part 6 Activities

Completed evaluation of IEC 60079-0 and -1 and determined modification (deviation) is required to ensure equivalent protection to MSHA approval requirements

Evaluation of IEC 60079-0 and -11 has been found to be difficult and is on-going

Participation on IEC TC31 main committee and subcommittees

MSHA has approved several products based on independent laboratory test reports

Page 18: UN ECE Sectoral Initiative on Equipment for Explosive Atmospheres 7 September 2011 United States Department of Labor Mine Safety and Health Administration

Obstacles to MSHA Acceptance of IECEx

1977 Mine Act requirement: “No mandatory health or safety standard promulgated under this title shall reduce the protection afforded miners by an existing mandatory health or safety standard.”

MSHA must be able to show that any new standard provides at least the same degree of protection as existing requirements

Difficulty of comparing IEC standards with MSHA requirements

It’s not “are they safe enough” but rather “are they equally safe”

Page 19: UN ECE Sectoral Initiative on Equipment for Explosive Atmospheres 7 September 2011 United States Department of Labor Mine Safety and Health Administration

Obstacles to MSHA Acceptance of IECEx

Must go through the US rulemaking process before changes to MSHA regulations can be made.

United Mine Workers of America (UMWA) have opposed efforts to harmonize MSHA requirements with the international community.

MSHA resources and priorities.
