{"abstract":"This final rule establishes MSHA's new mandatory electrical safety standards for the installation, use, and maintenance of high- voltage longwall mining systems used in underground coal mines. The final rule also includes design approval requirements for high-voltage equipment operated in longwall face areas of underground mines. These provisions allow the use of high-voltage longwall face equipment with enhanced safety protection from fire, explosion, and shock hazards. In addition to providing a safer mining environment and facilitating the use of advanced equipment designs, the final rule reduces paperwork requirements by eliminating the need for petitions for modification (variances).","action":"Final rule.","agencies":[{"raw_name":"DEPARTMENT OF LABOR","name":"Labor Department","id":271,"url":"https://www.federalregister.gov/agencies/labor-department","json_url":"https://www.federalregister.gov/api/v1/agencies/271","parent_id":null,"slug":"labor-department"},{"raw_name":"Mine Safety and Health Administration","name":"Mine Safety and Health Administration","id":288,"url":"https://www.federalregister.gov/agencies/mine-safety-and-health-administration","json_url":"https://www.federalregister.gov/api/v1/agencies/288","parent_id":271,"slug":"mine-safety-and-health-administration"}],"body_html_url":"https://www.federalregister.gov/documents/full_text/html/2002/03/11/02-4863.html","cfr_references":[{"chapter":null,"citation_url":null,"part":18,"title":30},{"chapter":null,"citation_url":null,"part":75,"title":30}],"citation":"67 FR 10972","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This regulation is effective May 10, 2002.
