OSHA Compliance
Since insulating links are not yet covered by OSHA standards, no testing laboratory has been recognized as an NRTL for insulating link certification. It will take time to review laboratory applications for recognition, and once NRTLs are established, additional time will be needed for testing. Consequently, §1926.1408(b)(4)(v) will not be available as an additional measure under §1926.1408(b)(4) until NRTL-approved insulating links are available. During this period, employers must follow the requirements in §1926.1408(b)(1)-(3) and implement at least one measure from §1926.1408(b)(4)(i)-(iv). [as of 7-30-2010]
