The Minimum Approach Distance (MAD) is the distance qualified workers have to stay away from energized conductors when unprotected. What is Minimum Approach Distance? Who can work within the MAD? See OSHA’s memorandum on this new enforcement date change. If peer-reviewed guidance regarding the calculation of maximum transient overvoltages is not available before May 1, 2016, OSHA will extend this policy as necessary to give employers time to read and implement such guidance when it becomes available. 960(c)(1)(ii), which require the employer to determine the maximum anticipated per-unit transient overvoltage, provided the employer assumes a maximum anticipated per-unit transient overvoltage, phase-to-ground, of 3.0 per unit. Until January 31, 2017, for voltages of 72.6 to 169.0 kilovolts, no citations will be issued under. 960(c)(1)(ii), which require the employer to determine the maximum anticipated per-unit transient overvoltage and (ii) OSHA will accept compliance with the minimum approach distances in Table 6 or Tables 10 to 13 in Appendix B to. Until January 31, 2017, for voltages of 169.1 kilovolts and more: (i) no citations will be issued under.
