(b) The employer determines that, after consultation with the utility owner/operator, it is infeasible to deenergize and ground the power line or relocate the power line. OSHA Minimum Approach Distance* (OSHA 1926.1408 Table A) 0 to 50kV: 10 feet: Over 50kV to 200kV: 15 feet: Over 200kV to 350kV: 20 feet: Over 350kV to 500kV: 25 feet: Over 500kV to 750kV: 35 feet *Minimum distance for travel under power lines must comply with OSHA … For voltages up to 72.5 kV, the default distances are the same as proposed. Refer to §1926.552(c)(14)(iii) of this part for design factors for wire rope used in personnel hoists. OSHA Subpart V •Minimum Approach Distances and Insulation •Minimum approach distance revisions were effective April 1, 2015. Paragraph (c)(1) of this section does not apply to work covered by Subpart V of this part; instead, for such work, the minimum approach distances established by the employer under § 1926.960(c)(1)(i) apply. — 1926.1408 (c) Use Table A to determine the crane’s Minimum Approach Distance (MAD) to the power line. OSHA provides a minimum approach distance calculator on its website and in the standard. also be trained in minimum approach distances and how to maintain them. The design factor shall be calculated by dividing the breaking strength of wire rope, as reported in the manufacturer's rating tables, by the total static load, including the weight of the wire rope in the shaft when fully extended. 2. 1910.269 and 29 CFR 1926 Subpart V where revised. If the worksite is at an elevation of more than 900 meters (3,000 feet), see footnote 1 to Table 2940.2-4. Ask the utility owner or utility operator for the information. OSHA Rule for Cranes and . •Protection from Flames and Electric Arc Hazards •The employer must assess the workplace to identify workers exposed to flame or Employer must establish minimum approach distances based on formulas in the standard. 75, No. There are three existing voltage-based approach boundaries, and now an arc ... 1910.301-399 (Subpart S), OSHA 1926.400-449 (Subpart K), and OSHA 1926.950-960 (Subpart V), so that the … OSHA 29 CFR 1926 SUBPART CC Rev1010 DRAFT. Allow two working days for a response. (c) Minimum clearance distance. (a) The employer determines that it is infeasible to do the work without breaching the minimum approach distance under Table A of 1926.1408. The revised rules included requirements for employers to establish Minimum Approach Distances. 2 Employers may use the minimum approach distances in Table 2940.2-4 except that the employer may not use the minimum approach distances in Table 2940.2-4 for phase-to-phase exposures if an insulated tool spans the gap or if any large conductive object is in the gap.

For voltages exceeding 72.5 kV, the distances are based on the equations used to calculate the proposed distances (D = TOV × (C + a) + M).
