Questions & Answers

Under Appendix G to Subpart V of Part 1926, does following a listed national consensus standard automatically mean I comply with Subpart V requirements?

No — following a listed national consensus standard does not automatically mean you comply with Subpart V. Appendix G says the listed standards "can be helpful in understanding and complying with" Subpart V, but it also states that OSHA "will not necessarily deem compliance with the national consensus standards to be compliance with the provisions of Subpart V." See Appendix G to Subpart V of Part 1926 for the explanatory text.

  • In practice, you can use the consensus standards as detailed, recognized guidance, but you must still meet the specific performance and requirement language in Subpart V itself.

Regarding ANSI/SIA A92.2-2009 listed in Appendix G, can I use that standard to select and inspect vehicle-mounted elevating and rotating aerial devices for my crew?

Yes — ANSI/SIA A92.2-2009 is listed in Appendix G as a recognized national consensus standard for vehicle-mounted aerial devices and can be used as a detailed reference for selection and inspection. Appendix G lists ANSI/SIA A92.2-2009 among standards that "contain detailed specifications that employers may follow" to meet Subpart V's performance-based requirements; however, following it alone does not automatically satisfy OSHA requirements. See Appendix G to Subpart V of Part 1926 for the reference.

  • Use the ANSI standard for equipment criteria, maintenance, and inspection procedures, and verify that your practices also meet the specific obligations in Subpart V.

Under Appendix G to Subpart V of Part 1926, is NFPA 70E-2012 an acceptable reference for electrical workplace safety and arc-flash protection?

Yes — NFPA 70E-2012 is listed in Appendix G and may be used as a recognized guide for electrical safety and arc-flash protection, but it is not automatically an OSHA-approved compliance method. Appendix G includes NFPA 70E-2012 among the listed consensus standards that can help employers comply with Subpart V, but it also clarifies OSHA will not necessarily consider compliance with those standards as compliance with Subpart V. See Appendix G to Subpart V of Part 1926.

  • Use NFPA 70E for practical procedures (risk assessment, arc-flash calculations, PPE selection) and ensure those procedures also meet any specific Subpart V requirements.

Regarding insulating gloves, what does Appendix G list and can I use ASTM D120-09 to determine glove requirements on the job?

Yes — Appendix G lists ASTM D120-09 (Standard Specification for Rubber Insulating Gloves) and you can use it to determine specifications and testing criteria for insulating gloves, though that does not automatically satisfy OSHA. Appendix G identifies ASTM D120-09 as a detailed specification employers may follow to comply with the performance-based requirements of Subpart V, but OSHA also notes compliance with listed consensus standards will not necessarily equal compliance with the subpart. See Appendix G to Subpart V of Part 1926.

  • Use ASTM D120 for selecting class of glove, testing intervals, and care recommendations; document that your glove program addresses both ASTM guidance and any applicable Subpart V duties.

Under Appendix G to Subpart V, are standards for rubber insulating blankets and covers provided so we can follow their specifications? (For example ASTM D1048-12 and ASTM D1049-98)

Yes — Appendix G lists ASTM D1048-12 for rubber insulating blankets and ASTM D1049-98 for rubber insulating covers, and you may follow their specifications as practical guidance for selection and care. The appendix states these national consensus standards "contain detailed specifications that employers may follow," but reminds that following them does not automatically equal compliance with Subpart V. See Appendix G to Subpart V of Part 1926.

  • Use the ASTM standards for product selection, testing, and in-service care procedures, and ensure those practices meet Subpart V obligations.

Regarding temporary protective grounds on de-energized lines, can I follow ASTM F855-09 as listed in Appendix G to meet grounding procedures?

Yes — Appendix G includes ASTM F855-09 (Standard Specifications for Temporary Protective Grounds), and you can use it as authoritative guidance for temporary grounding practices, but it does not automatically make you compliant with OSHA. Appendix G presents ASTM F855-09 as a detailed specification employers may follow to satisfy Subpart V's performance requirements, while cautioning that compliance with the consensus standard may not be treated by OSHA as full compliance with the subpart. See Appendix G to Subpart V of Part 1926.

  • Follow ASTM F855-09 for selection and installation of grounds, and document how the grounding procedures align with Subpart V requirements.

Under Appendix G, can we rely on ASTM F711 and F712 for live-line tool selection and testing?

Yes — Appendix G lists ASTM F711-02 for FRP rod and tube used in live-line tools and ASTM F712-06 for insulating plastic guard equipment, so you can rely on those standards for specifications and test methods, but that reliance does not automatically satisfy Subpart V. Appendix G identifies these ASTM standards as detailed specifications employers may follow, but reiterates OSHA may not necessarily deem compliance with them to equal compliance with the regulatory requirements. See Appendix G to Subpart V of Part 1926.

  • Use these ASTM documents for procurement, testing, and in-service inspections of live-line tools and ensure practices also meet Subpart V performance requirements.

Regarding fall protection for utility work, does Appendix G reference an industry standard I can use? (For example IEEE Std 1307-2004)

Yes — Appendix G lists IEEE Std 1307-2004 (IEEE Standard for Fall Protection for Utility Work), and you can use it as a practical standard for fall protection in utility operations, though using it does not automatically guarantee compliance with Subpart V. The appendix includes IEEE Std 1307-2004 among the referenced documents but clarifies that OSHA will not necessarily consider compliance with the consensus standards as compliance with the subpart. See Appendix G to Subpart V of Part 1926.

  • Apply IEEE 1307-2004 for harnesses, anchorages, rescue planning, and training specifics while confirming you meet Subpart V requirements.

Under Appendix G to Subpart V, are standards for dielectric footwear included and can ASTM F1116-03 and F1117-03 be used for footwear selection?

Yes — Appendix G lists ASTM F1116-03 (Test Method for Dielectric Footwear) and ASTM F1117-03 (Specification for Dielectric Footwear), so you can use them to guide selection and testing of dielectric footwear, but they are guidance rather than an automatic compliance guarantee. Appendix G presents these ASTM standards as helpful detailed specifications employers may follow while also noting OSHA will not necessarily treat compliance with them as meeting Subpart V obligations. See Appendix G to Subpart V of Part 1926.

  • Use the ASTM specs and test methods to choose appropriate dielectric footwear and incorporate their testing intervals into your PPE program in line with Subpart V.

Regarding grounding and protective grounding guides, which IEEE guide is listed in Appendix G that I can consult for protective grounding of power lines?

Appendix G lists IEEE Std 1048-2003 (IEEE Guide for Protective Grounding of Power Lines) as a referenced guide you can consult for protective grounding methods. The appendix names IEEE Std 1048-2003 among the detailed references employers may follow, but it also warns that following consensus standards does not necessarily equal compliance with Subpart V.
