Appendix A to §1910.269 - Flow Charts
This appendix presents information, in the form of flow charts, that illustrates the scope and application of § 1910.269. This appendix addresses the interface between § 1910.269 and Subpart S of this Part (Electrical), between § 1910.269 and § 1910.146 (Permit-required confined spaces), and between § 1910.269 and § 1910.147 (The control of hazardous energy (lockout/tagout)). These flow charts provide guidance for employers trying to implement the requirements of § 1910.269 in combination with other General Industry Standards contained in Part 1910. Employers should always consult the relevant standards, in conjunction with this appendix, to ensure compliance with all applicable requirements.
Appendix A-1 to §1910.269 - Application of §1910.269 and Subpart S of this Part to Electrical Installations.
1 This chart applies to electrical installation design requirements only. See Appendix A-2 for electrical safety-related work practices. Supplementary electric generating equipment that is used to supply a workplace for emergency, standby, or similar purposes only is not considered an electric power generation installation.
Appendix A-2 to §1910.269 - Application of § 1910.269 and Subpart S of this Part to Electrical Safety-Related Work Practices1.
1 This flowchart applies only to the electrical safety-related work practice and training requirements in §1910.269 and §§ 1910.332 through 1910.335.
2 See §§1910.269(a)(1)(ii)(B) and 1910.331(b) and (c)(1).
3 This means commingled to the extent that the electric power generation, transmission, or distribution installation poses the greater hazard.

1 If the electrical installation meets the requirements of §§ 1910.302 through 1910.308 of this part, then the electrical installation and any associated electrical safety-related work practices conforming to §§ 1910.332 through 1910.335 of this part are considered to comply with these provisions of § 1910.269 of this part.
2 These provisions include electrical safety and other requirements that must be met regardless of compliance with subpart S of this part.
Appendix A-3-Application of §1910.269 and Subpart S of this Part to Tree Trimming
1 3.05 meters (10 feet) plus 0.1 meters (4 inches) for every 10 kilovolts over 50 kilovolts.
Appendix A-4 to §1910.269 - Application of §§1910.147, 1910.269 and 1910.333 to Hazardous Energy Control Procedures (Lockout/Tagout).
1 If a generation, transmission, or distribution installation conforms to §§ 1910.302 through 1910.308, the lockout and tagging procedures of § 1910.333(b) may be followed for electric-shock hazards.
2 This means commingled to the extent that the electric power generation, transmission, or distribution installation poses the greater hazard.
3 Paragraphs (b)(2)(iii)(D) and (b)(2)(iv)(B) of §1910.333 still apply.
4 Paragraph (b) of §1910.333 applies to any electrical hazards from work on, near, or with electric conductors and equipment.
Appendix A-5 to §1910.269 - Application of §§1910.146 and 1910.269 to Permit-Required Confined Spaces.
1 See § 1910.146(c) for general nonentry requirements that apply to all confined spaces.
Note: Paragraph (t) of §1910.269 contains additional requirements for work in manholes and underground vaults.
