The statement regarding Appendix A to OSHA 29 CFR 1910.147 being optional and may be followed at the employer's discretion is correct because this appendix provides guidance on lockout/tagout procedures, which are crucial for ensuring safety in the workplace during maintenance or repair of machinery and equipment. While the regulation itself sets forth mandatory safety standards, Appendix A serves to clarify and illustrate these standards, giving employers the flexibility to implement practices as deemed appropriate for their specific workplace environment. This allows for a tailored approach to compliance while encouraging the adoption of best practices for safety.

Other options are incorrect as they misinterpret the nature of Appendix A. For instance, stating it is a mandatory guideline would imply that all elements within it must be followed, which is not the case; rather, it serves as a framework that can be adapted. Additionally, claiming it pertains solely to industrial settings overlooks its broader applicability across various sectors where lockout/tagout procedures might be necessary. Lastly, describing it as merely an example rather than a regulation diminishes its importance in providing context and clarity for compliance with the main regulation.
