Where would you find OSHA's standard method hand signals?

The correct answer is found in OSHA 1926.1400 Appendix A, which specifically provides the standard hand signals for crane operations. These signals are crucial for ensuring safe communication between the crane operator and the ground crew during lifting operations. The appendix outlines various hand signals that can be universally understood, enhancing safety and reducing the risk of accidents on job sites.

In contrast, the other options reference different standards or sections that do not specifically contain the OSHA-approved hand signals. OSHA 1926.1430 Schedule B pertains to other requirements regarding cranes but not specifically to hand signals. ASME B30.5 Section 3 focuses more on the general requirements for mobile crane operations but isn't dedicated to hand signals as described in OSHA standards. ANSI Z535 Standard Table deals with safety signage and colors but does not provide the specific crane hand signals laid out in OSHA guidelines. Therefore, the OSHA 1926.1400 Appendix A is the correct and relevant source for standard method hand signals used in crane operations.
