Which guidelines outline hoisting signals?

The guidelines that outline hoisting signals are found in the ANSI/ASME B30.5 hoist standard. This standard specifically addresses the safety requirements for construction hoisting equipment, including guidelines on signal communication between the operator and ground personnel. It includes detailed descriptions of the various hand signals and voice commands that should be used for safe operation, ensuring clarity and safety throughout the hoisting process.

While OSHA Safety Code also contains regulations regarding safety and operational procedures in the workplace, it does not provide detailed guidelines specifically for hoisting signals as found in the ANSI/ASME B30.5 standard. The National Electrical Code primarily focuses on electrical installations and safety, and the Institute of Electrical and Electronics Engineers Standards encompasses a broader range of electrical and electronic engineering guidelines rather than directly addressing hoisting operations. Thus, the ANSI/ASME B30.5 hoist standard is the most relevant and specific source for hoisting signals.
