What signals are used for "lift" and "lower"?

• A. 'Lift' is indicated by raising one arm
• B. 'Lift' is indicated by a waving motion
• C. 'Lower' is indicated by two arms raised above the head
• D. 'Lower' is indicated by crossing arms in front

Answer: (A)

The signal for "lift" is indeed communicated by raising one arm, which is a clear and universally recognized gesture among signal personnel. This motion effectively indicates to the operator that the load should be lifted. The simplicity of this signal ensures that it can be easily seen and understood from a distance, which is crucial for safety and effective communication on a job site where noise and other distractions may be present. The other choices may lead to confusion; for instance, a waving motion may not be as easily interpreted in high-activity environments, and using two arms above the head or crossing arms could also create ambiguity and may not align with standard signaling practices recognized in the industry. By utilizing the straightforward approach of raising one arm for "lift", it maintains clarity and enhances the safety communications between the signal person and the equipment operator.
