When is it necessary to have a dedicated signal person on site?

Having a dedicated signal person on site is essential when visibility or site conditions make communication difficult. In scenarios where environmental factors such as poor visibility due to weather, obstacles that obscure sight lines, or other distractions may impede effective communication between the crane operator and ground personnel, a signal person plays a critical role. This individual focuses on ensuring that the crane moves safely and efficiently by conveying clear signals that the operator relies on to perform lifts correctly.

Effective communication is crucial in rigging and hoisting operations; without it, there is a significant risk of accidents. The signal person's presence becomes indispensable to mitigate these risks when conditions may not allow for optimal communication between the operator and the team on the ground. In contrast, experienced workers or light loads do not necessarily require additional signaling measures to enhance safety when conditions are favorable. Similarly, while the operator's experience can impact safety, challenges with visibility or site conditions remain a priority concern warranting a dedicated signal person.
