What clothing is recommended for a signal person to increase visibility?

High-visibility clothing is recommended for a signal person because it significantly enhances their ability to be seen in various work environments, especially those involving heavy machinery and vehicles. Wearing bright colors, such as fluorescent yellow or orange, along with reflective materials, allows a signal person to stand out against the backdrop of the job site, which may include equipment, vehicles, or other personnel. This visibility is crucial for safety, as it helps operators and other workers easily identify the signal person from a distance, reducing the likelihood of accidents or miscommunication.

In contrast, dark attire and regular work uniforms may blend into the environment, making it difficult for operators to spot the person providing signals. Camo gear, while suitable for concealment in certain contexts, does not serve the purpose of visibility on a construction site and can actually hinder safety by making the wearer less noticeable. Therefore, high-visibility clothing is the best choice for ensuring the signal person's presence is clearly communicated to everyone on site.
