What type of personal protective equipment (PPE) is recommended for signal persons?

The recommended personal protective equipment (PPE) for signal persons includes hard hats, high-visibility vests, and steel-toed boots because these items are crucial for ensuring safety in a construction or industrial environment.

Hard hats protect against head injuries from falling objects, which is particularly important for signal persons who often work in areas with heavy machinery and potential overhead hazards. High-visibility vests are essential for making signal persons easily seen by operators and other workers, which is critical for preventing accidents and ensuring effective communication. Steel-toed boots offer protection against foot injuries from heavy equipment and materials that may be dropped or rolled over, providing the necessary support and safety for signal persons who are often on their feet and in potentially hazardous locations.

In contrast, while gloves and goggles, respirators and ear protection, and face shields and knee pads provide important safety measures in certain contexts, they are not specifically tailored to the needs of signal persons and the unique hazards they face. The combination of hard hats, high-visibility vests, and steel-toed boots makes option two the most appropriate choice for the role of a signal person.
