Which piece of protective equipment is NOT typically required for engineers?

Uniform pants are generally not classified as protective equipment essential for ensuring safety on the job. While engineers might wear uniform pants as part of their work attire, they do not offer specific protective benefits in terms of safety like the other options do. Helmets, hard hats, and safety glasses are designed to prevent injury from various hazards, such as falling objects, impact, or exposure to harmful materials. These items are integral to maintaining safety standards in the field. While uniform pants may adhere to company dress codes, they do not serve a direct protective purpose, which differentiates them from the equipment that is crucial for operational safety.
