Which of the following is an example of proper protective equipment?

The correct choice of safety glasses, goggles, and a welding helmet exemplifies proper protective equipment because these items are specifically designed to protect the user from various hazards encountered in many work environments, especially in construction and welding operations.

Safety glasses and goggles shield the eyes from debris, chemicals, and sparks, which are prevalent risks in many job sites. A welding helmet is essential for protecting the face and eyes from the intense light produced during welding, as well as from burns and flying particles. Collectively, these items form a comprehensive approach to eye and face protection, adhering to safety regulations and industry standards.

In contrast, the other options do not provide the necessary level of protection required for hazardous work conditions. Sneakers and a baseball cap lack the supportive structure, traction, and protection from falling or sharp objects that specialized work footwear and headgear offer. Regular glasses may not provide the impact resistance or side protection of safety glasses, and a scarf does not serve as appropriate head and face protection in environments where fumes, sparks, or other dangers are present. Work boots alone lack sufficient protection for the eyes and face, which are critical in many job scenarios.
