Which category relies on protective devices like respirators and hearing protection to reduce exposure?

• A. Engineering Controls
• B. Administrative Controls
• C. Personal Protective Equipment
• D. Welding Controls

Answer: (C)

Personal Protective Equipment is the category that relies on protective devices worn by the worker to reduce exposure. Respirators and hearing protection are classic examples of PPE: they don’t change the work environment or the way work is performed, but instead create a barrier or filter for the worker’s body to lower the amount of hazard reaching them. In welding, this matters because fumes, gases, and high noise levels can be mitigated by using respirators when ventilation isn’t enough and by wearing hearing protection to prevent hearing loss. While engineering controls (like ventilation) and administrative controls (like work practices or schedules) aim to reduce exposure at the source or through procedures, PPE provides a direct, personal layer of protection worn by the worker.
