Which statement describes UV exposure controls in practice?

• A. They rely only on PPE
• B. They include time, distance, and shielding
• C. They cannot be implemented indoors
• D. They are unnecessary for UV hazards

Answer: (B)

Controlling UV exposure relies on reducing the dose before it reaches a worker by combining time management, distance, and shielding. Increasing distance from a UV source dramatically lowers the intensity, since UV energy diminishes with separation. Limiting how long you’re near the source directly reduces the total exposure. Shielding provides a physical barrier that blocks or attenuates UV radiation from reaching the eyes and skin. These approaches are engineering and administrative controls that work together with PPE, which serves as an additional safety layer but should not be the only defense. Indoors, you can implement these controls by enclosing the UV source, using interlocks and barriers, and restricting access with warnings and procedures. So, relying only on PPE, claiming indoor controls aren’t possible, or saying controls aren’t needed misses the practical, effective way to manage UV hazards.
