Which safety measure best reduces UV/IR exposure and includes multiple controls?

• A. Reducing power only
• B. Time, distance, shielding, and short exposure durations
• C. PPE only
• D. Administrative controls only

Answer: (B)

Layered protection is the most reliable way to reduce UV/IR exposure. Exposure to UV/IR can harm skin and eyes, so combining several controls creates a stronger defense than any single measure. Limiting how long you’re exposed reduces the dose you receive; increasing distance from the source lowers the intensity that reaches you; shielding provides a physical barrier to attenuate or block the radiation; and keeping work to short exposure periods reinforces those limits through work practices. Together these controls form a multi-faceted approach that work even if one control isn’t perfect. Relying on power reduction alone, PPE only, or administrative controls by themselves isn’t as robust as using time, distance, shielding, and shortened exposure durations in combination.
