Which statement about infrared hazard with fiber optics is accurate?

Infrared radiation used in fiber-optic systems is invisible to the eye, yet it can be dangerous to the retina if exposure occurs. Because IR light is not visible, you might not realize you’re looking at a beam, but the energy can still be focused onto the retina and cause burns or permanent damage. For safety, avoid looking directly into any fiber end or beam, use eye protection appropriate for the IR wavelength in use, and keep beams enclosed or terminated safely. The other statements don’t fit because IR is not visible, can still harm the eye, and looking into a fiber end can be hazardous.
