Which physical hazard can be controlled by using welding goggles and barrier screens during welding operations? Group of answer choicesHeatRadonUV RaysX-rays

The physical hazard that can be controlled by using welding goggles and barrier screens during welding operations is UV Rays.

Step 1: Understand the question - The question is asking which physical hazard can be controlled or minimized by using specific safety equipment (welding goggles and barrier screens) during welding operations.

Step 2: Analyze the answer choices - The options given are Heat, Radon, UV Rays, and X-rays.

Step 3: Eliminate incorrect options - Heat is a hazard in welding, but it is not specifically controlled by goggles and screens. Radon is a radioactive gas and not directly related to welding. X-rays are a form of radiation that is not typically a hazard in standard welding operations.

Step 4: Select the correct answer - UV Rays are a known hazard in welding operations. The intense light produced by welding can cause a "welder's flash" or photokeratitis, a painful condition that can result in temporary or permanent vision loss. Welding goggles and barrier screens are specifically designed to protect against this hazard. Therefore, the correct answer is UV Rays.
