Answer :
Final answer:
Under a welding helmet, for tasks other than welding, the recommended protective eyewear to safeguard the eyes from potential hazards like sparks and UV rays are safety glasses. These glasses are specially designed to provide fuller coverage and are made from materials that offer superior protection against UV radiation. So, the correct option is D.
Explanation:
The question pertains to the recommended protective eyewear to be worn underneath a welding helmet for eye safety during tasks other than welding. When engaging in welding activities, it's crucial to understand the hazards involved, particularly the risk posed by the intense light and thermal energy generated by welding processes.
This thermal energy not only melts metal but can also emit harmful ultraviolet radiation that can cause serious damage to the retina if the eyes are not adequately protected. Considering this, the recommended protective eyewear under a welding helmet is safety glasses. These are designed to provide protection from the sides and are made of materials that can absorb or block harmful ultraviolet radiation more effectively than ordinary glasses or sunglasses.
Unlike sunglasses or non-safety-rated glasses, safety glasses are specifically designed to withstand impacts and provide fuller coverage, ensuring that the eyes are shielded from flying debris, sparks, and harmful radiation. Also, many safety glasses are made from polycarbonate materials known for their superior protection against UV rays. Hence, for tasks other than welding but where the eyes still need protection, especially when wearing a welding helmet, safety glasses are the most appropriate choice.
