Final answer:
Clear safety goggles are not suitable for eye protection from welding radiation because they lack the necessary filtration to block harmful light and UV radiation. Proper protection like welding helmets and goggles with filter plates is essential.
Step-by-step explanation:
The protective equipment not suitable for eye protection from welding radiation includes clear safety goggles. Welding helmets with filter plates, safety goggles with filter plates, and protective screens are all designed to protect the eyes from the intense light and UV radiation produced by welding. Clear safety goggles, while providing some protection against impact, do not have the necessary filtration to block the harmful radiation produced during welding, which can lead to conditions like welder's flash or cataracts. Proper eye protection is vital when welding as the thermal energy produced can be felt on exposed skin from a few meters away, and its light can be seen for kilometers.
