Answer 2

Electromagnetic energy given off by an arc or flame can injure workers’ eyes and is commonly referred to as radiant energy or light radiation. For protection from radiant energy, workers must use personal protective equipment, such as safety glasses, goggles, welding helmets, or welding face shields. This equipment must have filter lenses with a shade number that provides the appropriate level of protection. A shade number indicates the intensity of light radiation that is allowed to pass through a filter lens to one’s eyes. Therefore, the higher the shade number, the darker the filter and the less light radiation that will pass through the lens.
