AWS Welding Inspection and Testing Certification Practice Test

Is it necessary to use shaded lenses when oxy-fuel cutting due to low ultraviolet light?

1. Yes, it is necessary to use shaded lenses.

2. No, it is not necessary to use shaded lenses.

3. Shaded lenses are only needed for certain types of gas.

4. Only specialized lenses should be used.

The correct answer is: No, it is not necessary to use shaded lenses.

When performing oxy-fuel cutting, the intensity of ultraviolet light produced is not high enough to pose significant risks to the eyes, making specialized shaded lenses unnecessary in this context. Oxy-fuel cutting does generate some ultraviolet light, but it is considerably less intense than what is produced during processes like arc welding. Standard safety practice during oxy-fuel cutting includes protective eyewear, but shaded lenses specifically designed for welding are typically reserved for processes that involve higher levels of UV radiation. In environments where only minimal UV exposure occurs, clear safety glasses are often sufficient. Proper eye protection practices emphasize the need for various levels of protection based on the specific hazards of each task. Thus, while safety eyewear is essential in any welding or cutting scenario, the use of shaded lenses specifically for oxy-fuel cutting is not deemed necessary.
