Which shade number might be used for heavy cutting, over 6 inches, among the options 4,5,6,7?

• A. 4
• B. 5
• C. 6
• D. 7

Answer: (B)

Shade numbers reflect how much protection your eyes need from radiant energy during cutting. The goal is to use the lowest shade that still provides adequate protection so you can see well enough to work safely. For heavy cutting, especially when the cut is over 6 inches, the standard in this item targets a mid-range level that protects you without overly darkening your view. That’s why shade five is the best choice here: it gives enough protection for the intensity of heavy cutting while keeping visibility clear enough to perform the task accurately. Shades four would be too light for this level of exposure, while six or seven would unnecessarily reduce visibility. Always follow the specific safety standard used for your job.
