Safety glasses or goggles worn when using the oxyacetylene torch should be what number shaded lens?

  1. No. 3

  2. No. 5

  3. No. 10

  4. No. 8

The correct answer is: No. 3

When using an oxyacetylene torch, safety glasses or goggles should have a No. 3 shaded lens. This shading is necessary to protect the eyes from the intense, bright light produced by the flame. A No. 3 lens provides adequate protection without being too dark, ensuring that the user can see clearly while still preventing potential eye damage. Options B, C, and D do not provide the appropriate level of shading required for safety when using an oxyacetylene torch.
