Explanation:

Question 1:

A protective screen around welding to safeguard workers (not direct) is a welding curtain. Welding curtains shield from sparks/UV without being in direct line. Shielding is broader, toe - board is for trenches, wind sock for air, HEPA for particles, proximity work is different.

Welding (joining metals with heat > 800°F and filler) is the process. Shielding is protection, toe - board for trenches, wind sock for air, HEPA for filtration, proximity work is not joining.

HEPA filters capture very small particles (like in welding fumes). Shielding is physical, toe - board for trenches, wind sock for air, welding curtain for light/sparks, proximity work is not filtration.

Answer:

Welding curtain
