Answer:

To solve these matching questions, we analyze each term and its definition:

1.

A protective screen around a welding operation (shielding) → Shielding (matches "A protective screen set up around a welding operation...").

2.

Process using heat to join metal (brazing involves heat for joining) → Brazing (matches "A process using heat...to join pipe").

3.

Filters for small particles (High - efficiency particulate air (HEPA) filters) → High efficiency particulate air (HEPA) filters (matches "Filters designed to capture very small particles").

4.

Structure to protect workers (toeboard on scaffolds) → Toeboard (matches "A structure...to prevent cave - ins...on scaffolds").

5.

Working near hazard without contact (proximity work) → Proximity work (matches "Working near a hazard, but not actually in contact").

6.

Vertical barrier on scaffolds (welding curtain? No, welding curtain is for welding. Wait, "vertical barrier to prevent materials from falling" → Welding curtain? No, correct is "Toeboard"? Wait, re - check: "A vertical barrier called a(n) _ is used at lip on scaffolds..." → actually, the correct term for a vertical barrier on scaffolds to prevent falls is Toeboard? Wait, no, the options: Toeboard is a horizontal? Wait, the options given: Shrouded, Wind sock, HEPA, Welding curtain, Toeboard, Proximity work, Brazing. Wait, "vertical barrier" for scaffold fall protection: Welding curtain is not, Toeboard is a horizontal strip. Wait, maybe "Welding curtain" is wrong. Wait, the question: "A vertical barrier called a(n) _ is used at lip on scaffolds to prevent materials from falling." The correct term here (from options) is Welding curtain? No, maybe I made a mistake. Wait, let's re - match:

• 1. Shielding: protective screen around welding.
• 2. Brazing: heat - based metal joining.
• 3. HEPA filters: capture small particles.
• 4. Toeboard: protect workers in trench (prevents cave - ins? No, toeboard on scaffolds prevents falls). Wait, the question says "in trench lacks the ability to prevent cave - ins" → no, maybe "Toeboard" is for scaffolds. Wait, the options:

Let's list the answers properly:

1. Shielding (protective screen for welding).
2. Brazing (heat - based metal joining).
3. High efficiency particulate air (HEPA) filters (captures small particles).
4. Toeboard (structure for worker protection, prevents falls from scaffolds).
5. Proximity work (working near hazard without contact).
6. Welding curtain? No, wait, "vertical barrier on scaffolds" → maybe "Welding curtain" is incorrect. Wait, the options: the vertical barrier to prevent materials from falling on scaffolds is a Toeboard? No, toeboard is horizontal. Wait, maybe the answer is Welding curtain is wrong. Wait, let's check the options again. The options for the blanks (from the image) are: Shrouded, Wind sock, High efficiency particulate air (HEPA) filters, Welding curtain, Toeboard, Proximity work, Brazing.

So:

1. A protective screen around welding → Shielding (wait, the option is "Shrouded"? No, the first option is "Shrouded"? Wait, the left - hand list (answers) is: Shrouded, Wind sock, High efficiency particulate air (HEPA) filters, Welding curtain, Toeboard, Proximity work, Brazing.

So:

1. Protective screen around welding operation → Shrouded? No, "Shielding" is not an option. Wait, the option is "Shrouded"? Maybe the correct answer for 1 is Shrouded (protective screen).

1. Process with heat to join metal → Brazing.

1. Filters for small particles → High efficiency particulate air (HEPA) filters.

1. Structure to protect workers (trench) → Toeboard (toeboard in trenches? No, toeboard on scaffolds. Wait, maybe "Welding curtain" is wrong. Wait, the question 4: "A structure that is used to protect workers in trench lacks the ability to prevent cave - ins is ___." The correct term for a trench protection that can't prevent cave - ins is a Toeboard? No, maybe "Proximity work" is wrong. Wait, I think I need to re - align:

Let's do each question:

1. Protective screen around welding → Shrouded (matches "protective screen").

1. Heat - based metal joining → Brazing (matches "using heat...to join pipe").

1. Small particle filters → High efficiency particulate air (HEPA) filters (matches "capture very small particles").

1. Trench protection (can’t prevent cave - ins) → Toeboard (toeboard in trenches? Maybe, as a structure for protection).

1. Working near hazard (no contact) → Proximity work (matches "Working near a hazard, but not actually in contact").

1. Vertical barrier on scaffolds → Welding curtain? No, "Welding curtain" is for welding. Wait, "vertical barrier to prevent materials from falling" → Welding curtain is not, but from options, the only vertical barrier - like option is Welding curtain? No, maybe "Toeboard" is horizontal. Wait, maybe the answer is Welding curtain is wrong, and it's Toeboard? No, I'm confused. Wait, the 7th question: "A(n) ___ shows which way the wind is blowing" → Wind sock (matches "shows wind direction").

So correcting:

1. Wind sock (shows wind direction).

Now, re - listing all answers:

1. Shrouded (protective screen around welding).
2. Brazing (heat - based metal joining).
3. High efficiency particulate air (HEPA) filters (captures small particles).
4. Toeboard (trench protection).
5. Proximity work (working near hazard).
6. Welding curtain (vertical barrier on scaffolds? Maybe, as a barrier).
7. Wind sock (shows wind direction).

Final Answers (matching each blank):

1. Shrouded
2. Brazing
3. High efficiency particulate air (HEPA) filters
4. Toeboard
5. Proximity work
6. Welding curtain
7. Wind sock
