2. filters designed to capture very small particles are as ______.
3. a structure that is used to protect workers in trenc (likely trench typo) lacks the ability to prevent cave - ins is ______.
4. working near a hazard, but not actually in contact with it is known as ______.

dropdown at the end: proximity work

Explanation:

Question 1

A protective screen around a welding operation to safeguard workers is a welding curtain (matches the description of shielding? Wait, no—wait, the dropdown has "Welding curtain"? Wait, the options: the first dropdown options (from the image: Shielding, Toeboard, High efficiency particulate arrestance (HEPA) filters, Brazing, Wind sock, Proximity work, Welding curtain). Wait, a protective screen for welding workers is a Welding curtain? Wait, no—shielding? Wait, no, let's recheck. The question: "A protective screen set up around a welding operation designed to safeguard workers not directly involve operation is a(n) ______." The correct term here is "Welding curtain"? Wait, no, maybe "Shielding"? Wait, no, the options: looking at the dropdown, one of them is "Welding curtain"? Wait, the user's image shows the dropdown list as: Shielding, Toeboard, High efficiency particulate arrestance (HEPA) filters, Brazing, Wind sock, Proximity work, Welding curtain. Wait, a welding curtain is a protective screen for welding. So the answer is Welding curtain? Wait, no, maybe "Shielding"? Wait, no, let's think again. The correct term for a protective screen around welding to protect others is a welding curtain? Or shielding? Wait, maybe I made a mistake. Wait, the options: the first question's answer is "Welding curtain"? No, wait, the options are: Shielding, Toeboard, HEPA filters, Brazing, Wind sock, Proximity work, Welding curtain. Wait, "Welding curtain" is a type of shielding? No, the question is about a protective screen. So the correct answer is Welding curtain? Wait, no, maybe "Shielding" is broader, but the option has "Welding curtain" as a specific type. Wait, the user's image: the first blank is to be filled with one of the dropdown options. Let's check each:

1. Protective screen around welding: Welding curtain (since it's a curtain used for welding protection). So answer is Welding curtain.

Question 2

A process using heat over 800°F (427°C) with filler metal to join pipe is brazing (brazing uses heat above 800°F, unlike soldering which is below). So the answer is Brazing.

Question 3

Filters capturing very small particles: High efficiency particulate arrestance (HEPA) filters (HEPA filters are designed for capturing tiny particles). So answer is High efficiency particulate arrestance (HEPA) filters.

Question 4

Answer:

s:

1. Welding curtain
2. Brazing
3. High efficiency particulate arrestance (HEPA) filters
4. Toeboard
5. Proximity work
