Question

question 8 1 pts the respirator that would be used in places where dust or solid particles could be inhaled is ____.
○ a mask or mouthpiece with a mechanical filter
○ an air mask
○ a self - contained breathing apparatus
○ a face mask with chemical cartridges

Explanation:

To determine the correct respirator for dust/solid particles:

• A mask with a mechanical filter traps solid particles (dust) as air passes through.
• An air mask (e.g., supplied - air) is for gas/oxygen - limited, not solid particles.
• Self - contained breathing apparatus (SCBA) is for immediate, high - risk environments (e.g., fire), not just dust.
• Chemical cartridges filter gases/vapors, not solid particles.

So the mask with a mechanical filter is correct.

Answer:

A. A mask or mouthpiece with a mechanical filter
