Question

question 7 of 10
which of the following are the three types of air - supplying respirators?
select all that apply

• supplied - air respirators (sars)
• powered air - purifying respirator (papr)
• self - contained breathing apparatus (scba)
• combination respirators, a combination of scba and sar

Explanation:

To determine the three types of air - supplying respirators, we analyze each option:

• Supplied - air respirators (SARs): These are a type of air - supplying respirator as they receive air from an external source.
• Powered air - purifying respirator (PAPR): PAPRs are air - purifying respirators, not air - supplying respirators. They work by purifying the ambient air.
• Self - contained breathing apparatus (SCBA): SCBAs are air - supplying respirators as they have their own air supply.
• Combination respirators, a combination of SCBA and SAR: These are also a type of air - supplying respirator as they combine two air - supplying technologies.

So the three types of air - supplying respirators are Supplied - air respirators (SARs), Self - contained breathing apparatus (SCBA), and Combination respirators (a combination of SCBA and SAR).

Answer:

A. Supplied - air respirators (SARs)
C. Self - contained breathing apparatus (SCBA)
D. Combination respirators, a combination of SCBA and SAR
