An air-purifying respirator that employs a blower to pump air through filters or cartridges and into the user's breathing zone is known as a powered air-purifying respirator, or PAPR. In comparison to a powered or negative-pressure half mask, this generates a positive pressure inside the facepiece or hood, increasing protection.
<h3>What kind of respirator offers a separate source of clean air?</h3>
For entry into or exit from settings regarded as IDLH, Self-Contained Breathing Apparatus (SCBAs) are employed. They can be either open circuit or closed circuit and contain their own breathing air supply.
<h3>What 2 categories of respirators exist?</h3>
Air-purifying and supplied-air respirators are the two main categories of respirators. Respirators that purify the air remove airborne pollutants such particles, dangerous vapors, and/or gases. They are suitable for use in surroundings with low levels of pollution and in areas with enough oxygen.
<h3>When should you use an air purifying respirator?</h3>
a small, unproven area. a lack of oxygen in the atmosphere. Firefighting. Contaminants with a lower explosive limit (LEL—the concentration at which a gas or vapour could ignite) of at least 20%

Answer:
<u>B.It increases the surface area available for ATP production, which results in faster cell growth.</u>
Explanation:
The electron chain reaction in the mitochondria occur at the inner mitochondrial membrane, So greater the folding of inner membrane of mitochondria that is also known as cristea, greater would be ATP Production.
