2 answers:

<span>One observation would be the physical size of Russia compared to other countries, despite a lack of visible borders from space. In addition, part of Russia's outline would likely be obscured by the various clouds and objects in the stratosphere; this would allow the astronaut to view potential cloud and weather patterns on earth. Also, an astronaut could see outlines of Russia's geography such as mountain ranges.</span>

Which type of respirator delivers clean air to the breathing zone from a tank worn by the operator?

MissTica

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%
