The illustration shows a generic example of a box plot with the maximum, third quartile, median, first quartile, and minimum values labeled. The relative vertical spacing between the labels reflects the values of the variable in proportion.
Respirator Types Two basic types of respirators are: â¢ air-purifying; andâ¢ supplied-air respirators. Air-purifying respirators remove airborne contaminants such as particles, toxic vapors, and/or gases.
Non-alcohol wipe pads can be used to supplement cleaning during intermittent use. Storing Respirators: Clean respirators should be stored in nonporous, sturdy, airtight containers (like a Ziploc plastic bag). To avoid collecting dust, the respirator should be put away as soon as it is dry. Respirator face pieces and valves should be stored in a manner that does not distort the shape.
