1
A disposable mask is the simplest type of atmosphere-supplying respirator.
2
A mask that filters out 95% of the particles in the air will be marked with an "N95" efficiency code.
3
An estimated 5 million workers in the U.S. wear respirators while they are doing their job.
4
A particulate respirator will become increasingly difficult to breathe through as its filter fills up with trapped contaminants.
5
A "half mask" respirator covers your face from your hairline to below your chin.
6
Chemical filters called "sorbents" are used by particulate respirators to protect you from airborne contaminants.
7
Using the wrong filter in a respirator can be just as dangerous as not wearing any respirator at all.
8
"Tight-fitting" respirators depend on an airtight seal against your face to prevent airborne contaminants from leaking inside where you can breathe them.
9
A filter's "service life" is the length of time that it can protect you against airborne contaminants.
10
Wearing a respirator on the job does not place any particular physical demands on the people who use them.
