An often-asked question as unhealthy air quality persists in much
of Oregon is whether masks offer any protection. As is often the case, the
answer is: It depends. Masks can create a false sense of security if not properly selected,
fitted and used. Don't expect surgical masks, bandanas, cloth diapers (really,
my dad always had one handy for mowing), or other common masks to protect you
from smoke exposure.
Specialized masks called “respirators” might be of some benefit if
properly selected, fitted, and used. The challenge is that respirators
need to be the right size and worn the right way to be effective, and that is
difficult for many people to do. This means that people who haven’t had help
making sure the respirator fits and that they’re using it right might still be
exposed to smoke -- even if they are wearing it.
Most people will find it difficult to use respirators. They can be
hard to use in a way that actually protects against smoke because:
- First,
you have to find one that is marked with the words “NIOSH” and either
“N95” or “P100” printed on it, to be sure it’s the right kind.
- Selecting
the correct size can be difficult without training.
- The
fit of the respirator must be tested to make sure air does not leak around
the sides. Leaking air means you aren’t protected from smoke.
- Facial
hair often leads to air leaks, making the respirator ineffective.
- Respirators
can be uncomfortable. Even healthy adults may find that the increased
effort required for breathing makes it uncomfortable to wear a respirator
for more than short periods of time. Breathing may be even more difficult
for those with heart and lung conditions.
