Removing PPA properly is important so dust is not
Once all of the PPA is removed, place it in the appropriate trash can or bag.
Some work areas may be too small to accommodate a trash can and workers will
need to bring a trash bag with them to dispose of their PPA.
Typical procedure to follow when entering and exiting
through an anteroom:

Germs are very common in hospitals.
Germs from unwashed hands can be
handrails, table tops, materials or
tools, and then transferred to another
People frequently touch their eyes, nose, and mouth without even realizing it.
Handwashing can prevent about 30% of diarrhea-related sicknesses and about
20% of respiratory infections (e.g., colds) according to the Centers for Disease
Control and Prevention (CDC).
To remove dust from your clothes, vacuum yourself with a HEPA filtered vacuum

Controlling the air pressure can prevent the spread of
When the air pressure within the
work area is less than the air
pressure outside the work area,
negative air pressure occurs.
Negative pressure is created by
that more air is mechanically
exhausted from a room than is mechanically supplied. This creates a ventilation
imbalance, which the room ventilation makes up by continually drawing in air
from outside the room.
To make up for this loss of air, clean air is pulled from the public or patient
A negative air machine uses ducting
to remove contaminated air from a
sealed containment area. The
filtered air is exhausted outside of
the containment. This creates
negative air pressure (a slight
vacuum effect) inside the
containment relative to surrounding
areas. A negative air machine application helps limit the spread of contaminants
to other areas inside the structure.
A HEPA filter is a type of high efficiency particulate air filter. This type of air filter
Particles of this size are the most difficult to filter and thus the most penetrating
particle size. Particles that are larger or smaller are filtered with even higher
efficiency. HEPA filters are the most effective air filtration filters to remove
contaminants from the air.
A micron is a unit of measure in the metric system. It equals one-millionth of a
