Removing PPA properly is important so dust is not
spread.
NOTES FOR SLIDE 48
As you review the information in
the slide on how to remove the
PPA, demonstrate each step by
removing the PPA worn by you or
your volunteer. Make sure you
have a trash can or bag to put the
discarded PPA into.
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:
NOTES FOR SLIDE 49 and 50
Before starting the class, you will
need to make copies of the steps
on the next page and cut out each
individual step. Make enough
copies so each of small group
has a complete set of steps.
Recommend you place each
group of steps into an envelope
or clip together with a paper clip.
Divide the participants into 3 or 4
groups.
Explain to the class they are going to
work on an exercise to see if they
can put in order the correct steps for
entering and exiting an anteroom.
Read the scenario on the slide. Check to make sure everyone understands the
scenario.
43
Distribute a set of steps to each group. Tell them they can begin. Walk around
and answer any questions.
Once all the groups have completed the exercise, advance the PowerPoint and
show the class the correct order. Have each group correct any errors.
Collect the sets of individual steps for use in future classes.
Hand washing and proper cleaning of clothing are
important.
NOTES FOR SLIDE 51
Germs are very common in hospitals.
Germs from unwashed hands can be
transferred to other objects, like
handrails, table tops, materials or
tools, and then transferred to another
person’s hands.
People frequently touch their eyes, nose, and mouth without even realizing it.
Germs can get into the body through the eyes, nose and mouth and make us
sick.
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
before leaving the work area. If your job requires you to perform work activities
outside before entering the health-care facility, you should vacuum your clothes
before entering the facility.
44
Realized you forgot your reading
glasses!
Enter the anteroom and close the
door.
Vacuum clothing with HEPA
vacuum.
Put on PPA, including shoe covers.
Exit the anteroom and close the
door.
Retrieve reading glasses.
Re-enter the anteroom and close
the door.
Remove PPA and shoe covers.
Open the door to the work area,
enter the area and close the door.
45
Controlling the air pressure can prevent the spread of
dust.
NOTES FOR SLIDE 52
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
balancing the ventilation system so
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
occupied areas into the work area.
A HEPA negative air machine is used to pull air from the
work area.
NOTES FOR SLIDE 53
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
can remove at least 99.97% of airborne particles 0.3 microns in diameter.
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
meter and one-thousandth of a millimeter. It is a shorten word for micrometer. To
