Preventing dust minimizes patient exposures.
NOTES FOR SLIDE 39
Only show the title of the
PowerPoint slide
“
Preventing dust
minimizes patient exposures
.”
and the first 2 bullets. Discuss the
information with the class.
Explain to the class how the way they
work can also impact how much dust is
generated.
Before advancing the slide,
ASK THE CLASS:
What are some examples of engineering controls or work practice modifications
they can do to limit the amount of dust that is generated?
Write the participant responses on a whiteboard or flipchart.
Advance the slide and compare the list generated by the participants with
the examples listed on the slide. Emphasize and discuss the information in
the last bullet.
The primary function of a barrier is to control the air
quality in occupied areas.
NOTES FOR SLIDE 40
The ultimate goal for erecting
barriers is to prevent the spread of
construction dust into the hospital by
creating an airtight seal within the
work area. Small, short duration
projects generating minimal dust
may use a mobile containment cube
or soft wall system to prevent dust
from escaping the work area. Any project that produces moderate to high levels
of dust may require a hard wall, dust-proof system
Fire control is important on all jobsites but in healthcare, it’s critical. Many
hospital patients cannot be evacuated if there is an emergency due to the nature
of their illness, dependency on life saving equipment and other medical reasons.
37
Maintain fire prevention measures such as firewalls is an important consideration
when selecting the appropriate barrier.
Mobile containment cubes are used for inspection and
short-term cavity work.
NOTES FOR SLIDE 41
Before starting this section, bring
the unassembled mobile
containment cube into the
classroom or hands-on training
area.
Accessing the space above ceilings
or behind walls during construction,
renovation or maintenance projects can release dust, mold spores and other
contaminants into the air. A mobile containment cube is engineered to help
contain the spread of these airborne particles into other areas of the facility. Ideal
for multiple, quick-entry jobs or longer-term construction projects, a mobile
containment cube rolls quickly into position and extends securely against the
ceiling to help minimize exposure to building occupants and contamination of
products or sensitive equipment.
WARNING: Watch out for sprinkler heads in the ceiling when erecting/moving the
mobile containment cube.
After providing a brief introduction to mobile containment cubes, show the
mobile containment cube assembly video by clicking on the hyperlink
attached to the picture.
After the video is done, demonstrate how to set up the containment. Leave
the containment cube up if possible. You will use it to show the negative air
set up later in the class.
38
To enclose a larger work area a soft wall barrier system
can be used.
NOTES FOR SLIDE 42
Before starting this section, bring
the ZipWall® kit into the
classroom or hands-on training
area. If there is room in the
classroom, assemble a small
section of the ZipWall® for the
class to see.
The walls are erected from the floor to the ceiling or from the floor to the deck.
Tape is used to secure the plastic to the ceiling, walls, and floor. Soft wall
systems can also use sill seals and metal tracks to help seal the plastic sheeting.
After providing a brief introduction to soft wall barriers, show the class the
various components that are used to construct a barrier.
Explain to the class the ICRA Awareness class does not teach them how to
set up soft wall barriers. This training is done in the longer ICRA Worker
course.
An entry must be created to access the work area.
NOTES FOR SLIDE 43
The type of entry used will depend
on the needs of the project. The
most common doorway used in a
soft wall barrier is the zipper door.
The flap-door or T-door is commonly
used in the asbestos abatement
industry and maybe found on an
ICRA hospital jobsite.
It’s important to remember to close all doors, including zipper doors after entering
or exiting the work site. If you find an open door close it immediately. Leaving it
open can affect the negative air pressure in the work area.
