| Cleaning
up plaster, drywall and stucco debris originating from minor damage
in various Mt. A. campus buildings. |
| 1. |
Use
barricade tape to restrict access to area of damage. Tracking dust
and debris about via foot traffic is the greatest concern. Overall,
drywall dust, stucco and plaster are not inherently dusty and exposure
to students and university staff resulting from the actual damage
is expected to be negligible. |
| 2. |
Don
respirators and, if contact with debris is likely, disposable suits
over street clothes. |
| 3. |
Mist
area of damage and fallen debris with soapy water. |
| 4. |
Place
larger materials directly into waste bag trying to avoid dust generation
as possible. |
| 5. |
Use
HEPA vacuum to remove remaining dust |
| 6. |
Repair
damaged area as required. Cover floor with polyethylene sheeting as
needed to contain expected dust generation. Additional removal of
asbestos containing materials should be avoided but removal of some
materials will be required to facilitate repairs. |
| 7. |
Use
6-mil or rip-proof tarp to cover damaged area if proper repair will
require additional asbestos removal that will be contracted out. Otherwise,
repair area as required by crackfilling or covering with rigid materials
such as plywood or sheetrock. |
| 8. |
Reclean
areas as per items 3-5 above. |
| 9. |
Fold
polyethylene floor covering toward centre and dispose of as asbestos
waste together with disposable suits and other debris. Place waste
bag inside second bag and seal. |
| |
|
| Minor
work to plaster and drywall walls and ceilings to install pictures,
shelves, hangers and electrical boxes. |
| 1. |
Use
barricade tape to restrict access to work area. Tracking dust and
debris about via foot traffic is the greatest concern. Overall, drywall
dust, stucco and plaster are not inherently dusty and exposure to
students and university staff resulting from the actual work is expected
to be negligible. |
| 2. |
Don
respirators and, if contact with debris is likely, disposable suits
over street clothes. |
| 3. |
Mist
work area with soapy water. |
| 4. |
Cover
area beneath work area (1 metre radius) with polyethylene sheeting. |
| 5. |
Either |
| a) |
use HEPA vacuum nozzle positioned near tool work area to collect
dust as it is generated or |
| b) |
allow debris to fall onto polyethylene sheeting and immediately
remove by HEPA vacuuming. Use of hand tools is preferable over
power tools where practical. Low speed power tools are preferred
over high-speed tools. |
|
| 6. |
Place
larger materials directly into waste bag trying to avoid dust generation
as possible. |
| 7. |
Use
HEPA vacuum to remove remaining dust. |
| 8. |
Fold
polyethylene floor covering toward centre and dispose of as asbestos
waste together with disposable suits and other debris. Place waste
bag inside second bag and seal. |
| |
|
| Minor
repairs to vinyl floor tiles. |
| 1. |
Vinyl
floor tiles are not inherently dusty and they are not considered to
be friable. |
| 2. |
Use
barricade tape to restrict access to work area. Don respirators. |
| 3. |
Tiles
to be removed (maximum of two in any area) should be pried free from
the adhesive using a suitable pry tool. Try to avoid breakage as possible.
Tiles should be placed directly into asbestos waste bags |
| 4. |
Adhesive
can be removed if needed by |
| a) |
heating
(do not burn) followed by scraping or |
| b) |
by
soaking is suitable solvent followed by scraping. Scraping of
dry adhesive is discouraged. Residue should be placed immediately
in asbestos waste bags. |
|
| 5. |
Area
should then be HEPA vacuumed and allowed to dry if a solvent was used.
Tile replacement does not require asbestos control measures. |
| |
|
| Cleaning
and buffing vinyl floor tiles. |
| 1. |
Buffing
of vinyl floor tiles containing asbestos fibres will generate a small
asbestos aerosol if the buffing is allowed to continue into the vinyl
tile surface. |
| 2. |
Efforts
to avoid buffing beyond the wax layer will reduce asbestos concerns
to negligible. Use of any wet process integral to the buffing will
further reduce asbestos concerns. |
| |
|
| Removal
of fluorescent lamp ballasts with asbestos containing wire wrapping. |
| 1. |
Ballasts
containing asbestos wrapped wires require removal upon failure. The
ballasts are not repaired, only removed and replaced. |
| 2. |
Use
barricade tape to restrict access to work area. |
| 3. |
Don
respirators and, if contact with debris is likely, disposable suits
over street clothes. |
| 4. |
Mist
work area with soapy water ONLY after de-energising
the power supply to the ballast. |
| 5. |
Cover
area beneath work area (1 metre radius) with polyethylene sheeting. |
| 6. |
Carefully
remove ballast including all wiring and place directly into asbestos
waste bag. |
| 7. |
HEPA
vacuum and large bits of asbestos debris that are discovered after
removal of the ballast. |
| 8. |
Damp
wipe metal surfaces within fluorescent tube holding frame using spray
bottle and soapy water. |
| 9. |
Fold
polyethylene floor covering toward centre and dispose of as asbestos
waste together with disposable suits and other debris. Place waste
bag inside second bag and seal. |
