Step-By-Step Instructions
Standard Glovebag Process for Avail Extended-Run glovebags.
Equipment and Supplies Checklist:
1. Avail EXT glovebags
2. Grayling D-Con shower system
3. Disposable coveralls
4. Boot covers
5. Work gloves
6. Hard hat
7. Eye protection
8. HEPA filtered respirator
9. Barricade tape and warning signs
10. Duct tape
11. Smoke test kit
12. Surfactant / wetting agent
13. Encapsulant
14. Pump-up garden type of sprayer
15. HEPA filtered vacuum cleaner
16. 6mil polyethylene drop cloth
17. Asbestos disposal bags
18. Personnel air sampling pumps and cassettes
19. Tools – tin snips, pliers, flexi-saws, box
cutters, brushes, scrub pads, etc.
1. Shut off the HVAC system, or ventilation
fans in the work area and tag and lockout
access to control panels.
2. Mark off the regulated area with barricade
tape, leaving a wide margin around the
abatement area.
3. Post asbestos-warning signs prominently.
4. Erect the D-Con facility adjacent to the regulated area.
5. If there are doors or windows accessing the
regulated area, set up critical barriers.
6. Don your personal protective gear, beginning with the coveralls.
7. Roll out the polyethylene sheeting and
position an adequate length under the pipe
as a drop cloth.
Carfully vacuum the pipe with a
HEPA filtered vacuum cleaner to
remove any asbestos dust.
If the insulation is friable, wrap the
pipe with a layer of polyethylene
sheeting with duct tape in a “candystripe” pattern.
Return to the start of the run. Gather
the open collar of the glovebag
around the pipe and seal it tightly to
the pipe with the duct tape. Repeat
the procedure at the far end of the
Insert the HEPA vacuum and the
the pump sprayer wand through the
entry ports. Seal each to the entry
port socks with duct tape.
Remove the insulation from the
pipe and lower it to the bottom of
the debris area of the bag. Be sure
to remove the insulation that extends
into the collars of the bag.
Clean the pipe as far as possible
between chambers in the collar
area. Once the insulation has been
removed, scrub the pipe clean
using a brush and surfactant.
Place the debris chamber into a
properly marked asbestos disposal
bag and move on to the next chamber
and repeat the process.
Grasp the tools and pull the sleeve
inside out with the tools inside. Twist
the sleeve above the tools and wrap
the twisted area securely with duct
tape, then cut through the center of
the taped area.
After the last chamber of the ExtendedRun Glovebag has been taken down
and safely disposed of, proceed with
clean up and decontamination.
Determine the number of glovebags
required for the project and place
the necessary tools in the tool pouch.
Perform a smoke test on each
chamber prior to commencing
insulation removal. Seal any leaks
detected with duct tape.
Lift the opened bags to the pipe
and tack in place with small strips
of duct tape. Beginning with the first
chamber, seal the bags from one
end to the other with duct tape.
Generously wet the insulation with
surfactant. Put your hands and
arms into the first glove/sleeve
assembly and, using the tools in the
tool pouch, begin removal of the
jacketing and insulation.
Tightly cinch the collar up around
the cleaned section of pipe going
into the next chamber using duct
tape or a strap. Activate the HEPA
vacuum to evacuate the air from
the glovebag.
Twist off the debris chamber just
below the glovesleeves and tightly
wrap the twisted section with duct
tape. Cut through the center of the
duct taped area, separating the
debris chamber from the work area.
Remove all of the glovebag work
area stubs remaining, starting at
the collar, slitting the top of the
stubs free while folding inward into
an asbestos disposal bag.
Again, spray an encapsulant down
the length of the bare pipe to “lock
down” any residual fibers.
