TITLE:
Asbestos Removal Work Practices
PURPOSE:

The purpose of this policy is to set forth criteria for safe
working procedures in jobs involving the handling of asbestos
in accordance with the OSHA Asbestos Standard 1910.1001.
ASBESTOS REMOVAL WORK PRACTICES:
A. Small-Scale, Short-Duration Activities
Small-scale, short-duration renovation and maintenance
activities are tasks such as, but not limited to:
1.
Small-Scale
Removal of asbestos containing insulation on pipes,
valves and flanges.
Removal of small quantities
material on beams.
of
asbestos
containing
Quantity - 1 cubic yard or less which equals to four 55
gallon drums.
NOTE: The quantity figure
E.P.A. guidelines.
2.
is
established
under
the
Short-Duration
Activities that can be performed within or below the
(TWA) time-weighted average of an 8-hour shift.
B. Large-Scale Activities (Abatement Project)
Large-scale abatement activities consist of removing
quantities of asbestos containing insulation material greater
than 1 cubic yard or more than four 55 gallon drums.


1.
A proper 2" x 2" sample shall be taken and sent to a lab
for analysis.
2.
Prior to any removal, the proper State agencies must be
notified. The contractor shall receive a copy of the
notification permitting the removal prior to the start of
the process.
3.
Prior to the removal process, the asbestos removal team
shall have:
a.
A current annual physical by a physician.
b.
A current respirator fit test and proper training.
c.
Proof of current asbestos training
direction of a certified instructor.
d.
Information on the job scope.
e.
All the necessary safety supplies, equipment and
tools to perform the job safely.
under
the
4.
A certified competent person will be on the job site at
all times and write a letter of feasibility if needed.
The certified competent person is responsible for
selecting the safest and most feasible method for removal
of the asbestos.
5.
During the asbestos removal process, employee exposure
monitoring shall be conducted. When all employees within
the regulated area are equipped with supplied-air
respirators operated in the positive-pressure mode,
exposure monitoring may not be required.
6.
Regardless of the abatement method used, a regulated area
shall bear the proper warning signs visible from all
angles.

D. Methods of Compliance - The Removal of Asbestos

There are four acceptable methods for the safe removal of
asbestos. They are the Glove Bag Method, Mini-Enclosure,
Removal of Entire Structures, and Full Enclosure under
Negative Pressure.
Regardless of the method used for removal, the following
items and personal protective equipment are considered
mandatory:

Glove Bag Practices - Small Scale/Short Duration
a.
Glove bags are approximately 40" wide by 64" long
fitted with arms by which the work can be performed.
b.
Glove bags shall be installed so that they completely
cover the asbestos to be removed.
c.
All openings shall be sealed with duct tape and the
bottom seam shall be taped to prevent any leaks.
d.
Thoroughly wet the asbestos material with the garden
sprayer using the slot in the glove bag.
e.
Use the required tools to remove the asbestos
material using care not to cut the plastic bag with
any sharp objects.
f.
After the asbestos has been removed, wash down the
surface with water and scrub with the nylon brush.
g.
The work area shall be cleaned and free of all
asbestos material.
h.
Rinse off the tools and pull them through the fitted
arms.
i.
Remove the pump sprayer nozzle and insert the HEPA
vacuum to draw out all excess air. Squeeze the bag
and compact it tightly to assure removal of air.
j.
Cut the fitted arm close to the end, remove any tools
and tape the bag shut.
k.
Remove the bag from the structure, then remove the
vacuum hose and use the "goose-neck" method to twist
and seal the upper part of the bag.

l.
Dispose of the bag ONLY in the designated 55 gallon
drum or dumpster.
m.
Employees are required to vacuum off their suits and
respirators, and wash their respirator with water
before removing it to eat or drink/and or leaving the
regulated area.
n.
Employees are required to shower at the completion of
the abatement.
Mini Enclosure Practice - Small Scale/Shift Duration
a.
The mini-enclosure shall be constructed on all four
sides, top and floor of double layered 6 mil
polyethylene plastic supported by area structures.
The area should be small enough to restrict entry to
two (2) asbestos workers and their equipment.
b.
A change room shall be constructed and should be
contiguous to the mini-enclosure. This change room
will allow the worker to vacuum off his protective
coveralls and respirator prior to leaving the area.
c.
The asbestos material shall be removed using the wet
method. In cases where removal is performed on or
near live electrical equipment or areas where water
will seriously damage the surrounding area, a nonconductive wetting agent shall be used.
d.
The work area shall be clean and free of all asbestos
materials prior to removing the enclosure.
e.
The employee must vacuum his suit and wash their
respirator with clean water before removing it.
f.
Employees are required to shower upon leaving the
work area.

Removal of Entire Structures
a.
The asbestos-containing insulation shall be wrapped
with double layered 6 mil polyethylene plastic and
securely sealed with duct tape.
b.
If a pipe is completely insulated with asbestoscontaining materials, small sections should be
stripped using the glove bag method. These stripped
areas shall be used to cut the pipe into smaller
pieces for transit.
4. Full Enclosure Practices using Negative Pressure
a.
The enclosure shall be constructed on all four sides,
top and floor of double layered 6 mil polyethylene
plastic supported by the area structures or
additional 2" x 4" supports. All openings shall be
sealed with duct tape.
b.
A hygiene facility shall be constructed and should be
contiguous to the enclosure.
This facility shall
consist of three chambers. The dirty chamber shall be
adjacent to the area where the work is to be done. A
shower chamber shall be connected to the dirty
chamber, and lastly, a clean chamber shall be next in
line for storage of "street clothes". The certified
competent person shall ensure proper erection of the
hygiene facility.
c.
An initial air sample shall be taken after negative
pressure is obtained within the enclosure.
d.
Once the negative air pressure machine is turned on
to begin the asbestos striping, it must operate 24
hours per day.
The primary and secondary filters
must be changed as described by the manufacturer.

taken for 30 minutes and processed by a lab.
g.
The work area shall be clean and free of all asbestos
materials prior to removing the enclosure.
h.
After all asbestos removal work and the final cleanup
is completed, the negative pressure air machine shall
be turned off.
i.
