Current through Register Vol. 48, No. 9, September 27, 2024

A. Applicability.

1. The requirements of this Section shall apply to the owner/operator of any NESHAP, small, minor, or O&M abatement project when glovebag operations are implemented.

2. The owner/operator shall ensure that asbestos-containing waste from glovebag operations is wet at all times during abatement, storage, and transportation and is deposited in a landfill approved or permitted to accept asbestos waste.

B. Glovebag Operations.

Glovebag systems may be used to remove ACM from straight runs of piping, elbows, and other connections when performed in compliance with the provisions of this Section and OSHA 29 CFR 1926.1101, as amended, and any subsequent amendments and editions.

1. The owner/operator shall ensure that the glovebag is constructed and utilized in accordance with the following requirements:
a. The work area is isolated to prevent access by unprotected persons.

b. Danger signs are displayed at all approaches to any asbestos abatement area in accordance with OSHA 29 CFR 1926.1101, as amended, and any subsequent amendments and editions.

c. The glovebag procedure is performed only by persons who have received training in the method and are licensed as workers or supervisors in accordance with the requirements of this regulation.

d. At least two persons shall perform glovebag removal operations.

e. Each glovebag shall be made of 6-mil thick plastic and shall be seamless at the bottom.

f. Each glovebag used on elbows and other connections must be designed for that purpose and used without modifications.

g. Each glovebag shall be installed so that it completely covers the circumference of pipe or other structures where the work is to be performed.

h. Each glovebag shall be smoke-tested for leaks and any leaks sealed prior to use.

i. A glovebag shall be used only once and may not be slid or moved.

j. Each glovebag shall not be used on surfaces whose temperature exceeds 150 degrees Fahrenheit.

k. Prior to disposal, each glovebag shall be collapsed by removing air within it using a HEPA vacuum.

l. Before beginning the operation, loose and friable material adjacent to the glovebag or glovebox operation shall be wrapped and sealed in at least two layers of 6-mil polyethylene.

m. Where a system uses an attached waste bag, such bag shall be connected to the collection bag using a hose or other material that shall withstand the pressure of ACM waste and water without losing its integrity.

n. A sliding valve or other device shall separate the waste bag from the hose to ensure no exposure when the waste bag is disconnected.

C. Negative Pressure Glovebag Systems.

1. Negative pressure glovebag systems shall be used to remove ACM from piping.

2. In addition to the requirements for glovebag systems in Section B above, negative pressure glovebag systems shall have a HEPA vacuum attached to the glovebag/box to prevent collapse during removal.

3. A HEPA vacuum shall be used to prevent collapse of the bag during removal and shall run continually until completion of operation, at which time the pipe shall be encapsulated, and the bag and ACM shall be isolated prior to removal of the bag from the pipe.

D. Negative Pressure Glovebox Systems.

Negative pressure gloveboxes may be used to remove ACM from pipe runs when the following work practices are utilized:

1. Gloveboxes shall be constructed with rigid sides and made from metal or other material that can withstand the weight of the ACM and water used during removal.

2. A negative pressure generator shall be used to create negative pressure in the system.

3. An air filtration unit shall be attached to the box.

4. The box shall be fitted with gloved apertures:
a. An aperture at the base of the box shall serve as a bagging outlet for waste ACM and water.

b. A back-up generator shall be present on site.

c. Waste bags shall consist of 6-mil or thicker plastic and be double-bagged before they are filled.

5. At least two persons shall perform the removal.

6. The box shall be smoke-tested for leaks and any leaks sealed prior to use.

7. Loose or damaged ACM adjacent to the box shall be wrapped and sealed in at least two layers of 6-mil or thicker plastic prior to the job or otherwise made intact prior to the job.

8. A HEPA filtration system shall be used to maintain pressure barrier in the box.

E. Air Sampling and Analysis Procedures.

1. Background and daily area monitoring shall be performed for all NESHAP glovebag/glovebox projects. Personnel air sampling in the worker's breathing zone may be used to satisfy the requirement for daily area monitoring.

2. Non-aggressive Phase Contrast Microscopy (PCM) clearance air monitoring shall, at a minimum, be required for NESHAP and small glovebag or glovebox projects.

3. If personnel fiber counts exceed the PCM clearance standard of 0.01 fibers per cubic centimeter, aggressive clearance air monitoring shall be performed.

F. Glovebag/Glovebox Work Practices.

1. Use of the glovebag shall be terminated, cleanup procedures contained in this Section shall be implemented, and clearance by TEM analysis performed if the owner/operator:
a. Fails to keep RACM in the glovebag/glovebox;

b. Fails to keep RACM adequately wet;

c. Disturbs or dislodges RACM outside of the glovebag/glovebox; and/or

d. Experiences glovebag failure, including any breach in the glovebag/glovebox.

2. Glovebag/Glovebox Clean-up. Following removal, the owner/operator shall ensure that:
a. Porous surfaces that have been stripped or cleaned of RACM are encapsulated to secure any residual fibers that may be present prior to removing the glovebag or glovebox from the abated pipe. The encapsulant used must be compatible with subsequent coverings.

b. All polyethylene sheeting, tape, glovebags or gloveboxes and other equipment must be removed and the area inspected for visible residue.

c. Wet-cleaning using amended water is performed, followed by HEPA vacuuming after surfaces have been allowed to dry. The sequence of wet cleaning and vacuuming shall be repeated until no visible residue is observed in the work area.

d. When required, final TEM air clearance shall be performed following visual clearance.

G. Disposal.

All applicable disposal requirements of this regulation shall apply.
