Section 56-8.3 Minor asbestos projects
- Vacation of work areas.
All project areas shall be vacated by the occupants prior to work area preparation and until full abatement has been achieved.
- Isolation of work area.
The project area shall be isolated by cordoning it off with barrier tape or line and shall be accessible through only one entrance/exit.
Caution signs shall be posted at any location and approaches to a location wherever airborne concentrations of asbestos may exceed ambient background levels. Signs shall be posted that permit a person to read the sign and take the necessary protective measures to avoid exposure.
56-15.4 Minor asbestos projects
If a glovebag or tent is used and fails or loses its integrity, the following procedures shall be required:
- Isolation barrier construction.
An isolation barrier shall be constructed as follows:
- HVAC isolation.
The HVAC systems shall be shut down immediately and all openings shall be sealed with at least six-mil fire-retardant plastic sheeting and duct tape.
- Uncontaminated areas.
Passageways to uncontaminated areas of the building or structure shall be sealed with at least six-mil fire-retardant plastic sheeting and duct tape.
- Negative air pressure equipment ventilation.
Negative air pressure equipment ventilation that complies with Subpart 56-6 of this Part shall be installed and utilized.
Cleanup shall be accomplished as follows:
- Method, tools and equipment.
All accumulations of asbestos waste material shall be containerized. Metal shovels or HEPA vacuums may be used to pick up or move waste, except in the vicinity of any isolation barriers which could be breached. The areas around the isolation barriers shall be cleaned utilizing rubber or plastic dust pans, squeegees or shovels. HEPA vacuums shall be used to clean all surfaces after gross cleanup.
- Cleanup of surfaces.
All surfaces in the work area shall be first wet-cleaned using rages, mops and sponges.
- Second cleaning.
After the first cleaning, at least 12 hours shall be allowed for asbestos to settle. Thereafter, all objects and surfaces in the work area shall be HEPA-vacuumed and/or wet-cleaned. The isolation barrier shall be breached for entry and exit with minimal frequency and shall be resealed immediately. All windows, doors, HVAC system vents and all other openings shall remain sealed.
- Removal of contaminated equipment and waste.
Contaminated equipment and all containerized waste shall be removed from the work area.
- Clearance air monitoring.
Clearance air monitoring, as per the schedule for air sampling and analysis shall be conducted.
- Removal of isolation barrier.
The isolation barrier shall be removed only after satisfactory clearance air monitoring results have been achieved.

Subpart 56-16 Minor Project Procedures
Section 56-16.1 General requirements
Corrective actions shall be performed using nonasbestos material. Such actions shall include enclosure patch-up, spot removal, spot patch-up and spot encapsulation.
- (b) Glovebag use.
Glovebag operations shall be performed using commercially available glovebags of at least six mil, transparent plastic and no larger than needed.
When abating pipe insulation, the pipe insulation diameter worked shall not exceed one half the bag working length.
Duct tape shall be placed securely around the affected area to form a smooth seal. The glovebag shall then be secured to the duct tape and sealed airtight.
- Seal testing.
The glovebag seal shall be subjected to and pass a smoke test a follows:
- Aspirate the contents of a smoke tube through the water port access of the bag.
- After twist-sealing the access port, the bag shall be squeezed gently and checked for any leakage points, which shall be taped airtight.
- Surface irregularities.
If the material adjacent to the work section is damaged, or if it terminates, is jointed or contains an irregularity adjacent to the work section, the material shall be wrapped in at least six-mil fire-retardant plastic sheeting and sealed airtight with duct tape.
- Amended water.
All asbestos material within the secured glovebag shall be wetted with amended water prior to stripping.
- Post-stripping wetting.
After the asbestos material has been stripped, the surfaces from which it has been removed shall be saturated with amended water and scrubbed with a brush to remove all visible asbestos material. The surfaces from which it has been removed, the interior of the gab, the affected area and tools shall then be thoroughly wetted with amended water.
- Sealing of pipe ends.
When abating pipe insulation, any pipe insulation ends created shall be sealed with wettable cloth, end caps, spray glue or any compatible combination of these.
- Collapsing of the glovebag.
A HEPA vacuum shall be used to collapse the glovebag.
- Tool segregation.
With the glovebag collapsed and the asbestos material in the bottom of the bag, twist the bag several times and tape the twist to seal that section. The tool pouch shall be separated from the bag by twisting it several times, taping the twist and thus sealing the pouch. Alternatively, the tools may be pulled through with one or both glove inserts, thus turning the gloves inside out. The gloves shall then be twisted several times, taped and thus sealed.
- Containerizing the glovebag.
At least a six-mil plastic bag shall be used to contain the glovebag while it is still attached to the affected area. The bag shall then be detached from the affected area by removing the duct tape.
- Sealing of contaminated items.
The glovebag shall be placed into at least a six-mil plastic bag, sealed airtight and removed from the project area for disposal.
- Tent Construction.
Corrective actions on area emplaced asbestos material shall be performed using a constructed or commercially available plastic tent. The tent shall be of at least six-mil fire retardant plastic sheeting with double-folded seams. Seams shall be taped airtight and then taped flush with the adjacent tent wall. (Wall and floor layers overlap, ceiling and walls.)
- Tent use.
When utilizing a tent, the following shall be required:
- Personal protective equipment.
Persons shall don disposable protective clothing. Authorized visitors entering the tent shall first don NIOSH-approved respiratory protection.
- Exhausting the tent.
A HEPA vacuum shall be used to continuously exhaust the tent.
- Amended water.
All material to be removed shall be saturated with amended water as specified in this Part. (Surfactant.)
- Abatement procedures.
Asbestos material shall be removed and sealed in plastic bags prior to removal from the tent. Edges of asbestos material remaining shall be encapsulated or sealed with wettable cloth.
The entire project area and the plastic tent (and self) shall be wet cleaned. The HEPA vacuum shall be operated for a minimum of 20 minutes following completion of the wet cleaning. (Self stays in.)
- Sealing of surfaces and edges.
The substrate from which asbestos was removed and any exposed edges shall be sealed with encapsulant.
- Removal of personal protective equipment.
The persons' disposable protective clothing shall be removed and left in the tent upon exiting.
- Exiting procedures.
After exiting the tent, persons shall immediately don clean protective clothing. Persons shall then seal the tent exit and, upon tent collapse, shut down the HEPA vacuum.
- Collapsing and containerizing the tent.
The plastic sheeting which formed the tent, and the contents thereof, shall be fully collapsed, starting from the top and working downward. The tent and contents shall be placed in at least a six-mil plastic bag or hard wall container, sealed with duct tape and removed for disposal.
Persons shall proceed immediately to a shower for decontamination.
