Introduction

The Asbestos Control Program is a set of practices and procedures applied to building cleaning, maintenance, construction, renovation and general operation in order to maintain the building. The Asbestos Control Program applies to all UNC construction and maintenance personnel including Architectural and Engineering Services, Facilities Planning, Construction Services and Energy Services. The goal at UNC is to: 1) manage the asbestos containing materials (ACM) in UNC buildings to ensure that exposures to personnel and the environment are minimized and are below the OSHA permissible exposure limit (PEL); 2) ensure that all removal and disposal of ACM complies with all local, state and federal regulations; and, 3) maintain records of surveys, monitoring activities, maintenance activities involving ACM, and personnel exposure. This program is administered by the Department of Environment, Health and Safety. The following individuals oversee the program:

  • Industrial Hygiene Support: Environment, Health and Safety
  • Asbestos Supervisor for Facilities: Supervisor of the Insulation Shop for Campus and Service Shops
  • Asbestos Supervisor for Housing Support: Supervisor of the Electrical Shop 597

    4. Under some circumstances buildings may be damaged (high winds, tornados, hurricanes, fires, explosions) which may require immediate actions for cleanup. Under these circumstances if it is known that no ACM has been disturbed, then proceed with clean-up. If ACM is known or highly suspected, contact EHS or A&E Construction Department to assist in determining the proper course of action.

Maintenance Procedures

Employees performing maintenance activities under OSHA Class IV that result in contact with ACM (but no disturbance) or employees performing maintenance activities under OSHA Class II intact or nonfriable or Class III nonintact or friable must adhere to the following guidelines:

  • Do not drill holes or saw in ACM
  • Do not sand, grind, cut, or abrade ACM. Do not use high speed buffers on floor tile
  • Do not install partitions or dividers in such a way that they will damage the floor tile, ceiling tiles or plaster ceiling
  • Do not use an ordinary vacuum to clean friable ACM debris. Class IV workers including custodial and maintenance staff employees should report the minor fiber release episode to their supervisor immediately. The supervisor will be responsible for contacting one of the Asbestos Supervisors for cleanup of the debris. Cleanup operations involving ACM should only be performed with HEPA Vacuum.
  • During the removal of intact floor tiles, avoid breakage to reduce the potential for the release of fibers. (Use 16-Hour O & M trained personnel or asbestos supervisors to perform these tasks.)
  • ACM waste must be disposed of in 6 mil polyethylene bags with the proper NESHAP (Waste Generator Label), DOT (Placard) and OSHA (Danger) labeling requirements and transported to the temporary storage dumpster located at the Physical Plant.
  • Documentation of waste must be submitted to shop supervisor.

When maintenance activities are required which may involve the disturbance of more than 25 linear feet of TSI, 10 square feet of surfacing material (utilizing a mini enclosure only) or 160 square feet of miscellaneous materials excluding flooring material, the work shall be contracted to an approved licensed asbestos abatement contractor.

When any outside contractor (electrician, HVAC, etc.) performs work that may involve the disturbance of the ACM identified in the building, the appropriate manager (such as the UNC-CH Construction Manager, Maintenance Supervisor, or other entity) that has hired the contractor must inform the Contractor of the existence of ACM. The designated person will inform the Contractor of the hazards associated with asbestos exposure. Confirming the identity of ACM which may be impacted by a project will include a review of the asbestos building inspection documents by EHS representative. The UNC-CH Construction Manager, Maintenance Supervisor or Building Administrator shall inform the building occupants of the project and the measures being taken to protect against airborne fiber release. The contractor is responsible for informing and insuring his/her employees and any subcontractors that all applicable regulatory requirements are met.

Specific Work Practice Procedures: Refer to Appendix D for the Compliance Chart for the OSHA Construction Industry Asbestos Standard for specific requirements for the various classes of work.

All work practices must follow OSHA’s Three Key Rules for all Work:

  1. Use wet methods
  2. HEPA vacuum
  3. Prompt cleanup

A. Removal of Thermal System Insulation Utilizing a Glovebag

The following work practice procedures shall be followed during the removal of pipe insulation (In occupied areas, this method should be performed after normal business hours) under Class I, II or III work activities. Please note that Class III workers (ASBESTOS O&M Trained) cannot remove more than one standard glovebag (60″ x 60″) of TSI.

  1. Check the temperature of the pipe to ensure that it does not exceed 150° Fahrenheit. Note: High temperature glovebags may be required for steam lines exceeding 150° Fahrenheit.
  2. Install critical barriers on all HVAC ductwork, floor drains and other openings and place the danger signs and barrier tape around the regulated work area.
  3. Don respirator and disposable suit. Perform negative and positive pressure fit check.
  4. Place a layer of 6 mil polyethylene sheeting beneath the work area.
  5. If necessary, cut approximately a foot down the sides of the glovebag and place the tools in the pouch.
  6. Wrap tape around the pipe where you will attach the bag. Tape the bag closed.
  7. Cut two small holes in the bag and insert the nozzles of the HEPA vac and the sprayer. Seal the openings with duct tape.
  8. Smoke test the glovebag to insure that it is sealed airtight.
  9. Spray the insulation with amended water, being sure to soak the area to be cut.
  10. Cut the insulation with a saw or knife at each end of the section to be removed. Cut it lengthwise along the bottom with a knife.
  11. Break the insulation away from the pipe and lower it to the bottom of the bag.
  12. Spray the insulation with amended water to wash any asbestos to the bottom of the bag.
  13. Spray, scrub, and wipe the exposed pipe to remove any asbestos on the pipe. Use a brush with nylon or fiber bristles. Spray lockdown on the pipe.
  14. Grab the tools in your hands and pull the gloves inside out. Remove the rest of the air in the bag by briefly turning on the HEPA vac. Twist the sleeve and tie it off with two pieces of duct tape. Cut the sleeve between the tape at the twist. Put the sleeve containing the tools in the next glovebag to be used or open it in a pail of water for cleaning.
  15. Turn the HEPA vacuum on again. Twist the bag below the pipe and tape it closed.
  16. Slip a large plastic asbestos disposal bag around the glovebag. Remove the glovebag from the pipe and fold it into the disposal bag. Seal and label the bag.
  17. Apply encapsulant paint on the cut edges of the asbestos pipe and apply a canvas cloth to seal the open ends.
  18. Vacuum the work area, step to the decontamination area and vacuum your clothing.
  19. Remove and wipe your respirator with a damp cloth. Remove your suite inside out and place it in an asbestos disposal bag with contaminated rags, used filters, and decontamination plastic sheeting. Seal and label the bag for disposal.

  21. Remove barrier tape and signage from the work area.
  22. Transport waste to the storage facility (thru The Asbestos Supervisor for Facilities).

B. Drilling into ACM

  1. If possible, shut off the HVAC system serving the work area and install critical barriers.
  2. Mark the drilling location.
  3. Don respirator, disposable gloves and disposable suit. Perform negative and positive pressure fit check. (Once a NEA is established, the PPE with the exception of the non-porous disposable gloves can be omitted from the requirements.)
  4. Pre-clean work area if visible dust or debris is present with amended water and/or HEPA vacuum.
  5. Place a drop cloth of 6 mil polyethylene sheeting beneath the work area.
  6. Fill a paper cup with shaving cream and apply the shaving cream side down to the substrate.
  7. Drill through the surface and remove the drill bit being sure to clean with a wet wipe or water.
  8. Wipe the shaving cream off the surface with a wet wipe and place it in disposal bag.
  9. If debris falls to the ground, either wet wipe, HEPA vacuum and/or dispose in an asbestos disposal bag.
  10. Dispose of gloves in the asbestos waste bag.
  11. Transport waste to the storage facility (thru The Asbestos Supervisor for Facilities).

C. Mini Enclosure (Plastic Closet)

The mini enclosure should be sized to house a maximum of two workers.

  1. If possible, shut off the HVAC system serving the work area.
  2. Install critical barriers on all HVAC ductwork, floor drains and other openings and place the danger signs and barrier tape around the regulated work area.
  3. Construct the mini enclosure from polyvinylchloride (PVC) piping and line with two layers of 6 mil poly. Place a small layer of poly on the ground outside of the containment as decontamination area.
  4. Smoke test the enclosure
  5. Create an opening in the enclosure and add protective flaps over the opening.
  6. Install a HEPA vacuum to the enclosure placing the vacuum on the opposite side of the entrance opening. The HEPA vacuum functions as the negative air machine.
  7. Install tools needed to perform the abatement.
  8. Don respirator, disposable gloves (optional) and two disposable suits.
  9. Apply the amended water to the ACM using a garden sprayer. Remove no more than the amount held by one waste bag.
  10. Place the material in an asbestos disposable bag (double bagged) and remove from the mini enclosure after wiping down.
  11. HEPA vacuum and wet wipe the interior surfaces of the mini enclosure.
  12. Apply lockdown to all of the surfaces within the mini enclosure.
  13. Upon completion, clean off the outside suit with a HEPA vacuum.
  14. Remove the outside suit by rolling the suit inside out and place it in a disposable bag. Step on to decontamination area outside the mini containment and remove the remaining suit while wearing the respirator.
  15. Thoroughly wash the respirator and hands after exiting.
  16. Contact EHS to conduct monitoring and/or visual inspection of the work area.
  17. Once the lockdown has dried, tear down the mini enclosure and place the polyethylene sheeting in waste bags.
  18. Transport waste to the storage facility (thru The Asbestos Supervisor for Facilities).

D. Removal of Flooring Material and Mastic Utilizing Non-Friable Removal Techniques (Class II)

  5. If the mastic is scheduled to be removed, remove the baseboards and tape a two foot wide layer of 4-6 mi poly along the base of the walls as a splashguard while removing the mastic.
  6. Using a heat gun or an infrared heat machine, heat the tiles and remove using a mason’s trowel. Exception: If the flooring material was identified as being damaged and brittle, do not use heat and gently remove the tiles and place them in a sealed bag.
  7. Class III Workers (ASBESTOS O&M Trained) can only abate the amount of material that will fit in one waste bag if the flooring material is friable.
  8. Place the tiles in cardboard boxes and then place into the disposable bag in order to prevent puncturing the disposal bags. Seal the bags with the goose neck seal.
  9. If removing more than 160 square feet of non-friable flooring material, contact EHS to determine if air monitoring and/or visual inspection is necessary.
  10. Transport the waste to the temporary storage facility maintained by The Asbestos Supervisor for Facilities.

E. Principles of Containment and Personal Protection

When performing asbestos abatement activities, the following containment and personal protection practices are to be followed:

  1. Personnel are to wear a minimum of a half face cartridge respirator equipped with a HEPA (P100) filter. Use a glove bag for removal of TSI.
  2. Plastic sheeting is to be used as a drop cloth on the floor below any TSI and surfacing material that is to be removed.
  3. A step-off drop cloth of polyethylene sheeting is to be placed adjunct to all work areas as a decontamination area.
  4. Wet methods of ACM removal are to be used to minimize airborne asbestos. Exception: If dry removal has been approved due to electrical or other safety hazard.
  5. The room or area must be isolated from the building ventilation system.
  6. Enclosures under negative pressure are to be constructed to isolate the ACM removal from other areas of the building.
  7. Warning signs are to be posted outside the room or enclosure with the following information: “Danger, asbestos cancer and disease hazard; authorized personnel only; respirators and protective clothing are required in this area.”
  8. Surfaces potentially contaminated with ACM are to be cleaned using wet methods or a HEPA vacuum.
  9. Contaminated waste is to be placed in sealed, doubled 6 mil bags or other approved leak-tight containers and transported to the temporary storage area at Facilities Services.

(See Appendix D-Compliance Chart)

Internal Inspections & Inspections of Outside Contractor Work

Annual visual inspections are conducted for buildings containing known friable sprayed-applied asbestos fireproofing. The inspection consists of an evaluation of the condition of the sprayed-on surfacing material and air monitoring to determine if there are building occupant exposures above the limit for public areas (0.01 f/cc). Hamilton Hall contains friable spray-applied asbestos fireproofing.

The following steps shall be required by EHS:

  1. Contact department/building representative to coordinate the sampling locations and time.
  2. Calibrate air-sampling equipment.
  3. An air sample is collected on a cellulose ester membrane filter. Approximately 400 – 2400 liters of air will be collected per OSHA nonmandatory Appendix B. The time of sample and calculation of sample volume are recorded on the sample data sheet and on the 25 mm cassette containing the sample filter.
  4. The condition of the ACM is evaluated for physical damage, water damage, deterioration, and the potential for disturbance due to accessibility of building occupants. Also, any activities that could disturb the ACM are documented and evaluated for employee exposures.
  5. An inspection report, including air monitoring results, is prepared and sent to department / building representatives.

Inspection of Class I and II Asbestos Work Performed by an Outside Contractor

Large (>25 linear feet of TSI, >10 square feet of surfacing material) Class I and II asbestos work on campus shall be performed by outside contractors. These removal projects shall be periodically inspected by EHS. EHS shall inspect large Class I and II removal projects by participating in the pre-work containment visual, conduct periodic site visits, and participate in the final visual inspection prior to clearance testing. The Building Construction Management shall inform the project design firm and/or the air monitoring professional that EHS must be contacted to participate in the prework containment visual and to conduct a visual inspection prior to clearance testing.

Warning Signs

OSHA Construction Standard 1926.1101 (k) (6) requires that signs be posted at the entrance to mechanical rooms/areas in which employees reasonably can be expected to enter and which contain ACM and/or PACM. The signs are to include location, identification of material, and appropriate work practices to prevent disturbance. Signs are to be in comprehendible languages.

The sign for asbestos thermal systems insulation material reads as follows:

WARNING!

Some of the pipe insulation and other thermal system insulation in this room contain asbestos. Avoid creating dust from any insulation. If disturbance of this material is anticipated during any work task then contact the Environment, Health and Safety (962-5507) prior to beginning work.

The sign for asbestos surfacing material reads as follows:

WARNING!

This ceiling surface contains asbestos. Avoid contact or disturbance of the surfacing material on this ceiling. If disturbance of this material is anticipated during any task, contact the Environment, Health and Safety (962-5507) prior to beginning work.

Inspection of Housekeeping Buffing Operations

According to OSHA regulations Housekeeping buffers used for stripping floor wax from vinyl asbestos floor tiles must not operate above 300 RPM. Wet methods and low abrasion floor pads are also to be used. Periodic inspections of housekeeping personnel are conducted to ensure that these requirements are followed.

Employee Exposure Assessment and Monitoring

OSHA regulations require that each employer who has a workplace or work operation covered by the standard shall perform monitoring to determine accurately the airborne concentrations of asbestos to which employees may be exposed. These must be breathing zone air samples representative of 8-hour time-weighted average and 30-minute short-term exposures. The following work operations should be reported to EHS to determine if exposure monitoring is necessary:

  • Glove bag removal of TSI
  • Clean up of damaged friable ACM (TSI or surfacing material) that has fallen to the floor or other horizontal surfaces
  • Repair and/or removal of small amounts of surfacing ACM for maintenance activities or construction activities
  • Removal of drywall, tape and spackling compounds
  • Removal and/or replacement of ceiling tiles
  • Removal of window glazing
  • Repair and/or removal of damaged transite material
  • Repair, removal or disturbance of insulation within fire doors (unless the entire door component is being removed and disposed of properly)
  • Repair and/or removal of roofing materials with the exception of flashing, coatings, adhesives and mastics
  • Repair and/or removal of other miscellaneous materials as required by EHS

Employee Complaints

  1. Complaints relating to potential asbestos exposure filed by building occupants shall be reported to EHS.
  2. EHS shall inspected their work area and evaluate their potential for exposure.
  3. The evaluation may require the EHS representative to collect a bulk sample to determine if the material contains asbestos.
  4. The EHS representative shall perform air monitoring if there is any disturbance of ACM that could result in personnel exposure to airborne asbestos.
  5. Examples of complaints include: ceiling material falling onto an employee’s desk, questions about containment during an ACM removal project, damaged ACM debris on the floor; employees encounter potential ACM during the performance of their duties and have questions about their potential exposures.
  6. A written report of the investigation is maintained by EHS with a copy being sent to the employee.
