30.1 Introduction

The impetus for compiling the NASA Ames Asbestos Management Plan derives from the need to comply with over seven major governmental regulations and guidance documents published by governmental institutions. The NASA Ames Asbestos Management Plan is an effort to streamline these compliance documents into a logical and economically efficient plan.

The Ames Asbestos Management Plan integrates applicable Federal, State, and local regulatory agency requirements and NASA policy governing asbestos-related work. It addresses any operation, including maintenance activities, involving potential or actual disturbance of materials that contain asbestos. All contractors/subcontractors who conduct asbestos-related work located on NASA property must adhere to all requirements set forth in the Ames Asbestos Management Plan.

30.2 Purpose

NASA Ames Research Center (ARC) has established the Ames Asbestos Management Plan to address a variety of issues regarding asbestos-related work. The goals of the Ames Asbestos Management Plan are to:

1. Minimize exposure of employees, visitors, and contractors of NASA Ames Research Center to airborne asbestos.
2. Comply with all pertinent, regulatory, and NASA requirements related to asbestos-containing materials. ARC recognizes and will comply with all applicable Federal, State, and local governing regulatory agency regulations/guidelines pertaining to asbestos-containing materials.
3. Establish procedures for the identification, evaluation, control, maintenance, disturbance, abatement, and waste storage/disposal of asbestos-containing material at ARC.
4. Remove, enclose, encapsulate, or repair hazardous asbestos-containing material as required by government or NASA regulations, and as needed to protect human health.
5. Provide asbestos awareness training.
6. Provide certified asbestos consultants to evaluate potential asbestos-related hazards, sample suspect materials, and oversee asbestos-abatement projects.
7. Eliminate the installation of new asbestos-containing material whenever possible.
8. Ensure that asbestos-related contracted/subcontracted work is properly planned, reviewed, and conducted.

6. All hazardous waste generated and transported from NASA property must have a hazardous waste manifest signed by the Environmental Services Office prior to transportation.

30.11 Operations & Maintenance (O&M) Activities

The principal objective of an operations and maintenance program is to minimize potential exposure to airborne asbestos fibers of all building occupants and maintenance personnel. Individuals involved in an operations and maintenance program are employees who are in casual and nonintentional contact with asbestos because of the nature of their work or mere presence in a building. To accomplish this objective, an operations and maintenance (O&M) program shall include work practices to:

The implementation of the O&M Program is the primary responsibility of the NASA ARC groups that are responsible for maintenance activities such as the Facilities Engineering and Plant Engineering Offices. NASA ARC's O&M Program includes the following elements:

The goal of the notification is to avoid disturbing asbestos-containing material through communication of potential hazards. The idea is that informed persons are less likely to unknowingly disturb the material and cause fibers to be released into the air. The notification either shall be in writing, or shall consist of a personal communication between NASA and the person to whom notification must be given, or his/her authorized representative. The NASA Safety Office (in coordination with the building managers and supervisors) will periodically notify the following groups of the presence, location, and quantity of ACM or PACM at the work sites in NASA buildings and facilities:

30.11.1.1 Posting Signs for Areas or Buildings that Contain Asbestos

Areas or buildings found to contain asbestos shall be posted with a warning notice that is readily comprehended, indicating the presence of asbestos, its location, and work practices that ensure that it will not be disturbed. An example of suitable sign format and content is shown in Appendix C (see section 30.14.3). At a minimum, these signs will be posted at the entrance to mechanical rooms/areas in which employees reasonably can be expected to enter and that contain ACM/PACM.

30.11.1.2 Installed Asbestos-Containing Materials Notification

Warning labels/signs will be posted (with assistance from facilities engineering), where feasible, on installed friable asbestos-containing materials that are accessible to employees, contractors, or the general public. (see Appendix D section 30.14.4).

30.11.1.3 Contractors Notification

All successful bidding contractors (regardless of the contract amount) will be provided with a written Asbestos Notification Summary at the time a contract is awarded. The Asbestos Notification Summary should list the location and condition of ACM. It is the responsibility of the NASA Acquisition Office as well as all contractors to provide the Asbestos Notification Summary in all contracts.

All NASA ARC-Moffett buildings constructed as of January 1987 have had a preliminary evaluation for the presence of ACM. This Centerwide building evaluation consisted of both the identification of specific ACM components and an assessment as to the hazard that such materials may present to NASA ARC employees and contractor personnel. The documentation of this survey resides in the NASA Safety Office and is available for review by engineers and other personnel who may need to know the location of ACM or PACM. Information from the survey should be used only to supplement new survey data collected with new sampling and analytical protocols.

Conditions, accessibility, use factors, etc. are likely to change over time. Therefore, ACMs require periodic reassessment to determine if changes have occurred that warrant reassessment to a different hazard class.

30.11.3.1 Reassessment Procedure

As deemed appropriate, the Safety Office will perform visual AHERA type assessments using AHERA classifications and definitions of NASA buildings and facilities to assess any changes in the condition of ACMs and PACMs. All assessments will be conducted in accordance with EPA guide 700/B-92/001 February 1992, "A Guide to Performing Reinspections under the Asbestos Hazard Emergency Response Act (AHERA)." Procedures from this guide may be modified for appropriateness and applicability under changing standards. Any revisions to this guide will be used. One of the seven categories defined in the AHERA regulations will be assigned each friable surfacing, TSI, and miscellaneous ACM or PACM during inspections and reinspections:

As appropriate, the NASA Safety Office will perform air sampling in selected locations in conjunction with the building assessments under the following conditions:

Air sampling should be conducted in functional areas where the ACM or PACM has been deemed by an industrial hygienist or Certified Asbestos Consultant as "Damaged" or "Significantly Damaged" as defined by AHERA, or if deemed necessary by an industrial hygienist or certified asbestos consultant. Air-sampling results will aid in determining the actual airborne concentrations of asbestos or absence of asbestos. These samples can also show the airborne concentration of asbestos prior to abatement (as long as they are still representative of the sampled conditions).

30.11.4.1 Air-Sampling Procedure

All air samples during the quantitative assessment shall be collected per the specifications of NIOSH Sampling and Analytical Method 7400, PCM. Per the method, all fibers that meet a 3-to-1 aspect ratio and greater than 5 microns in length are counted to provide an airborne concentration in fibers per cubic centimeter (f/cc) of air. More sophisticated analytical techniques, such as transmission electron microscopy (TEM), are available that can differentiate types of asbestos and nonasbestos fibers and count extremely small fibers. The use of TEM will be specified at the judgment of the NASA Safety Office. Additionally, the NASA Safety Office will continue to review the health and safety literature and regulatory requirements and will make changes in analytical techniques as warranted. To ensure that the air samples are representative of occupant exposure conditions, air samples will be collected during normal workday activities in each selected area. The determination of normalcy will be based upon discussions with area personnel. Additionally, the area samplers will be placed as close as possible to breathing-zone height, i.e., five to six feet from the floor. Three samples per functional area should be collected unless physical limitations exist or if deemed unnecessary by an industrial hygienist or certified asbestos consultant.

30.11.4.2 Interpretation of Air-Monitoring Results

Air-sampling results from normally occupied areas, such as offices and laboratories, with airborne asbestos concentrations equal to or greater than 0.01 fiber /cc by PCM or 70 structures str/mm2 by TEM of air will be retested as soon as reasonably possible. If deemed appropriate by an industrial hygienist or by a certified asbestos consultant, the air-sampling results may be averaged. If the re-evaluation produces concentrations greater than 0.01 f/cc by PCM or 70 str/mm2 by TEM, the appropriate maintenance organization will be notified in order to determine the possible cause and begin necessary corrective action. When correction is completed, air monitoring will be repeated. All reasonable efforts will be made to control the airborne concentrations at less than 0.01 f/cc by PCM or 70 str/mm2 by TEM. If at anytime airborne concentrations meet or exceed 0.01 f/cc by PCM or 70 str/mm2 by TEM, occupants must be notified and removed from the area. Maintenance will be notified to respond or, if an abatement contractor is the potential source, the contractor will be notified along with his/her project manager and COTR.

Activities that involve the removal of TSI and surfacing ACM and PACM are considered Class I operations. This work is to be performed by asbestos abatement contractors meeting the requirements stated in 30.6.5 of this chapter, in accordance with CAL OSHA and BAAQMD regulations.

Activities that involve the removal of ACM that is not TSI or surfacing material are considered Class II operations. This includes, but is not limited to, the removal of asbestos-containing wallboard, floor tile and sheeting, roofing and siding shingles, and construction mastics. This work is to be performed by asbestos abatement contractors meeting the requirements stated in 30.6.5 of this chapter, in accordance with CAL OSHA and BAAQMD regulations.

Repair and maintenance operations where ACM (including thermal system insulation and surfacing material) is likely to be disturbed are considered Class III operations (must fit in one standard glove bag or waste container <60 inches square). All Class III asbestos work shall be conducted using engineering and work practice controls that minimize the exposure to employees who perform the asbestos work and to bystanders. Employers of workers are responsible for these controls and requirements, which include:

Maintenance and custodial activities during which employees contact ACM and/or PACM, and activities to clean up minimal waste and debris containing ACM and/or PACM will be considered Class IV asbestos work. (This work must not exceed the OSHA PEL or EL. If work is expected to release airborne asbestos fibers, which may cause the employee exposure in excess of the OSHA PEL or EL, work must be considered Class III work. The Safety Office shall determine this potential.) Employers of workers are responsible for these work practice and engineering controls for Class IV asbestos work, regardless of exposure, which include:

The following procedures must be used if asbestos is accidentally released:

30.12 Recordkeeping

All building asbestos management documents should be centrally located in the NASA Safety Office. Some of the documents include:

30.13 Procedures for Special Asbestos Activities

Special asbestos work activities include:

Before any asbestos-related work is conducted pursuant to and classified as an emergency demolition/renovation project, the NASA Safety Office must be notified and the work plan and schedule must be approved by the NASA Safety Office.

The OSHA General Industry Standard for asbestos impacts the N251 Automotive Repair Shop (Motorpool). OSHA standards require engineering and work practice controls during brake and clutch repair, inspection, disassembly, repair, and assembly operations. There are two methods that meet this requirement:

The brake and clutch inspection, disassembly, repair, and assembly operations shall be enclosed to cover and contain the clutch or brake assembly and to prevent the release of asbestos fibers into the worker's breathing zone. The enclosure shall be sealed tightly and horoughly inspected for leaks before work begins on brake and clutch inspection, disassembly, and repair and assembly. The enclosure shall be such that the worker can clearly see the operation and shall provide impermeable sleeves through which the worker can handle the brake and clutch inspection, disassembly, and repair and assembly. The ntegrity of the sleeves and ports shall be examined before work begins. A HEPA-filtered vacuum shall be utilized to maintain the enclosure under negative pressure throughout the operation. The HEPA vacuum shall be used first to loosen the asbestos-containing residue from the brake and clutch parts and then to evacuate the loosened asbestos-containing material in the vacuum filter. The vacuum's filter, when full, shall be first wet with a fine mist of water, then removed and placed immediately in an impermeable container, properly abeled, and disposed of in a hazardous waste container with a hazardous waste label. Any spills or release of asbestos-containing waste material from inside of the enclosure or vacuum hose or vacuum filter shall be immediately cleaned up and disposed of as hazardous material. Compressed air may not be used to remove asbestos fibers or particulates from the enclosure.

A catch basin shall be placed under the brake assembly and positioned to avoid splashes and spills. The reservoir shall contain water with an organic solvent or wetting agent. The flow of liquid shall be controlled so that the brake assembly is gently flooded to prevent the asbestos-containing brake dust from becoming airborne. The aqueous solution shall be allowed to flow between the brake drum and brake support before the drum is removed. After removing the brake drum, the wheel hub and back of the brake assembly shall be thoroughly wet to suppress dust. The brake support plate, brake shoes, and brake components used to attach the brake shoes shall be thoroughly washed before removing the old shoes. In systems that use filters, the filters, when full, shall be wet with a fine mist of water, then removed and placed immediately in an impermeable hazardous waste container with a hazardous waste label. Any remaining water should be wiped up with rags and disposed of in the same container as the filter. Any spills of asbestos-containing aqueous solution or any asbestos-containing waste material shall be cleaned up immediately and disposed of as hazardous material. The use of dry brushing during low-pressure/wet-cleaning operations is prohibited.

TA wire for the purpose of repairing electrical connections is classified as Class III asbestos-related work because this work is part of a maintenance and repair operation, and disturbance will occur as an adjunct to the repair and maintenance of the electrical system. The manipulation or inspection of TA wire in order to clean the connectors is not a construction activity, but the workers who inspect TA wire must have at least two hours of asbestos awareness training.

Prior to handling, removing, or cutting any electrical insulation, wiring, or conduit, the electrical wire shall be de-energized by turning off the power of the electrical equipment/devices that supply power to the service line. The electrical equipment/device shall be locked out and tagged pursuant to NASA and Federal/State regulations to prevent accidents, injuries, or electrocution of workers.

30.13.3.1 Method

Regardless of the type of activity, it is a regulatory requirement that all persons who engage in Class III asbestos-related work or the manipulation/inspection of TA wire adhere to the following:

30.13.3.2 Maintenance & Repair of TA Wire

30.13.3.3 TA Wire Reparation

If the TA wire is damaged and requires repair, the wire should be handled in a manner that will not release fibers into the environment. This may be accomplished by encapsulating the wire with another insulating material or enclosing the damaged wire with a suitable casing so that it no longer presents an electrical or asbestos hazard.

30.13.3.4 Repair of TA Wire Connectors

The repair of the TA wire connectors is limited to the minor manipulation of the wire to free the wire from the housing and facilitate the reparation of the connector either by replacement or repair. TA wire should remain intact during this operation and no waste shall be generated.

30.13.3.5 Inspection of TA Wire Connectors

Inspection of connectors should be accomplished in a manner that involves only minor manipulation of the wire.

Drilling holes into asbestos-containing material shall be limited to nonfriable materials such as transite siding, floor tiles, and sheetrock. Impermeable drop cloths must be placed under/around area(s) to be drilled, drilling must be performed through a wet sponge or disposable cup of shaving cream to prevent airborne fiber release. Upon project completion, the area must be cleaned using wet methods and/or HEPA vacuums if necessary. Notification must be provided to the Safety Office prior to any drilling operation that affects ACM/PACM. All persons conducting this work shall have, at a minimum, two-hour asbestos awareness training.
