Asbestos Management Plan
Asbestos-containing materials (ACM) have been used widely in the construction industry. While the use of ACM in new building systems has ceased for most major applications, the presence of ACM in older building systems is still widespread. On this campus, ACM is still present in numerous buildings in the form of pipe insulation, sprayed-on fireproofing, sprayed-on acoustic insulation, and flooring materials. In most cases, this ACM does not pose a health hazard if left undisturbed. Nevertheless, activities that have the potential to disturb ACM must be carefully managed to prevent fibers from becoming airborne and creating an inhalation hazard.
The purpose of this plan is to describe a program for controlling exposure to asbestos in campus buildings. The principal elements of this program involve requirements and responsibilities for surveys, training and certification of workers, employee notifications, proper work procedures for activities that have the potential to disturb ACM, and proper disposal of asbestos wastes.
Asbestos-Containing Material (ACM) - any material containing more than one percent asbestos.
Asbestos-Containing Construction Material (ACCM) - any manufactured construction material that contains more than one tenth of one percent asbestos by weight.
Presumed Asbestos-Containing Material (PACM) — thermal system insulation and surfacing material found in buildings constructed no later than 1980. These materials are assumed to contain asbestos unless data rebuts the classification.
Friable Asbestos Material — any material containing more than one percent asbestos that, when dry, can be crumbled, pulverized or reduced to a powder by hand pressure.
Non-Friable Asbestos-Containing Material — any material containing more than one percent asbestos, that, when dry, cannot be crumbled, pulverized or reduced to a powder by hand pressure.
Category I Non-Friable Asbestos-Containing Material — asbestos-containing packings, gaskets, resilient floor covering and asphalt roofing products containing more than one percent asbestos, that, when dry, cannot be crumbled, pulverized or reduced to a powder by hand pressure.
Category II Non-Friable Asbestos-Containing Material — any material, excluding Category I Non-Friable Asbestos-Containing Material, containing more than one percent asbestos that, when dry, cannot be crumbled, pulverized or reduced to powder by hand pressure.
Regulated Asbestos-Containing Material (RACM) — friable asbestos material; Category I Non-Friable Asbestos-Containing Material that has become friable or will be subjected to sanding, grinding, cutting or abrading; and Category II Non-Friable Asbestos-Containing Material that has a high probability of becoming crumbled, pulverized or reduced to a powder by the forces expected to act on the material in the course of demolition or renovation operations.
These definitions describe the types of asbestos-containing materials that are regulated under California Code of Regulations, Title 8, Sections 341.6 and 1529, and the National Emission Standard for Asbestos as implemented by the Air Pollution Control District, County of San Diego.

K. Demolition and Renovation
Demolition and renovation operations that involve the presence of RACM in excess of specified amounts must be conducted in accordance with the notification requirements and procedures for asbestos emission control of the National Emission Standard for Asbestos (as implemented by APCD Rule 361.145).
Asbestos Containing Materials (ACM) are prevalent in buildings throughout the San Diego State University Campus. Typically, ACM is found in fireproofing, acoustical and decorative ceiling and wall plasters, and thermal pipe and tank insulation. ACM may also be found in such materials as plaster walls, ceiling and floor tiles, roof felts, chemical hoods, oven gaskets, automobile brakes and clutches, and many other items. Because of the significant amount of asbestos (both friable and non-friable) within SDSU buildings, it is imperative that a coordinated program be in place for identifying ACM, notifying building occupants of its presence and location, and developing procedures to minimize disturbance of asbestos and possible exposure. This section describes the San Diego State University program for identifying and characterizing the condition of asbestos in buildings.
II. System-wide Survey (Historical)
Two system wide asbestos surveys were performed for the CSU System. Baker Consultants performed the initial survey in 1985, and a follow-up survey was performed in 1987-88 by the Dynamac Corporation. The scope of each survey was as follows:
- Locate all suspected friable asbestos containing building materials (ACBM).
- Sample all suspected materials and analyze them using Polarized Light Microscopy (PLM).
- Characterize the condition of the asbestos based upon a modified EPA algorithm developed by the consultants.
- Assign a hazard ranking category and number to each sample location that tested positive for asbestos.
- Develop abatement cost estimates for all asbestos locations that were categorized as C, D, and F by Dynamac or 4, 5, 6, and 7 by Baker Consultants.
- Cost estimates included asbestos abatement, development of abatement specifications, project monitoring, and, in the Dynamac report, restoration. However, restoration costs were not included for all locations that were needed, and Baker consultants did not include any restoration costs in their reports.
- Develop guidelines for an asbestos operation and maintenance program.
III. Campus Inspection and Surveillance Programs
A. Periodic Surveillance of Known Locations of ACM
In order to prevent exposure of building occupants to asbestos fibers, periodic surveillance of known locations of friable and non-friable ACM will be performed to determine if damage or deterioration has occurred. Facilities Services personnel will conduct the annual surveillance and maintain the associated records. If there is a need to perform additional sampling and analysis of suspect building materials, the Asbestos Coordinator in EH&S should be contacted (extension 46778).
B. Inspection of Previously Unidentified ACM
Neither one of the system-wide asbestos surveys sampled for and confirmed the presence of non-friable ACM such as plaster walls, vinyl asbestos floor tiles, ceiling tiles, and roofing felts. Because of the potential for employee exposure to asbestos fibers when these materials are disturbed (e.g., penetrating walls, removing floor & ceiling tiles), a procedure shall be used to ensure that building materials are sampled and analyzed prior to the start of construction or maintenance activities. Cal/ OSHA requires that certain building materials be sampled for the presence of asbestos, or assumed to be ACM. Additionally, the NESHAP requires that RACM (regulated asbestos containing material) must be removed prior to demolition or renovation.
1. Work Order Review
Facilities Services must route work orders through EH&S. EH&S will assess the potential for asbestos hazards. This may involve the sampling and analysis of suspected asbestos containing building materials. The proposed work shall not commence until EH&S has completed the assessment and approved the work order. The work order is then sent forward with comments relating to asbestos control.
2. Bulk Materials Sampling & Analysis
AHERA sampling techniques shall be utilized throughout the sampling survey (reference EPA “Pink Book”). Asbestos sampling shall be performed only by EH&S or Facilities Services staff who are trained in this process. The samples are analyzed by an EPA accredited laboratory. A copy of the laboratory sample results shall be sent by EH&S to the Project Manager. The results are also entered into the Campus Asbestos Material Location File.
(a) Asbestos bulk samples shall be collected by, or under the direction of, a person who has completed an asbestos building inspector course and who is currently certified.
(b) The immediate area shall be secured so that building occupants are not present. Preferably, sampling should be performed outside of normal business hours.
(c) An appropriate respirator equipped with HEPA filters shall be donned prior to collecting samples.
(d) Asbestos containing material should not be sampled dry. Wet the surface of the sample area with a surfactant (typically 50% polyethylene-glycol) or water. For core sampling, a wet sponge can be placed over the sampled area and the core will be run through the sponge into the suspected ACM. Penetrate the suspected material completely with a sharp object such as a coring tool, blade or knife and remove a small section of the suspect material. Minimum sampling numbers:
- Area of the homogeneous suspect ACM <1000 linear or square feet (3) three bulk samples shall be collected.
- Area of homogeneous suspect ACM is at least 1000 linear or square feet, but <5000 linear or square feet, at least (5) bulk samples shall be collected.
- Area of homogeneous suspect ACM is >5000 linear or square feet (7) seven bulk samples shall be collected from each area.
(e) Place the sample in a sealed container.
(f) Patch or repair the material where the sample was removed.
(g) Label the sealed container and record the following information:
- Location of sample (a graphic depiction of sample location should be included for demolition records)
- Type of material (e.g., plaster wall, thermal system insulation)
- Name or initials of individual taking sample
- Laboratory that will be analyzing sample and phone number
- Sample result (to be filled in after analysis)
- Sample number - unique to the location and/or sample
(h) Submit the sample to an EPA approved laboratory for analysis.
(i) Depending upon the quantifying limit needed, the sample should be analyzed by either of two methods:
- Polarized Light Microscopy (PLM) for quantifying limits equal to or exceeding 0.1% asbestos by weight.
- Transmission Election Microscopy (TEM) if a detection limit below 0.1% asbestos by weight is needed.
Note: Fine dust samples from operations like brake rebuilding should be analyzed using TEM.
3. Quality Assurance (QA)
Appropriate analytical Quality Assurance (QA) procedures must be established and followed by the analytical laboratory. It is the responsibility of EH&S to ensure that appropriate QA requirements are provided to Purchasing and Contracts for inclusion in bid specifications.
All sample results are incorporated into the Master Data Base “Asbestos Locations Within SDSU Buildings.” This list is communicated to building occupants in accordance with the notification requirements of Section IV.B of the Asbestos Management Plan.
The master ACM Sample list is maintained by the Asbestos Coordinator and is available in the EH&S Office during normal work hours (8 a.m. to 4:30 p.m.).
This Standard Operating Procedure (SOP) describes control measures for performing Class III and Class IV asbestos work pursuant to 8 CCR 1529. ACM is present in campus structures in a wide variety of forms. This SOP addresses several types of removal operations as separate items. The control measures of this SOP are “good work practices” in addition to the applicable requirements described in the parent procedure, the Asbestos Management Plan.
The four EPA classifications for asbestos work are:
- Class I Asbestos Work: Removal of TSI or Surfacing ACM or PACM.
- Class II Asbestos Work: Removal of any other ACM/ PACM that is not TSI or surfacing material.
- Class III Asbestos Work: Repair and maintenance operations where ACM/ PACM is likely to be disturbed.
- Class IV Asbestos Work: Maintenance and custodial activities where employees contact ACM/ PACM and activities to clean up debris. Custodial personnel do not perform asbestos clean up.
II. Friable ACM
Many of the control measures for ACM removal depend on whether or not the material is considered “friable.” The determination of friability is, therefore, a critical step in developing the strategy of ACM removal. If a suspect material is, when dry, capable of being crumbled, pulverized or reduced to a powder by hand pressure, and if the material contains asbestos fibers in excess of 1%, it is considered friable ACM and must be treated as a hazardous material.
B. GENERAL PROTECTION REQUIREMENTS
1. Primary consideration will be given to the protection of building occupants and asbestos workers. The following steps shall be taken for any work that may involve disturbing friable ACM:
(a) Restrict entry to the area for all personnel other than those needed to perform the work.
(b) Post signs to communicate the hazard and to prevent entry by unauthorized personnel.
(c) Shut off or temporarily modify the air handling system, and restrict other sources of air movement.
(d) Use work practices (e.g., negative pressure enclosure or glove bag operations as described below) which are designed to prevent the spread of any fibers released by the work being performed.
2. All personnel who are likely to disturb ACM or who may be exposed above the permissible exposure limits (PELs) must be properly trained and protected. As a minimum, this protection entails:
(a) 4-day EPA approved course for asbestos abatement workers and annual 8-hour refresher training.
(b) Medical surveillance.
(c) Initial fitting for a respirator.
(d) Refitting for a respirator annually or whenever a significant change in the face to mask fit is detected.
(e) Asbestos exposure monitoring.
3. All personnel who contact ACM must receive 2-hour asbestos awareness training.
EH&S must be notified of projects that are likely to cause the disturbance of ACM. Contact the Asbestos Program Manager at 619-594-6778. The Asbestos Program Manager will determine the monitoring, notification, and other protection measures for the project in question. Because most asbestos work will require exposure monitoring, and the Ni-Cad batteries on the samplers take approximately 24 hours to recharge, it is desirable for EH&S to receive at least 24-hour notice of asbestos work.
D. Exposure Monitoring
EH&S may conduct exposure monitoring during asbestos work and clearance monitoring at the completion of asbestos work. Additionally, EH&S may collect baseline air samples from the work site prior to asbestos work. If the potential exists for the release of fibers to the extent that the PELs may be reached, EH&S will establish a full personnel protection and monitoring program for the project in question. At present the PELs for asbestos are 0.1 fibers per cubic centimeter of air as an 8-hour time weighted average and 1.0 fibers per cubic centimeter of air as averaged over a 30-minute period. Personnel monitoring will be performed during the asbestos work to demonstrate that breathing zone concentrations were maintained below the PELs.
E. Glove Bag Operations
The “Glove Bag” method provides a safe means for removal of small amounts of ACM on pipes and in small surface areas. The following procedures should be followed when the glove bag method is used to remove ACM.
1. Utilize personal protective clothing, such as the “Tyvek” suits, gloves and a respirator that has been provided and fitted by EH&S.
2. Isolate the area where the ACM is located. Place barrier tape across the doorways and at least 20 feet around the area where the ACM is located.
3. Place 6-mil plastic sheeting under the glove bag set-up.
4. Ensure that all ventilation units that service the area where the ACM is located are shut off and tagged out.
5. Don the respirator and perform a “negative” and “positive” pressure test. If you are unable to obtain a successful pressure test on the respirator, see your supervisor. DO NOT PROCEED WITH ACM WORK WITHOUT A PROPER RESPIRATOR FIT.
6. Determine the area where the ACM is to be removed. Place the glove bag next to the pipe and measure how much area will need to be removed. Tape the area on the pipe to delineate the area from which ACM will be removed. Tape the bottom seam of the glove bag. Slit the side seams of the glove bag to fit the pipe diameter. Seal the sides and top seam with tape after placing the necessary tools into the bag. Cut a small hole in the bag in the same area where the wetting wand will be placed during the actual ACM removal stage. Fill the bag with smoke from the smoke tube and seal the hole. Gently squeeze the bag and observe any leaking areas. Tape the leaking areas to achieve an airtight seal. If the pipe lagging is badly damaged or deteriorated the ACM may require wetting or taping to prevent a further release of fibers.
7. Most glove bags will melt or deteriorate at temperatures of 130o F or more. For steam or hot water lines, therefore, it may be necessary to shut off the pipe valve to ensure that the bag does not deteriorate or that the worker does not receive burns.
8. Wet the ACM completely prior to removal and keep the ACM wet during the removal process. Use amended water in an airless spray pump. A hand spray bottle may also be used. The hole created for the spray wand can also be used for the HEPA vacuum nozzle.
9. All visible ACM must be removed from the pipe using a hard brush and amended water while the glove bag is still in place. Wet wipe and spray the pipe with encapsulant prior to removing the glove bag. Special attention must be given to exposed ends of pipe lagging.
10. Place all tools into one of the armholes and pull inside out. Tape and cut the arm from the glove bag and remove the tools while they are still sealed in the arm or glove.
11. Wet the inside of the bag with amended water and place the vacuum nozzle into the bag to cause the bag to collapse. Unseal the bag and remove from the pipe. Place the bag into another 6-mil asbestos waste bag and seal tightly. This bag must be marked as an ASBESTOS DISPOSAL BAG with the proper Danger and warning labels:
Contains Asbestos Fibers
Avoid Creating Dust
Cancer and Lung Disease Hazard
12. The exposed section of pipe will now be closed and sealed with a non-asbestos material.
13. If the remaining pipe contains ACM, the pipe must be labeled “DANGER ASBESTOS MATERIAL.”
III. NON-FRIABLE ACM
Many applications of ACM are not friable, but nevertheless can pose a health hazard if not managed properly. The application of non-friable ACM most commonly encountered at SDSU is a flooring material known as vinyl asbestos tile (VAT). Other non-friable forms may include roofing felt, underground water lines, laboratory benchtops, etc. Although the following requirements relate specifically to VAT, the principles are generally applicable to other asbestos work involving non-friable ACM.
- VINYL ASBESTOS TILE (VAT)
Most vinyl asbestos floor tiles on campus are of the 9” x 9” tile size. The floor tiles are held in place by an adhesive (mastic) that may also contain asbestos. If there is any doubt whether a specific area of floor tile or mastic contains asbestos, call EH&S at 619-594-6778 to arrange for positive identification. (Note: Most flooring material in buildings constructed prior to the mid-1970s should be considered as suspect ACM.)
1. Because there is a possibility that during a VAT procedure employees may become exposed to asbestos fibers in excess of the PELs, the notification procedure for VAT jobs is the same as that prescribed for the glove bag operations.
2. All removal of VAT should be performed under wet conditions.
3. The tiles should be removed with the least amount of breakage of the tiles.
4. All vacuuming MUST be performed with a HEPA-filtered vacuum only.
5. Mopping or wet wiping may be used to wet-clean debris (which must be assumed to contain asbestos) from the floor. The mop or wipe is to be moved in one direction for no more than six feet, turned over, and the action is repeated for six more feet in the same direction. At the end of the two passes the mop or wipe is to be rinsed in a water bucket. These actions may be repeated, utilizing the same bucket of water until the water becomes visible soiled.
6. Mop heads and wipes are to be used for one project only. They are to be disposed of by placing them into an asbestos disposal bag at the end of the project. Asbestos-containing rinse water may also require controlled disposal. Contact EH&S for guidance on disposal of all asbestos-contaminated wastes.
EH&S will maintain a record of all bulk material and air sampling results performed in support of friable or non-friable asbestos work. Facilities Services personnel are responsible for providing EH&S with a copy of the “Competent Person Designation and Duties Checklist” for its records.
I. Summary and Purpose
This section describes SDSU’s Operations and Maintenance (O&M) Program. The program applies to asbestos-containing materials (ACM) that are managed “in place,” as opposed to management by removal. The purpose of the O&M Program is to define a course of action aimed at safeguarding the health of SDSU employees, students, and visitors by maintaining ACM in a stable condition, thereby preventing deterioration or damage that can result in the release of asbestos fibers.
Specifically, the four directives that have been established to accomplish this objective are:
A. Monitor the condition of ACM on campus
B. Maintain ACM in good condition
C. Ensure proper cleanup of releases of asbestos fibers
D. Prevent further release of fibers
The O&M Program is a major component of the overall SDSU Asbestos Management Program. It provides a system of surveillance, control, and work practices that applies specifically to O&M activities. These procedures are used in conjunction with other elements of the Asbestos Management Program, such as notification, training, and record keeping.
II. Program Components
SDSU is responsible for notifying employees, contractors and other building occupants of the location of ACM. Notification to some regulatory agencies is also required. The notification program is detailed in Section IV.B and Attachment D of the Asbestos Management Plan.
Facilities Services personnel that are AHERA Management Planner certified will perform regular surveillance to note, assess, and document any changes in the condition of ACM. This includes a visual and tactile surveillance of known ACM at least annually. EH&S will sample dust found in areas around ACM, and will also perform supplemental periodic air monitoring based on O&M reports, assessed priorities, and in the event of fiber release episodes. Any debris noted during the surveillance will be cleaned up immediately.
C. Work Control
Activities that may disturb ACM must be coordinated with EH&S. The Facilities Services Work Control Center will compare incoming work orders with the asbestos locations list published by EH&S. Work orders that have the potential for disturbing ACM due to proximity to the material or the nature of work performed will be sent to EH&S for evaluation. Facilities Services personnel involved in completing work orders will receive 2-hour asbestos training as described in Attachment D of the Asbestos Management Plan. EH&S will perform necessary sampling of suspect ACM as described in Attachment A.
D. Work Practices
Work Practices for custodial, maintenance, and trades workers will be tailored to prevent the release of fibers based on the nature of the work to be performed. Four levels of O&M work practices are involved:
1. Worker protection programs. These include SDSU’s Respiratory Protection Program, the use of appropriate personal protective equipment, personal and area air sampling administered by EH&S, and most importantly, administrative and engineering controls where feasible. Administrative and engineering controls are discussed in Section II of the Asbestos Management Plan. (A copy of the EPA pamphlet - Asbestos in Buildings, Guidance for Service and Maintenance Personnel is available.)
2. Basic O&M procedures. General glove bag procedures are described in Attachment B. Additional work practices such as wet wiping, area isolation, HEPA vacuuming, and use of personal protective equipment are to be employed whenever feasible. Specific O&M procedures as they relate to other applications of ACM are described in Attachment B of the Asbestos Management Plan.
3. Special O&M cleaning techniques. Special cleaning practices are required to decontaminate areas that contain surfacing or insulation, especially if the material is damaged or deteriorated. Proper O&M cleaning involves the use of wet cleaning or wet-wiping practices to pick up asbestos fibers. The use of a vacuum cleaner equipped with a high efficiency particulate air (HEPA) filter is preferable to wet cleaning in some instances, especially where significant amounts of asbestos debris exist. Ordinary vacuum cleaners shall not be used for O&M cleaning. Dry sweeping or dusting can result in suspension of fibers and should not be used.
4. Response to asbestos fiber release episodes. Accidental fiber releases involving greater than 3 square or linear feet of ACM are to be managed by isolating the site, erecting barriers, shutting off ventilation systems, notifying EH&S and other affected personnel, and clean-up under the guidance of EH&S and the procedures in this document. EH&S will coordinate clearance air sampling and notifying government agencies, if required. Minor releases (less than 3 square or linear feet of ACM) may be handled using wet methods, HEPA vacuums, and notifications and other guidance coordinated by EH&S.
III. Waste Management
O&M activities often result in the generation of asbestos-containing waste materials. All waste materials that are known or suspected to contain asbestos shall be handled in accordance with Section IV.H of the Asbestos Management Plan.
Training requirements related to O&M are described in Section IV.E and Attachment D of the Asbestos Management Plan.
V. Recording Keeping
Record keeping requirements related to O&M are described in Section IV.J of the Asbestos Management Plan.
The purpose of this procedure is to describe the asbestos awareness training program. This training is administered by individuals who are considered “Asbestos Competent Persons” as defined in the AHERA legislation.

PART IV — HEALTH EFFECTS OF ASBESTOS
A. Respiratory Tract
1. Vast majority of asbestos-related disease is respiratory
2. Normal function of respiratory system
(a) Review Structures (refer to overhead)
- Bronchi — carry oxygen to lungs
- Alveoli — where gas exchange occurs with blood
- Pleura — surrounds lungs and pleural cavity; coated with liquid to allow lungs to easily slip by chest wall during expansion and contraction.
(b) Filtration mechanism for inhaled contaminants — review functions
- Impaction in nose & mouth
- Mucous lined airways
- Ciliated cells in airways
- Macrophages in alveolar region
3. Asbestoses — Characterized by fibrotic scarring of the lung
(a) Reduces lung capacity — lungs cannot expand.
(b) Latency — fifteen to thirty years.
(c) Clear dose/response relationship: The greater the asbestos exposure, the greater the potential for injury.
(d) All types of asbestos have been linked to asbestoses.
(e) The proposed mechanism for asbestoses development is as follows:
- A few fibers are not filtered out in the upper airways
- The fibers reach the terminal air sacs (alveoli)
- Macrophages in the alveolar region
- Asbestos is inert, therefore, it cannot be broken down
- A coating is subsequently deposited on fiber
- Scar tissue forms around the fiber
- Increased scarring throughout the lung results in asbestoses
(a) A cancer of the pleura.
(b) The abdominal cavity lining can also be affected.
(c) Latency of thirty to forty years.
(d) Can be caused by very low exposure: not directly related to dose (Steve McQueen wore an asbestos suit while race car driving. It is thought that this limited exposure may have caused his illness.)
(e) Rapidly spreading and always fatal.
5. Lung cancer
(a) Asbestos related tumors are usually found in the lower lobes.
(b) Most cancers found are glandular in nature which is rarely the case in non-asbestos related tumors.
(c) Latency — twenty plus years.
(d) Dose/response relationship has been established — although no “safe” level has yet been determined.
6. Smoking and lung cancer
(a) The risk of developing lung cancer among asbestos workers increases drastically if workers also smoke (use attached overhead)
- Set the general population equal to 1.
- Asbestos workers who do not smoke are five times more likely to develop lung cancer than the general public.
- People who smoke but do not work with asbestos are ten times as likely to develop lung cancer than the general public.
- People who smoke and work with asbestos are fifty to ninety times as likely to develop cancer.
- Obviously this incidence rate is due to more than just adding up factors. The term for such relationships where risk factors increase in multiples is “synergistic.”
(b) Two proposed mechanisms for asbestos-related lung cancer development associated with cigarette smoking:
- Smoke is inhaled and ciliated cells along the airways are temporarily paralyzed.
- The body can no longer defend against unwanted dust.
- The offending asbestos particles cannot be cleared. This allows them more time to work downward toward the alveolar region or embed into tissues.
- Asbestos is inhaled and trapped in fibrotic areas.
- Normal mechanical clearance(mucous and cilia) is disrupted.
- Tobacco smoke subsequently inhaled is cleared less efficiently, therefore, carcinogens in the smoke remain in contact.
(c) Asbestos fibers preferentially settle in peripheral regions of lower lobes.
(d) Both of the proposed mechanisms result in the same disease; it is likely that a combination of factors elicits the observed synergistic response.
B. Non-respiratory Asbestos-related Conditions
1. Asbestos “warts:”
(a) Fiber bundles embed in tissue; usually hands.
(b) Gloves should be worn when handling asbestos.
2. Colon, esophageal, or stomach cancer:
(a) May be asbestos-related.
(b) Fibers can work their way through soft tissues to adjacent structures and embed.
(c) Fibers entering the mouth can be swallowed thereby entering the digestive tract.
(d) Asbestos physicals generally include a rectal exam.
(e) Poor Hygiene, leaving food out in contaminated areas, and carelessness all can contribute to ingestion of asbestos.
C. Symptoms and Effects of Asbestos Exposure
1. Acute exposure: no immediate symptoms or effects
2. Chronic Exposure:
(a) Shortness of breath
(b) Dry cough
(c) Loss of appetite
(d) Weight loss
(f) Lung cancer
(h) Intestinal tract cancers
By the time chronic effects manifest themselves, disease is most often irreversible.
PART V - LOCATION OF ASBESTOS ON CAMPUS
A. Distribute list of areas known to contain ACM and discuss.
B. Discuss areas already abated.
C. Ask if attendees are aware of any areas known to contain asbestos which are not on Notification List.
D. Generally discuss campus identification \ labeling protocol for areas containing asbestos.
PART VI — DISCUSSION OF CONDITIONS OF ASBESTOS
A. Define friable and the significance of material found in this condition.
B. What causes asbestos materials to become damaged and friable?
1. Some material is applied in a friable state:
(b) Blown-on acoustical insulation
(Ask for more examples)
2. Physical disturbance:
(a) Basketballs thrown up at asbestos ceilings.
(b) Broom handles scraped along corridor ceilings.
(c) Ceiling tiles or other debris falling on pipes during renovation.
(d) Pipe work requiring breaking seal around lagging.
3. Deterioration or delamination:
(a) Water leaks from ceiling causes ceiling asbestos coating to pull away (delaminate) from base material.
(b) Steam leak
4. How to recognize damage:
(a) Ceiling water stains
(b) Visibly disturbed lagging
(c) Suspicious debris
PART VII - CAMPUS ASBESTOS MANAGEMENT PROGRAM
A. General program for control of asbestos.
B. Who is the campus asbestos coordinator?
C. What is small scale (glove bag) removal procedure, and how are Unit 6 personnel involved?
D. Who performs full-scale removal on campus? How are contractors selected?
E. What should be done in the event of an asbestos emergency?
F. What should be done if questionable material not previously classified is discovered?
PART VIII - REGULATIONS
A. Cal-OSHA Asbestos Regulations (see overhead):
- PEL = 0.1 fibers/cc
- Excursion limit = 1 fibers/cc
B. AB 3713 and AB 1564 (provided as handouts):
- Notification of employees
C. Asbestos Hazard Emergency Response Act (AHERA):
- Regulates K-12 schools only; not private sector or post 12 schools.
- Outlines protocol for setting up asbestos program requirements, and for training of each party involved in the response effort;specified two-hour awareness training.
- CSU does not fall under these regulations, but rather looks to them for guidance.
