INTRO DUCTION: Per your request, on October 19, 1989 A. F. Meyer and Associates. Inc. (AFMA) performed a limited study to determine asbestos fiber release, if any, from routine buffing and stripping of vinyl asbestos floor tiles. The study was performed by John B. Love and Reynolds B. Renshaw in classroom 18 at the Sligo Middle School in Montgomery County, Maryland. Southern Insulation, a licensed asbestos abatement firm performed the buffing and stripping operations. Samples of the 9' x 9` vinyl floor tiles Indicated they contained 5% chrysotile asbestos in the tiles themselves and 10% chrysotile , asbestos in th e mastic used to adhere the tiles to the concrete floor of the school. This study is very limited and must not be construed as being all inclusive as to asbestos exposures encountered by custodial and maintenance staff, students, teachers, and the general public in schools generated from routine buffing and stripping of asbestos-containing floor ties. It was intended to provide an indication of whether or not there Is a potential to release asbestos fibers from the tiles during buffing or stripping. It was also intended to provide a foundation for further investigation if warranted based on its outcome. 2. PROCEDURES USED: The approximate size of classroom 18 was 30 feet by 28 feet (840 square feet). This part of the school was unoccupied at the time of the study. Prior to the buffing and stripping operations, the classroom was totally isolated from the rest of the school by constructing a containment consisting of tw o layers of 6 mil plastic sheeting on the walls and a three-stage decontamination facility connected to the area. A high efficiency particulate air (HEPA) exhaust unit was placed inside the dassroom. The exhaust unit was operated at a low setting so as not to provide rapid air exchange and filtration. The purpose of the unit was to create a slight negative pressure differential relative to adjacent areas of the school so fiber release would not occur outside the contained dassroom. After total isolation of the area and prior to performing the floor maintenance, ail surfaces within the dassroom were pre-deaned via wet methods using amended water. All floor maintenance supplies (l.e. buffing/stripper solutions and pads) were provided by Channel 4 and Montgomery County janitorial staff. Buffing and stripping procedures were discussed at length with maintenance staff prior to conducting the study. For the purposes of this study the following buffing and stripping methods were employed: M ETHO D 1 - BUFFING Buff with standard red buffing pad and standard buffing solution. (Duration - approximately 45 minutes). M ETHO D 2 - STRIPPING Strip floor using standard stripping mixture mopped on and standard black stripping pad. Mop with dean water twice afterwards. (Duration - approximately 70 minutes). M ETHO D 3 - STRIPPING Strip floor using a fine mist spray of stripper solution and standard black stripping pad. Mop with dean water twice afterwards. (Duration approximately 70 minutes). During all floor maintenance operations, persons performing the work wore full-body protective (Tyvek) suits and full-face respirators equipped with filters designed for protection against airborne asbestos dust/fibers. Workers and survey persons, using appropriate procedures, entered and exited the work area through the decontamination facility. Once all buffing and stripping operations were complete and the study concluded, the floor was mopped and waxed to ensure any remaining dust or fibers would not become airborne once the containment was dismantled and the area re-occupied. 1 A. F. MEYER AND ASSOCIATES, INC. 3. SAMPLING PROTOCOL AND ANALYTICAL METHODS: Bulk samples were collected from the water used during pre-cleaning, the water and stripper mix m opped up after the final stripping method, the buffing (red) and stripping (black) pads used, and from the residual dust remaining on the tiles after the final stripping and mopping method. General area air samples were collected in the classroom prior to the buffing and stripping work, during each method used, and under aggressive sampling conditions using a leaf blower after the final stripping and mopping method and before re-waxing the floor. Two samples were collected during each sampling period, one located approximately two feet from the floor and the other approximating breathing zone level, or five feet above the floor. One eight-hour air sample was collected from the workers' breathing zone. Two general area air samples were collected outside the contained classroom at the entrance to the decontamination facility. General air samples were collected with high volume line operated sampling pumps at a flow rate of 8.5 - 8.7 liters per minute (Ipm). The worker breathing zone air sample was collected using a battery operated personal sampling pump at a flow rate of 2.4 Ipm. All sampling pumps were calibrated before and after each sampling period. Bulk samples were analyzed using Polarized Light Microscopy (PLM) and Transmission Electron Microscopy (TEM). Air samples obtained from inside the classroom prior to, during, and after the buffing and stripping operations were collected on 0.45 micron pore size mixed cellulose ester membrane filters with 50 mm non-conductive extension cowls. These samples were analyzed using Transmission Electron M icroscopy (TEM) . The outside general area and worker breathing zone air samples were collected on 0.8 micron pore size mixed cellulose ester membrane filters with 50 mm non-conductive extension cowls. These samples were analyzed using Phase Contrast Microscopy (PCM). The general area samples outside the contained classroom were also analyzed by TEM. (For specific methods of analyses used please see the attached tables). 4. LIM ITS FOR AIRBORNE ASBESTOS: a. Except for abatement activities, there are no exposure standards for non-occu pattonal settings. b. There are standards for general air quality after completion of an abatement or response action and before re-occupation of the areas involved. These standards are based on the analysis of a minimum of five samples collected within the work area after abatement Is complete. Samples analyzed using phase contrast microscopy must all demonstrate concentrations less than 0.01 fibers per cubic centimeter (f/cc). Samples analyzed using Transmission Electron Microscopy (TEM) must have an average of less than 70 structures per square millimeter or not be statistically significantly different (higher) than 5 samples collected from outside the contained work area. c. The EPA's Worker Protection Rule 40 CFR Part 76 3.121 has been extended to employees of local education agencies who perform operations, maintenance, and repair (O & M) activities involving asbestos-containing material. Under the n ie , the permissible exposure limit for asbestos based on an eight-hour time weighted average is 02 fibers per cubic centimeter (f/c c ) with an action level of 0.1 f/cc. 5. RESULTS OF SAM PLING : a. Analysis results of the sample collected from the water used during pre-deaning Indicated asbestos was present Results of the sample collected from the stripper and water mix after the stripping operations showed dose to two times that of the water used during predeaning. In both instances, asbestos structures detected were ail less than 10 micrometers In length. Consequently, the reported concentration of structures greater than 10 micrometers In both samples was less than 122.7 million structures per liter (MILL STR/L). b. Analysis results of the bulk sample collected from the residue on the buffing (red) pad indicated a trace of chrysotile asbestos. 9 A. F. MEYER AND ASSOCIATES, INC. c. Analysis results of the bulk sample collected from the residue on the stripping (black) pad indicated 1% chrysotile asbestos. d. Analysis results of the bulk sample collected from the remaining residue on the floors after the final stripping method indicated a trace of chrysotile asbestos. e. Results of the air sample collected from the workers breathing zone yielded a concentration of 0.013 fibers per cubic centimeter as an eight-hour time weighted average. f. General area air samples collected inside the contained dassroom before any buffing or stripping operations were performed (background) indicated airborne fiber densities of 30.5 and 45.8 structures per mm* (0.01 and 0.015 structures per cc). g. General area air samples collected Inside the work area during buffing operations performed showed airborne fiber densities of 15.3 and 45.8 structures per mm* (<0.01 and 0.015 structures per cc). h. General area air samples collected within the contained dassroom during the first stripping operation (Method #2) showed airborne fiber densities of 91.6 and 229.0 structures per mm* (0.029 and 0.072 structures per cc). i. Genera/ area air samples collected within the contained dassroom during the second stripping operation (Method #3} yielded airborne fiber densities of 236,167.6 and 276,316.1 structures per mm5 (77.5 and 89.2 structures per cc). It should be noted that these samples couid not be analyzed by standard TEM analysis because of excessive loading on the filters. The samples were prepared by low-temperature plasma ashing and aqueous redeposition due to overloading of the filters. Complex asbestos structures consisting of multiple fibers may have disaggregated during sample preparation. Consequently, asbestos structure counts may be biased high. j. General area air samples collected using aggressive sampling techniques after the final stripping operation indicated airborne fiber densities of 137.4 and 183.2 structures per mm* (0.045 and 0.06 structures per cc). k. All asbestos sample analysis results are outlined in the attached Tables 1 and 2. 6. C O N C L U S IO N S : a. Again, this study has limitations and cannot be used to definitively quantify general occupant and maintenance staff exposure levels to asbestos from floor tile maintenance activities In ail situations. It applies only to conditions encountered and techniques used at the time of sampling. b. Concentrations found in the workers breathing zone during this study did not exceed the existing permissible exposure limit nor the action level outlined in the EPA's Worker Protection Rule. The sampling and analytical method required for worker exposure monitoring detects all fibers with characteristics of asbestos fibers and which are greaier than 5 microns in length. Levels found however, do warrant consideration when assessing overall asbestos exposures to employees involved in routine operations, maintenance and repair activities. c. Airborne asbestos fiber densities or concentrations found in the general air within classroom 18 prior to the buffing and stripping operations did not exceed filter background levels (70 s/mm*) when analyzed using TEM. -d. General area air samples collected during buffing operations did not exceed filter background levels 'when analyzed using TEM. A. F. MEYER AND ASSOCIATES, INC. e. General area air samples collected during stripping operations and under aggressive sampling techniques after all stripping was done did significantly exceed filter background levels when analyzed using TEM. It appears that airborne asbestos structure densities started to increase dunng the first stripping method (stripping mixture mopped on and using standard black stripping pad) and elevated tremendously during the second stripping method (fine mist spray of stripper solution and using standard black stripping pad). Aggressive sampling conducted after the second or final stripping method and after the floor was mopped showed that airborne asbestos structure densities returned to levels near those experienced during the first stripping method. This leads us to believe that stripping asbestos-containing floor ties using semi-wet techniques has a far greater potential for releasing airborne asbestos than stripping methods employing wet or very wet methods. It should be noted that of the general area air samples collected Inside the classroom during these operations, nearly all asbestos structures found were less than 5 microns in length. f. Based on the air sampling, it is the opinion of this study that asbestos fibers or structures were released from the floor tiles and became airborne during the stripping operations performed. The levels found were above levels considered acceptable for determining the completion of a response or abatement action and before re-occupancy of such affected areas. g. The degree of health risk associated with the levels of airborne asbestos found cannot be accurately ascertained without further investigation and exposure monitoring. 7. RECOM M ENDATIONS: a. Consistent with EPA's guidance document 560/5-85-024 Guidance for Controlling AsbestosContaining Materials in Buildings (`Purple Book*) paragraph 3.3.3, avoid removing, sanding or stripping floor tiles containing asbestos. If tiles are removed, do not sand asbestos backing material remaining on the floor. !b. Implement interim policies in regards to the above until such time that further investigation is performed and more scientific data becomes available or untD specific guidance is issued by the appropriate regulatory agencies. c. ff asbestos-containing floor tiles must be stripped, use only wet stripping methods. Institute appropriate engineering controls, work practices, air monitoring, and employee protection programs. Assess exposures to workers during stripping and consider these exposures in overall exposure assessments of employees involved in routine operations, maintenance, and repair activities. d. Considerable attention should be lent to the potential for fiber release during asbestoscontaining floor tile maintenance operations. EPA's involvement and participation is imperative in affording an adequate assessment of exposure potentials. Appropriate regulatory guidance for local education agencies must be disseminated at the earliest possible date. ATTACHMENT 1 TABLES OF RESULTS Asbestos Air Sampling Results Sligo Middle School, Montgomery County, Msrytsnd WRC-TV Washington TABLE #1 t r a n s m is s io n elec tr o n m ic r o sc o py ( t e w SAMPLE 8 JLC410198901 JLC410198902 JLC4101989O4 JLC410198905 JLC4101989O6 JIC4 10198907 JLC410I98908 JLC4101989OV JLC4101989I0 JLC410198912 JIC 4 1 0 1 9 8 9 I3 JIC410198914 SAMPLE DATE 10/19/89 10/19/89 10/19/89 10/19/89 10/19/89 10/19/89 10/19/89 10/19/89 10/19/89 10/19/89 10/19/89 10/19/89 SAMPLE LOCATION P ra -a a m p la - b a ckg ro u n d cla s s ro o m 18 P r e -a a n p le b a ckg ro u n d c la s s ro o m 18 Work a re a - M ethod # 1 8 5 ' Work a re a - M ethod 81 8 5* Work a re a - Method 82 8 2* Work a re a - M ethod 82 8 5* C lean ara a o u ts id e decon entrance Work a ra a - Method 83 8 2* Work a ra a * Method 83 8 5* Clean are a - o u ts id e decon entrance P o s t- s tr ip pro-wax aggressive 8 2* P o s t- a tr ip - pra-w ax aggraaslva 8 5* SAMPLE VOLUME IN LITERS 1199.8 1218.0 1199.8 1218.0 1199.8 1218.0 1479.0 1174.0 1192.0 1662.0 1 1 6 6 .0 1183.0 TEH ANALYSIS OF AIRI FIBER DENSITY IN S /l 4 5 .8 30.5 4 5 .8 15.3 9 1 .6 229.0 122.1 236,167.6 276,316.1 30.5 183.2 137.4 PHASE CONTRAST MICROSCOPY (K N > SAMPLE # SAMPLE DATE AMPLE LOCATION JLC41019890B JLC410198911 JLC410198912 JLC410198919 10/19/89 10/19/89 10/19/89 10/19/89 Clean araa Personal Clean area la n k - o u ts id e dscon entrance workers b re a th in g tone - o u ts id e decon entrance SAMPLE VOLUME IN LITERS 1479.0 1152.0 1662.0 PCM ANALYSIS OF AINU FIBER DENSITY IN F/M 17.8 39.5 22.5 NFO < Lea th a n NFO No F ib e r s O b s e rv e d S/MN2 S t r u c t u r e s p a r s q u a re a t I t (m e te r F/MH2 - f i b e r s p e r square a l l l l a a t a r F/CC F ib e rs p e r c it r ic c e n tim e te r S/CC S t r u c t u re a p e r cU> ANALYSIS: A i r sam ples w e re a n a ly z e d u s in g T ra n s m is s io n E le c t r o n M ic ro s c o p y (TEN) EPA le v e l I I (TANATE, < M ic ro s c o p y (PCM) NIOSH 7400 A (a s m o d ifie d b y QSHA/EPA c o u n t in g r u l e s ) .
