The member companies of the RESILIENT FLOOR COVERING INSTITUTE are manufacturers of the follow-' ing forms of resilient floor coverings which may contain some asbestos: 1. Sheet Vinyl 2. Vinyl Asbestos Tile 3. Asphalt Tile W H Y ASBESTOS IN RESILIENT FLO O R COVERINGS? Asbestos fibers have been used in the manufacture of' resilient floor covering products for more than 5 0 years. Asbestos fibers are used to provide durability to tile prod ucts. In addition, asbestos fibers in sheet vinyl backings permit these products to be installed on all grade levels. The presence of "locked-in" asbestos fibers in resilient i floor coverings provide the versatility and economy for t I which they have been noted throughout the years. W HAT ABOUT ASBESTOS? i In the past decade much attention has..ben focused on the relationship between exposure to asbestos fibers and respiratory ailments. It has been determined that inhala tion of free airborne asbestos fibers may be injurious to health. However, the asbestos fibers contained in the above types of resilient floor coverings are not free, but \ firmly encapsulated or locked-in the product during the manufacturing process. Asbestos contained therein will not become airborne during the lifetime of the product when these products are used and maintained as recom* mended by the manufacturer*. ` See "Monitoring for Airborne Asbestos Fibers: Vinyl Asbestos iloor Tile" end [ "Monitoring for Airborne Asbestos Fibers: Sheet Vinyl Floor Covering,* report f i prepared by SRI International. 1978-79. (Available on request from the ffesilient j Floor Covering Institute, 1030 15th Street. NW Suite 330. Washington. DC | 20008). ! U u-t J It is essentia! that certain precautions be observed however, when installing a resilient floor covering or when preparing or removing an existing resilient floor covering. It is the purpose of this W ork Procedures Manual to provide those precautionary steps necessary to assure the safest w ay to accomplish the work involved.

Unadhered or Loose-Lay. 2. Adhered or Cemented. 3. Peripherally adhered. Some resilient floor covering can be installed over e x isting resilient sheet vinyl floor covering ,,under certain conditions. Be sure to follow the floor covering manufac turer's instructions, regarding the conditions and floor preparation required. ' If partial or complete removal of the existing sheet v in y l1 floor covering is required, the following instructions are to.: be followed: M L Ilk II Supplies and Tools (refer Sketch 1.) 1. Broad, stiff-bladed wall scraper, or flodr scraper. 2. Utility or hook knife. 3. Tank type vacuum cleaner with disposable dust bag and metal floor tool (no brush). , 4.

Install the new resilient floor covering according to the manufacturer's instructions. Partial Removal of Existing Adhered Sheet Vinyl Floor Covering. Most felt backed sheet floor coverings can be separated in the backing or felt layer. The felt left on the floor presents a smooth surface on which some new sheet floor coverings can be installed directly. Be sure to follow the manufacturer's instructions. Use the following procedure to partially rem ove the existing adhered floor covering. Reminder: Never Sand an Existing Floor Covering a. Remove any binding strips or other restrictive moldings from doorways walls, etc. b. Make a series of parallel cuts 4 to 8 inches apart through the top layers and about halfway through the backing, parallel to the wall. c. Start at the .end of the room farthest from the en trance door^and pry up the corner of a strip, separating the backing layer. Pull ^he top layer back upon itself slowly and evenly at the angle that per mits the'best separation, and half the backing and the top layers will pull free (see Sketch 9). After it is re moved, roll up the strip face out into a tight roll.

Repeat the above on the next two strips but do not remove anymore than a total of three strips at this time. e. Remove the felt remaining on the floor in the stripped area by wet scraping.

Thoroughly wet the residual felt with this solu tion. W ait a few minutes to allow the solution to soak into the felt (see Sketch 11). 3. Stand on the remaining floor covering (not the felt) and use the stiff-bladed scraper to scrape up the wet felt (see Sketch 13 below). 4. Repeat the above on the next series of strips. Do only one three-strip area at a time. Stand on the re maining floor covering or dean floor (do not1/ stand on the felt) to scrape up the felt. ; 5. Repeat this operation until the felt has been removed from the whole floor. Close full bags' ' tightly, and seal securely for disposal.

Scrape all felt from this floor area before proceeding further. RESILIENT TILE FLOOR COVERING Preparation of Floors With Existing Resilient Tiles to Receive New Resilient Floor Covering. Some resilient floor coverings can be installed over e>/ isting resilient tile installations. Follow the installation ir structions published by the manufacturer of the new floe covering when a new resilient floor covering is to be ir! stalled on a surface presently covered with a resilient floe1 covering. These instructions will tell you what must b done to the existing surface before the new resilient floe covering can be installed. Caution: Never Sand an Existing Tile Installation (see Sketch 4). -, Complete Rem oval of Existing . . Resilient Tile Floor Covering. Supplies and Tools (refer Sketch 14) 1. H eavy duty wall scraper with approximately 4" blade and 6" to 8 " handle. 2. Hammer 3. Commercial type hand held hot air blower. 4. Heavy duty impermeable trash bags (or closed im permeable containers), ties and labels. S k etch 14. Tools and supplies for tile removal. a. Those areas normally exposed to heavy foot traf fic patterns usually have tiles adhered the tightest. As a matter of good practice in starting the tile removal, those sections which receive least traffic should be the locations selected for starting the removal of the tile. Since tiles are normally in a 9 " x 9 " or 12" X 12" dimension, it should be the goal to remove individual tiles as a complete unit. b. Start the removal by carefully wedging the wall scrape^ in the seam of two adjoining tiles and gradually forcing the edge of one of the tiles up and away from the floor (see Sketch 15). Do not break off pieces of the tile but continue to force the balance cf the tile up by working the scraper beneath the tile and exerting both a forward pressure and a twisting action on the blade to pro mote release of the tile from the adhesive and the floor. 14 impermeable trash bag or closed impermeable container which will be used for disposal. d. W ith the removal of the first tile accessibility of other tiles is improved. Force the wall scraper under the exposed edge of another tile and con tinue to exert a prying twisting force to the scraper as it is moved under the tile until the tile releases from the floor. Again, dispose of the tile,' . and succeeding tiles by placing in the heavy duty bag or closed container without additional break ing. e. Some tiles will release quite easily while others re quire varying degrees of force. W here the adhesive is spread heavily or is quite hard, it may prove easier t a f o r c e the scraper through the ' tightly adheren ares-by striking the scraper han-, die with a hammer usjng blows of moderate force while maintaining the scraper at a 2 5 * to 3 0 * angle to the floor (see Sketch 16). 1< S k etch 1 6 . Difficult tile removal am often be accomplished by striking the scraper l '.mile with a hammer or mallet as shown. f. If some areas are encountered where even the technique detailed in the previous paragraph proves to be inadequate, the removal procedure can be simplified by throughly heating the tile(s) with a hot air blower until the heat penetrates through the tile and softens the adhesive. NOTE: Handle the hot air blower carefully to avoid per sonal burns (see Sketch 17 below). g. As'small areas of subfloor are cleared of tile th adhesive remaining on the floor must be scrapet up with the 4 " hand scraper until only a thir smooth film remains. In those areas when deposits are heavy or difficult to scrape th< removal can be expedited by heatipg with the ho air blower prior to scraping. Deposit scrapings it a heavy duty impermeable trash bag or closed im permeable container. h. As indicated in previous paragraphs, tiles shoulc be placed immediately in a heavy duty im permeable trash bag or closed impermeable coni! tainer. Do not attempt to break tiles after they aNj in the bag. W hen all tiles have been removed from the floo and placed in heavy duty bags or closed con tamers, seal the bags securely for disposal (sei Sketch 18 below) and mark: "Caution-- Contain Asbestos--Dispose in an approved land fill only.
