Asbestos Plastics, Resin, Bitumen & Vinyl
Location / Use: Thermoplastic floor tiles, PVC vinyl floor tiles and unbacked PVC flooring. Asbestos paper backed PVC floors. Magnesium oxychloride flooring used in WCs, staircases and industrial flooring. Reinforced PVC cladding. Reinforced plastic and resin used for toilet cisterns, seats, banisters, window seals, lab bench tops. Asbestos bitumen coatings (car body underseals, gutter linings, floor adhesive and wall coverings).
Asbestos Content and Type / Date Last Used: Thermoplastic floor tiles up to 20% asbestos. PVC tiles and flooring normally 7% chrysotile (white) asbestos. Magnesium flooring about 2% asbestos. Panels and cladding 1 – 10% asbestos. Reinforced resins and plastics usually contain 1 – 10% chrysotile (white) asbestos. Some amphiboles were used to give improved acid resistance, e.g. car batteries. Adhesives may contain up to a few percent chrysotile (white) asbestos, used up to 1992. Bitumen coatings normally 8% chrysotile (white) asbestos, again used up to 1992.
Ease of Fibre Release and Product Names: Asbestos floor tiles and coverings are unlikely to release fibre under normal service conditions. Fibre may be released when material is cut. Plastics and resins are unlikely to release fibre and have limited emissions during cutting. Bitumen is unlikely to release fibre, however glues and sealants must not be burnt after removal.
