It is also effective as a reinforcing or binding agent when combined with cement or plastic. Many products which at one time contained asbestos are either no longer in use or have been replaced. The uses for asbestos ranged from products in which the fibres were well bound to friable products in which the fibres could easily become airborne. The construction industry was the main user of asbestos products. Sprayed insulation, stucco and joint cements manufactured in Canada and the United States no longer contain asbestos in an unbound form. Building materials containing asbestos in a bound form are typically found in the following locations and products: Building exteriors asbestos cement siding panels flat, corrugated, shingles or accent panels roofing felts and mastics asbestos cement soffits flat or perforated panels building overhangs thermal spray asbestos cement roof panels corrugated stucco

5 duct tape duct expansion/vibration isolation joints incandescent light fixture backing wire insulation Building products containing asbestos in an unbound or loosely bound form include: insulating cements textiles not saturated, for lagging, curtains or clothing sprayed insulation fire resistant, acoustic, thermal, condensation control vermiculite insulation (may contain tremolite asbestos as a contaminant) produced from the Libby, Montana mine by W.R. Grace and Company and known by the brand name Zonolite. insulation block magnesia or calcium silicate The list of products containing asbestos which are used in applications other than construction include: bound-fibre products textiles and catalyst supports plastics brake linings, brake blocks, clutch facings non-bound fibre products such as millboards and papers gaskets, packings some electrical insulation and filters or filter aids

6 Non-friable products which may contain asbestos pose little danger of releasing airborne fibres unless they are cut, broken, sawn, ground, sanded or are in deteriorating condition.
