It's not possible for you to tell whether a material in your home contains asbestos simply by looking at it. If you suspect a material within your home might contain asbestos (for example floor tile, ceiling tile or old pipe wrap) and the material is damaged (fraying or falling apart) or if you are planning on performing a renovation that would disturb the material, the EPA recommends that you have it sampled by a properly trained and accredited asbestos professional (inspector). The professional then should use a qualified laboratory to perform the asbestos analysis. Also, you may learn more about whether the replacement materials you intend to install might possibly contain asbestos by reading the product labels, calling the manufacturer, or by asking if your retailer can provide you with the Material Safety Data Sheet (MSDS) for the product(s) in question.
