Crocidolite – usually blue or grey, these fibres are thin, brittle and needle like in appearance. Amosite – brown asbestos that, like crocidolite, are normally comprised of needle like fibres.

All forms of asbestos are fibrillar in that they are composed of fibers with breadths less than 1 micrometer in bundles of very great widths. Asbestos with particularly fine fibers is also referred to as "amianthus".

One quick way to rule out asbestos is to look at the core of the tile. If it is brown/tan, it is not likely asbestos. If the core is white or gray, then there is a chance it could be asbestos. It may also just be cellulose (the most common material of ceiling tiles).

Vermiculite is a spongy material that is dark brown to golden brown in color. It is shaped like flakes when dry. Perlite is a porous pumice-like material that looks like white granules. Sometimes perlite is mistaken for tiny plastic foam balls when used in potting soil mixtures.

While asbestos is a natural material and fiberglass is man-made, the two materials are often compared because they're both fibrous. This quality made fiberglass a good substitute once the health effects of asbestos became apparent. It also has the heat-resistant qualities that made asbestos so desirable for insulation.

The mastics or adhesives used to install vinyl products also often contained asbestos, though asbestos fibers in adhesives are less likely to become airborne. Asbestos vinyl sheet flooring poses a significantly greater asbestos exposure risk than floor tiles or wallpaper.

Similar to mica, vermiculite comes in the form of small granules whose color varies from silver-gold to gray-brown (see photo below). If you discover a similar substance between the joists of your roof, it's a safe bet to say that it is insulated with vermiculite.

roof insulation. 1. A board-type product, usually of low or medium density, made of mineral fibers, cellular glass, foamed plastic, lightweight concrete, wood fiberboard, or other materials, one or both sides of which may be faced with another material; provides thermal insulation in a roofing system.

One of the most common flooring adhesives is called “black asbestos mastic.” Wallpaper and wall panels were commonly installed using asbestos adhesives. When wall panels are removed, the adhesive left behind is often visible as brittle old daubs.

Asbestos, like crystalline silica, is deemed safe if left undisturbed. However, asbestos instantly becomes hazardous once damaged. Even a crack or rupture will caused asbestos particles to become airborne. Crystalline silica is also easily damaged, but the dust only becomes harmful if inhaled in large quantities.

Chrysotile (white asbestos) is the most commonly used form of asbestos. It can be found today in the roofs, ceilings, walls and floors of homes and businesses. Manufacturers also used chrysotile asbestos in automobile brake linings, gaskets and boiler seals, and insulation for pipes, ducts and appliances.

Whether there is asbestos in your home's drywall or not, most sheetrock mud (also known as wall-joint compound) which was sold between 1940 and 1980 did contain asbestos fiber. This product came in two forms and was used to fuse the seams between drywall panels once they were installed.

Is working with asbestos roofing and siding hazardous? Asphalt or cement roofing and siding that contain asbestos, when intact and in good condition, are generally considered nonfriable and are not hazardous.
