At the beginning of this video, we gave examples of _____(1) types of environmental _____(2) which exist on or off a property. Let's _____(3) some of the more common _____(4) more closely.

_____(5) is any of a _____(6) variety of fibrous materials which are commercially _____(7) from natural deposits in the earth.

Construction materials which _____(14) friable asbestos are those that can be _____(15) and _____(16) or reduced to powder by hand pressure when dry. Construction materials which contain non-friable asbestos cannot be _____(17) by hand pressure. _____(18), think of asbestos in the context of whether or not you can crush it with your hand.

Of course, on the _____(19) of stucco or plaster, the asbestos may become friable since the material is disturbed and broken down for removal, creating particles which may become airborne and inhaled.
