What is the process of sealing asbestos?
If you are permitted by law to leave asbestos in place, you will want to seal off the asbestos, a process known as encapsulation. There are two types of encapsulation: a paint-like material that is coated over the asbestos wrapping, and a self-setting cement tape that is wetted, applied and then hardens like a cast. An added benefit to encapsulation is that it prevents the distribution of asbestos fibers if you ever decide to remove the pipes or ductwork completely. You’ll be able to take the piping or ductwork out, securely sealed inside its painted or taped coating. But even when encapsulated, you must beware: if your piping or ductwork is in a livable space, such as a finished attic or basement or garage, where it might be bumped by someone moving a chair or other heavy object, there is a chance that the asbestos could be disturbed even if it has been sealed.

How did asbestos become dangerous?
The dangers of asbestos were discovered when corporate scientists began to report to their managers a rise in incidents of lung cancer among workers who assembled or installed products containing asbestos, thereby exposing themselves to dust from the fibrous mineral. Despite this knowledge, officials at some companies kept the information to themselves and continued to manufacture asbestos products at a robust pace. Although other insulating products were coming on the market at the time, such as fiberglass, manufacturers were determined to continue reaping tremendous profits from sales of their asbestos-containing products because the cost of asbestos was so low. They suppressed the evidence that their workers were dying.
How to encapsulate asbestos pipe?
You can encapsulate pipes with paint (called a bridging encapsulant) or a specially designed penetrating encapsulant, which will sink into the pipe and bond with the asbestos fibers, preventing them from flaking.

How Can I Identify Materials That Contain Asbestos?
You can't tell whether a material contains asbestos simply by looking at it, unless it is labeled. If in doubt, treat the material as if it contains asbestos or have it sampled and analyzed by a qualified professional. A professional should take samples for analysis, since a professional knows what to look for, and because there may be an increased health risk if fibers are released. In fact, if done incorrectly, sampling can be more hazardous than leaving the material alone. Taking samples yourself is not recommended. If you nevertheless choose to take the samples yourself, take care not to release asbestos fibers into the air or onto yourself. Material that is in good condition and will not be disturbed (by remodeling, for example) should be left alone. Only material that is damaged or will be disturbed should be sampled. Anyone who samples asbestos-containing materials should have as much information as possible on the handling of asbestos before sampling, and at a minimum, should observe the following procedures:
