Asbestos - What Is It?

Asbestos - What Is It?

 

Asbestos is the name given to a group of minerals that occur naturally as bundles of fibers which can be separated into thin threads. The fibers are heat resistant, resistant to chemical attack, have excellent tensile strength and have high electrical resistance. These properties make asbestos a useful material for electrical and thermal insulation. It was often added to many building materials for this reason.

 

There are several types of commercial asbestos...

CHRYSOTILE or WHITE ASBESTOS accounts for about 99% of asbestos currently used in the United States.

CROCIDOLITE or BLUE ASBESTOS

AMOSITE, which usually has brown fibers.

ANTHOPHYLLITE, which usually has gray fibers.

Asbestos fiber masses tend to break easily into a dust composed of tiny particles that can float in the air and stick to clothes. The fibers may be easily inhaled or swallowed and can cause serious health problems. Asbestos containing materials are therefore divided into two categories: friable and non-friable. Friable means that a material is able to be reduced to powder by hand pressure. Asbestos containing materials that are friable, by their nature, have a much greater tendency to release fibers. They require specific control measures to prevent releasing fibers into the air. Conversely, non-friable asbestos containing materials, by their nature, do not want to give up their fibers into the air.

Here is what my clients have to say about my home inspection services:

Hi Dave,


I want to thank you for the home inspection you did for us at 144 Avis Ave. in Dracut MA. We did not get the house because the home owners did not want to split the cost of fixing that wall. I had gotten two estimates, one from a landscaper and one from a Mason. Both gave an estimate of $15,000.00, for which I am grateful for your inspection and pointing out the wall problem. It would of been an undue burden on us, not to mention I am also grateful about the radon testing also. I just got the results today and they came back at 7.5 and 8.4, so that would of been another expense. I do hope that when we find a new house that you will be able to do our home inspection. Your fee was a drop in the hat, to what it would of cost us to fix the wall and then the cost of venting the basement. My husband was also very impressed with your report and how well it was written. Just wanted to drop you a line to let you know what happened, and hopefully will be doing business with you again very soon.


Have a Good Day
Jackie Sliney
