Asbestos - What Is It?

Asbestos refers to a group of naturally occurring minerals that form in bundles of fibers, which can be separated into thin threads. Known for their heat resistance, chemical durability, high tensile strength, and electrical resistance, these fibers were widely used for thermal and electrical insulation. Due to these properties, asbestos was commonly added to various building materials.

There are several types of commercial asbestos:

Chrysotile (White Asbestos) – The most commonly used type, accounting for about 99% of asbestos currently used in the United States.

Crocidolite (Blue Asbestos) – Known for its thin, needle-like fibers.

Amosite – Typically characterized by its brown fibers.

Anthophyllite – Usually found in shades of gray.

Asbestos fiber masses can easily break down into fine dust particles that become airborne and cling to clothing. When inhaled or swallowed, these fibers pose serious health risks. Asbestos-containing materials are classified into two categories: friable and non-friable. Friable materials can be crumbled into powder by hand pressure, making them more likely to release asbestos fibers into the air. These materials require strict control measures to prevent fiber exposure. Non-friable materials, on the other hand, are more stable and less likely to release fibers under normal conditions.

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

Hi Dave,

I just wanted to write and thank you very much for doing our inspection today. You really took an awful lot of extra time to explain things to us. It was a huge help and by far my favorite part of this whole home-buying process. In addition to drawing our attention to the major projects that need to be undertaken right away or in the near future, I was glad that you were also so thorough as to point out smaller things and provide suggestions for fixes that we'd be able to do ourselves. Thanks again for all your effort. I'm finding your "Know Your Home" book a great source of information along with your report. I'll no doubt have some questions for you at some point and really appreciate your willingness to answer them. Have a great rest of your weekend!

Take care,

Sean
