For asbestos air testing, there are two primary sampling methods: PCM (Phase Contrast Microscopy) and TEM (Transmission Electron Microscopy). Both methodologies analyze for fiber concentration through pumping the ambient air into filtered air cassettes. The process usually involves running a number of high volume air pumps depending on the size of the property to achieve a volume of 1,200 liters of air. In this blog post, I will discuss the benefits and drawbacks to each method of testing.
A common question we receive when clients are concerned about asbestos is “How do you test for asbestos?” In fact, there are many ways asbestos can be sampled. These methods include bulk, air, and dust sampling. In this blog post, I will go over these methods and how to decide which testing is best suited for your situation.
When most people imagine what asbestos looks like, they often think of a white fibrous mass. However, asbestos varieties come in different shades such as brown and blue. The blue asbestos is called Crocidolite. For my fellow geology enthusiasts, Crocidolite is actually the name of the fibrous form of the blue mineral known
As we have discussed in previous blog posts, asbestos is a versatile substance. Although it is typically only thought of being used in building materials, its usage eventually branched out to Hollywood. Due to the texture and pale color of chrysotile, a common form of asbestos, it was sometimes used as a snow substitute
So you just bought your new home or are conducting renovations in your property and you discover a material that you suspect is asbestos containing. You decide to have the material tested by a licensed inspector and discover it is in fact asbestos. Now the decision comes of what to do with it.
Did you know that there are different types of asbestos? There are six different minerals that we collectively call “asbestos”. Chrysotile is the most commonly found mineral in asbestos-containing materials. According to OSHA, Chrysotile makes up 95% of the asbestos found in asbestos-containing materials in the United States. Chrysotile fibers are typically
You may have come across something called “vermiculite” in potting soil or in attic insulation. Why is it often associated with asbestos? Vermiculite is a mineral that appears in a pebble-like form. It is often gray, silver, and gold in color and can shimmer in light. Because of its insulating properties and versatility, vermiculite
In homes throughout the nation built before the 1980s, asbestos containing materials were commonly incorporated. Asbestos was used because of its high durability, fire resistance, and other favorable properties. Asbestos was used in drywall, plasters, floor tiles, HVAC insulation, plumbing insulation, adhesives, and many other products. Asbestos containing materials in the home become a
The usage of asbestos has been documented since antiquity. Before its usage in modern building materials, asbestos was used in pottery, clothing, and even ceremonial items throughout the world. Many ancient civilizations used asbestos because of its amazing properties which included fire resistance and ability to be woven and integrated into many objects. In
Air Cell refers to an asbestos-containing pipe insulation product. It has alternating layers of plain and corrugated asbestos paper. The term “Air Cell” was used as a product name by Armstrong Contracting and Supply Corporation and others. However, the term “Air Cell” can also be used in a generic manner for various types of similar
In the colorful universe of Marvel Comics, many of its superpowered characters gained their abilities via a science experiment, magic, technology, or other uncanny circumstances. In the late 1940s Marvel (known at the time as Timely Comics) created a character that drew their abilities from a real world material known as asbestos. This character took
What are the health problems associated with asbestos exposure? In this blog post I will discuss the common routes of exposure for asbestos and its health effects related to exposure. The term asbestos refers to a group of six naturally occurring fibrous silicate minerals which often have a length-width ratio of roughly 1:20. These minerals
With each passing year, the general public becomes more and more aware of indoor air quality (IAQ) issues. I thought it was because of my educational outreach efforts. Come to find out… people are more aware because of The Simpsons! I found over 20 indoor air quality related quotes from Simpsons episodes using the new website Frinkiac.com.
Now that spring is right around the corner, we have been receiving a lot of phone calls about environmental inspections and testing prior to purchasing a new property. Some people have a general idea of things they want checked out per recommendations of their traditional home inspector. Examples include potential mold in an attic or
