Q: What magnification do you need to see asbestos fibers?

• <div><p>If you own a stereo microscope, you should be able to see the fibers. The stereo microscope often can perform magnification up to 50x. But unless you have experience viewing asbestos fibers, you may not know exactly what you are seeing. Some fibers are curly, while others are long and straight. Blue, brown, white, and gray colored fibers are all possible.</p></div>

Q: What products still contain asbestos?

• <div><p>There are products that still contain asbestos, but they were typically installed decades ago. Common places where you may still find asbestos-containing materials are in siding, wrapped around ductwork, in older appliances (i.e., stove and gravity furnaces), and in floors. Asbestos was primarily used as an insulator, so anywhere in an older home where you lose heat is where you will most likely find asbestos.</p></div>

Q: Can asbestos exposure result in immediate symptoms?

• <div><p>The microscopic asbestos fibers do not cause eye irritation, throat irritation, or lung irritation. If you are inhaling fibers, you will not know it. This lack of immediate symptoms is one of the reasons why asbestos is so dangerous. You cannot know for certain if you are inhaling fibers, which is why you must wear safety gear if you could have any chance of an exposure while working. </p></div>

Q: What pollutants are commonly tested for?

• <div><p>Mold, VOCs, radon, carbon monoxide, and particulate matter are typically measured.</p></div>
