Test For Asbestos – Can You Do This at Home?, asbestosdefinition.com | If you are testing for asbestos at a home for which the owner denies the presence of this deadly mineral, there is little that you can do. However, there are some things that you can do to protect yourself from exposure to asbestos in your test for asbestos popcorn ceiling.
The first thing that you need to be aware of is that testing for asbestos in a building where there is no evidence of a previous occurrence of asbestos exposure can lead to the false conclusion that the structure is free of asbestos. No one wants to look into the ceiling of their home and find that they are looking at evidence of a deadly mineral. Even the most tenacious worker will feel pretty stupid after he or she has been exposed to a sample of asbestos that is resistant to fire and weather.
It is important that you understand that testing for asbestos in a home where there is no existing evidence of the mineral is not an accurate test to perform. Any samples taken from the ceiling that appears to be exhibiting high levels of resistance to fire and weather are probably not really indicative of the presence of asbestos. There may be other reasons for the presence of the mineral in the sample. For example, the sample may have been contaminated by paint dust on the wall, or some other source of contamination.
In order to correctly test for asbestos in a home for which there is no existing evidence of the mineral, you must collect samples from all parts of the ceiling. You should use an X-ray fluorescence method to determine if there is asbestos present. With this method, you will produce a positive result if the mineral is present in the sample.
The next step is to remove all items from the sample and place them in sealed containers. You should also save the sample from the sample container for later testing. This makes it easier to collect the necessary samples in the future.
After all of the items are removed from the sample, test each item for asbestos using the procedure that you would use to test for asbestos in a building that contains evidence of previous exposure to the mineral. You should place the sample in a sealed container and seal it with a labeled wrapping. Take the samples to a local laboratory for analysis.
The samples that are deemed to be low level are analyzed by high pressure liquid chromatography coupled with mass spectrometry. High pressure carbon and methane flame atomic emission spectrometry will be used for high level samples. Even though it is possible to collect samples that contain high levels of asbestos, the chances of finding any trace of the mineral are very low.
This process involves several steps, including preparation of samples by making sure that they are properly sealed and labeled. Depending on the type of asbestos material that is suspected, different tests will be needed to identify the mineral.
For a roof, it is usually sufficient to conduct fire resistance tests. Since the risk for exposure to the mineral is eliminated by the presence of flame retardant materials in a structure, this step in the process should be the first one to be completed. If you test for asbestos in a home that contains a small amount of the mineral, this step is more likely to produce a positive result.
For a roof, the first step in the process involves placing a sample in a steel cylinder that has been lined with a layer of asbestos that has been treated with a substance that makes it very resistant to fire. This material is called Pseudacephalic Epitaph or PET, for short. The sample should remain in this position until all of the flammable material has been removed.
Then, a second sample must be placed in the cylinder. The difference between these two samples is the amount of the mineral that was present in the sample that was placed in the PET.
The amount of mineral in a sample that was placed in the PET will help determine whether the sample contained asbestos. If there is a false positive result, a third sample should be taken. All of the results should be compared in order to determine the extent of exposure to the mineral.
