All You Should Know About Asbestos Soil Contamination
Before the 90s, asbestos was used as a building material because of the great properties it possesses. One of the properties of asbestos is that it is fireproof. However, a research study was carried out on asbestos and it was confirmed that the material causes life threatening illnesses to human beings. Since then, asbestos has been banned in most parts of the world Air testing.
Asbestos soil contamination occurs in three main ways which are:
– Careless disposal of asbestos containing materials into an area.
– The area may have been used as an asbestos disposal ground in the past.
– Asbestos materials may be falling off from a building built before the 90s.
Types Of Asbestos And The Risks Involved
The soil in your area may be contaminated by either friable or non-friable asbestos. Friable asbestos is more dangerous and fragile as it contains loose asbestos fibres which are harmful to human beings if inhaled. They also become airborne easily. Constant inhalation of this type of asbestos causes severe illnesses which may lead to death. The effects set in, years after exposure to the harmful substance. It’s recommended that friable asbestos is removed from the site immediately to reduce the risks.
Non-friable asbestos is less harmful as long as it is not tampered with. This is because its fibres are bonded together. You can cover the area contaminated with non-friable asbestos and seal it off to ensure that the ACMs are not tampered with and prevent further contamination. To do this, you can use duct tape, coating and sealant.
Hiring a professional to inspect contaminated soil and check for the type of asbestos present in the soil is the way to go. The expert will also determine the nature and quantity of asbestos, and risks involved. After inspection, the expert will carry out removal and disposal of the harmful material.
How to Dispose of Asbestos
The two main methods used to dispose of asbestos are:
– Land filling – In this method, all contaminated soil is removed and substituted with good, uncontaminated soil. This is the most expensive method but most effective. The cost is usually higher because the work is extensive, involving huge quantities of soil.
– Segregation – In this method, a portion of the contaminated soil is treated at a time until all the soil in the area is free of asbestos. It is cheaper to use this method as you will only have the soil treated, not replaced. It’s also time saving as it doesn’t take long for the task to be completed.
