Especially from the 1930s to 1970s, asbestos was used very widely in insulation for the electrical system and the building, and in other building materials. A scary amount of asbestos is used even today, but not nearly as much as before the 1980s. In 1989, the United States banned and then phased out asbestos use in insulation. This happened soon after asbestos became widely known as a carcinogen. Asbestos-containing materials which are damaged or friable pose huge health risks to anyone who comes across them, because the materials may release asbestos fibers into the air.
When are asbestos surveys done? Asbestos surveys are often required for commercial real estate financing or transactions, before a building is demolished or renovated, or after a building is damaged, whether by something natural (such as a flood), or unnatural. Because asbestos use in the United States has, sadly, not stopped, it is a good idea to have an asbestos survey done if suspected asbestos-containing materials are identified, regardless of the building's age. Especially if the materials are in poor condition, don't put the testing off. Because many asbestos materials are still sold, it is federally required that before demolition or renovation, suspected asbestos-containing materials be identified. Many places will not give permits until that happens.
There are various types of asbestos surveys, which all have different jobs they do best. An asbestos survey is a necessary step to take to avoid asbestos exposure. Why? While building materials can be identified as suspected of containing asbestos visually, to confirm the suspicion, a test is necessary.
One of these tests is an Asbestos Screening, also sometimes called a transactional survey. This is best for when damaged materials suspected of containing asbestos are being fixed. In an Asbestos Screening, samples are taken from materials suspected of containing asbestos. An Asbestos Screening focusses on damaged and potentially friable materials suspected to contain asbestos. Asbestos Screening is often used on the Department of Housing and Urban Development's projects.
A Limited Asbestos Survey is another type of asbestos survey. It includes a detailed sampling of materials suspected of containing asbestos. The sampling in a Limited Asbestos Survey is based on the customer's need. The samples might be taken from anywhere expected of containing asbestos, such as the roof, walls, or siding.
A Path of Construction / Pre-Renovation Survey is a detailed inspection of the building's materials. The main difference from other asbestos surveys is the testing only includes where construction will occur and building materials. No air tests, and no tests of the whole building. This may be something one would use when renovating a storefront in a strip mall, for example. The idea is that the renovation doesn't release asbestos into the air of the building, because the asbestos is removed, using proper safety precautions, before other work is done.
Another type of asbestos survey is the Pre-Demolition Asbestos Survey. This is, by far, the most comprehensive testing of a building. The testing involves everything, inside and outside. Because it is done in preparation for demolition, it follows destructive sampling protocols. This type of survey requires the destruction of parts of the building to find asbestos-containing materials behind walls, under floors, and in other areas that are difficult to access.
An asbestos survey is the first step to safe renovation or demolition, and in some places, getting a permit. After a survey, many steps can be taken beyond removal. Some of these are abatement oversight, the development of an operations and maintenance plan (also called O&M), air monitoring, and clearance sampling, which makes sure asbestos is not in the air after removal
