The primary purpose of an asbestos survey and report is to accurately determine if an existing structure contains any asbestos-containing materials (including ACMs) before demolition. This method also includes a site survey, sampling, and lab testing of all materials intended for demolition. The duration of this inspection can last from one day to four days, depending on the scope of work, the facilities of the affected structure, and many other factors. It is usually done after the demolition of any affected structures. However, in cases where the cause of the collapse is determined after demolition, it is often necessary to perform the asbestos survey and report as soon as feasible.
Both types of asbestos surveys are done at the same time, although the methodologies used are generally different. In the visual inspection process, a qualified person, usually a structural engineer, is sent to the premises to find out if there are materials containing asbestos in the area. In addition to this, tests are also conducted to check the stability of these materials. For this reason, only structural engineers are usually called for this type of management survey. Asbestos content is then determined for the most appropriate course of action.
Visual inspections can be performed on structures that have only one level. For structures that have more than one level, only the first level must be inspected. Structures with more than two levels are usually inspected by two different surveyors. In cases that a building may require both visual and soil asbestos surveys, then a single surveyor is charged with the responsibility of determining asbestos concentration in the whole area of the property or building. For this reason, when a two-level property needs to be inspected, it is usually done so by one surveyor and the owner gets the second surveyor. Both of them are trained and competent to do the job.
When a property owner has to undergo an asbestos survey, the first step is usually to let the surveyor know where the material is located. The next step is to let them know the purpose of the survey. Usually, the purpose is for the surveyor to obtain samples and soil samples for laboratory analysis. For instance, if a building is being inspected for insulation, then samples of insulation material will be taken in order to determine if asbestos materials are present in the wall cavities. A typical sample from insulation materials will contain more than 200 particles. Samples taken from soil samples will also contain more than 200 asbestos particles.
When ordering an acm survey report, you should request for the sample collection site, which is usually done on the premises of the suspected contamination. If asbestos particles are detected during the sampling process, they will be immediately removed from the site. This is why it is important for you to let the surveyor know the exact location of your sampling point so that the sample collection can take place on the area that is not contaminated. You don’t have to worry about the asbestos content present in the soil because the surveyor will test the soil for its asbestos content prior to sampling the area.
Before calling a professional asbestos management surveyor, you need to make sure that the suspected contamination has been addressed. If you are satisfied with the results of the visual inspection and the laboratory analysis, then you can make the final decision whether to proceed with the asbestos survey. If the results of the visual inspection and the laboratory analysis show that there is no presence of asbestos in the area, then you don’t have to contact a surveyor anymore. However, if you find that asbestos is present in the area, then you will need to call the asbestos management surveyor again.
The third step when dealing with asbestos surveys is to have the sample tested for airborne asbestos fibers. Airborne asbestos fibers will cause health problems like lung cancer if they are inhaled. Air sampling is the most sensitive test to perform during an asbestos survey since the particles that are being searched for are often microscopic. It is important to perform the air sampling before the ground penetration survey is performed. By doing the air sampling right after the ground penetration survey, you will be able to determine whether there are asbestos fibers present or not.
Finally, you should take note that sampling is done during an asbestos survey must be done before demolition or renovation activities are going to take place. demolition or renovation activities can disturb the asbestos and degrade its efficiency. The disturbance should be done in such a way that the asbestos survey is not hampered.
