Asbestos air testing under VDI 3492
Do you need to assess airborne asbestos fibres or arrange a check after asbestos removal? Polluants.ch offers air testing under VDI 3492, with the scope defined around your situation.
What is air testing for?
Testing building materials and measuring airborne fibres answer different questions. A materials survey locates asbestos-containing elements; air testing describes concentrations during sampling and under the conditions recorded.
Damaged materials, concerns about a room or checks after building work: we review the context before defining sampling locations and planning the visit.
After asbestos removal
Visual inspection and air testing contribute to deciding whether containment around a remediated area can be removed. The Swiss Asbestos Forum guide, published by Suva, explains how these checks work together and the independence required from the asbestos removal company.
Send the survey report and details of completed work. We clarify which checks are included, access conditions and the timing of sampling with the parties involved.
Preparing the measurement
- Describe the context. Address, rooms, condition of materials and completed or planned work.
- Define the scope. Purpose, sampling points, sampling conditions and access.
- Carry out sampling and analysis. Testing follows the protocol selected for the assignment.
- Explain the results. The report records locations, conditions, findings and their interpretation.
What the result can establish
A measurement describes a situation under specified conditions. It does not guarantee that all building materials are asbestos-free and does not replace a pre-renovation survey.
The sampling points, additional checks, price and schedule are specified in the quotation. This page concerns airborne asbestos; for radon, see our specialist activity Stop-Radon.
Information for your enquiry
If available, include the asbestos survey, work description, plans of the affected areas and the intended date for rooms to be used again. These details help us prepare the assignment.
