Fiber measurements of asbestos fibers with GSA measuring devices SG12
Our SG12 measuring device can be used to carry out fibre measurements in the event of potential health risks from asbestos. The measuring device SG12 is suitable for fibre measurements of asbestos fibers indoors.
If exposure to asbestos fibers is suspected, an expert asbestos test is an advantage. We will be happy to answer any further questions you may have.
Term asbestos
The term asbestos describes naturally occurring fibrous minerals with a diameter of between 0.1µm and 2µm.
The properties of asbestos, such as chemical and thermal resistance, led to its widespread use.
Due to its low flammability and good thermal insulation, asbestos was also frequently used in private house construction.
Typical uses include window putty or roof tiles. Houses built between 1960 and 1990 are particularly likely to be contaminated.
The use of asbestos in construction has been banned in Germany since 1993. Another indication of the use of asbestos is its appearance. It often has a grey-greenish color and fibrous structures can be seen if it is already damaged.
What are the dangers of asbestos?
When inhaled, the fine fibers of asbestos can enter the lung tissue and cause severe irritation. The repeated irritation of the alveoli triggers inflammation and scarring of the tissue. Long-term exposure to asbestos fibers can lead to so-called asbestosis (“asbestosis lung”).
Asbestos discovered – fibre measurements of asbestos fibers
If there is a suspicion of asbestos exposure during renovation or refurbishment work, a number of safety aspects must be observed. Personal protection and the exclusion of a health hazard are always paramount. Protective clothing and a respirator mask (class FFP-2) are therefore essential.
There are various options for carrying out a refurbishment:
- Removal: the contaminated elements are completely removed and disposed of professionally. This method is usually the most expensive option, but offers the greatest protection for all those affected
- Sealing: affected slabs (e.g. on a terrace) are sealed with a special medium so that no more harmful fibers can be released.
- Spatial demarcation: if possible, the asbestos material is completely covered or encased; this method is also relatively inexpensive, as no disposal is required.
The last two methods are preferred for private renovations because they are relatively inexpensive. However, complete removal of the asbestos material is the safest way to rule out any further risk. If there is any doubt about the correct handling and disposal, it is advisable to hire a specialist company.
