Finding and removing asbestos

Proper removal of abestos

The production of asbestos and its products began in the mid-19th century. In fact, asbestos is a mineral belonging to the fibrous silicates (fibrous derivative belonging to the group of serpentine or amphibole minerals). The fibrous serpentine is called chrysotile asbestos. Amphibole asbestos is amosite (grunerite), anthophyllite, actinolite, tremolite and crocidolite (ribecite). By its chemical composition, chrysotile asbestos is a hydrosilicate of magnesium; amphibole asbestos also contains iron, calcium and sodium. Asbestos is fire and weather resistant, a poor conductor of heat, electricity and sound, has relatively high tensile strength, is elastic, resistant to bases and most acids, with a high surface area and good adhesion to reinforcements; and is also, decorative. Thanks to these properties, this material is considered indispensable in many branches of economy. The industry mainly uses chrysotile, crocidolite and amosite asbestos.

Asbestos has also been found in beverages where production filters containing asbestos or water contaminated with asbestos were used.

To determine the pollution of asbestos in the air, an air sample shall be collected from the examined area using a pick-up collector. There are different types of pick-up collectors, but mostly the air will be sucked (for example, using a vacuum pump) through a filter, on which the air pollution settles. The type of filter and its subsequent disposition depends on the method of analysis. For example, in the case of phase-contrast microscopy, membrane filters handled in acetone-triacetin will be used. Asbestos and its types are identified using microscopes and analysers, for which light, raster and transmission electron microscope and x-ray micro-analyser and diffractometer is suitable. Asbestos fibres are identified by their shape, optical properties and chemical composition. Asbestos fibres are difficult to distinguish from several other mineral and organic materials, and therefore the analysis equipment should be selected skilfully.

  • mapping of the areas of asbestos
  • proper removal

Think about your health and safety. PLC Windair will start the campaign “Terve Maja". Ventilation systems accumulate dust and grease when operating, which prevent clean air flow in the building. The layers of accumulated dust and grease create good conditions for ticks, fungi and other harmful micro-organisms to grow and spread. Occasionally, harmful micro-organisms can drop from the ventilation systems and get among people. Infections and diseases such as allergies, the flu and many others can easily move from a sick person to a healthy person through the ventilation.
