5.5 Limiting the areas in which Asbestos dust may arise

Work areas in which Asbestos or Asbestos containing products are processed cannot typically be kept completely free of Asbestos dust, at least not through room air exhausting.

For this reason, such areas must be labelled and isolated so that the exposure cannot be carried over to neighboring rooms. This presumes an areal separation between Asbestos operations and others. Whether air transfer tubes are needed to prevent the spread of contaminated air depends on the individual case. Frequently, a slightly lower pressure in the contaminated area is sufficient.

The Asbestos particulates exhausted from the operating stations and rooms must be cleaned in particulate filters before being released outdoors. Filtering separators are used for the cleaning of Asbestos contaminated exhaust. The guideline value for the cleaned air emitted is defined as 0.1 mg/m³ in the Technical Instructions on Clean Air (Technischen Anleitung zur Reinhaltung der Luft).
