The quality of the air within working rooms must more or less correspond to outside air. From a health point of view, the size of the dust particles is decisive in addition to the pollutant contents of the dust.

Health effects of high dust exposure

A particle which has a diameter of larger than 10 μm (1 micrometer is one thousandth of a millimeter), so-called coarse dust, gets caught more or less easily on nasal hairs or mucous membranes. Smaller and tiny dust particles (fine dust, ultra-fine particles) can penetrate deep into the lung via the windpipe and bronchiae. For this reason, fine dust is also termed inhalable or respirable dust.

Based on: Hazardous substances directive (GefStoffV), technical regulations for hazardous substances (TRGS), particularly TRGS 900
