VDI 3492 is one of numerous VDI guidelines drawn up by the VDI (Association of German Engineers). They contain trend-setting rules and recommendations for the state of the art and for science. They are relevant for daily practice.
Wearing respiratory helmets with head protection is an important form of protection when working in hazardous environments, particularly in trade, industry and construction. This includes, in particular, possible contact with hazardous substances.
The term nanoparticle is used to describe particles with a size between 1 and 100 nanometers in height, width or length. The Greek term “nanos” means dwarf and illustrates the size dimension.
The current pandemic situation, with the tightening of coronavirus measures, has completely changed the living conditions of most people. Many are working from home to protect their health and their workplace. Often, the entire family spends almost all of their time at home without properly exchanging the indoor air at intervals due to the general closure of schools or daycare centers or the current inability to use leisure facilities outside the home.
In the acute pandemic situation with a further increase in corona cases, we offer the new Vira-Pore virus sampling cassette for air measurement of coronaviruses in indoor air for laboratory testing.
In many houses, extensive refurbishment measures are only required after many years, for example, when old plaster is knocked off or old tiles or electrical cables are removed. In order to find out whether pollutants are hidden in the old building components, measurements of harmful substances such as asbestos measurements are useful.
The measuring device SG5200 is ideal for mold measurement as well as for samples of dust fractions such as A-dust and E-dust, gases, fumes or fibers. There is a particular risk of mold during the warmer months of the year.
Behind the abbreviation TRGS stands for the Technical Rules for Hazardous Substances. These rules reflect the current state of the art, scientific findings for activities involving hazardous substances, including their classification and labeling. They are drawn up by the Committee for Hazardous Substances (AGS) and published by the Bundesministerium für Arbeit und Soziales (BMAS). The Hazardous Substances Ordinance can also be consulted.
In general, the term pollutants refers to substances that have a harmful effect on health and/or the environment.
The pollutants can be solids, gases/fumes or liquids and are usually present as mixtures of substances.
The hazard potential depends on the type of substance and the duration and frequency of exposure.
Nanoparticles are particles with a size (height, width or length) of 1 to 100 nm (nanometers). To clarify the size: A nanometer is one millionth of a millimeter.
“Nano” is derived from the Greek term nanos and means dwarf. This refers to the small size of the particles.
