Many health risks associated with various naturally occurring or produced substances are only recognized over time. It is important to protect people from these risks. Through the publication of various \u201cTechnical Rules for Hazardous Substances\u201d (TRGS), the Federal Institute for Occupational Safety and Health (Bundesanstalt f\u00fcr Arbeitsschutz und Arbeitsmedizin) has introduced occupational exposure limits (Arbeitsplatzgrenzwerte, AGW). According to the definition of the term \u201ctechnical rules\u201d, these are to be understood as a recommendation or technical proposal. If AGWs are complied with, it can be assumed that the individual hazardous substances do not have a negative effect on humans or the environment. In some cases protective measures must also be complied with. By constantly updating the rules on the basis of the current state of the art, people and the environment in Germany are protected on the one hand, while on the other hand the rules also represent a challenge in many areas of work. In the following, the current status of the technical rules in relation to ventilation in mining will be presented and their influences and challenges will be explained. What influence do the different rules have on the different work processes and what changes must be made if necessary?<\/p>\n\n\t\t

New occupational exposure limit values apply to the whole industry. Already for electrical installation work on construction sites during the milling of slots, the new limit values mean an adaptation of the previous construction sequence. In other industrial sectors, the effort is much more extensive, as these are linked to many peripheral conditions. In tunnel construction, e.\u2009g., access to the workplace is restricted and project planners and health protection coordinators are faced with major tasks.<\/p>\n

In mining, however, the most difficult conditions arise. Many workplaces with a wide variety of requirements are located in underground operations with severely restricted access to supplies.<\/p>\n

For over a year now, many companies and mining groups have been working together with machine manufacturers, health protection specialists and government agencies on future-oriented solutions to implement the new workplace limits in mining and at the same time be competitive on the international market.<\/p>\n

But what are the current rules and how must ventilation be changed?<\/p>\n\n\t\t

Health protection in mining is regulated by the Health Protection \u2013 Mining Ordinance (Gesundheitsschutz-Bergverordnung \u2013
\nGesBergV) with the Hazardous Substances Ordinance. However, this does not itself contain any direct occupational exposure limits, but refers to the Technical Rules for Hazardous Substances (Technische Regeln f\u00fcr Gefahrstoffe \u2013 TRGS).<\/p>\n

The decisive factors for ventilation and air quality are individual factors:<\/p>\n
