Explosion protection is relevant in all operations where flammable substances are produced, processed, stored, disposed of, or transported. Flammable gases, vapors, or dust can mix with oxygen in the air and can lead to rapid combustion or explosions with only a small amount of ignition energy. This often results in serious personal and property damage. The affected industries are diverse, ranging from pharmaceuticals to mining to the food industry. To avoid explosions in practice and to sustainably protect businesses, those responsible must know and assess the hazards. Only after a proper assessment can the necessary countermeasures and protective measures be implemented. National and international regulations, guidelines, and standards must also be taken into account.
