  • What does ATEX mean? Working in a hazardous environment

    Often, these atmospheres are created where gas, vapors, dusts and liquids are in contact with oxygen. Hazardous areas are divided into zones, where the probability of a hazardous atmosphere being present governs the explosion risk. Some areas are more hazardous than others, since it is more likely that there are gasses present.
