ATEX Zone 2: Understanding Hazardous Area Classification

ATEX Zone 2 refers to a hazardous area classification system used in Europe for the designation of areas where explosive atmospheres may occur. Zone 2 is classified as an area where a mixture of air and flammable substances in the form of gas, vapor, or mist is not likely to occur in normal operation but may occasionally occur for short periods. Examples of zone 2 locations include petroleum refineries, chemical plants, and gas storage facilities. In these areas, specific safety measures and equipment must be used to prevent the ignition of explosive atmospheres.
