Directive 1999/92/EC Technical appendix Directive 1999/92/EC Article 137 of the European Community Formation Treaty set out the minimum standards in order to improve workers’ health and safety, this can also be put at risk by explosive atmospheres. An explosive atmosphere is a mixture of air and flammable gasses, vapours, mists or dust under atmospheric conditions where, following successful ignition, the burning process will propagate throughout the whole unburned mixture. The directive 1999/92/EC was transferred into national law. Compliance with the minimum standards contained in this directive does not guarantee that all relevant national laws are met. It is possible for local regulators to introduce more stringent requirements. The employer is required, according to the directive 1999/92/EC, to take measures to ensure the health and safety of the employees. One measure is the division of the area into zones where explosive atmospheres could be present. Unless the risk analysis conducted by the employer indicates otherwise, all areas where an explosive atmosphere may be present must be equipped with devices and protective systems that meet the relevant category of the ATEX directive 2014/34/EU. In particular in these zones the following categories of equipment should be used, as long as they are suitable for use with gases, vapours, mists or dusts: • In Zone 0 or Zone 20: category 1 devices, • In Zone 1 or Zone 21: category 1 or category 2 devices, • In Zone 2 or Zone 22: category 1, category 2 or category 3 devices. Zoning according to the directive 1999/92/EC Explosion risk areas are classified into zones according to likelihood of explosive atmospheres occurring and their persistence. Zone 0 An area which has a potentially explosive atmosphere that is a mixture of air and flammable gases, vapours or mists. The mixture is either permanently present or frequently present over long periods of time. Zone 1 An area in which during normal operations a potentially explosive atmosphere of air and flammable gases, vapours or mists can occasionally form. Zone 2 An area for which during normal operations there is at most only a short-term occurrence of a potentially explosive atmosphere of mixtures of air and flammables gases, vapours or mists. Zone 20 An area where a potentially explosive atmosphere is present in the form of a flammable dust cloud in the air. This cloud is either permanently present or frequently present over long periods of time. Zone 21 An area where, during normal operations, a potentially explosive atmosphere in the form of a flammable dust cloud in the air can occasionally form. Zone 22 An area where, during normal operations, a potentially explosive atmosphere in the form of a flammable dust cloud in the air is not normally present or only present for a short time. W For the risk assessment and as well as the zoning concept described above, Ex devices themselves can be considered in an alternative process which uses the equipment protection level (EPL). These protective levels determine the internal ignition risk of a device where the sort of applied protection does not play a role. W.2 2031180000
