Description
|
This standard establishes the classification of hazardous areas where explosive mixtures of flammable gases or vapors mixed with air (see Notes 1, 2 and 3) may arise and may then be used as a basis to support the proper selection and installation of equipment for use in a hazardous area. This standard applies to areas where there may be an ignition hazard due to the presence of flammable gas or vapour, mixed with air under normal atmospheric conditions (see Note 4), but it does not apply to a) mines susceptible to firedamp; b) the processing and manufacture of explosives; c) areas where a hazard may arise due to the presence of combustible dusts or fibers (refer to IEC 61241-10/IEC 60079-10-2); d) catastrophic failures or rare faults which are beyond the concept of abnormality dealt with in this standard (see 3.30 and 3.31); e) rooms used for medical purposes; f) domestic premises. This standard does not take into account the effects of consequential damage. Definitions of terms are given together with the main principles and procedures relating to hazardous area classification. For detailed recommendations regarding the extent of the hazardous areas in specific industries or applications, reference may be made to national or industry codes relating to those applications. Notes 1 Flammable mists may form or be present at the same time as flammable vapors. Liquids not considered to be hazardous in terms of this standard (due to the flash point), when released under pressure may also generate flammable mists. In such cases, the strict application of area classification for gases and vapors may not be appropriate as the basis for selection of equipment. Information on flammable mists is provided in Annex F. 2 The use of IEC 60079-14 for selection of equipment and installations is not required for mist hazards. 3 For the purpose of this standard, an area is a three-dimensional space. 4 Atmospheric conditions include variations above and below reference levels of 101,3 kPa (1 013 mbar) and 20 °C (293 K), provided that the variations have a negligible effect on the explosion properties of the flammable materials. 5 In any process plant, irrespective of size, there may be numerous sources of ignition apart from those associated with equipment. Appropriate precautions will be necessary to ensure safety in this context. This standard may be used with judgement for other ignition sources. |
