Sprogiosios atmosferos. Sprogimo prevencija ir apsauga nuo jo. 2 dalis. Pagrindinės kasybos sąvokos ir metodika

This document specifies methods for explosion prevention and protection in mining by outlining the basic concepts and methodology for the design and construction of equipment, protective systems and components. This document applies to Group I equipment, protective systems and components intended for use in underground parts of mines and those parts of their surface installations at risk from firedamp and/or combustible dust. NOTE Detailed information on specific equipment, protective systems and components is contained in the relevant individual standards. Safety-relevant data regarding flammable materials and explosive atmospheres are required for the design and construction of the explosion protection measures. This document specifies methods for the identification and assessment of hazardous situations that may lead to explosions and describes the design and construction measures appropriate for the required safety. This is achieved by: — risk assessment; — risk reduction. The safety of equipment, protective systems, and components can be achieved by eliminating hazards and/or limiting the risk, i.e.: a) by appropriate design (without using safeguarding); b) by safeguarding; c) by information for use; d) by any other preventive measures. Measures in accordance with a) (prevention) and b) (protection) against explosions are dealt with in Clause 6 of this document; measures according to c) against explosions are dealt with in Clause 7 of this document. Measures in accordance with d) are not described in this document. They are dealt with in EN ISO 12100:2010, Clause 6. The preventive and protective measures described in this document will not provide the required level of protection unless the equipment, protective systems and components are operated in line with their intended use and are installed and maintained according to the relevant codes of practice or requirements. This document is applicable to any equipment, protective systems and components intended to be used in potentially explosive atmospheres. These atmospheres can arise from flammable materials processed, used or released by the equipment, protective systems and components or from materials in the vicinity of the equipment, protective systems and components and/or from the materials of construction of the equipment, protective systems and components. As shot firing can release potentially explosive atmospheres, this document is also applicable to the equipment used for shot firing, apart from the explosives and detonators. This document is applicable to equipment, protective systems and components at all stages of use. This document is not applicable to: — medical devices intended for use in a medical environment; — equipment, protective systems and components where the explosion hazard results exclusively from the presence of explosives or unstable chemical substances; — equipment, protective systems and components where the explosion can result from reaction of substances with oxidising agents other than atmospheric oxygen or by other hazardous reactions or conditions other than atmospheric conditions; — equipment intended for use in domestic and non-commercial environments where explosive atmospheres may only rarely be created and solely as a result of the accidental leakage of fuel gas; — personal protective equipment covered by Regulation (EU) 2016/425; the design and construction of systems containing desired, controlled combustion processes, unless they can act as ignition sources in potentially explosive atmospheres; — mines where firedamp and/or combustible dust are not naturally present and surface installations such as coal preparation plants, power plants, coke oven plants etc. in which an explosive atmosphere can be present, but which are not part of a coal mine. These are covered by EN 1127-1:2019.

Sprogiosios atmosferos. 20-1 dalis. Medžiagų charakteristikos dujoms ir garams klasifikuoti. Bandymo metodai ir duomenys (ISO/IEC DIS 80079-20-1:2026)

This document is published as a dual log standard and provides guidance on classification of gases and vapours. It describes a test method intended for the measurement of the maximum experimental safe gaps (MESG) for gas-air mixtures or vapour-air mixtures under normal conditions of temperature and pressure (20 °C, 101,3 kPa) so as to permit the selection of an appropriate group of equipment. This document also describes a test method intended for use in the determination of the auto-ignition temperature (AIT) of a vapour-air mixture or gas-air mixture at atmospheric pressure, so as to permit the selection of an appropriate temperature class of equipment. Values of chemical properties of materials are provided to assist in the selection of equipment to be used in hazardous areas. Further data may be added as the results of validated tests become available. The materials and the characteristics included in a table (see Annex B) have been selected with particular reference to the use of equipment in hazardous areas. The data in this document have been taken from a number of references which are given in the bibliography. These methods for determining the MESG or the AIT may also be used for gas-air-inert mixtures or vapour-air-inert mixtures. However, data on air-inert mixtures are not tabulated. Keywords: classification of gases and vapours, measurement of the maximum experimental safe gaps (MESG)
