This European Standard 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 European Standard 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 flammable 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 European Standard 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 standard, measures according to c) against explosions are dealt with in clause 7 of this standard. Mea¬sures in accordance with d) are not described in this European Standard. They are dealt with in EN ISO 12100:2010, clause 6. The preventive and protective measures described in this European Standard will not provide the required level of safety 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 standard is applicable to any e ...
