Scope:

This European Standard gives general guidelines 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
- hazard identification;
- risk assessment;
- elimination or minimization of risk;
- information for use.
The safety of equipment, protective systems, and components can be achieved, as described in EN 292-2:1991, by removal of hazards and/or limiting the risk, i.e.
a) by risk reduction by design;
b) by safeguarding;
c) by information for use;
d) by additional precautions.
NOTE Risk reduction by design in accordance with clause 3 of EN 292-2:1991 should not be confused with the concept of ""design"" as described in 6.5 of this standard.
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 clause 6 of EN 292 2:1991.
The preventive and protective measures described in this European Standard will not provide the required l ...
