  5. Expert Mission on ATEX Implementation Internal Market65344 ATEX Directives 2 Directives applicable in the EU for Explosive Atmospheres (ATmosphéresEXplosibles): ATEX 95 Economic (Product) Directive 94/9/EC, 23-03-1994ADDRESSED at MANUFACTURER ATEX 137 Social (Workplace) Directive 1999/92/EC, 16-12-1999ADDRESSED at USER (Employer)

  6. Expert Mission on ATEX Implementation Internal Market65344 Scope ATEX 95 (Product Directive) • Requirements for Equipment for use in potentially Explosive Atmospheres • Focus on the elimination of trade barriers • Free movement of goods • Creation of level-playing field in EAA • Applicable to all places where explosive atmospheres may occur (ALSO inside equipment and apparatus) • Only equipment and preventive systems that comply with and meet the requirements of ATEX 95 may be brought to the EER market

  7. Expert Mission on ATEX Implementation Internal Market65344 Scope ATEX 137 (Workplace Directive) Scope: • Sets out minimum requirements for the safety and health protection of workers potentially at risk from explosive atmospheres in the workplace • Basically NOT applicable inside equipment and apparatus • OSH Framework Directive requires protection against any risk at the workplace, so also against the consequences of an explosion

  8. Expert Mission on ATEX Implementation Internal Market65344 Aim ATEX 137 Aim and Focus: • Protection of workers’ health and safety at work against explosions • Obligations are addressed at Employers • The quantity of a flammable gas / liquid or solid determines whether a site comes under the jurisdiction of the ATEX-137 Directive • ATEX-137 containsbroaderobligationsthan ATEX-95

  14. RM Verification Process Observations Document review Interviews Workplace Inspection Findings Finding Finding Criteria Documented? Good Moderate Poor Bad Appropriate? Implemented? Assessment + Judgement Conclusions Follow Up: Enforcement?

  15. Documented? Appropriate? Main Questions Are the correct RISKS identified? Are the correct MEASURES implemented? Are measures well MAINTAINED? Is Risk Management System (RMS) appropriate as to effectively control all activities? Is the Prevention Policy of sufficient Quality? Implemented? RM Inspection Verification Questions

  16. Expert Mission on ATEX Implementation Internal Market65344 General Control Measures EXPLOSION PREVENTION General: • Prevention of formation of explosive atmospheres • Avoidance of ignition of explosive atmospheres • Mitigation of the effects of an explosion • All preventive + repressive measures operational as to prevent any further propagation of explosions • Review: All technical and organizational measures must be reviewed regularly and in any case after significant changes

  17. Expert Mission on ATEX Implementation Internal Market65344 General Control Measures EXPLOSION PREVENTION General: • Safe design: Safe design of workplaces, also in relation to Explosion Hazards • Safe work: Work can be performed safely at places with explosive atmospheres • Supervision: sufficient and effective • Classification: Hazardous areas to be classified and indicated • Coordination and Cooperation

  18. Expert Mission on ATEX Implementation Internal Market65344 Specific Control Measures EXPLOSION PREVENTION Specific: • Safe discharge of hazardous substances • Equipment and protective systems for use in explosive atmospheres meets requirements of ATEX 95 (in EPD) • Equipment requirements: • Hazardous zone 0 of 20: category 1 equipment • Hazardous zone 1 of 21: category 1 of 2 equipment • Hazardous zone 2 of 22: category1, 2 of 3 equipment

  19.
