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
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
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
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
Expert Mission on ATEX Implementation Internal Market65344 Specific Control Measures EXPLOSION PREVENTION SPECIFIC • Exchange of wrong ATEX equipment be prevented • Special protective clothing for workers in areas with possible explosive atmospheres • An alarm / warning system must be installed and in operation • After a change (MoC) and/or maintenance of equipment in areas with explosion risks an initial check should be carried out by qualified person before the installation is put into operation again
Expert Mission on ATEX Implementation Internal Market65344 Specific Control Measures EXPLOSION PREVENTION Specific: • Work Instructions: in writing • Approval of work before start of the it: • Work permit system must be in operation • Equipment must be fail-safe in case of power interruption • Emergency and/or escape equipment provided to workers • Authorized persons may only switch off equipment
Expert Mission on ATEX Implementation Internal Market65344 EXPLOSION PROTECTION DOCUMENT (EPD) Minimum required CONTENT: • Identification of Explosion Hazards at all workplaces • Identification of Ignition Sources at all workplaces • Assessment of Explosion Risks • Classification of Hazardous Zones • zone 0, 1 or 2 for Gas / zone 20, 21 or 22 for Dust • Description of design, construction, operation and maintenance of workplaces, work equipment, process installations and warning devices • Description of preventive and repressive control measures as to Prevent, Eliminate or Reduce / Mitigate the (consequences of) explosion • Description of system for cooperation and coordination of work in areas with explosion risks, e.g. work permit system • Way of training of workers regarding Explosive Risks
Expert Mission on ATEX Implementation Internal Market65344 Identification of Explosion Hazards + Assessment of Explosion Risks (in EPD) RISK: in general R = P x E Other: Risk Graph / Fine & Kiney When assessing explosion risks, take into account: • Likelihood that explosive atmospheres will occur and their persistence • Likelihood that ignition sources, including electrostatic discharges, will be present and become active and effective, • Possible interactions between substances in use, processes and installations • Scale of the anticipated effects (Consequences).
