On completion of this course delegates will have knowledge of achieving and maintaining safety in those workplaces containing potentially explosive atmospheres in the presence of non-electrical equipment ignition sources. EU and UK legislation is covered including personal and corporate responsibilities. The course content is intended for those personnel responsible for carrying out activities involving installation, inspection and maintenance of mechanical (non-electrical) ignition-capable equipment located in hazardous areas. Prior knowledge is not required as the course includes the information necessary for those less experienced in the subject.

Session 1 - Hazardous Area Fundamentals (1/2 Day)

  • Definition of hazardous areas / explosive atmospheres.
  • Zone classifications (gas/vapour & dust: BSEN 60079-10-1 & BSEN 60079-10-2).
  • Properties of combustion / fire / explosion.
  • Electrical protection concepts and applicable standards (BSEN 60079 series).
  • Mechanical protection concepts and applicable standards (BSEN 13463 series).

Introduction to ATEX / DSEAR (1/4 Day)

  • Introduction to the ATEX directives and key dates of implementation.
  • Why the ATEX directives exist.
  • Implementation and enforcement.
  • ATEX 100a: Equipment directive – 94/9EC: application to mechanical equipment.
  • ATEX 137: Use directive – 1999/92/EC.
  • DSEAR Regulations (responsibilities: operator, designer, contractor, employee).

Session 2 - Practical Mechanical Aspects of ATEX / DSEAR (1/4 Day)

  • Definition of non-electrical ignition sources (as defined in BSEN 1127)
  • Examples of potential ignition sources in non-electrical equipment
  • Examples of potential ignition sources presented by people
  • Assessment of non-electrical ignition sources (BSEN13463)
  • Maintenance / inspection of non-electrical equipment in hazardous areas

Delegate exercises: (1/2 Day)

  • Hazard perception (release / ignition hazards, escalation)
  • Equipment maintenance: pump bush failure (repair, replacement, alternative materials)
  • Ignition hazard assessment (pump, valve, tank mixer)
  • Example permit to work planning and completion (ethanol tank mixer, simultaneous operations: 2 groups with enforced alternative options)
  • Each session includes a multiple choice questionnaire on completion
