Hazardous Areas Services

Development of the initial step in Hazardous Area Compliance where our team are experienced in the classification of both gas and dust hazardous areas.

Applying the legislation outlined in AS/NZS 60079.10.1,  AS/NZS 60079.10.2 (or other acceptable foreign standards where suitable) our team will provide you with a Hazardous Area Classification Schedule containing a full report, source of release table and flammable goods properties table.

Our technical drafting team can develop Hazardous Area Drawings, showing zonal extents and the classification of the gas and/or dust.

All Hazardous Area Classifications should be reviewed periodically to ensure that the classification still covers the same areas as the initial classification when changes on site may affect zonal extents

Our capabilities can provide a full Hazardous Area electrical design or a third-party design review on your current design

The electrical design will be completed in compliance with the applicable standards, acts, and regulations, including AS/NZS 60079.14, IEC 60079.14 or Euronorms which  incorporate:

  • Equipment and cable selection
  • Cable Schedules and wiring diagrams
  • Maximum Power Dissipation calculations
  • Descriptive System Documents for Intrinsically Safe circuits
  • Verification Dossier development or updating

The Responsible Person or Technical Persons with Executive Function for Hazardous Areas is not included in the Australian and New Zealand Standards; however, it is part of International Standards (IEC) and covered with other foreign schemes as an industry standard and best practice.

Coex Training believes that this competency is a critical part of ensuring that Maintenance programs and Inspection regimes interlink and cover all necessary requirements, outcomes and actions to maintain a safe and compliant installation.

 

Electrical equipment requires selection and installation according to the hazardous area electrical design. The hazardous area installation is an electrical installation and needs to be installed and tested in accordance with AS/NZS 3000 as well as the latest edition of the hazardous area standard AS/NZS 60079.14.

Installation of the equipment needs to be carried out according to any manufacturer’s documentation provided with the equipment and any conditions of Certification.

The hazardous area installation needs to be installed by an electrician with an electrical licence for that State and holding the required competency under the electrotechnical training package.

All test results, manuals, operating directives, installation instructions etc. need to be kept in the Hazardous Area Verification Dossier.

It is mandatory to inspect hazardous area installations prior to being put into service and ongoing inspections throughout the life of the plant.

According to AS/NZS 60079.17 there are three “Grades” of inspection and three “Types” of inspection.

The three Grades are:

  • Visual inspections
  • Close inspections
  • Detailed inspections

The three Types of inspection are:

  • Initial inspection
  • Periodic inspection
  • Sample inspection

Our team is experienced domestically and internationally with classification, design, installation, maintenance, and inspection of electrical installations and equipment in hazardous areas which adds depth to the auditing requirement having dealt with best practices on an international scale.

The hazardous area ESO audit needs to be carried out by an electrical engineer or electrician competent in internal auditing and has been accredited by the ESO to hold office as an auditor.

All documentation provided with the Hazardous Area audit is to be added to the Hazardous Area Verification Dossier.

Where equipment is required that does not have Certification suitable for an Australian installation our team can carry out a Conformity Assessment to determine the suitability and provide a full report on the outcome.

Our team will complete the assessment and provide a full report on conformity, if the report shows that there is an ‘equivalent level of safety’ to the current version of AS/NZS 60079.14 or IEX 60079.14, there will be a positive outcome allowing the equipment to be installed in an Australian installation.

The Verification Dossier is the most important aspect of a hazardous area installation where all relevant documentation for that installation is kept and be comprehensible for anybody to access the required information

Our team can manage the creation, implementation, or ongoing utilization of your site Verification Dossier ensuring compliance with all relative legislation.

Coex has a streamlined Verification Dossier template that aligns with AS/NZS60079.14 and AS/NZS60079.17 ensuring full compliance that can be implemented on your asset.

Due to the nature of the Hazardous Area specialized design and installation, a concise maintenance and inspection program needs to be put in place for safety and compliance.

Full compliance prevents the possibility of a dangerous situation that may give rise to a possible explosion.

With outstanding domestic and international experience, our technical team can work with your specialists and key personnel to develop the required programs to ensure overall Hazards Areas compliance.

Coex Training provides nationally recognized training for the following parts of Hazardous Areas:

  • Hazardous Area awareness
  • Hazardous Area refresher
  • Installation, maintenance testing and Inspection
  • Certificate IV in Hazardous Areas
