Hazardous Area Verification
Dossier – HAVD
The Lithium Oil & Gas Australian based quality assurance team can build a compliant hazardous area verification dossier for your facility or complete an audit of your current dossier to ensure it meets all the mandated compliance requirements. Our consultants also deliver training to staff on systems to allow them to easily manage the verification dossier into the future.
Why Do I Need a Hazardous Area Verification Dossier?
The verification dossier is a compliance management tool. In a Hazardous area it is necessary to ensure that any installation complies with the relevant equipment certificates and with the required Australian and international standards and any other requirements specific to the plant in which the installation takes place. To ensure this and the ongoing safety and compliance of a hazardous area, it is a requirement that all sites compile and maintain a hazardous area verification dossier that outlines the compliance of the facility and its equipment. This document, known as the Verification Dossier or Site Dossier, contains all the information relating to their hazardous area and the equipment installed within. The verification dossier can be kept as hard copy, soft copy or a combination of the two.
What Documents Must My Dossier Contain?
The hazardous area verification dossier should include the following items where applicable:
- The area classification drawings and any associated documents, including details of gas groups and temperature classes present. For dust installations, resistivity, layer and cloud ignition temperatures of the type of dust present.
- External influences such as ambient temperature, corrosion resistance etc.
- Optional assessment of consequences of ignition.
- Instructions for erection and connection of installations and equipment in the hazardous areas.
- Copies of the certificates of conformity for all items of electrical equipment installed in the hazardous areas.
- Details of any uncertified or foreign certified equipment and justification for its use (and/or Conformity Assessment Documents stating that the equipment is designed and manufactured to assure an equivalent level of safety that is required by ANZ or IEC certification).
- Reference to any special conditions of use in the certification documents with suffix X.
- Details of calculations performed to verify compliance (e.g. Ex e temperature rise and Ex i entity calculations)
- Records of electrical tests performed on installation and commissioning.

- Records of overhauls and repairs carried out by licensed repairers.
- Records of any modifications made to equipment, including the justification for them.
