Hazardous Area Definitions

 

INSPECTION

 ‘ An action comprising careful scrutiny of an item carried out either without dismantling or with partial dismantling as required, supplemented by means such as measurements, in order to arrive at a reliable conclusion as to the condition of an item’.

It is a requirement of the Australian Standards that an initial inspection be performed on plant or equipment before being brought into service.

Moving forward from the initial inspection, regular periodic inspections must be established to minimize the risk of explosion protected electrical apparatus acting as a source of ignition.

Adding to that, every plant is different, and so to the grade of inspection and the interval between periodic inspections should be determined taking account of the type of apparatus, manufacture’s guidelines, factors governing its deterioration, the Zone of use and the results of previous inspections.

EMI is often called upon to put in place, oversee or act as a third party in relation to the frequency, types and grades of inspections that best suits our clients, and their plant’s needs.

VERIFICATION DOSSIER

 ‘Set of documents showing the compliance of electrical equipment and installations’.

A Hazardous Area Verification Dossier (HAVD) must be compiled for any electrical installation in a Hazardous Area.
This document must remain on site, and is constantly up dated when any maintenance, repairs, replacement or alterations occur. In conjunction, EMI compiles the Verification Dossier throughout the inspection process. 
With our vast experience in the hazardous area industry, EMI is regularly called upon by our clients to perform audits and inspections across a wide range of industries including the Gas, Petro-chemical, Oil, Pharmaceutical, Food, Steel and Waste Water industries.
In conjunction, EMI compiles the Verification Dossier throughout the inspection process.

 

CONFORMANCE ASSESSMENT DOCUMENT (C.A.D)

 A Conformity Assessment Document is produced to provide evidence that a certificate to an alternative standard can be demonstrated to provide an equivalent level of safety to AS/NZS or IEC Standards. This would normally involve a comparison of the relevant standards and verification that testing has been conducted by a third party.
