Survey of approved explosion-protected electrical apparatus

A survey of approved explosion-protected electrical plant in-use hazardous zones of NSW mines was completed in late 2007. The result of the survey revealed that over 60% of existing approvals are NO LONGER USED in NSW coal mine hazardous zones, these approvals have subsequently been removed from the current list.

The revised list of approved explosion-protected electrical plant is available above for immediate review and is to be used as the list nominated in the Gazette notice "Types of electrical plant used in hazard zones".It would be appropriate to review the approvals list against current plant assets at your mine and notify Paul de Gruchy (paul.degruchy@dpi.nsw.gov.au) of concerns and/or deficiencies in the list.

It should also be noted, it is the Department's objective that all electrical explosion-protected plant used in coal mine hazardous zones have a valid Certificate of Conformity as stipulated in the gazette notice.

The following survey of approved explosion-protected electrical apparatus in-use within a hazardous zone of NSW underground coal workplaces was published mid-2007 and was circulated to end-users, plant hire companies and other interested parties.
The original survey aimed to cull items from the current approvals list that were not being used, thus minimise the impact to the industry, but allowing a concentration of resources for the ongoing supervision of plant that is of importance.
