Electrical switchboard panels and meter panels containing asbestos
This information bulletin was developed to assist industry, electrical contractors and electricians with the compliance requirements in the modification, maintenance or repair of electrical switchboards and meter panels, and the hazards associated with older panels.
Hazards associated with older electrical switchboard panels and meter panels containing asbestos
An asbestos hazard exists for electrical contractors and electrical workers carrying out alterations or additions to older electrical switchboard panels and meter panels manufactured from an asbestos/resin or asbestos/coal tar pitch composite.
The panels are usually a dark brown or black colour, have a rough fibrous or wood like surface finish and may have a strong tar smell about them.
Brand names such as Lebah, Zelemite, Miscolite and Ausbestos may be stamped on the rear of the panels.
Electrical contractors and workers should be aware that drilling, cutting, sanding or water blasting these panels may release harmful asbestos fibres. Meter boxes fitted with such panels may contain loose (friable) asbestos fibres.
Where possible panels containing asbestos should be replaced with modern materials available from electrical wholesalers.
Any modification, maintenance or repair* on a metering panel at the customer’s request will require replacement of asbestos type panelling in accordance with Power and Water Corporation NP010 Meter Manual – Clause 4.10
* Modification, maintenance or repair includes where a meter isolator is required to be installed due to failures associated with the service fuse.
If drilling, cutting, sanding works etc is to be undertaken on asbestos panels then a risk assessment and asbestos management plan must be prepared. Refer to the resources below for guidance. Both are available from the NT WorkSafe website.
