Safety and Disclaimer Notice

This website and publications by the Historical Radio Society of Australia Inc. contain articles, circuitry and advice regarding radios and associated equipment that may be mains-operated.

Electrical Safety is Your Responsibility

Appliances connect to mains voltages operate at lethal levels, and/or generate dangerous voltages and constitute a serious hazard which could result in electrocution.
Any modifications alterations or servicing of Radios and associated equipment must only be attempted by qualified persons. In addition, an isolation transformer must be used at all times when AC/DC or other transformerless appliances are connected to the mains power supply.

Power off and disconnect

Any work carried out on radios and devices should be done with the power turned off and the power plug removed from the wall socket. In the case of devices (including Televisions) with high DC voltages generated internally, a discharge resistor can be carefully used across the DC after switching off, to ensure there is zero volts.

No Voltage is Safe

Additionally all equipment described herein powered from the AC mains can cause electrical shocks of a less severe nature than electrocution. Electrical shocks commonly cause involuntary reflex actions and these reflex actions may result in personal injury. Users of this website are advised to take all reasonable precautions to avoid electrical shock when working on all types of radio equipment.

Electrical Safety Law

Any devices for sale in HRSA sales and Auctions or other outlets like eBay, whether private sales or HRSA sales are required to have an Electrical safety notice attached. In Victoria the prescribed wording is:


Cutting off the cord or plug is not an acceptable alternative.
Some people believe that cutting the mains cord or plug off absolves them of the need to have the above label. Not so. In fact many collectors are highly disappointed if the plug or lead is cut off, as then they have to search for an authentic replacement.

Know the health and safety risks

Some older heatsinking materials, capacitors and internal filling materials used in Radios are known carcinogens. Users of this website or HRSA publications are advised to be aware of hazardous carcinogenic materials and to treat such materials in accordance with Industry Occupational Health and Safety legislation, recommendations and guidelines. Users should, where possible, obtain manufacturers’ instructions relating to safe working practice, and shall observe those instructions.

Worksafe Australia recommendation for the removal of asbestos.

Note a few radios, especially some models nicknamed “Empire State” and Mickey OZ models, contain Asbestos. Even a number of 1950s radios and Radiograms had an Asbestos heat shield.
