Notice to Industry Number 28 Date of Issue: 24 January 2006 Electricity: Residual Current Devices (RCD’s) Occupational Safety and Health Regulation 1996 Regulation 3.60 ‘Protection against earth leakage current when portable equipment in use’ All work places after 31 March 1998 are required to comply with WorkSafe Regulation 3.60 “Protection against earth leakage when portable equipment in use.” This includes vessels that are wired with an unearthed system and fitted with a monitoring device to detect earth faults. In this wiring system the RCD will provide an extra level of safety under a second fault situation. Regulation 3.60 is contained in “Guidance Note ELECTRICITY: Residual Current Devices”, and is available from WorkSafe. WorkSafe Regulation 3.60 does not apply to a workplace at which the supply of electricity :– a) does not exceed 32 volts alternating current b) is direct current c) is provided through an isolating transformer complying with AS/NZS 3108; or; d) is provided from the unearthed outlet of a portable generator. Clause (3) of Regulation 3.60 states that a person having control of a workplace must :(a) Ensure that each non-portable residual current device installed at the workplace is kept in a safe working condition and tested on a regular basis to ensure its continued effective operation; (b) Provide, where electricity is supplied to portable equipment through a fixed socket, protection against earth leakage current by means of :(i) a non-portable residual current device installed at the switchboard; or (ii) a non-portable residual current device built into a fixed socket which, having regard to the primary use of the socket and its location, is likely to be used by a person operating portable equipment; and (c) ensure where a non-portable residual current device has been :– (i) installed at the switchboard, that a notice is displayed in a prominent place at or near the switch board indicating that a non-portable residual current device has been installed at the switchboard; or (ii) built into a fixed socket, that the socket can be identified as providing protection against earth leakage current. Department for Planning and Infrastructure Commercial Vessel Safety Branch 1 Essex Street, PO Box 402, Fremantle, Western Australia 6959 Regulation 3.60 Protection against earth leakage current when portable equipment in use is designed to minimize the risk of a person receiving a harmful or fatal shock when using portable electrical equipment. It is intended that the RCD will provide an extra level of safety, preventing electrocution to persons using portable equipment. The RCD is complementary to the standard protection devices installed on vessels. Owners that feel that their vessels do not require RCD’s should apply to the Worksafe Commissioner (Department of Consumer & Employment Protection, 1260 Hay St, West Perth, WA 6005 Telephone 9327 8889) for an exemption by putting together a detailed submission for each vessel for which they are seeking an exemption. The application for an exemption should contain the following information: 1. Sufficient technical data (electrical drawings) to enable an informed assessment to be made; 2. Such technical data is to be supported by an explanation from a competent person that the installation can not support the installation of RCD's (Residual Current Devices); 3. Vessel details (vessel name, length, material and M&H number). If granted the exemption will apply to that vessel only; and, 4. Details of the operation (passenger numbers, geographical area of operation) 5. For what length of time the vessel will be operating in WA waters Please contact the Commercial Vessel Safety Branch on telephone no: 9216 8240 for further information David Pollard A/Manager Commercial Vessel Safety Branch Department for Planning and Infrastructure Commercial Vessel Safety Branch 1 Essex Street, PO Box 402, Fremantle, Western Australia 6959
