6 Ceiling spaces One of our key priority areas: Working safely in ceiling spaces

7 Ceiling spaces Wiring systems in ceiling spaces Before entering a ceiling space always turn off the power at the switchboard. Conduct a pre-work risk assessment. Turning off the power at the switchboard does not turn off all electricity. There may be other sources of supply such as: PV Consumer mains Illegal wiring Identify the location of electrical equipment and cables. 7

8 Ceiling space dangers Hazards in ceiling spaces can include: Wiring subject to mechanical damage Crossing nail plates or other metal work without protection Crossing hanging beams or ceiling joists without protection Exposed conductors above light fittings Damaged or perished wiring Thermal insulation Other hazards Confined area Increase use of services: air-con; communication; security; plumbing; solar PV 8

9 Ceiling space safety tips Ensure any ceiling insulation is not installed over downlights due to an increased risk of fire. Add a reminder sticker to your manhole and switchboard so you remember to switch off all the power before you enter a ceiling space. You can order a Stay safer up there, switch off down here brochure and sticker via 9

10 Solar power systems

11 Solar (PV) Power Systems - Maintenance Like your car, solar PV systems need to be regularly maintained. This is to keep your solar power system functioning safely. Verify cleanliness and check for shading of the array at least quarterly and check for physical defects at least annually. Have an electrical contractor test your solar PV electrical installation at least annually. Follow Manufacturer s Instructions Ensure emergency procedures for shut down and isolation are clearly displayed Ensure unimpeded access to isolator switches Refer to Managing the risk of falls Code of Practice available on our website 11

12 Solar PV Systems - DC Isolator Recalls DC Isolator Brand AVANCO PVPOWER GEN3 or SPM NHP ISO-MAX 12

13 Isolating solar electricity Remember when power is off solar PV can still be generating electricity. Always follow correct shutdown procedures. Shutdown procedures should be located at the inverter and/ or main switchboard.

14 Working near power lines

15 Working near power lines Always stay a safe distance from power lines A safe distance is generally 3 metres, but could be up to 8 metres depending on the voltage of the power line. Avoid trimming trees or branches near power lines. Always use a professional arborist or tree pruning specialist who is trained to do this work. While painting or performing maintenance work stay clear of power lines, including the service line connected to your property. Avoid moving loads under power lines. Look up and live Care must also be taken when digging within the vicinity of underground electric lines. Ring the free Dial Before You Dig service on 1100 or visit 1100.com.au. 15

17 Safety switches Safety Switches save lives. Test yours every three months. 17

18 Safety switches Requirements Safety switches and the Wiring Rules Transfer of property Electrical installation work - domestic houses Ceiling spaces (including electrically conductive ceiling insulation) Rental properties - common question 18

19 Safety switches Common question Question. What are the requirements to have a safety switch and interval testing times for the safety switch in a rental property? Answer. Where a residential tenancy agreement exists, the landlord must ensure an approved safety switch is installed for the general purpose socket-outlet circuit. There is no prescribed inspection and test interval for the safety switch/switches installed at the domestic residence. (The ESO would recommend following the manufacturer s instructions which are generally a three month push button test) 19

20 Sourcing electrical equipment 20

21 Sourcing electrical equipment some tips Buy the equipment from a reputable seller, is it a reputable brand name? Do they have technical back up and expertise? Do they invest in research and development? Have they ensured the equipment is suitable for Queensland conditions? Check the electrical equipment safety system (EESS) national database to see if the importer as has registered themselves and their equipment Check the brand and model match the details on the EESS database and the equipment is marked with the RCM Check there is independent assessment of the claims of compliance by any overseas manufacturer can they show they meet Australian safety standards 21

22 Sourcing electrical equipment (cont d) Don t just buy on price or convenience Do your research on the companies importing and selling the equipment. Regulatory Compliance Mark (RCM): 22
