7 Summer Electrical Safety Tips for Sydney Businesses

Summer in Sydney is perfect for beach days, but it can be tough on overloaded power boards and hot switchboards. As the year wraps up and your team gets ready for a break, now is a great time to boost your electrical safety and finish important checks.

Key takeaways

• Summer increases electrical risks in Sydney workplaces thanks to heatwaves, storms, extra appliances and shutdowns.
• A simple pre-holiday electrical safety checklist helps you spot damaged leads, overloaded power boards and faulty safety switches before you lock up.
• RCDs (safety switches) and up-to-date test & tag are critical controls for shock and fire risks.
• Unplugging non-essential gear and planning for heatwaves and storms reduces the chance of issues while the building is empty.
• Booking a pre-holiday test and tag in Sydney means you start the new year with safer equipment and clearer compliance.

Why does summer increase electrical safety risks?

Sydney summers mean heatwaves, afternoon storms, and a busy end-of-year period. These conditions can quietly raise electrical risks at your workplace:

• Heat and humidity can stress electrical equipment, increasing the chance of failure and fire.
• Storms and power fluctuations can damage sensitive electronics and worsen existing faults.
• Temporary gear like extra fans, portable air conditioners, Christmas lights, and extension leads often get plugged in wherever there is a spare outlet.
• Reduced staffing over the break means faults may go unnoticed for longer.

Under WHS law, anyone running a business (a PCBU) must manage electrical risks and keep workers and visitors safe, including by inspecting and testing equipment where appropriate.

Summer is when these responsibilities are most likely to be put to the test.

Your pre-holiday electrical safety checklist in Sydney

Follow this step-by-step checklist in the weeks before your shutdown. It works well for offices, warehouses, retail, hospitality, gyms, clinics, and light industrial sites across Sydney.

    1. Map out your shutdown and “always-on” equipment

Start with a quick stocktake:

• List areas that will be fully shut down (e.g., offices and meeting rooms).
• List equipment that must stay on (e.g. servers, security systems, fridges, essential plant).
• Identify who is responsible for doing the final walk-through on the last day.

This helps make sure equipment is not left on by mistake and keeps attention on high-risk and important gear.

     2. Walk the floor and look for obvious electrical hazards

Do a simple visual inspection of your workplace:

• Leads and cords

  Look for cuts, fraying, kinks, crushed or pinched sections, and exposed inner wires.

• Power boards

  Check they’re not overloaded, dusty, or daisy-chained (one power board plugged into another).

• Sockets and switches

  Look for discolouration, cracking, or signs of burning.

• Portable equipment

  Inspect tools, chargers, kettles, fans, vacuums and other appliances for damage.

If something looks damaged, feels loose, or has been “dodgily repaired” with tape, take it out of service right away and tag it “Do Not Use” until it is tested or fixed. This follows Safe Work Australia’s advice on managing electrical risks at work.

    3. Check your safety switches (RCDs)

Residual Current Devices (RCDs), often called safety switches, are designed to cut power quickly if they detect a fault, reducing the risk of electric shock.

How to Test Your RCDs Before the Holidays

• Locate your safety switches in the switchboard.
• Use the “Test” button to confirm each one trips as expected.
• Reset them and make a note of any that trip more than once. Flag these for an electrician or your test and tag technician.

Regular RCD testing is a key part of workplace electrical safety and is covered in standards like AS/NZS 3760:2022, which sets out how electrical equipment and RCDs should be inspected and tested in service.

    4. Confirm your test and tag is up to date

Electrical testing and tagging checks that portable appliances and leads are safe to use and clearly labelled with a test date and retest due date.

Key Areas to Prioritise for Test & Tag

• Walk through high-risk areas (workshops, kitchens, production areas, warehouses).
• Check tags on leads, tools and appliances – are any out of date or missing?
• Prioritise equipment used by multiple people or the public (e.g. shared tools, café equipment, gym gear).

AS/NZS 3760 recommends different testing intervals based on your environment. For example, workshops and construction areas need more frequent testing than low-risk offices.

If your tags are out of date, or you’re not sure when things were last checked, a pre-holiday test and tag visit is a smart move.

    5. Unplug and tidy non-essential equipment

A simple but powerful risk-reducer:

• Unplug non-essential appliances at the wall: monitors, chargers, fans, printers, radios, and bench-top appliances.
• Turn off and unplug seasonal items, such as Christmas lights and decorations.
• Coil and store spare leads and power boards neatly so they’re not left underfoot or under furniture.

Having less equipment powered on during the break lowers the risk of faults, overheating, or electrical fires, especially during heatwaves or storms when buildings might be empty.

    6. Prepare for heatwaves and storms

Sydney’s summer brings hot, humid days and afternoon storms, which can be hard on both people and equipment. SafeWork NSW and Safe Work Australia both highlight the need to plan for extreme heat and its effects on workplaces.

Heat and Storm Protection Checklist

• Surge protection for sensitive equipment such as servers, POS systems, and specialist machinery.
• Keeping switchboards, server rooms and plant areas well-ventilated and free of clutter.
• Ensuring gutters and drains are clear to reduce the risk of water ingress near electrical installations.

If you’re closing completely, make sure someone is nominated to respond if alarms trip, power is lost, or a storm causes damage.

    7. Document what you’ve done

Finally, keep a simple record of:

• The date of your pre-holiday electrical safety check.
• Any faults found and how they were addressed.
• Details of your latest test and tag visit and next due dates.

Keeping clear records helps you meet your WHS duties as a PCBU and makes things easier during audits, insurance questions, or if an incident happens.

Why book a test and tag before the break?

A professional test and tag service goes beyond a quick visual check. Technicians use calibrated equipment to measure insulation resistance, earth continuity, polarity and more, in line with AS/NZS 3760.
