Treat standing water near outlets, electrical equipment, cords or building wiring as unsafe. Keep people and pets out, do not touch affected equipment, and only isolate power if the switchboard is dry and it is safe to do so. Arrange an electrician to assess water-affected electrical systems before use.
What should you do if floodwater reaches electrical equipment?
- Keep clear of the water. Do not enter, touch appliances, pick up cords or reset breakers.
- Keep others away. Prevent children, pets and visitors from entering the affected area.
- Only turn off power if it is safe. Do not approach a wet switchboard or stand on a wet surface to reach it.
- Call for qualified help. A water-affected electrical system needs assessment before it is re-energised or used.
- Begin restoration only after safety clearance. Extraction and drying equipment should be set up to suit a safe site.
Standing-water electrical safety chart
| Situation | Immediate response | Next step |
|---|---|---|
| Water near an outlet, extension lead or appliance | Keep out and do not touch equipment. | Arrange electrical assessment before use. |
| Wet floor with unknown electrical status | Restrict access; do not enter to investigate. | Seek emergency or electrical advice as appropriate. |
| Water-damaged switchboard or tripped safety switch | Do not reset or handle it if wet or unsafe to reach. | Have a qualified electrician check the system. |
| Area confirmed electrically safe | Document the water damage and plan extraction. | Assess hidden moisture and begin controlled drying. |
Why visible water is not the only issue
Water can enter wall linings, floor cavities and areas around electrical wiring without being obvious on the surface. Appliances, power points, cabling and switchboards that have been affected may need professional assessment. Do not assume an item is safe just because it looks dry or its circuit has not tripped.
Official electrical safety advice after an emergency
WorkSafe New Zealand advises turning off power at the mains if this can be done safely and having an electrician check water-affected wiring before the power is turned on again. Follow emergency-service and electricity-network instructions where they apply.
When flood restoration can begin
Once the area is safe to access, a restoration assessment can identify water removal, cleaning, moisture inspection, equipment placement and monitoring needs. Read our emergency carpet-drying action plan for the next practical steps after safety has been addressed.
Frequently asked questions
Can I use a wet vacuum near a flooded power point?
Do not use equipment in an area with an unknown electrical status. Keep out and arrange qualified assessment first.
Should I reset a tripped safety switch after a flood?
No. If water may have affected electrical wiring or equipment, do not reset breakers or safety switches until an electrician has checked the system.
Can I turn on a water-damaged appliance once the floor is dry?
Not without appropriate assessment. Dry-looking equipment can still have water damage that creates a safety risk.
When can drying equipment be installed?
After the affected area has been assessed as safe for access and electrical equipment. Placement should follow the site’s restoration plan.
