When Two Appliances Are Not in Use, Remember to Unplug Them! Risk of Total Failure or Fire — Many People Don’t Know

Vacuum cleaners are essential cleaning tools in many households due to their ability to efficiently remove dust and dust mites, along with various attachments for different surfaces. However, recent reports have highlighted cases where prolonged plug-in usage or improper handling has led to equipment failure and even severe fires. A housewife in the UK lost her entire home after such an incident and is now urging the public: "Always unplug appliances when not in use." In response, Taiwan Power Company (Taipower) specifically advises disconnecting power for appliances like dehumidifiers and those with standby functions when away or unused. Proper usage habits ensure both electrical safety and extended appliance lifespan.

Can a vacuum cleaner catch fire even when turned off? UK woman’s home burns down after leaving plug in

Warning: Unplug idle appliances immediately

According to foreign media outlet THE Sun, 36-year-old UK housewife Tanya Bennett from Telford, Shropshire, shared her personal experience on TikTok. While she was at work, a sudden fire broke out at her home. Neighbors quickly alerted emergency services, and although she and her pets escaped unharmed, the house was almost completely destroyed—only the kitchen survived.

Tanya revealed that although the vacuum cleaner was not operating at the time, its plug had remained connected to the power source for 18 consecutive hours. Preliminary assessments by fire authorities concluded that prolonged power supply caused an internal electrical fault in the vacuum, triggering the fire. Now homeless and forced to board her pets with friends, Tanya issued a heartfelt plea: "Do not leave your vacuum cleaner plugged in for long periods. The losses from this accident are unimaginable."

Should you unplug appliances when not in use? Online debate sparks concern over hidden 'dust conductivity' hazard

Should we unplug appliances when not in use? A user raised this question on PTT, wondering if their family’s habit of unplugging the TV after watching truly saves electricity. Opinions were divided: some argued that frequent plugging/unplugging damages sockets, while others pointed out: "In older homes, it’s better to unplug—fire risk from wiring," and "Unplugging prevents dust conductivity."

In response to public concerns, Taipower provided the following analysis and recommendations:

• Unplug standby-function appliances to save energy: Devices that display time, have a red light on when off, or can be remotely controlled consume standby power. Unplugging them during long periods of non-use saves electricity. If frequent plugging/unplugging worries you, consider using extension cords with independent switches and automatic overload cutoff features.

• Beware of fire risks from 'dust conductivity': Even when switched off, if dust, hair, or moisture accumulates between plug contacts, it may form a conductive path. This phenomenon won’t trip circuit breakers and can silently lead to fires. Always unplug appliances during long absences or travel.

Three appliances not recommended for frequent unplugging:

Japanese media FINANCIAL FIELD warns that refrigerators, Wi-Fi routers/set-top boxes, and microwaves should not be frequently powered off, as it may disrupt normal operation or cause malfunctions.

Not just vacuum cleaners! Taipower reminds users to turn off and unplug dehumidifiers before sleeping or leaving home

Besides vacuum cleaners, dehumidifiers are another common household appliance requiring attention for electrical safety. Taipower provides specific usage and maintenance guidelines on its official website:

1. Check for safety certification and recall notices: Purchase only appliances with recognized safety marks. Visit the Bureau of Standards, Metrology and Inspection (BSMI) website to verify if a model has been recalled. Immediately stop using and repair any listed units.

2. Cut power when unattended: Use dehumidifiers only when someone is present. Always turn off and unplug before sleeping or going out.

3. Ensure ventilation and safe placement: Place the unit on a level, well-ventilated surface. Avoid enclosed spaces like closets. Never block air outlets with clothing during operation.

4. Regular maintenance and professional repairs: Clean filters regularly to maintain performance. If malfunction occurs, send it only to authorized service centers—never attempt self-repairs.
