As temperatures climb, a dangerous trend of creating "DIY air conditioning units" using household fans and ice or frozen water bottles is circulating on social media. Experts from Electrical Safety First are warning that these popular "heatwave hacks" could prove fatal, posing a significant risk of electric shock.
Giuseppe Capanna, Product Safety Engineer at Electrical Safety First, cautioned against viral trends seen on platforms like TikTok. "It's not uncommon for these hacks to expose you to the risk of electric shock," he stated. The primary danger arises when melting ice or water comes into contact with a fan's motor, creating a pathway for electricity to shock users.
The consumer safety charity also highlighted other common mistakes people make with fans, particularly during hot weather.
Fan Safety Recommendations
Electrical Safety First advises against leaving fans running overnight. "It may be tempting to keep the cool air flowing as the nights become humid, but households are putting themselves at risk if a fault occurs with their device while they are sleeping," the charity explained. If a fan malfunctions while someone is asleep, their ability to react to a fault is greatly reduced.
For those who find it difficult to sleep without a fan, the experts recommend ensuring a working smoke alarm is present in the home. Additionally, fans should be placed on a flat, stable surface to prevent them from tipping over, and regular cleaning is essential.
Dust buildup in fan vents or the motor can lead to two risks: the motor may be placed under additional strain, and accumulated dust can become a source of ignition if the motor overheats. "Always clean your vents to ensure your fan works efficiently and is kept in good condition," the charity advised. Users should always unplug the fan and follow manufacturer instructions before attempting any cleaning.
Experts also urge consumers to be wary of unusual noises, such as faint buzzing sounds, as these could signal an electrical fault. Wear and tear on the fan itself or its cables should also be monitored.
Purchasing and Usage Guidance
Capanna noted that with rising temperatures, consumers often seek out fans, sometimes being tempted by cheaper versions from social media or online marketplaces. "Safety begins with where you shop and we always advise sticking to reputable high street retailers where you know your product will be made to a high standard," he said.
Consumers are also advised to check if a fan has been recalled by the manufacturer or has developed a fault during its lifespan before purchase and use. Proper fan usage and maintenance are critical for preventing accidents during heatwaves.
