Have you ever purchased a UV sterilizer online in pursuit of a "germ-free life"? Beware – what you believe to be a health guardian might actually be harming you silently.
Recently, multiple Southeast Asian countries have raised alarms about ultraviolet disinfection products. Singapore's National Environment Agency (NEA) issued a warning urging consumers to exercise caution when purchasing uncertified UVC sterilization products and to avoid using them at home. What's behind this warning, and how can we protect ourselves?
UVC Sterilization: A Double-Edged Sword
The principle of UVC sterilization is straightforward: short-wave ultraviolet light damages the DNA and RNA of microorganisms, effectively killing them. While this technology is widely used in medical and industrial settings, improper use can pose serious health risks.
Imagine exposing your skin and eyes directly to intense ultraviolet light. The consequences range from corneal damage and skin burns to accelerated skin aging and even increased risk of skin cancer. This is why the NEA emphasizes that UVC sterilization devices should primarily be used in industrial or commercial environments with proper safety measures.
Household UVC Products: Hidden Risks
During the pandemic, various household UVC sterilization products flooded the market, from phone sanitizers to surface disinfection wands. However, many of these products lack essential safety features, creating potential health hazards for consumers.
The NEA points out that many portable, tube-style, or desktop UVC products don't include motion sensors. This means the bulbs won't automatically turn off when people approach, exposing users and bystanders to harmful UVC radiation. Additionally, some handheld sterilizers lack gravity sensors, failing to deactivate when pointed upward.
How to Use UVC Products Safely
If you must use UVC sterilization products, always choose models with proper safety features. Look for devices with motion sensors that automatically shut off when detecting movement, or handheld units with gravity sensors that deactivate when tilted upward.
Most importantly, always follow operating instructions carefully. Avoid direct skin exposure to UVC radiation and never look directly at UVC light sources. Even certified products require cautious handling – never take safety for granted.
E-commerce Platforms Take Action
Facing these safety concerns, major e-commerce platforms have begun removing hazardous UVC products. Platforms including Amazon, Carousell, ezbuy, Qoo10, and Shopee have reportedly taken down approximately 8,000 unsafe UVC sterilizers.
While this represents progress, consumers must remain vigilant when purchasing and using UVC sterilization products. When it comes to health, caution always trumps convenience.
Final Warning: If you own a UVC sterilizer without proper safety features, stop using it immediately. Your family's health depends on taking UVC safety seriously.
