[Thoughts on Channel NewsAsia article]

In the recent article published by Channel NewsAsia, NEA has called for concerns and extra consideration when using ultraviolet-C disinfection devices especially for households.

Ultraviolet (UV-C) sterilisation is one of the most efficient and effective ways of disinfection and is used as a means to kill germs like bacteria and viruses. UVC light can also be used to kill the new coronavirus, SARS-CoV-2. However, it is also the most dangerous type of UV light between - UVA, UVB and UVC.

As such, when getting ultraviolet sterilisers and devices, it is of utmost importance to get sterilisers with all appropriate safety features to protect users from exposure to UV radiation.

Note that all our sterilisers have been cleared by NEA that we have met all their safety guidelines - Refer to email correspondence with NEA.

SINGAPORE: The use of sterilisers based on ultraviolet-C (UVC) radiation technology is not advised for households, said the National Environment Agency (NEA) on Tuesday (Nov 23).

"Many such sterilisers marketed for home use lack safety features that protect users from unintended or accidental exposure to UV radiation.


"To prevent accidental exposure and health risks, members of the public are advised not to purchase any UVC steriliser products that have no safety features," the agency said in a media advisory.

Those who already own such devices should avoid direct skin exposure to UVC radiation and avoid looking directly into the light source.

Consumers should stop using their UVC steriliser immediately if it does not contain any safety engineering features, especially if the product is intended for use on the skin, said NEA.

Since the beginning of the COVID-19 pandemic, UVC disinfection devices have become more available amid an increased demand for such items.

However, NEA advised that UVC-based disinfection should only be applied in industrial or commercial settings with appropriate safety features and safe use practices in order to avoid eye or skin injuries.

Such injuries could include damage to the cornea, with burning sensations and sensitivity to light, as well as burns resulting in redness and peeling of the skin.


What to look out for when buying UVC sterilisers

When purchasing such sterilisers, consumers should only choose those that have safety engineering features that properly contain the UVC sources to prevent exposure to radiation.

Here are some examples provided by NEA:

  • For portable UVC lamps, desk lamps, bulbs or tube lamps: Motion sensors that automatically switch the UVC source off when a person or animal approaches it

  • Fo
