A Microbial UVC Disinfection Casket

The COVID-19 infection has spread worldwide through various sources in human beings. It was very difficult to find the infected items. So as a precautionary measure, the outsourced items like food, grocery items, medicine, masks, etc. were disinfected prior to use. Ultraviolet (UV) light is a form of light that is invisible to the human eye, having wavelengths roughly between 200 and 300 nanometers. The UV light-based devices have exploited the market based on the disinfecting property of UV light. With this finding, UV irradiation has been found to kill or inhibit the growth of many microbes (including bacteria, viruses, fungi, and protozoa) which are known to cause disease in humans and animals. UV light with a wavelength of approximately 250 to 260 nm provides the highest germicidal effectiveness. UV light has also been utilized to disinfect the surfaces of packages. A wrapped or enveloped product is subjected to a UV light source to control potential contamination on the surface of the packaging. A problem occurs when the package has surfaces that require disinfection, but these surfaces do not face the UV lamp as the package passes the UV lamp. Additional passes under the UV lamp must be made to illuminate the other surfaces of the package. This single surface disinfection may be acceptable for flat, roughly two-sided packaging, but is typically not acceptable for multi-sided packages. To disinfect such products, A Microbial UVC disinfection casket has been developed by CSIR-NPL, New Delhi, in collaboration with M/s Motras Scientific Instruments Pvt Ltd, Manesar, Gurugram,Haryana. The system has been validated for a UVC wavelength of 254 and an intensity of 13 J/m² for the estimation of time for germicidal disinfection. The casket has also been tested for ozone formation, and it was found within the permissible limit. This system will be highly useful to disinfect non-porous surfaces.

To disinfect non-porous surfaces like food packets, grocery items, medicine, masks, mobile, wallet, surgical items, etc, prior to use using UVC light.
