Misuse of products and improper installation may result in the UVC products being unsafe. Always follow the directions laid out in the user manual.
UVC is very well researched and well understood. Compared with UV-A and UV-B, both of which are present in sunlight, UVC presents little penetration into deeper layers of skin. In fact, UVC primarily impacts and is absorbed by the outer dead layer and outer skin. The current daily safe limit for 253.7 exposure over an 8 hour period is 6 mJ/cm2 [American Conference of Governmental Industrial Hygienists. 2020 Threshold Limit Values and Biological Exposure Indices] This compares with 10 minutes of exposure to sunlight with a UV index of 10.
However, exposure to UVC can cause temporary skin and eye irritation/ redness and longer exposure can cause burns. When using ultraviolet disinfection lamps, people, animals, and plants MUST not be in the disinfection area. Objects may exhibit accelerated aging, in a similar way that objects are aged when left in direct sunlight. After using ultraviolet light, the area must be ventilated for at least 10 minutes.
Our products have multiple safety circuits built into all of its products to reduce and avoid the risk of incorrect use resulting in injury.
