Q.Is UV-C harmful to humans?

Prolonged, direct exposure to UV-C light can cause temporary skin redness and eye
irritation, but does not cause skin cancer or cataracts.At no time do germicidal lamps cause
any permanent damage. Ultra-violet (UV) lamps should not be used to disinfect hands
or other areas of your skin
Do not allow prolonged exposure to ultraviolet irradiation and allow for safe operation and
maintenance. If you are exposed to direct germicidal light, it can burn the top surface of your
skin. If your eyes are exposed, it would be similar to a “welder’s flash”, and your eyes can
feel dry or gritty.
