Here few answers to UV-C FAQ we had encountered thus far. If you do not find an answer to your question, please get in touch with us and we will be happy to address your query.
Can I use UVC lamps in my home?
Yes – ultraviolet lamps are used in homes, as well as in hospitals, laboratories, clean rooms, doctors″ offices, commercial buildings, food processing plants and other commercial and residential environments throughout the world – any place a concern for clean air exists.
Will germicidal UV take care of mould? UV-C FAQ
Yes. Germicidal UVC lamps will kill up to 99.9% of mould and help prevent future mould growth.
How often do the lamps need to be replaced? UV-C FAQ
Our germicidal UVC lamps are good for approximately 8,000 hours of continuous use.
Should UVC lamps be cleaned? UV-C FAQ
Yes – depending on the surrounding environment, UVC lamps should be checked periodically (approximately every three months), and can be cleaned with a dry cotton cloth or paper towel. Wear rubber gloves and clean with alcohol only. This will also help maximise lamp life.
How much intensity do I need to kill certain organisms?
The exposure of germicidal ultraviolet is the product of time and intensity. High intensities for a short period and low intensities for a long period are fundamentally equal in lethal action on bacteria. The inverse square law applies to germicidal ultraviolet as it does to light: the killing power decreases as the distance from the lamps increases. The average bacterium will be killed in ten seconds at a distance of 15cm from the UVC lamp.
How do germicidal lamps kill?
Ultraviolet light in the germicidal wavelength – 185-254 nanometers – renders the organisms sterile. When organisms can no longer reproduce, they die.
How hot do the lamps get?
Germicidal UVC lamps do not produce much heat – about the same as fluorescent lamps.
What damage will the lamps do to me?
Prolonged, direct exposure to UVC light can cause temporary skin redness and eye irritation, but does not cause skin cancer or cataracts. Do not allow 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. At no time do germicidal lamps cause any permanent damage.
What effects does UV light have on surrounding materials?
Long-term exposure of germicidal UVC light to plastics will shorten the shelf life of the plastic by approximately 10%. Example: If the plastic would normally last about ten years, and it’s exposed to germicidal UVC light the entire time, it would probably need to be replaced in 9 years. Plant life may be damaged by direct, or reflected, germicidal ultraviolet rays. Transient dyes and colors may be faded from prolonged exposure to ultraviolet rays.
Can germicidal UVC penetrate surfaces or substances?
No – germicidal UVC sterilises only what it comes in contact with.
How do you determine disinfection time required?
Refer to the following guide to determine recommended disinfection time.
What safety precautions should be taken when using germicidal UVC?
Avoid exposure to UVC light. Leave the room whilst the disinfection process takes place. Operate lamp via supplied remote control.
