How is health risk mitigated when using UV light?
Using UV-C light for disinfection and sterilization is an effective approach to eliminating airborne pathogens. But while UV-C light kills pathogens, there is also the potential for health risks to humans, particularly related to the eyes and exposure to ozone.
When UV-C light hits the eyes directly, it can cause damage to the cornea and conjunctiva. This risk is particularly present if UV radiation is not properly limited or if exposure occurs over a long period of time. To prevent this, protective mechanisms are required to ensure that UV radiation remains within safe limits.
Another potential health risk associated with UV light is the formation of ozone. Ozone can irritate the respiratory tract and cause inflammation, especially when inhaled in high concentrations. For this reason, it is important to ensure that the UV lamps used do not cause ozone formation.
In order to minimize these health risks, manufacturers such as those of UVC SterilVentilation high-performance low-pressure lamps from Germany use special lamps that only emit light with a wavelength of around 254 nm. This value is above the range in which ozone is formed, meaning that the risk of ozone formation is eliminated.
In addition, there are strict standards and guidelines that set the maximum radiation intensity outside the devices to ensure that exposure is safe for humans. DIN ISO 15858 specifies such limit values and ensures that UV-C lamps are only operated under certain conditions to ensure safety.
Another important aspect is changing the UV-C lamps after a certain period of operation, typically after a few thousand hours. This ensures that disinfection efficiency is maintained and the risk of overexposure is reduced. Manufacturers such as novoflow have integrated mechanisms that minimize the risk to people when changing lamps, such as a switch on the housing that cuts off the power supply as soon as the housing is opened.
Overall, when using UV-C light for air disinfection, it is crucial that all necessary safety measures are taken to minimize the risk to the health of users. By adhering to standards, using special lamps and implementing safety precautions, the benefits of UV disinfection can be maximized without endangering health.
