Many industries are choosing to use ultraviolet light to kill potentially harmful bacteria. Using UV light to sanitize surfaces and objects is safer and more efficient than using chemicals. For example, hospital workers are constantly at risk of exposing themselves to harmful toxins and suffering from burns whenever they use chemicals. Hand-washing helps, but having workers wash their hands every time is just impractical.
UV light disinfection is already being used in a number of industries and applications, such as:
UV eliminates bacteria -- even the antibiotic-resistant ones. This is especially helpful for high-risk patients who might have been infected with resistant bacteria. And while traditional cleaning methods like chemicals might kill only around 80% of pathogens, when combined with an indoor air filtration system, UV can kill all airborne pathogens within seconds.
