Detailed explanation-1: -The infrared sensors of the automatic hand sanitizer dispenser detect the infrared energy that is emitted by one’s body heat. When hands are placed in the proximity of the sensor, the infrared energy quickly fluctuates. This fluctuation triggers the pump to activate and dispense the designated amount of sanitizer.
Detailed explanation-2: -In a hospital setting, UV-C can be employed to disinfect the air of bacterial particles with the use of the upper room UV-C lights. This strategy may be useful for reducing HAIs.
Detailed explanation-3: -UV disinfection lamps are also used in the heating and cooling systems of hospitals to purify and disinfect the air in hospitals where people are more vulnerable to illness.
Detailed explanation-4: -UV light is helping hospitals to reduce transmission of the toughest superbugs that linger in patient rooms and cause new infections. UV light in the UVC wavelength, specifically at 254 nm, is proven to eliminate even the toughest of superbugs and is helping hospitals to reduce the spread of infection.
