Introduction
Hand hygiene is crucial for preventing the spread of infectious diseases. Traditional hand washing methods require water and soap, which may not be readily available in certain environments. A dry hand wash machine using fog disinfection offers a convenient and effective alternative. This machine will use a fine mist of disinfectant to sanitize hands, providing a quick and efficient solution for maintaining hand hygiene in various settings, including healthcare facilities, public places, and remote locations.
Problem Statement
In many regions, access to clean water is limited, making traditional hand washing challenging. Additionally, conventional hand sanitizers can be messy and may not evenly cover all surfaces of the hands. There is a need for an innovative hand hygiene solution that does not rely on water and ensures thorough disinfection. The development of a dry hand wash machine using fog disinfection technology addresses this need by offering a waterless, efficient, and effective method for sanitizing hands.
