Recently our factory is looking into the option of installing UV light at the production area. The idea is to turn on the UV light at night (non production hour) to kill microbes at the surface of equipments/machinery and air borne microbes. The ultimate goal is to improve the production environment and food safety. Wondering does it make sense? If yes, can anyone advise on the specification of the UV lamp and every how many square feet of area should have one UV light?
