Fumigation and fogging are two methods commonly used in pharmaceutical companies to control the microbial contamination in controlled area. But now a day’s fumigation of formaldehyde solution (HCHO) and potassium permanganate is banned by different regulatory agencies.
Fumigation is a method in which we use formaldehyde solution with potassium permanganate chemical in a predefined ratio. Formaldehyde is a strong disinfectant.
By adding potassium permanganate in formaldehyde a reaction take place and generate fumes. Generated fumes kill bacteria, fungus and their spores. This is very effective method to control the microbial contamination in cleanroom.
