Guidelines for Disinfectants

Disinfection prevents disease transmission through inanimate objects. Especially important in medical environments, disinfection could inactivate blood-borne pathogens such as human immunodeficiency virus (HIV). Because the object to be cleaned could contain dangerous materials and the disinfectant could cause irritation, you should follow some guidelines when using disinfectants.

Pre-Cleaning

• Proper disinfection requires cleaning because some substances such as dirt, blood and mucus on the object to be disinfected could bind up the active ingredients of the disinfectant and reduce their effectiveness. Use general surface cleaner to remove dirt, debris and various microorganisms.

Equipment

• If the object only touches intact skin, it might only need general surface cleaning. If you want to target specific microbes such as bacilli, spores or viruses, choose the appropriate disinfectant. It should work effectively on your target and present the smallest danger to people and the environment. It should also not damage the surface you want to clean. Avoid direct contact with chemical disinfectants by wearing protective equipment such as goggles and gloves when cleaning and decontaminating items. Use washable towels and applicators to reduce waste.

Disinfectant Handling

• A disinfectant should have direct contact with the surface, so remove any trapped air before applying disinfectant. A disinfectant has to have sufficient concentrations and remain within a correct temperature range. It also has to stay in contact with the surface to be cleaned for a certain period of time to penetrate the object thoroughly. The concentration, temperature and exposure time depends on the particular type and brand of disinfectant, so follow the manufacturer's instructions closely. Rinse the disinfectant from the object thoroughly after the specified amount of time. Don't mix disinfectants with other chemicals because doing so could inactivate the disinfecting ingredients or produce noxious fumes.

Spills

• Disinfectants could be toxic and corrosive, so avoid spills and clean any spills immediately. Store them in disinfectant containers, preferably ones with pumps and spigots. Pouring disinfectants increases the probability of spills and skin contact. Place pans under any spouts to catch drips. Only transfer disinfectants from container to container when necessary.
