As listed by the NIH Division of Occupational Health and Safety (DOHS), hospital disinfectants suitable for decontaminating the surfaces of scientific equipment include the following generic formulations: iodophors; chlorine solutions; alcohol (isopropyl, ethyl); phenolic compounds and quaternary ammonium compounds. Wescodyne (an iodophor) and sodium hypochlorite (bleach) are available in the NIH self-service stores.
For any disinfection procedure:
- Choose a disinfectant that is not corrosive or otherwise destructive to the items undergoing decontamination.
- Read and follow the manufacturer's label directions concerning the recommended disinfectant concentration, contact time, and method of application.
- Wear the appropriate gloves, lab coat, and eye protection whenever using chemical disinfectants.
- Determine if the design of the equipment or its construction materials will have an effect on the decontamination process. Crevices, joints, and pores constitute barriers to the penetration of liquid disinfectants. Prolonged contact time may be required to accomplish decontamination, depending on the intricacy of the design and the amount of soil present.
