High-level disinfection definition

High-level disinfection means a disinfection method that results in a fecal coliform concentration less than or equal to 2.2 colonies/100 ml. Chlorine disinfection requires a minimum total residual chlorine (TRC) concentration at the end of a 30 minute contact time of 1.5 mg/l. Ultraviolet disinfection requires a minimum dose of 50,000 μW-sec/cm2. Influent turbidity to the disinfection unit shall be less than or equal to 2 Nephelometric turbidity units (NTU) on average.

More Definitions of High-level disinfection

High-level disinfection means the disinfection process that inactivates some, but not necessarily all, bacterial spores. This powerful process will also kill M. tuberculosis var. bovis, (a resistant laboratory test organism used to classify the potencies of disinfectant chemicals), as well as other bacteria, fungi, and viruses. High-level disinfection is the minimum treatment recommended by the CDC in guidelines for the reprocessing of semi-critical instruments or devices. Examples of high-level disinfectants includes glutaraldehyde-, chlorine dioxide-, hydrogen-peroxide, orthophthaldehyde-, and peracetic acid-based formulations. These are commercially available germicides that have been cleared by the FDA as sterilants/disinfectants (all but one product to date) or simply as "high level disinfectants." Items must be properly cleaned before disinfection is performed with these solutions.

High-level disinfection means a type of disinfection which destroys all microorganisms with the exception of high levels of bacterial spores. Such disinfection may be accomplished through the use of processes that include, without limitation, boiling items in water, steaming items in water and soaking items in chemical disinfectants.
