Low-level disinfection means a type of disinfection which eliminates most bacteria, some viruses and some fungi, but which may not kill resistant microorganisms. Such disinfection may be accomplished through the use of processes that include, without limitation, soaking items in chemical disinfectants.
Sample 1
Low-level disinfection means that disinfection which kills most vegetative bacteria, fungi, and lipid viruses and does not kill spores and non-lipid viruses. Low-level disinfection is sometimes less active against some of the gram-negative rods (Pseudomonas) and Mycobacterium (TB).

More Definitions of Low-level disinfection

Low-level disinfection means a process capable of inactivating most bacteria, some viruses and fungi but not bacterial spores or Mycobacterium tuberculosis var. bovis. Examples of low-level disinfectants are quaternary ammonium compounds and certain iodophors or phenolics. Like intermediate-level products, low-level disinfectants are regulated by EPA and are appropriate for disinfecting environmental or medical equipment (non-instrument) surfaces.

  • low voltage means the set of nominal voltage levels that are used for the distribution of electricity and whose upper limit is generally accepted to be an a.c. voltage of 1000V ( or a d.c. voltage of 1500 V). [SANS 1019]

  • Maximum Concentration Level Assessment means the Maximum Concentration Level Assessment for the purposes of a Basic Comprehensive Certificate of Approval, described in the Basic Comprehensive User Guide, prepared by a Toxicologist using currently available toxicological information, that demonstrates that the concentration at any Point of Impingement for a Compound of Concern that does not have a Ministry Point of Impingement Limit is not likely to cause an adverse effect as defined by the EPA. The concentration at Point of Impingement for a Compound of Concern must be calculated in accordance with O. Reg. 419/05.
