|Significance and Use|
5.1 Hand hygiene is considered one of the most important measures for preventing the spread of infectious microorganisms. Hand rubs reduce the microbial load on the hands without the use of soap and water, and are thus an important tool in the practice of good hand hygiene. Alcohol-based hand rubs are recommended in healthcare settings for use on hands that are not visibly soiled. They are formulated to be applied full strength to dry hands, “rubbed in” until dry, and are not rinsed off.
5.2 This test method is designed specifically to evaluate hand rubs for efficacy in eliminating bacteria from experimentally-contaminated hands. It is designed as an alternative to Test Method , which was intended primarily to evaluate antimicrobial handwashing agents that are lathered with the aid of water and then rinsed off. When using Test Method to evaluate hand rubs, inadequate drying of the hands after contamination dilutes the test material and can compromise activity, to result in an underestimation of effectiveness. Additionally, because hand rubs are not rinsed after product use, activity can be further degraded by build-up of soil from the contaminating broth and inactivated challenge bacteria on the hands.
5.2.1 In this method, application to the hands of a small volume of high-titer test bacteria suspension minimizes soil load such that the skin is completely dry prior to application of the test material. Further, by applying the bacterial suspension only prior to those test material application cycles followed by sampling, excessive buildup of killed bacteria on the hands is avoided, and the potential impact of non-volatile test product ingredients on bacteria-eliminating effectiveness after ten consecutive applications can be specifically assessed.
5.3 A reference control is evaluated for each subject prior to evaluation of the test material. Data from the reference control helps to control for inter-subject variability, inter-experimental variability, and inter-laboratory variability; and enables improved statistical comparison of test materials evaluated in the same experiment.
5.4 This test method can be used to test any form of hand rubs, including gels, rinses, sprays, foams, and wipes when used according to label directions at typical “in-use” doses.
5.5 Susceptibility to biocides can vary among different species of bacteria and major differences have been noted between gram-negative and gram-positive organisms. This test method provides the option to use either a gram-negative bacterium (5.6 This test method may be used as an alternative to Test Method , which limits the test bacteria to the fingerpads and does not incorporate actual use conditions such as friction during hand rubbing.
5.7 The investigator should be aware of potential health risks associated with the use of these organisms and precautions similar to those referenced in Section should be taken.
1.1 This test method is designed to determine the activity of healthcare personnel hand rubs, (also known as hand rubs, hygienic hand rubs, hand sanitizers, or hand antiseptics) against transient microbial skin flora on the hands after a single application and after repeated applications.
1.2 Performance of this procedure requires the knowledge of regulations pertaining to the protection of human subjects (see 21 CFR Parts 50 and 56).
1.3 This test method should be performed by persons with training in microbiology, in facilities designed and equipped for work with potentially infectious agents at biosafety level 2.1.4 Units—The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
