As illustrated by the Ishikawa diagram ( Fig. Many factors influence an effective safety and sanitation program, with the best approach generally being more complex than simply grabbing a bottle of bleach. Also, testing devices must be used to measure the concentration of chemical sanitizing solutions because: (1) the use of chemical sanitizers requires minimum concentrations of the sanitizer during the final rinse step to ensure sanitization and (2) too much sanitizer in the final rinse water could be toxic. Factors affecting the action of chemical sanitizers: 1. Likewise the use of appropriate test methodologies should enable manufacturers and the end users to be confident about the claimed microbicidal activity of a product. Contact time. Increase in temperature causes the disinfectant to degrade and weakens its germicidal activity and thus might produce a potential health hazard. A.
