Touch Points

“Touch-Point” analysis is a method used in evaluating how often objects in an environment are handled, how often they are touched, and by how many people. The human hand carries all the nutrients and conditions to promote the growth of germs and microbes. When these hands touch a surface they “applyā€¯ these to the touched surface.

Touch-Points must be prioritized in order to develop a program of treatment. The most important points of treatment will always be those surfaces which are touched several times a day by several people.

There are five parts to consider when completing the inspection form.

1- Is the information regarding the client and also the applicator.

2- Priority, which should be numbered from 1 to 4.

3- Description of the location and touch-point (i.e. cash register keyboard, or telephone).

4- Square foot of area. This would represent a estimation or guess of the total square feet of the surface area (on any small points it is recommended you use a minimum of one square foot).

5-The last item is the RLU which stands for relative light units. This would be the number registered after a swab and Luminometer test.


Try to list at least 10 or more priority 1 & priority 2 items
