CH-UH Partners with âRight At Schoolâ to Expand Before & After School Care. April 10, 2017 -- The CH-UH City School District has partnered with Right At School to expand the before and after school care opportunities in each of its elementary schools beginning in the fall of 2017.
Many studies have been conducted to evaluate hand washing techniques.[1,4] The following general observations were noted: â¢ The use of 3 to 5 ml antiseptic soap was sufficient; more than 1 ml non-antiseptic soap did not enhance cleaning. â¢ A washing duration of 5 to 30 seconds can be effective.
Interestingly if you look at the official guidelines for hand washing from the CDC and WHO, both do not actually specify a water temperature. They do recommend using soap and water and scrubbing using proper technique for at least 20-seconds, followed by drying hands thoroughly.
