Hand Washing and Public Health Hand washing can considerably contribute to an improved and sustainable sanitation system by interrupting the transmission of disease agents. Consequently, diarrhoea, respiratory infections as well as skin infections and trachoma are significantly reduced. Example: A study suggests that hand washing with soap, particularly after contact with faeces (post-defecation and after handling a child’s stool), can reduce diarrhoeal incidence by percent.

Simple Hand Washing Devices Find this presentation and more on: Design Concerns Technical considerations: Convenient location of facilities (i.e. close to work place, community centre, toilet facilities, etc.) Convenient installation (e.g. height suit both children and adults) Clean area / comfort (e.g. drainage, frequent cleaning) Properly working devices (e.g. frequent maintenance) 9 3. Design of Hand Washing Devices BUT: That’s not good enough! Need for making users understand of the purpose and benefits of hand washing (awareness raising) in order to make the consequent use of hand-washing facilities an integral part of people’s daily routines.

After filled with water, hands can be washed while the water is slowly trickling down. This low-cost option is applied easily and very effectively Design of Hand Washing Devices Source: MORGAN (2009)Source: SUSANA (2006)
