Put a handwashing station with soap or wood ash and flowing clean water at the kitchen entrance, at the dining-room door and at every latrine, and make washing there a condition of entering the kitchen. People must scrub all surfaces of their hands for at least 20 seconds, because most people wash for only 6-9 seconds, which is not enough to clear pathogens.
A handwashing station is a fixed point with water, soap or ash, a catch basin and a dry cloth where people clean their hands before handling or eating food.
The Station Has To Be Easier To Use Than To Skip
The parent guide makes handwashing mandatory at a station by the kitchen entrance, with soap and water and no exceptions. The corpus guide on Hand Washing gives the technique: lather with soap (or ash), scrub palms, backs, between fingers, under nails and wrists for at least 20 seconds, rinse under flowing water, and dry on a cloth used only for that purpose. It adds that most people wash for 6-9 seconds. The corpus campaign guide (Hand Washing) reports that handwashing at the right moments cuts childhood diarrhoea by 30-50 percent, and advises building handwashing stations before the kitchen or meeting hall itself.
A station that nobody uses is not a control. Placement, water flow and habit decide whether it works.
What You Need
- A water supply that flows, not a bowl: a jug or barrel with a tap, or a hanging container that tips from a foot lever (a tippy-tap), so that hands are never dipped into used water
- Soap, or wood ash, kept dry and within reach (Soap Making for the soap)
- A catch basin and drain leading to the grease trap or soak pit (Greywater Management)
- A clean cloth for hands only, or air drying
- Fresh water, refilled every shift from a clean source (Storage Hygiene explains why a shared dipper undoes purification)
Method: Place And Run The Stations
Step 1: Site three stations at minimum: kitchen entrance, dining entrance, and each latrine. The parent requires the first; the campaign guide asks for one at every latrine and food-preparation area.
Step 2: Set the water flow so that one person can wash with both hands free. A barrel with a tap on a stand, or a tipped container, works; a bowl does not.
Step 3: Count the moments that need a wash: before handling food, after the latrine, after handling raw meat and after touching the face (Food Safety Standards).
Step 4: Time the wash. Teach a count or a verse that lasts at least 20 seconds, and put a mark beside the station.
Step 5: Plan the water. Measure how much your own spout uses, then multiply. As an illustration only: if one wash used 0.5 litre (an assumed figure, not a measurement), 100 people washing before a meal would use 50 litres, and a kitchen team of 4-6 washing four times in a shift would add 8-12 litres. Time a real wash and use that number.
Common Mistakes
- A shared bowl. The water becomes a pathogen soup after the third user.
- Station out of sight or out of the way. If the walk to the station is longer than the walk to the door, people skip it.
- No soap restocking. An empty soap dish ends the habit within days.
- Explaining nothing. The corpus hygiene-education guide notes that a settlement that builds the station without explaining why still sees diarrhoeal illness (Hygiene Education).
Safety
Wood ash and lye can burn skin
Dry ash or an ash-and-water paste is a gentle abrasive, but strong ash lye is caustic and burns skin and eyes. Use ash dry or as a thin paste, never a concentrated lye solution, rinse hands thoroughly, and keep any lye in the kitchen for cleaning labelled and out of the handwashing area (Lye from Ash).
