Make it step by step
- Step 01
Set the base level and low. Test with an empty container. Water weighs about 1 kg per litre; use a manufactured stand if capacity is uncertain.
- Step 02
Support the entire container bottom with the tap slightly over the edge. Strap against sliding and place the tray beneath.
- Step 03
Fill gradually and recheck. Keep soap out of wastewater and never reuse the catch tray's water for washing hands.
- Step 04
Wet hands, lather with soap for at least 20 seconds, rinse and dry. Dispose of collected water at the site's designated point.
Check before use
The container stays put while operating the tap, the tray does not overflow and soap is available.
Limits of this project
Do not put large containers on tall experimental stands. Keep soap out of streams, including biodegradable soap.
Take down and restore
Dispose of wastewater as permitted, clean the container and pack the base.
All lashings and racks here are for light objects, never people, climbing or rescue.
