Rinsing Chemical Containers

Triple Rinsing - Guidelines and best practice

Triple Rinsing of chemical containers may not necessarily render them non hazardous or suitable for recycling. The effectiveness of the rinsing depends on whether or not the chemical has infiltrated the fabric of the container, and this depends on the type of chemical, how long the container has been stored and under what conditions. Your supplier/manufacturer should be able to advise you on whether the chemical is likely to have infiltrated the fabric of the container. You should contact your supplier/manufacturer in advance to establish this information before embarking on any triple rinsing procedure.

  1. Empty the pesticide into the sprayer tank and let the container drain for 30 seconds.
  2. Fill the container 10 percent to 20 percent full of water or rinse solution.
  3. Put the cover on the container.
  4. Swirl the container to rinse all inside surfaces.
  5. Add the rinsate to the spray tank and let drain for 30 seconds.
  6. Repeat steps 2 through 5 two more times.
  7. Inspect the container to be sure it is clean. Chemical may remain in the corners, the handle and container threads. This must be removed. Also, be sure drips on the outside of containers are cleaned off.
  8. Put the cover back on the container and dispose of according to label directions. If containers are to be recycled, leave the cover off and store in a dry, secure area.
  9. It is the responsibility of every farmer to ensure that they do not present contaminated containers for recycling.
