Guidelines
1 . Read the whole chemical label. Take note of any particular instructions regarding recommended protective clothing,
deactivating agents, etc. Read the detergent and deactivating agent labels. If cleaning procedures are given, follow
them closely.
2. Be familiar with local legislation regarding disposal of pesticides washings, mandatory decontamination methods, etc.
Contact the appropriate department, e.g. Dept. of Agriculture.
3. Pesticide washings can usually be sprayed out on a soakaway. This is an area of ground that is not used for cropping.
You must avoid seepage or runoff of residue into streams, water courses, ditches, wells, springs, etc. The washings from
the cleaning area must not enter sewers. Drainage must lead to an approved soakaway.
4 . Cleaning starts with the calibration, as a well calibrated sprayer will ensure the minimal amount of remaining spray
liquid.
5 . It is good practice to clean the sprayer immediately after use and thereby render the sprayer safe and ready for the next
pesticide application. This also prolongs the life of the components.
6. It is sometimes necessary to leave spray liquid in the tank for short periods, e.g. overnight, or until the weather becomes
suitable for spraying again. Unauthorized persons and animals must not have access to the sprayer under these
circumstances.
7. If the product applied is corrosive, it is recommended to coat all metal parts of the sprayer before and after use with a
suitable rust inhibitor.
