Once the CPPs have been applied in the prescribed manner, certain steps must be taken to clean, maintain and store the used equipment and to ensure that no further contamination can take place. In this session, we will look at these post-application procedures.
Post-Application Procedures
The following procedures must be followed after completing the application, some of which are discussed in more detail in the remainder of this session:
- Clean all mixing and application equipment thoroughly and store in the prescribed manner.
- Clean all protective clothing and equipment thoroughly and store in the prescribed manner.
- Collect and dispose of empty containers and other waste products correctly, as discussed in section 6 of session 2, and ensure that no empty containers are reused.
- Apply personal hygiene and safety.
- Notify CPP manager of completion of work.
Cleaning Of Equipment
Once the spraying operation has been completed, all machinery must be washed with clean water and stored for future use.
If spraying equipment is not cleaned properly after use, the danger of contamination remains, and people, animals and the environment may be placed at risk. In addition, certain CPPs are corrosive and spraying equipment that is not properly washed may be damaged.
Spraying Equipment
- Spraying machines must be washed in an area with adequate, safe drainage such as a filling point with a good French drain and at least 50m away from any water sources.
- Once parked at the filling point, remove the filter, normally situated near the pump.
- Rinse the filter with clean water so that all residues are removed.
- Fill the spraying tank with water while the agitator (mixing mechanism) is running. Water will pour through the open filter rinsing the tank. The tank is considered clean only once all pesticide residues have been removed.
- Wash the outside of the spraying machine with a cloth to remove all spray residues.
- Only now the spraying machine can be parked in its designated area.
Other Equipment
All other equipment, such as brushes, knapsacks, mixing equipment, etc., must be washed with an appropriate liquid soap and well rinsed in a suitably well-drained area.
Personal Hygiene
On completing the spraying task, all persons involved should bathe and dress in CLEAN clothing. Do not put on the clothes that were used for the spraying operation unless they have been laundered properly.
After the application of a PPP has been completed, all the following steps must be followed:
- Clean all mixing and application equipment thoroughly and store in the prescribed manner.
- Clean all protective clothing and equipment thoroughly and store in the prescribed manner.
- Collect and dispose of empty containers and other waste products correctly, as discussed in section 6 of session 2, and ensure that no empty containers are reused.
- Apply personal hygiene and safety.
- Notify the crop protection manager that the work has been completed.
