- Take the container cap off and carefully pour the rinse water into
the spray tank.
- Keep holding the container over the spray tank opening
for approximately 30 seconds to the last drop.
- REPEAT this operation twice more. This way, you complete the
TRIPLEWASH.
- Next, make the plastic and metallic containers
useless by piercing with a pointed instrument the
containers bottom. This way, their labels are not
damaged for identification purposes.
- The useless containers can be stocked temporarily in an appropriate place, until final
destination.
- In the case of mid and large size container (50, 100 and 200 liters), after washing with the
appropriate volume (1/4 of the total) and fitting the cap, roll it on the ground during approximately
30 seconds.
- Then in the upright position complete the agitation by moving back and forth for approximately
30 seconds.
- Then, empty the container by pouring the rinse water into the spray tank.
- REPEAT this operation twice more. In the last one, empty totally the container by pouring rinse
the water in the spray tank.
- The least the quantity of rinse water that remains in the container, from one wash to the next,
the most perfect and complete will be the decontamination.
- For the performance of the TRIPLE WASH, do not use a water volume either much lower or
much higher than 1/4 of the container capacity.
-The TRIPLE WASH must be done IMMEDIATELY AFTER emptying the container, during the
preparation of the solution
SOURCE - ANDEF (NATIONAL ASSOCIATION OF VEGETAL DEFENSE)

Even the containers considered empty contain chemical residues.
Some publications show that somewhere around 0.3% of the chemicals remains in the
container after being used.
Therefore, discarding the containers without washing out the residues is extremely
dangerous to man, animals and environment.
In the case of metal, plastic and glass chemical containers, each container must be
rinsed three times to ensure the residues are completely removed.
This manual describeds how to make the TRIPLE WASH in a correct, safe and effective
way.
-During the TRIPLE WASH, you must use appropriate protective clothing, such as: gloves,
apron, boots, goggles and protective masks with appropriate filters.
- IMMEDIATELYAFTER emptying the container, you must keep it with
the opening upside down over the sprayer tank opening or over the
bucket that you are using to prepare the chemical mixture for at least
30 seconds, until no residue is left in the container, when the drops are
falling in long intervals.
- Next, hold the container in the upright position and fill it
with water up to 1/4. For example: in a 20-liter container,
put 5 liters of water.
- Fit the container cap and tight it enough to avoid leakage
during the agitation.
- Agitate the container strongly in all ways (horizontal and
vertical), during approximately 30 seconds to remove the
residues that are sticked to the container internal walls.
14-TROUBLESHOOTING
- Put about 2 liters of water in the tank.
- While operating the lever, look into the tank to see how the problem arises.
