58. Rinse And Dispose Of Chemical Containers Safely
|
 |
Empty pesticide containers are not really empty, for as much as
2 to 4 ounces of the chemical may remain inside an unrinsed container.
Therefore, rinse containers immediately after emptying them. The
two most common systems are the triple-rinse procedure and the jet-spray
system.
To triple-rinse a container, empty the container into the spray
tank and let it drain for 30 seconds. If the container is designed
to hold less than 5 gallons of pesticide, fill it one-fourth full
with clean water. If the container is designed to hold 5 gallons
of pesticide or more, fill it one-fifth with clean water.

Shake
or swirl the container vigorously to rinse all inside surfaces. Empty
rinsate into the spray tank and let it drain for 30 seconds. Then
repeat the procedure two more times and puncture the bottom so the
container cannot be reused. |
 |
Speed
is the advantage of jet spraying, or "pressure rinsing"—a
system in which you puncture the bottom of the container with the
pressure rinse nozzle, then rinse for sixty seconds. The rinsate will
drain directly into your spray tank. |
 |
Do
not dump pesticide container rinse water on the ground. Empty all
rinsate into your spray tank and apply it to your fields, as long
as you do not exceed label rates. If you cannot apply the rinse water
without exceeding rates, store it in a rinsate drum for later use
as mix water in the spray tank mix. |

Keep
in mind that there are ways to avoid the disposal dilemma entirely.
You can use disposable packages, designed to dissolve in the tank.
In some areas, you can recycle containers. You can also reuse mini-bulk
containers, and some manufacturers will allow you to return empty
containers. |
