Product
The material can be disposed of by removal to
a licensed
chemical destruction plant or by controlled incineration
with flue gas scrubbing. Do not
contaminate water, foodstuffs,
feed or seed by storage or disposal. Do not discharge to sewer
systems.
Contaminated packaging
Containers can be triply rinsed (or equivalent) and
offered
for recycling or reconditioning.
Alternatively, the packaging can be punctured to
make it
unusable for other purposes and then be disposed of
in a sanitary landfill. Controlled
incineration
