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
with flue gas scrubbing is possible for combustible packaging materials.

Other Information

The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort.Rest and medical observation is therefore essential.Immediate administration of an appropriate inhalation therapy by a doctor or a person authorized by him/her, should be considered.

FluorineFluorine is a chemical element with the symbol F and atomic number 9.
It is the lightest halogen and exists as a highly toxic pale yellow diatomic gas at standard conditions. As the most electronegative element, it is extremely reactive, as it reacts with almost all other elements, except for helium and neon.
Fluorocarbon gases are generally greenhouse gases with global-warming potentials 100 to 20,000 times that of carbon dioxide.
Organofluorine compounds often persist in the environment due to the strength of the carbon–fluorine bond. Fluorine has no known metabolic role in mammals; a few plants and sea sponges synthesize organofluorine poisons (most often monofluoroacetates) that help deter predation.

SiliconSilicon is a chemical element with the symbol Si and atomic number 14.
It is a hard and brittle crystalline solid with a blue-grey metallic lustre; and it is a tetravalent metalloid and semiconductor.
It is a member of group 14 in the periodic table: carbon is above it; and germanium, tin, and lead are below it.
