SECH ultracapacitors

ADG classification

of Danger According to Regulation (EC) No. 1272/2008 (CLP) This ultracapacitor is a manufactured electronic product that contains primarily non-hazardous materials, including metal and plastic. Ultracapacitors are sealed, aluminium containers, which enclose layers of activated carbon that is saturated with an electrolyte solution. The electrolyte solution can contain a quaternary salt compound (tetraethylammonium tetrafluoroborate, TEABF4) dissolved in the solvent acetonitrile. The assembled layers of activated carbon are inserted into an outer metal container and are saturated with the above electrolyte solution and then are sealed and stored in an electrically uncharged state. If the contents of these ultracapacitors remain sealed in the outer shell and they are kept uncharged, persons handling these products will avoid most of the risks associated with hazardous components of the electrolyte. As such, precautions should be taken to avoid rupture or overheating the sealed metal containers. Capacitors containing electrolyte are considered to be articles under REACH-regulation. Therefore, substance registration requirements do not apply to the substances contained in capacitors. CLP- regulation compliant classification and REACH- regulation compliant SDS are to be provided for substances and mixtures only. The current product is an article, therefore classification, labelling and SDS are not a legal requirement.  According EC regulation 1272/2008 (CLP): Not applicable. The product is not a substance or a mixture, but an article. Providing the SDS takes place on a voluntary basis for information purposes only.  Labelling according to Regulation (EC) No. 1272/2008 [CLP] not applicable. There is no legal requirement for the product to be specially labelled.

Product definition

This product is a solid article consisting of plastic and metal sealed case, which is filled with an electrolyte solution that has been almost completely adsorbed and or absorbed by the activated carbon layers.

Health hazards

This product is considered a manufactured article and presents negligible health hazards under typical use conditions. Misuse of this product, such as deliberate destruction, overcharging or heating, may release internal components contained within the sealed case. Skin contact with the carbon may cause mild irritation. FLAMMABILITY HAZARDS: The internal components of this product are combustible and may be ignited if a particular failure mode occurs and they are exposed to an ignition source or if subjected to direct flame. If the article is involved in a fire, the chemicals contained in the case may decompose and produce toxic gases (e.g. nitrogen oxides, carbon oxides, hydrogen cyanide, hydrogen fluoride and other miscellaneous fluoride and boron compounds). During a fire involving this product, care should be taken to avoid inhalation of fumes. Misuse of this product, such as overcharging, may cause the article to vent which could then cause the release of these toxic fumes as well. REACTIVITY HAZARDS: Negligible.

Environmental hazards

Negligible EMERGENCY CONSIDERATIONS: Emergency responders must wear the proper personal protective equipment (and have appropriate fire-suppression equipment) suitable for the situation to which they are responding. Appropriate precautions should be taken in the event of a container rupture under emergency conditions including fire.
