Acetylene

EC / List no.: 200-816-9

CAS no.: 74-86-2

Mol. formula: C2H2

formula
GHS02: Flammable GHS04: Gas under Pressure

Danger! According to the harmonised classification and labelling (CLP00) approved by the European Union, this substance is an extremely flammable gas.

Additionally, the classification provided by companies to ECHA in REACH registrations identifies that this substance is an extremely flammable gas and may react explosively even in the absence of air.

This substance is manufactured and/or imported in the European Economic Area in 100 000 - 1 000 000 tonnes per year.

This substance is used by consumers, in articles, by professional workers (widespread uses), in formulation or re-packing, at industrial sites and in manufacturing.

This substance is used by consumers, in articles, by professional workers (widespread uses), in formulation or re-packing, at industrial sites and in manufacturing.

Consumer Uses

This substance is used in the following products: fuels.
Other release to the environment of this substance is likely to occur from: indoor use in close systems with minimal release (e.g. cooling liquids in refrigerators, oil-based electric heaters) and outdoor use in close systems with minimal release (e.g. hydraulic liquids in automotive suspension, lubricants in motor oil and break fluids).

Article service life

Release to the environment of this substance can occur from industrial use: manufacturing of the substance, in processing aids at industrial sites and as an intermediate step in further manufacturing of another substance (use of intermediates).
