Substance information(collapsed)

The BAM name is based on the "name and description" from the regulations and the IUPAC rules, but may be supplemented with further information so that significant differences between two dangerous goods data sets are apparent.

Language BAM name
German Cyanwasserstoff, nicht stabilisiert
English Hydrogen cyanide, unstabilized
French Cyanure d'hydrogène, non stabilisé

The aggregate state is given under normal conditions, i.e. at room temperature of 20 °C and normal pressure of 101.3 kPa.

Aggre­gate state
under normal con­di­tions liquid
during trans­port unstated

The formula describes the chemical composition of a substance.

Formula
HCN

The BAM number is used to uniquely identify a substance or object in the BAM dangerous goods data pool.

Limited and excepted quantities(collapsed)

Values in "ml" and "L" refer to substances that are liquid under normal conditions (temperature 20 °C, density 1013 mbar). Values in "g" and "kg" refer to substances that generally have a melting point greater than 20 °C. Solid substances that can liquefy during transport may only be transported in packagings that are suitable for liquids (paper bags, for example, are not permitted).

Exceptions(collapsed)

The following is a list of exceptions from the regulations on the transport of dangerous goods (Gefahrgut-Ausnahmeverordnung - GGAV 2002, PDF (German)), which may be relevant for the current substance for transport within Germany.
The scope of the GGAV refers to the GGVSEB (Gefahrgutverordnung Straße, Eisenbahn und Binnenschifffahrt) and GGVSee (Gefahrgutverordnung See).

Exception Title Validity
not stated - carriage is forbidden

The Memorandum of Understanding for the transport of packaged dangerous goods by Ro/Ro ships in the Baltic Sea is a further exception in accordance with section 7 paragraph 2 of the GGVSee in conjunction with section 7.9.1 of the IMDG Code.

Chapter 1.4 Security provisions

Mixed packing(collapsed)

The mixed packing of two or more dangerous goods is only permitted if the goods are compatible with each other. According to 7.2.2.1, two substances or articles are considered incompatible if, as a result of their being packed or stowed together, unacceptable hazards may arise in the event of leakage or escape of the contents or in the event of any other accident.

Note:
For guidance, refer to the general stowage and segregation instructions and to the segregation table in the section on mixed loading/stowage/segregation.

Note on mixed packing of limited quantities (3.4.4.1):
Different dangerous goods in limited quantities may be packed together in an outer packaging provided that the segregation provisions of Chapter 7.2 are taken into account and the goods do not react dangerously with each other in the event of leakage.
