PHYSICAL HAZARDS
Hazard class Classification Symbol Signal word Hazard statement Precautionary statement Rationale for the classification
1 Explosives Not applicable - - - - Gas (GHS definition)
2 Flammable gases (including chemically unstable gases) Not classified - - - - Not combustible gas (Merck (14th, 2006))
3 Aerosols Not applicable - - - - Not aerosol products.
4 Oxidizing gases Not classified - - - - Classified into Not classified since the substance is classified into Division 2.2 in UNRTDG (UN1046) but Subsidiary risk is not 5.1, and further ERG is 121 (Gases - Inert).
5 Gases under pressure Compressed gas Warning H280: Contains gas under pressure; may explode if heated P410+P403: Protect from sunlight. Store in a well-ventilated place. Critical temperature 5.2014 K (-267.9 degC) (Merck (14th, 2006)) is below -50 degC and boiling point at standard atmosphere is -268.926 degC (Merck (14th, 2006)), therefore the substance gasifies completely at -50 degC.
6 Flammable liquids Not applicable - - - - Gas (GHS definition)
7 Flammable solids Not applicable - - - - Gas (GHS definition)
8 Self-reactive substances and mixtures Not applicable - - - - Gas (GHS definition)
9 Pyrophoric liquids Not applicable - - - - Gas (GHS definition)
10 Pyrophoric solids Not applicable - - - - Gas (GHS definition)
11 Self-heating substances and mixtures Not applicable - - - - Gas (GHS definition)
12 Substances and mixtures which, in contact with water, emit flammable gases Not applicable - - - - Gas (GHS definition)
13 Oxidizing liquids Not applicable - - - - Gas (GHS definition)
14 Oxidizing solids Not applicable - - - - Gas (GHS definition)
15 Organic peroxides Not applicable - - - - Gas (GHS definition)
16 Corrosive to metals Classification not possible - - - - Test methods applicable to gaseous substances are not available.

4 Respiratory sensitization Classification not possible - - - - No data available.
4 Skin sensitization Classification not possible - - - - No data available.
5 Germ cell mutagenicity Classification not possible - - - - No data available.
6 Carcinogenicity Classification not possible - - - - No data available. The substance is not on list of carcinogenic substances in IARC.
7 Reproductive toxicity Classification not possible - - - - No data available.
8 Specific target organ toxicity - Single exposure Classification not possible - - - - No data available. As relevant information, helium is a simple asphyxiant and does not cause any significant physiological effect when present at high levels in ambient air (ACGIH (2001)).
9 Specific target organ toxicity - Repeated exposure Classification not possible - - - - No data available.
10 Aspiration hazard Not applicable - - - - Gas (GHS definition)
