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 (Hommel (1996)) |
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 (UN1066), Subsidiary risk is not 5.1, 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 is -147.0 degC (Weiss (2nd, 1986)) below -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) |

Hazard class | Classification | Symbol | Signal word | Hazard statement | Precautionary statement | Rationale for the classification | |
---|---|---|---|---|---|---|---|
1 | Acute toxicity (Oral) | Classification not possible | - | - | - | - | No data available. |
1 | Acute toxicity (Dermal) | Classification not possible | - | - | - | - | No data available. |
1 | Acute toxicity (Inhalation: Gases) | Not classified | - | - | - | - | It is reported that nitrogen gas is present in the atmosphere at high levels (80% or more) and toxicologically nitrogen acts only by the physiological effect of simple asphyxia (ACGIH (2001)), therefore, the level of oxygen is the critical factor in preventing asphyxia (ACGIH (2001), PATTY (5th, 2001)). The substance was classified as "Not classified" since there is no lethal effect by exposure at approximately 80% in the atmosphere. |
1 | Acute toxicity (Inhalation: Vapours) | Not applicable | - | - | - | - | Gas (GHS definition) |
1 | Acute toxicity (Inhalation: Dusts and mists) | Not applicable | - | - | - | - | Gas (GHS definition) |
2 | Skin corrosion/irritation | Classification not possible | - | - | - | - | No data available. |
3 | Serious eye damage/eye irritation | Classification not possible | - | - | - | - | No data 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. |
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, nitrogen gas is present in the atmosphere at high level (80% and above), and toxicologically acts by only physiological effect of simple asphyxias (ACGIH (2001)). |
9 | Specific target organ toxicity - Repeated exposure | Classification not possible | - | - | - | - | No data available. |
10 | Aspiration hazard | Not applicable | - | - | - | - | Gas (GHS definition) |

11 | Hazardous to the aquatic environment (Acute) | Classification not possible | - | - | - | - | No data available. |
11 | Hazardous to the aquatic environment (Long-term) | Classification not possible | - | - | - | - | No data available. |
