| 5 | Gases under pressure | Liquefied gas |
|
Warning | H280: Contains gas under pressure; may explode if heated | P410+P403: Protect from sunlight. Store in a well-ventilated place. | The boiling point is -41degC (ICSC 2004), and the critical temperature is 137degC (Merck (13th, 2001)) - i.e., liquefied gas. Classified into Divisions 2.1and 2.3 (UN#2202) (UN Recommendations on the Transport of Dangerous Goods) |

| 9 | Pyrophoric liquids | Not applicable | - | - | - | - | Classified as "gas" according to GHS definition |
| 10 | Pyrophoric solids | Not applicable | - | - | - | - | Classified as "gas" according to GHS definition |
| 11 | Self-heating substances and mixtures | Not applicable | - | - | - | - | Classified as "gas" according to GHS definition |
| 12 | Substances and mixtures which, in contact with water, emit flammable gases | Not applicable | - | - | - | - | Classified as "gas" according to GHS definition |
| 13 | Oxidizing liquids | Not applicable | - | - | - | - | Classified as "gas" according to GHS definition |
| 14 | Oxidizing solids | Not applicable | - | - | - | - | Classified as "gas" according to GHS definition |
| 15 | Organic peroxides | Not applicable | - | - | - | - | Classified as "gas" according to GHS definition |
| 16 | Corrosive to metals | Classification not possible | - | - | - | - | Test methods applicable to gaseous substances are not available |
| 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） | Classification not possible | - | - | - | - | No data available |
| 1 | Acute toxicity （Inhalation: Vapours） | Not applicable | - | - | - | - | Due to the fact that the substance is "gas" according to the GHS definition and inhalation of its vapour is not expected. |
| 1 | Acute toxicity （Inhalation: Dusts and mists） | Not applicable | - | - | - | - | Due to the fact that the substance is "gas" according to the GHS definition and inhalation of its dust/mist is not expected. |
| 2 | Skin corrosion/irritation | Classification not possible | - | - | - | - | Insufficient data available |
| 3 | Serious eye damage/eye irritation | Category 2A-2B |
|
Warning | H319: Causes serious eye irritation |
P305+P351+P338: IF IN EYES: Rinse cautiously with water for several minutes. Remove contact lenses, if present and easy to do. Continue rinsing. P337+P313: If eye irritation persists: Get medical advice/attention. P264: Wash ... thoroughly after handling. P280: Wear protective gloves/protective clothing/eye protection/face protection. |
Based on a report of accidental exposure of a worker handling selenium hydride (EHC 58 (1986)): "Accidental eye spillage of selenium hydride caused burning sensation and lacrimation." The substance should be placed in Category 2A from the viewpoint of safety, if further subclassification is needed. |
| 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 | Not classified | - | - | - | - | Due to the fact that the substance is classified as Category D by EPA (1993) and Group 3 by IARC (1987). |
| 7 | Reproductive toxicity | Classification not possible | - | - | - | - | No data available |
| 8 | Specific target organ toxicity - Single exposure | Category 1 (respiratory system, heart, blood system, liver) |
|
Danger | H370: Causes damage to organs (respiratory system, heart, blood system, liver) |
P307+P311: IF exposed: Call a POISON CENTER or doctor/physician. P260: Do not breathe dust/fume/gas/mist/vapours/spray. P264: Wash ... thoroughly after handling. P270: Do not eat, drink or smoke when using this product. P321: Specific treatment （see ... on this label）. P405: Store locked up. P501: Dispose of contents/container to ... |
Based on the human evidence including "changes in pulmonary function persisted for 3 years" (PATTY (4th, 2000)), "pulmonary edema, changes in myocardium found in ECG records and porphyrinuria" (EHC 58 (1986)), and the evidence from animal studies including "liver damage" (ACGIH (7th, 2001)). The effects on experimental animals were observed at dosing levels within the guidance value ranges for Category 1 (liver). |
