Category 1 because "the flammable range with air is 95.2-97.2%" (Hazardous Materials DB, 2nd, 1993) and the lower flammable limit is 0.8-2.8 vol%. (It is ignitable when in a mixture of 13% or less by volume in air.) |

| 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） | Category 1 |
|
Danger | H330: Fatal if inhaled |
P304+P340: IF INHALED: Remove victim to fresh air and keep at rest in a position comfortable for breathing. P403+P233: Store in a well-ventilated place. Keep container tightly closed. P260: Do not breathe dust/fume/gas/mist/vapours/spray. P271: Use only outdoors or in a well-ventilated area. P284: Wear respiratory protection. P310: Immediately call a POISON CENTER or doctor/physician. P320: Specific treatment is urgent （see ... on this label）. P405: Store locked up. P501: Dispose of contents/container to ... |
It was considered as Category 1 based on guinea pigs LC50 value = 260mg/m3 (equivalent: 83ppm) (RTECS (2004)) in the 4-hour inhalation experiments. |
| 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 | Category 2 |
|
Warning | H315: Causes skin irritation |
P302+P352: IF ON SKIN: Wash with plenty of soap and water. P332+P313: If skin irritation occurs: Get medical advice/attention. P264: Wash ... thoroughly after handling. P280: Wear protective gloves/protective clothing/eye protection/face protection. P321: Specific treatment （see ... on this label）. P362: Take off contaminated clothing and wash before reuse. |
Since there was a description of redness and pains as danger information on human health (ICSC (J), (1995)), it was classified as Category 2. |
| 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. |
Since there is a statement that the eye had redness and paint (ICSC (J), (1995)) as danger information on human health , it was set as Category 2A-2B. |

P309+P311: IF exposed or if you feel unwell: Call a POISON CENTER or doctor/physician. P304+P340: IF INHALED: Remove victim to fresh air and keep at rest in a position comfortable for breathing. P403+P233: Store in a well-ventilated place. Keep container tightly closed. P261: Avoid breathing dust/fume/gas/mist/vapours/spray. P271: Use only outdoors or in a well-ventilated area.

The denaturation of liver and kidney tissue and the effects on central nervous system are observed in the dosage range of the guidance value of Category 1 in animal studies (ACGIH (2001), RTECS (2004)). There is the description that an it irritates to airway as effect of short-term exposure to human and affectes to blood (ICSC (J) (1995)). Moreover, there are the descriptions that in human, it may cause the symptoms, such as headache, giddiness, syncope, and vomiting, and it causes the kidney disorders by the cythemolytic gas, and there is the description that the targets of toxic effects are central nervous systems, kidney and blood (SITTIG (4th, 2002)). From these results, they were classified into Category 1 (liver, kidney), Cateogry 2 (blood), and Category 3 (anesthetic actions, respiratory irritant). |
| 9 | Specific target organ toxicity - Repeated exposure | Classification not possible | - | - | - | - | It cannot be classified because of lack of information. In addition, there is the statement in SITTIG (4th, 2002) that prolonged exposure may cause kidney disorders and a haemolytic activity in humans. |
| 10 | Aspiration hazard | Not applicable | - | - | - | - | Gas (GHS definition) |
| Hazard class | Classification | Symbol | Signal word | Hazard statement | Precautionary statement | Rationale for the classification | |
|---|---|---|---|---|---|---|---|
| 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. |
