Hazard class | Classification | Symbol | Signal word | Hazard statement | Precautionary statement | Rationale for the classification | |
---|---|---|---|---|---|---|---|
1 | Acute toxicity (Oral) | Not applicable | - | - | - | - | It cannot be administered orally because it is gas which does not dissolve into water easily. |
1 | Acute toxicity (Dermal) | Classification not possible | - | - | - | - | Since there is no experimental data, it cannot be classified. |
1 | Acute toxicity (Inhalation: Gases) | Category 3 | Danger | H331: Toxic 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. P261: Avoid breathing dust/fume/gas/mist/vapours/spray. P271: Use only outdoors or in a well-ventilated area. P311: Call a POISON CENTER or doctor/physician. P321: Specific treatment (see ... on this label). P405: Store locked up. P501: Dispose of contents/container to ... |
It was considered as Category 3 from data of rat LC50 (4hr): 1805ppm (IUCLID (2000)) and 1659ppm (RTECS (2004)). | |
1 | Acute toxicity (Inhalation: Vapours) | Not applicable | - | - | - | - | Gas (room temperature) |
1 | Acute toxicity (Inhalation: Dusts and mists) | Not applicable | - | - | - | - | Gas (room temperature) |
2 | Skin corrosion/irritation | Not classified | - | - | - | - | It is said to be tasteless odorless gas. (Merck 13th(2001)) |
3 | Serious eye damage/eye irritation | Not classified | - | - | - | - | It is called tasteless odorless gas. (Merck 13th.(2001)) |
4 | Respiratory sensitization | Not classified | - | - | - | - | Although smokers are inhaling daily, there is no sensitization data found. Since the same can be said of skin contacts, both items were put outside of the Category. |
4 | Skin sensitization | Not classified | - | - | - | - | Although smokers are inhaling daily, there is no sensitization data found. Since the same can be said of skin contacts, both items were put outside of the Category. |
5 | Germ cell mutagenicity | Not classified | - | - | - | - | We classified it as "Out Of Category" based on the evaluation review of WHO. |
6 | Carcinogenicity | Not classified | - | - | - | - | It carried out "Category Outside" from the evaluations review of WHO. |
7 | Reproductive toxicity | Category 1A | Danger | H360: May damage fertility or the unborn child |
P308+P313: IF exposed or concerned: Get medical advice/attention. P201: Obtain special instructions before use. P202: Do not handle until all safety precautions have been read and understood. P281: Use personal protective equipment as required. P405: Store locked up. P501: Dispose of contents/container to ... |
Since the effects on embryo is observed in many animal experiment and the effects on smoking of the mother was suggested also in humans, it is classified into the "Category 1A." | |
8 | Specific target organ toxicity - Single exposure | Category 1 (Inhalation: circulatory system, nervous system) | Danger | H370: Causes damage to organs (Inhalation: circulatory system, nervous system) |
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 ... |
Since carboxyhemoglobin increased into blood, the nervous system and the circulatory system were affected, and intelligence, athletic ability, hearings falled for humans and animals by inhalation exposure, it is classified into "Category 1." | |
9 | Specific target organ toxicity - Repeated exposure | Category 2 (Inhalation: heart, blood) | Warning | H373: May cause damage to organs through prolonged or repeated exposure (Inhalation: heart, blood) |
P260: Do not breathe dust/fume/gas/mist/vapours/spray. P314: Get medical advice/attention if you feel unwell. P501: Dispose of contents/container to ... |
In the repetitive inhalation experiment of the animal, effect was acknowledged in the heart and blood systems. Since exposure concentration was 50 to 250 ppm, it was classified to "Category 2." | |
10 | Aspiration hazard | Not applicable | - | - | - | - | Gas (GHS definition) |
