Danger |
H331 | P304+P340 P403+P233 P261 P271 P311 P321 P405 P501 |
From reported LC50 values (4 hours) of 590 ppm and 1,082 ppm for rats (ACGIH (7th, 2012)), it was classified in Category 3. |
1 | Acute toxicity (Inhalation: Vapours) | Not applicable |
- |
- | - | "Gases" according to GHS definition. |
1 | Acute toxicity (Inhalation: Dusts and mists) | Not applicable |
- |

2 | Skin corrosion/irritation | Classification not possible |
- |
- | - | Due to lack of data, the classification is not possible. |
3 | Serious eye damage/eye irritation | Classification not possible |
- |
- | - | Due to lack of data, the classification is not possible. |
4 | Respiratory sensitization | Classification not possible |
- |
- | - | Due to lack of data, the classification is not possible. |
4 | Skin sensitization | Classification not possible |
- |
- | - | Due to lack of data, the classification is not possible. |
5 | Germ cell mutagenicity | Classification not possible |
- |
- | - | The classification is not possible due to lack of data. No in vivo data. As for in vitro, it is reported that a bacterial reverse mutation test was weakly positive (NTP DB (Access on June 2015)). |
6 | Carcinogenicity | Classification not possible |
- |
- | - | Due to no classification result by other organization and lack of data, the classification is not possible. |
7 | Reproductive toxicity | Classification not possible |
- |
- | - | The classification is not possible due to lack of data. Besides, it is written that a decreased pregnancy rate was observed in a test in which male rats were mated with unexposed females after inhalation exposure for ten weeks (draft ATSDR (2014)). |
8 | Specific target organ toxicity - Single exposure | Category 1 (central nervous system) |
Danger |
H370 | P308+P311 P260 P264 P270 P321 P405 P501 |
There is not many pieces of information on this substance. However, in inhalation exposure in rats (not less than 1,096 ppm), central nervous system disorder such as convulsions, hypoactivity, and dyspnea was reported. It is written that principal target organ in acute toxicity is the brain, especially cerebellum, and central nervous system is affected by acute exposure (ACGIH (7th, 2012), HSDB (Access on June 2015), draft ATSDR (2014)). The doses in the above inhalation exposure in rats correspond to Category 1 in Guidance values. Therefore, the substance was classified in Category 1 (central nervous system). |
9 | Specific target organ toxicity - Repeated exposure | Category 2 (central nervous system) |
Warning |
H373 | P260 P314 P501 |
There is no information in humans. As for experimental animals, in a 12-week inhalation toxicity test using rats, the following effects on the central nervous system were observed: decreases in cytochrome oxidase activity at 200 ppm (converted to a Guidance value equivalent: 133.3 ppm) or higher (week 3,6,12); and decreased brainstem auditory-evoked potential at 300 ppm (converted to a Guidance value equivalent: 200 ppm) or above. These doses are within the range of Category 2. Besides, changes in functional observation battery (FOB) and latency of somatosensory-evoked potentials, a histopathological change, and changes in magnetic resonance microscopy (MRM) (multiple hypointense areas in posterior thalamic nuclear group, hypothalamus, and posterior colliculus) were observed at 400 ppm (converted to a Guidance value equivalent: 266.7 ppm) that is the dose above Category 2 (ACGIH (7th, 2012)). Therefore, the substance was classified in Category 2 (central nervous system). |
