2 | Skin corrosion/irritation | Classification not possible |
- |
- | - | It is described in ACGIH (7th, 2012) that available data were not available to recommend a SKIN notation for this substance. And this substance is classified in "C; R34" in EU DSD classification and "Skin Corr. 1B H314" in EU CLP classification. Among the above information, by prioritizing the information in ACGIH (7th, 2012), the information source in List 1, it was classified as "Classification not possible." ACGIH, EU DSD classification, and EU CLP classification obtained in this investigation were added, and the classification was reviewed. | FY2013 | GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0)) |
3 | Serious eye damage/eye irritation | Category 2 |
Warning |
H319 | P305+P351+P338 P337+P313 P264 P280 |
It is described in DFGOT vol. 21 (2005) that this substance was irritating to the eye in rats and rabbits (no description on details). And it is described in HSDB (Access on September 2013) that this substance of 10-20 ppm can cause eye irritation in humans, and this substance of higher concentrations (described as vapour in HSDB) can cause eye injury. It was classified in Category 2 from the above information. Besides, it was classified in "C; R34" in EU DSD classification and "Skin Corr. 1B H314" EU CLP classification. DFGOT, HSDB, EU DSD classification, and EU CLP classification obtained in this investigation were added, and the classification was reviewed. | FY2013 | GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0)) |

5 | Germ cell mutagenicity | Classification not possible |
- |
- | - | It was classified as "Classification not possible" because it was not possible to classify a substance as "Not classified" according to the revised GHS classification guidance for the Japanese government. As for in vivo, it was negative in a chromosomal aberration test with mouse spermatocytes, a chromosomal aberration test with mouse peripheral blood lymphocytes, and a micronucleus test with mouse bone marrow cells (EHC 188 (1997), ACGIH (7th, 2012)). On the other hand, it was positive in a DNA damage test (DNA strand break) with mouse lung cells (EHC 188 (1997)), but the in-vivo effect was considered to be limited to the respiratory tract (DFGOT Vol. 21 (2005)). As for in vitro, it was negative in a gene mutation test with cultured mammalian cells (EHC 188 (1997)) and a micronucleus test with cultured human nasal epithelial cells (HSDB (Access on September 2013)), but there are positive results in a bacterial reverse mutation test, a chromosomal aberration test with cultured cells (EHC 188 (1997)), and a DNA damage test (comet assay) with cultured human nasal epithelial cells (HSDB (Access on September 2013)), and it was judged to be positive in vitro in DFGOT and ACGIH. | FY2013 | GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0)) |
6 | Carcinogenicity | Classification not possible |
- |
- | - | It was classified as "Classification not possible" because it was classified in A4 in ACGIH (7th, 2012). The category was changed according to the revised GHS classification guidance for the Japanese government. | FY2013 | GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0)) |
7 | Reproductive toxicity | Category 2 |
Warning |
H361 | P308+P313 P201 P202 P280 P405 P501 |
It was classified in Category 2 because it is described in EHC 188 (1997), DFGOT vol. 21 (2005) that clear reproductive toxicity (an increase in post-implantation lethality) was observed at the dose where general toxicity was seen in maternal animals in an inhalation test with rats exposed during gestation. | FY2013 | GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0)) |
8 | Specific target organ toxicity - Single exposure | Category 1 (respiratory organs), Category 3 (narcotic effects) |
Danger Warning |
H370 H336 |

In cases of humans exposed to this substance, it is described that effects on lung function and the respiratory organs were observed (ACGIH (7th, 2012), PATTY (6th, 2012), EHC 188 (1997)), and lung injury was permanent (ACGIH (7th, 2012)). Therefore, it was classified in Category 1 (respiratory system). And it was classified in Category 3 (narcotic effects) because somnolence and vertigo were found in humans (PATTY (6th, 2012)). As a result of investigating the updated information, effects were seen in the respiratory tract, larynx, bronchus, etc. in addition to the lung, therefore the target organs were changed to the respiratory system. And Category 3 (narcotic effects) was added because somnolence and vertigo were observed. | FY2013 | GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0)) |
9 | Specific target organ toxicity - Repeated exposure | Category 1 (lung, immune system) |
Danger |
H372 | P260 P264 P270 P314 P501 |
It was classified in Category 1 (lung) because it is described that long-tern exposure causes lung disease in humans (ACGIH (7th, 2001), EHC 188 (1997), PATTY (6th, 2012)), and the expansion of the alveoli was observed at the concentration (0.5 ppm) within the guidance value range for Category 1 after repeated inhalation exposure in mice for 3-12 months (ACGIH (7th, 2001)). Furthermore, from the description that in a test in which monkeys were exposed by inhalation at 5 ppm for 2 months or at 10 ppm for 1 month, mortality from infection of bacteria (Klebsiella pneumoniae) or influenza virus increased in the exposed groups, and a marked decrease in resistance to infections was found (the original article (Henry, M.C. et al. (1970)) quoted in ACGIH (7th, 2001) was obtained, and the content was confirmed), and the description that in a 6-month inhalation test with rats exposed at 1 ppm, decreased levels of all serum immunoglobulins and complements were observed (EHC 188 (1997)), it is pointed out that long-term inhalation exposure to this substance may cause a decrease in host defenses in the respiratory system or immunosuppression in humans (PATTY (6th, 2012), EHC 188 (1997)). Therefore, Category 1 (immune system) was added from the animal test results. | FY2013 | GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0)) |
