Danger |
H330 | P304+P340 P403+P233 P260 P271 P284 P310 P320 P405 P501 |
Based on reports of LC50 values of 2.4 ppm (ACGIH (7th, 2001)), 22.4 ppm (DFGOT vol. 9 (1998)) for rats, this substance was classified in Category 1. Besides, since the LC50 values were lower than 90% of the saturated vapor pressure concentration (123,552 ppm), a reference value in the unit of ppm was applied as vapor without mist. |

There is a report that in a skin irritation test with rabbits, as the result of application of undiluted 0.2 mL solution of this substance, hyperemia, oedema, ulcers, and scar formation were observed, and resolving of symptoms required 28 to 30 days (DFGOT Vol. 9 (1998)). In addition, there is a report that in another test with rabbits, at 1.5 and 15 minutes after application of this substance, severe inflammation was observed, severe necrosis leading to the skin tissue and muscle tissue was observed, and recovery property was not observed (DFGOT Vol. 9 (1998)). Moreover, there are descriptions that this substance shows severe irritation to human skin (ACGIH (7th, 2001)), and it shows corrosivity (DFGOT Vol.9 (1998)). From the above, this substance was classified in Category 1. |

H318 | P305+P351+P338 P280 P310 |
There is a report that in an eye irritation test with rabbits, as the result of application of one drop of this substance, severe damage was observed, and loss of vision occurred (DFGOT Vol. 9 (1998)). In addition, there are descriptions that this substance shows severe irritation to human eyes (ACGIH (7th, 2001)), and it shows corrosivity (DFGOT Vol.9 (1998)). This substance was classified in Category 1 for skin corrosion/irritation. From the above, this substance was classified in Category 1. |

- | - | As for in vivo, a micronucleus test with the bone marrow cells of male rats gave an equivocal result, and the results of micronucleus test with mouse peripheral blood were negative in females and equivocal in males (NTP DB (Access on October 2015)). As for in vitro, there are positive and negative results in bacterial reverse mutation tests (DFGOT Vol. 9 (1998), ACGIH (7th, 2001), NTP DB (Access on October 2015)). Because there were no clear positive findings in in-vivo tests, it was classified as "Classification not possible" according to the GHS Classification Guidance for the Japanese Government. |
| 6 | Carcinogenicity | Classification not possible |
- |
- | - | There was no classification result by other organizations. Therefore, classification was not possible to due to lack of data. |
| 7 | Reproductive toxicity | Classification not possible |

 Danger Warning |
H370 H336 |
P308+P311 P260 P264 P270 P321 P405 P501 P304+P340 P403+P233 P261 P271 P312 |
This substance has respiratory tract irritating potential and narcotic effects in humans (ACGIH (7th, 2001), DFGOT Vol. 9 (1998)). As for experimental animals, there are reports of effects on the respiratory organs (severe damage in the respiratory tract mucosa, and pulmonary oedema) by inhalation exposure (corresponding to Category 1) of rats, mice, and guinea pigs, and severe kidney damage (details were unknown) by oral administration (corresponding to Category 1) to rabbits and cats (DFGOT Vol. 9 (1998), BUA 233 (2003)). From the above, this substance has effects on the respiratory organs and kidney in addition to narcotic effects, and it was classified in Category 1 (respiratory organs, kidney), Category 3 (narcotic effects). |
| 9 | Specific target organ toxicity - Repeated exposure | Category 1 (respiratory organs) |
Danger |
H372 | P260 P264 P270 P314 P501 |
There is no adverse information on repeated exposure in humans. As for experimental animals, there is a report that in the tests in which rats and mice were exposed 12 times by inhalation to 1 ppm of this substance, damage in the upper respiratory tract was observed in both species, and no effects was observed at 0.5 ppm (BUA 233 (2003)). Also, there is a description that in a test where rats were exposed by inhalation to 6.9 ppm of this substance for 2.5 months, dyspnea was observed (DFGOT Vol. 9 (1998)). Therefore, the respiratory organs were considered as the target organ in the inhalation route. The converted guidance concentration as exposure by vapor was calculated to be 0.00038, 0.0011 mg/L/6 hr, respectively, and they correspond to Category 1. Therefore, it was classified in Category 1 (respiratory organs) for this hazard class. |
| 10 | Aspiration hazard | Classification not possible |
- |
- | - | There is no case of aspiration hazard in humans. However, this substance belongs to ketones composed of carbon atoms of 3 or more and not more than 13, and the calculated kinematic viscosity value is 0.934 mm2/sec (21/20 deg C) based on the numerical data listed in HSDB (Access on August 2015) (viscosity: 0.807 mPa*s (21 deg C), density (specific gravity): 0.8636 (20 deg C)). From the above, it corresponds to Category 2 in the UN GHS classification, but it was classified as "Classification not possible" according to the current GHS classification guidance for the Japanese Government revised after the previous classification. |
