Based on two reports of the epidemiologic survey that in the mouse inhalation study, bone marrow chromosomal aberration and induction of micronuclei were acknowledged (RTECS, 2004) and that the occurrence frequency of the chromosome aberration was high in the exposured human peripheral blood lymphocyte (in vivo somatic cell information) (HSDB 2005), we categorized it as Category 2. | |
6 | Carcinogenicity | Classification not possible | - | - | - | - | In male and female rats and mice, pheochromocytoma to the adrenal gland and slight increases of adenoma to the pancreas is reported only in the male rats(HSDB (2005)). However, it could not be said to be sufficient evidence for a classification, and it was presupposed that it cannot be classified. |

In the reference (Schardein JL, Chemically induced Birth Defects-3rd edition, Marcel Dekker, New York, 2000) indicated to the technological direction, stillbirth and the abnormal children's delivery are reported as a result of the environmental emmision of this products in Indian plant's incident in 1984. However, it is supposed that an epidemiological study is still more required. Since only the information applicable to Category 1A was not acquired, and it was classified into the Category 1B. In addition, it was reported the increase embryo resorption at dose not affecting maternal body weight in pregnant rat inharation exposure (RTECS (2004)). | |

Since there is a report of pulmonary edemas, dyspnea, respiratory distress syndrome etc. by humans (ACGIH (2001), HSDB (2005)) and irritation to the human nose and throat has been reported as well (ACGIH (2001)), it was set as Category 1 (respiratory tracts). | |
9 | Specific target organ toxicity - Repeated exposure | Classification not possible | - | - | - | - | Since any report were the short administration period and insufficient data, it cannot be classified. |
10 | Aspiration hazard | Classification not possible | - | - | - | - | No data available |
Hazard class | Classification | Symbol | Signal word | Hazard statement | Precautionary statement | Rationale for the classification | |
