On the basis of an LC50 value for rats: 138 ppm in a 4-hour exposure (OECD TG 403; GLP) (IUCLID (2000)), it was classified in Category 2.
Besides, a reference value of gasses as a vapour with hardly included mist was applied because the LC50 value (138 ppm) is lower than 90 % of the saturated vapour pressure concentration (3868 ppm).
1 Acute toxicity (Inhalation: Dusts and mists) Classification not possible - - - No data.

On the basis of a "highly irritating" result in an occlusive test applied to rabbit skins for 4 hours (US-EPA-TSCA Health Effects Testing Guidelines and US-EPA-FIFRA, Pesticide Assessment Guidelines; GLP compliance) (IUCLID (2000)), it was classified in Category 2.
Besides, details of a test which reported that an occlusive application to rabbit auricular skins for 1 to 8 hours resulted in corrosive (IUCLID (2000)) are unknown.
3 Serious eye damage/eye irritation Category 2

Warning

On the basis that a test using rabbit reported highly irritating (IUCLID (2000)), it was classified in Category 2.
4 Respiratory sensitization Classification not possible - - - No data.
4 Skin sensitization Classification not possible - - - No data.
5 Germ cell mutagenicity Classification not possible - - - No data.
6 Carcinogenicity Classification not possible - - - No data.
7 Reproductive toxicity Classification not possible - - - No data.
8 Specific target organ toxicity - Single exposure Classification not possible - - - No data.
9 Specific target organ toxicity - Repeated exposure Category 1 (respiratory tract)

In a 4-week inhalation (vapour) exposure test in rats (OEDD TG 412; GLP), the test substance caused respiratory tract irritation symptoms at a concentration of 0.1083 mg/L/6h (converted to a 90-day equivalent value: 0.033 mg/L/6h) such as bradypnea, labored breathing, rale, cyanosis, serous nasal discharge. And pathological signs such as inflammatory changes with a wide area of metaplasia of flat epithelium accompanied by partial cornification complicated by the invasion of round cells in the nasal cavity, paranasal cavity, oropharynx, nasopharynx, pharynx and respiratory tract, and atrophy of olfactory epithelium were reported. And the number of animals with slightly significant subpleural round cell invasion increased slightly. (IUCLID (2000))
Due to the main effects on a nose, oropharynx, pharynx and respiratory tract, and no serious effects on the lung, and the exposure concentration corresponding to Category 1 of a range of Guidance values, it was classified in Category 1 (respiratory tract).
10 Aspiration hazard Classification not possible - - - No data.
