HEALTH HAZARDS
Hazard class Classification Symbol Signal word Hazard statement Precautionary statement Rationale for the classification
1 Acute toxicity (Oral) Not applicable - - - - Gas (GHS definition)
1 Acute toxicity (Dermal) Not applicable - - - - Gas (GHS definition)
1 Acute toxicity (Inhalation: Gases) Not classified - - - - It was considered as the outside of Category based on mouse LC50 (2 hours): >500000ppm (4 hour equivalent: >353553ppm) (RTECS, Access on Aug 2005).
1 Acute toxicity (Inhalation: Vapours) Not applicable - - - - Gas (GHS definition)
1 Acute toxicity (Inhalation: Dusts and mists) Not applicable - - - - Gas (GHS definition)
2 Skin corrosion/irritation Not classified - - - - From the description that the skin is not stimulated in ACGIH (7th, 2001), it carried out the outside of category.
3 Serious eye damage/eye irritation Not classified - - - - From description that the eye is not stimulated (ACGIH (7th, 2001)), it was set as the outside of Category.
4 Respiratory sensitization Classification not possible - - - - No data available
4 Skin sensitization Classification not possible - - - - No data available
5 Germ cell mutagenicity Classification not possible - - - - Classification not possible due to lack of data
6 Carcinogenicity Classification not possible - - - - No data available
7 Reproductive toxicity Classification not possible - - - - Classification not possible due to lack of data
8 Specific target organ toxicity - Single exposure Not classified - - - - From description in ACGIH (7th, 2001) and PATTY (4th, 1994) that it has no hazard, and it was considered as the outside of Category.
9 Specific target organ toxicity - Repeated exposure Not classified - - - - Based on description that there is no hazard (ACGIH (7th, 2001) and PATTY (4th, 1994)), it was carried out the outside of Category.
10 Aspiration hazard Not applicable - - - - Gas (GHS definition)
