As a result of the examination using water solutions, based on rat LD50 value: 698mg/kg (ACGIH (7th, 2001), DFGOT vol.7 (1996)), it was set as Category 4. (water solutions)
1 Acute toxicity (Dermal) Classification not possible - - - - No data available

There are descriptions that in 3 or 6% aqueous solutions skin application test on rabbits, erythema and edema, and following ulcer was observed of the skin (DFGOT vol.7, 1996, ACGIH, 7th, 2001) and that the test inwhich the tip of mice tail was dipped in 6% aqueous solutions for 2 hours, congestion with a clear boundary and following tissue necrosis was observed (DFGOT vol.7, 1996, ACGIH, 7th, 2001). It was judged to have corrosivity and was classified as Category 1A-1C (3-6% aqueous solutions). Since the details of development and course of the corrosive reaction were unknown, it was not subcategorized.
3 Serious eye damage/eye irritation Category 1 (1-5% solution) Danger H318: Causes serious eye damage (1-5% solution) P305+P351+P338: IF IN EYES: Rinse cautiously with water for several minutes. Remove contact lenses, if present and easy to do. Continue rinsing.
P280: Wear protective gloves/protective clothing/eye protection/face protection.
P310: Immediately call a POISON CENTER or doctor/physician.
To eye of rabbit, conjunctivitis, conjunctival edemas, keratitis and corneal opacity are caused 1% aqueous solution, and conjunctival hemorrhage, corneal edemas, turbidity and neovascularization are caused 5% aqueous solution, and it will continue 28 days. Furthermore, in higher concentrations, skin corrosiveness that a corneal becomes the translucent of blue and white in several seconds (DFGOTvol.7 (1996), ACGIH 7th, (2001)). So it was set as Category 1 (1-5% water).
4 Respiratory sensitization Classification not possible - - - - No data
4 Skin sensitization Category 1 Warning H317: May cause an allergic skin reaction P302+P352: IF ON SKIN: Wash with plenty of soap and water.
P333+P313: If skin irritation or rash occurs: Get medical advice/attention.
P261: Avoid breathing dust/fume/gas/mist/vapours/spray.
P272: Contaminated work clothing should not be allowed out of the workplace.
P280: Wear protective gloves/protective clothing/eye protection/face protection.
P321: Specific treatment (see ... on this label).
P363: Wash contaminated clothing before reuse.
P501: Dispose of contents/container to ...
In Maximization test (closed epicutaneous test) using a guinea pigs, it is positive (the rate of positivity: 100%) (DFGOTvol.7 (1996)) and, as a description states that this substance has skin sensitization (ACGIH 7th, 2001), it was referred to as Category 1.
5 Germ cell mutagenicity Not classified - - - - Although there are no data from the tests in germ cells, the report of the negative result of the in vivo chromosome aberration test using bone-marrow cells taken from rats that have been subjected to exposure to this substance for 3 months through inhalation (DFGOTvol.7 (1996)). So the substance was regarded as outside the categories.
6 Carcinogenicity Not classified - - - - Since it was classified into A4 according to ACGIH (7th, 2001), it carried out the outside of Category.
7 Reproductive toxicity Classification not possible - - - - Classification not possible due to lack of data
8 Specific target organ toxicity - Single exposure Category 1 (central nervous system, respiratory system) Danger H370: Causes damage to organs (central nervous system, respiratory system) P307+P311: IF exposed: Call a POISON CENTER or doctor/physician.
P260: Do not breathe dust/fume/gas/mist/vapours/spray.
P264: Wash ... thoroughly after handling.
P270: Do not eat, drink or smoke when using this product.
P321: Specific treatment (see ... on this label).
P405: Store locked up.
P501: Dispose of contents/container to ...
Due to the descriptions that the tissue injury is observed in respiratory mucosa by the exposure concentrations at 600ppm or more by single inhalation exposure test in rats (PATTY (5th, 2001)), that the RD50 value in short time inhalation exposure in rat and mouse (50% breathing rates inhibitory concentration) is calculated (DFGOTvol.7 (1996)), that it has respiratory irritantation, and that the central nervous system effects (incoordination and depressomotor) were observed in the dosage of the guidance value of Category 1in the oral administration examination in rat, mouse, rabbit, and guinea pig (ACGIH (7th, 2001)). So it was classified into Category 1(central nervous system, respiratory system).
9 Specific target organ toxicity - Repeated exposure Category 1 (respiratory system) Danger H372: Cause damage to organs through prolonged or repeated exposure (respiratory system) P260: Do not breathe dust/fume/gas/mist/vapours/spray.
P264: Wash ... thoroughly after handling.
P270: Do not eat, drink or smoke when using this product.
P314: Get medical advice/attention if you feel unwell.
P501: Dispose of contents/container to ...
In the inhalation exposure test in rats and mice for two years, it was classified to as Category 1 (respiratory systems) from the description that inflammation, denaturation, and hyperplastic injury at the rhinal mucosas were acknowledged in the exposure group of 50 ppm or more of the guidance value range maximum of Category 1(ACGIH (7th, 2001), DFGOT vol.7 (1996), PATTY (5th, 2001)).
10 Aspiration hazard Not applicable - - - - Gas (GHS definition)

It was classified into Category 2 from 96-hour EC50=6200microg/L of algae (Selenastrum) (AQUIRE, 2003).
11 Hazardous to the aquatic environment (Long-term) Not classified - - - - Since rapidly degrading (BOD: 88% (existing chemical safety inspections data)), and less bio-accumulative (log Kow=-0.38 (PHYSPROP Database, 2005)).
