1 Acute toxicity (Oral) Category 4 Warning H302: Harmful if swallowed P301+P312: IF SWALLOWED: Call a POISON CENTER or doctor/physician if you feel unwell.
P264: Wash ... thoroughly after handling.
P270: Do not eat, drink or smoke when using this product.

Rat LD50 value: 880mg/kg (CERI Hazard Data, 1996, DFGOT vol.20, 2003), 350mg/kg (DFGOT vol.20, 2003), 350-1000mg/kg (IARC 54, 1992). Calculated based on the data above. Since the calculated values was 539.2mg/kg, it was classified to category 4.
1 Acute toxicity (Dermal) Category 3 Danger H311: Toxic in contact with skin P302+P352: IF ON SKIN: Wash with plenty of soap and water.
P280: Wear protective gloves/protective clothing/eye protection/face protection.
P312: Call a POISON CENTER or doctor/physician if you feel unwell.
P322: Specific treatment (see ... on this label).
P361: Remove/Take off immediately all contaminated clothing.
P363: Wash contaminated clothing before reuse.
P405: Store locked up.

It was set as Category 3 based on rabbit LD50 value: 708mg/kg (CERI Hazard Data, 1996) and 600mg/kg (DFGOT vol.20, 2003, IARC 54, 1992).
1 Acute toxicity (Inhalation: Gases) Not applicable - - - - Liquid (GHS definition)
1 Acute toxicity (Inhalation: Vapours) Classification not possible - - - - There is description that death was not observed with rat 4-hour exposure to 250ppm (equivalent 1.57mg/L) in the inhalation exposure test (DFGOT (vol.20, 2003)). but there was no other exposure data to vapor, and since Category could not be specified only with this data. So it cannot be classified due to data insufficiency.
1 Acute toxicity (Inhalation: Dusts and mists) Classification not possible - - - - There is description that the example of all six rats died within 14 days by 500ppm 4-hour exposure (equivalent 3.15 mg/L) in the inhalation exposure test (DFGOT (vol.20, 2003)). But there was no other exposure data in mists and the category could not be specified only by this data. Therefore, it cannot be classified since data is insufficient.
2 Skin corrosion/irritation Category 1A-1C Danger H314: Causes severe skin burns and eye damage P301+P330+P331: IF SWALLOWED: Rinse mouth. Do NOT induce vomiting.
P303+P361+P353: IF ON SKIN (or hair): Remove/Take off immediately all contaminated clothing. Rinse skin with water/shower.
P305+P351+P338: IF IN EYES: Rinse cautiously with water for several minutes. Remove contact lenses, if present and easy to do. Continue rinsing.
P304+P340: IF INHALED: Remove victim to fresh air and keep at rest in a position comfortable for breathing.
P260: Do not breathe dust/fume/gas/mist/vapours/spray.
P264: Wash ... thoroughly after handling.
P280: Wear protective gloves/protective clothing/eye protection/face protection.
P310: Immediately call a POISON CENTER or doctor/physician.
P321: Specific treatment (see ... on this label).
P363: Wash contaminated clothing before reuse.
P405: Store locked up.
P501: Dispose of contents/container to ...
From description that the necrosis arose by application on the skin of the rabbit (CERI Hazard Data (1996) and DFGOT (vol.20, 2003)), it was judged that there was caustic and it was set as Category 1A-1C.
3 Serious eye damage/eye irritation Category 1 Danger H318: Causes serious eye damage 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.
Since it had skin corrosiveness, it was classified as Category 1.

Since there is a positive result (IARC 71, 1999; DFGOT vol.20, 2003) by the dominant lethal test using the mouse which is the in vivo multigeneration mutagenicity test using a germ cell, it is set as Category 1B.
6 Carcinogenicity Category 1B Danger H350: May cause cancer P308+P313: IF exposed or concerned: Get medical advice/attention.
P201: Obtain special instructions before use.
P202: Do not handle until all safety precautions have been read and understood.
P281: Use personal protective equipment as required.
P405: Store locked up.
P501: Dispose of contents/container to ...
Since it was classified into group 2A (IARC 71, 1999)in IARC, 2A in Japan Assoc. of Industrial Health (industrial hygene academic society recommentation, 2005), category 2 (EU-Annex I, 2006) in 2005 in EU and R (NTP RoC 11th, 2005) in NTP, it was considered as Category 1B.
7 Reproductive toxicity Classification not possible - - - - No data available
8 Specific target organ toxicity - Single exposure Category 2 (respiratory system) Warning H371: May cause damage to organs (respiratory system) P309+P311: IF exposed or if you feel unwell: 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.
P405: Store locked up.
P501: Dispose of contents/container to ...
Although there are no specific case reports, the substance was classified as Category 2 (respiratory organs). Because it is reported in ICSC (J) (1999) and SITTIG (4th, 2002) that it has irritant and corrosive properties to airways, and that the inhalation of the aerosol substance form may cause pulmonary edema.
9 Specific target organ toxicity - Repeated exposure Classification not possible - - - - No data available
10 Aspiration hazard Classification not possible - - - - No data available

It was classified into Category 3 from 96-hour LC50=20mg/L of fishes (Rainbow trout) (IUCLID, 2000).
11 Hazardous to the aquatic environment (Long-term) Not classified - - - - Since rapidly degrading (BOD: 69% (existing chemical safety inspections data)), and less bio-accumulative (log Kow=1.14 (PHYSPROP Database, 2005)).
