Category 4 based on SPECIES: Rat; ENDPOINT: LD50; VALUE: 430 mg/kg; REFERENCE SOURCE: RTECS(2000), HSDB(2004)
1 Acute toxicity (Dermal) Classification not possible - - - - No data available
1 Acute toxicity (Inhalation: Gases) Not applicable - - - - Liquid (GHS definition)
1 Acute toxicity (Inhalation: Vapours) Classification not possible - - - - No data available
1 Acute toxicity (Inhalation: Dusts and mists) Classification not possible - - - - No data available
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.

Since there was description of "corroding the skin" to humans (ICSC (2004), SITTIG (4th, 2002)), and was also classified into "C;R34 (Causes burns)" of European risk phrases, it was set as category 1A-1C. [view] It is more desirable to be set as 1A from a viewpoint of safety, when further categorizing needs to be performed.
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.
There is description which indicates caustic to the human eye (ICSC(2004), SITTIG(4th, 2002)), and it causes corrosive also to the skin. So it is set as Category 1.
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 - - - - No data available
8 Specific target organ toxicity - Single exposure Category 2 (respiratory system (inhalation), digestive system, central nervous system) Warning H371: May cause damage to organs (respiratory system (inhalation), digestive system, central nervous 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 ...
Since there was a description of Priority 2 to the humans (caustic is indicated to an air passages. And pulmonary edemas may be caused by breathing vapors (ICSC (2004)), it has serious irritant in lungs, a nose, and a throat, it brings a severe obstacle in the throat and the stomach (HSDB (2004)), breathing difficulty, vomiting, nausea etc. by inhalation, and the burning sensations, the pain of a throat and an alimentary canal, a tremor, a spasm of abdominal in oral (SITTIG (4th, 2002)), and the stimulus to the skin and a respiratory tract and headache in accidental spillage from a tank car (HSDB (2004)), this product caused mild gastroenteritis by drinking the tap water which superfluous mixing (IUCLID (2000)), so it was considered as Category 2 (the respiratory systems (inhalation), digestive systems, central nervous systems).
9 Specific target organ toxicity - Repeated exposure Category 2 (tooth/bone, respiratory system) Warning H373: May cause damage to organs through prolonged or repeated exposure (tooth/bone, respiratory system) P260: Do not breathe dust/fume/gas/mist/vapours/spray.
P314: Get medical advice/attention if you feel unwell.
P501: Dispose of contents/container to ...
Based on description on the humans of Priority 2 (bone change, the mucosal corrosivity effects (nose,throat,bronchial), pneumonia, etc. occured in long-term exposure (HSDB (2004)), and bone and tooth are affected, and fluorosis may be occured (ICSC (2004))), it was classified into Category 2 (tooth/bone,respiratory systems).
10 Aspiration hazard Classification not possible - - - - No data available
