2 | Skin corrosion/irritation | Category 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 ... |
Since it has corrosivity on skin (ICSC (1997)) is very irritating to damp skin (ACGIH (2001)), and is designated to UN classification class 8-III, it was classified into Category 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. |
It categoried into Category 1 based on the corrosive to eye (ICSC (1997)), and corrosion of the skin / stimulative GHS classification being Category 1C. | |
4 | Respiratory sensitization | Classification not possible | - | - | - | - | Since there is no data, it cannot be classified. |
4 | Skin sensitization | Not classified | - | - | - | - | It was put outside of the Category according to the negative statement(IUCLID (2000)) of a test in humans. |
5 | Germ cell mutagenicity | Classification not possible | - | - | - | - | We found the description that it gave negative result in mitotic recombination tests by yeast cells, and it gave negative in the Ames examination (IUCLID (2000)). However, we found no in vivo results and we pressuposed we could not classify it. |
6 | Carcinogenicity | Classification not possible | - | - | - | - | Classification not possible due to lack of data and reports |
7 | Reproductive toxicity | Classification not possible | - | - | - | - | It was considered that it cannot be classified because of insufficient data although it was described "no effects" in one-generation test of rats and mice (IUCLID (2000)). |
8 | Specific target organ toxicity - Single exposure | Category 1 (respiratory system), Category 2 (systemic toxicity, digestive system) |
Danger Warning |
H370: Causes damage to organs (respiratory system) H371: May cause damage to organs (systemic toxicity, digestive 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 ... P309+P311: IF exposed or if you feel unwell: Call a POISON CENTER or doctor/physician. |
There is a statement that the inflammation of a respiratory tract (ACGIH (2001)) and pneumonitis (HSDB (2005)) are caused from dust inhalation and it was set as category 1 (respiratory systems), and if it drinks by mistake, a pulse will be quick and will become weak, breathing is quick and becomes shallow, body temperature falls, it becomes difficult to breathe by cancer of glottis, and will be in a shock states. There is the description which also produces esophageal, the stomach perforation (HSDB (2005)), but it was Priority2, it classified into Category 2 (whole body toxicity, digestive organ). | |
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 ... |
It was classified into Category 1 (respiratory systems) according to the statement of ulcers and perforations of nasal septum (ACGIH (2001)), and (ICSC (1997)). | |
10 | Aspiration hazard | Category 1 | Danger | H304: May be fatal if swallowed and enters airways |
P301+P310: IF SWALLOWED: Immediately call a POISON CENTER or doctor/physician. P331: Do NOT induce vomiting. P405: Store locked up. P501: Dispose of contents/container to ... |
Category 1 because of "aspiration pneumonia to human beings."(HSDB, 2005) |
Hazard class | Classification | Symbol | Signal word | Hazard statement | Precautionary statement | Rationale for the classification | |
---|---|---|---|---|---|---|---|
11 | Hazardous to the aquatic environment (Acute) | Not classified | - | - | - | - | It carried out the outside of Category from 96-hour LC50=1070mg/L of fishes (Carp) (IUCLID, 2000). |
11 | Hazardous to the aquatic environment (Long-term) | Not classified | - | - | - | - | Since not water-insoluble (water solubility=1200mg/L(HSDB, 2004)) and acute toxicity is low. |
