Hazard class | Classification | Symbol | Signal word | Hazard statement | Precautionary statement | Rationale for the classification | |
---|---|---|---|---|---|---|---|
1 | Acute toxicity (Oral) | Category 5 | - | Warning | H303: May be harmful if swallowed | P312: Call a POISON CENTER or doctor/physician if you feel unwell. | SPECIES: Rat ENDPOINT: LD50 VALUE: 3200 mg/kg REFERENCE SOURCE: SIDS (2002) |
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 2 | Warning | H315: Causes skin irritation |
P302+P352: IF ON SKIN: Wash with plenty of soap and water. P332+P313: If skin irritation occurs: Get medical advice/attention. P264: Wash ... thoroughly after handling. P280: Wear protective gloves/protective clothing/eye protection/face protection. P321: Specific treatment (see ... on this label). P362: Take off contaminated clothing and wash before reuse. |
From description that it is advanced stimulativeness at the skin of the rabbit (SIDS (2002)), it was set as Category 2. | |
3 | Serious eye damage/eye irritation | Category 2A | Warning | H319: Causes serious eye irritation |
P305+P351+P338: IF IN EYES: Rinse cautiously with water for several minutes. Remove contact lenses, if present and easy to do. Continue rinsing. P337+P313: If eye irritation persists: Get medical advice/attention. P264: Wash ... thoroughly after handling. P280: Wear protective gloves/protective clothing/eye protection/face protection. |
Based on the description that it had severe stimulativeness on the eyes of the rabbits (SIDS (2002)), we classified it as Category 2A. | |
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 | Not classified | - | - | - | - | It was considered as out of Category based on the description that specific reproductive toxicity was not observed at the dose in which general toxicity is observed in parental animals in the reproductive and developmental toxicity studies using the rat (the Health, Labor and Welfare Ministry reports (2005), SIDS (2002)). |
8 | Specific target organ toxicity - Single exposure | Category 3 (Respiratory tract irritation, Narcotic effects) | Warning |
H335: May cause respiratory irritation (respiratory tract irritation, narcotic effects) H336: May cause drowsiness or dizziness (respiratory tract irritation, narcotic effects) |
P304+P340: IF INHALED: Remove victim to fresh air and keep at rest in a position comfortable for breathing. P403+P233: Store in a well-ventilated place. Keep container tightly closed. P261: Avoid breathing dust/fume/gas/mist/vapours/spray. P271: Use only outdoors or in a well-ventilated area. P312: Call a POISON CENTER or doctor/physician if you feel unwell. P405: Store locked up. P501: Dispose of contents/container to ... |
It was judged that the substance had temporary affect on the nervous system and airway irritant properties, and it was classified as Category 3 (airway irritant, anesthetic properties). Because there were reports of decrease in locomotor activity, deep respiration and eyelid ptosis in an oral administration test using rats (MHLW report (2005)), and of irritation to airways and headaches in occupational exposure cases (ACGIH (7th, 2001)). | |
9 | Specific target organ toxicity - Repeated exposure | Category 2 (urinary bladder, liver, adrenal gland) | Warning | H373: May cause damage to organs through prolonged or repeated exposure (urinary bladder, liver, adrenal gland) |
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 ... |
We classified it into Category 2 (a bladder, liver, adrenal gland) based on the description that in the oral study using the rat, the effect on a bladder (hyperplasia of the epithelium accompanied with degeneration of bladder mucosa), liver (hepatocyte fatty changes) and the adrenal gland (increase of the vacuole in an adrenocortical cell) was observed with the dose of the guidance value range of Category 2 (the Health, Labor and Welfare Ministry reports (2005) and SIDS (2002)). | |
10 | Aspiration hazard | Classification not possible | - | - | - | - | No data available |
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=110mg/L of fishes (Oryzias latipes) (SIDS, 2004). |
11 | Hazardous to the aquatic environment (Long-term) | Not classified | - | - | - | - | Since not water-insoluble (water solubility=17190mg/L(PHYSPROP Database, 2005)) and acute toxicity is low. |
