HEALTH HAZARDS
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: 2500 mg/kg REFERENCE SOURCE: IUCLID (2000)
1 Acute toxicity (Dermal) Classification not possible - - - - No data available
1 Acute toxicity (Inhalation: Gases) Not applicable - - - - Solid (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.
There was description that skin irritation was not admitted by the test using the rabbit (IUCLID (2000)). It was set to category 2 since there was description which suggests a potential of stimulating the human skin seriously (HSFS (2000)).
3 Serious eye damage/eye irritation Category 2A-2B 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.
It was set as Category 2A-2B from description that irritation was admitted by the test using the rabbit (UCLID (2000)). Since reparable is unknown, detailed categorization is not made.
4 Respiratory sensitization Classification not possible - - - - Although there is descriptive which suggests a possibility of causing asthmatic allergic to HSFS (2000), there is no report of a concrete case, and since data is insufficient, it cannot be classified.
4 Skin sensitization Classification not possible - - - - Although there is descriptive which suggests a possibility of causing skin allergy to HSFS (2000), there is no report of a concrete case, and since data is insufficient, it cannot classify.
5 Germ cell mutagenicity Classification not possible - - - - Since data is insufficient only the information of the data of the in vitro reverse mutation test, and it cannot be classified.
6 Carcinogenicity Classification not possible - - - - No data available
7 Reproductive toxicity Classification not possible - - - - No data available
8 Specific target organ toxicity - Single exposure Classification not possible - - - - Insufficient data available.
9 Specific target organ toxicity - Repeated exposure Classification not possible - - - - No data available
10 Aspiration hazard Classification not possible - - - - No data available

ENVIRONMENTAL HAZARDS

11 Hazardous to the aquatic environment (Acute) Category 3 - - H402: Harmful to aquatic life P273: Avoid release to the environment.
P501: Dispose of contents/container to ...
It was classified into Category 3 from 96-hour LC50=46-68mg/L of fishes (Golden orfe) (IUCLID, 2000).
11 Hazardous to the aquatic environment (Long-term) Not classified - - - - It is considered that toxicity factor is reduction of dissolved oxygen, but toxic effect was eased in environmental water.
