HEALTH HAZARDS
Hazard class Classification Symbol Signal word Hazard statement Precautionary statement Rationale for the classification
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.
P330: Rinse mouth.
P501: Dispose of contents/container to ...
Based on the rat LD50 (oral route) value of 1,644mg/kg (Agricultural Chemical Registration Data (1984)).
1 Acute toxicity (Dermal) Not classified - - - - Based on the rat LD50 (dermal route) value of >5,000mg/kg (Agricultural Chemical Registration Data (1984)).
1 Acute toxicity (Inhalation: Gases) Not applicable - - - - Due to the fact that the substance is a solid according to the GHS criteria and inhalation of its gas is not expected.
1 Acute toxicity (Inhalation: Vapours) Classification not possible - - - - No data available
1 Acute toxicity (Inhalation: Dusts and mists) Classification not possible - - - - Classification cannot be determined, though the available rat inhalation study reported the LC50 value of >0.28mg/L (Agricultural Chemical Registration Data (1984)).
2 Skin corrosion/irritation Not classified - - - - Based on no evidence of irritation observed in rabbit skin irritation tests (Agricultural Chemical Registration Data (1984)).
3 Serious eye damage/eye irritation Category 2B - Warning H320: Causes 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.
Based on the evidence of mild irritation reactions which were fully reversed within 3 days, observed in rabbit eye irritation tests (Agricultural Chemical Registration Data (1984)).
4 Respiratory sensitization Classification not possible - - - - No data available
4 Skin sensitization Not classified - - - - No skin sensitizing potential was found in guinea pig sensitization tests employing the Buehler method (Agricultural Chemical Registration Data (1989)).
5 Germ cell mutagenicity Not classified - - - - Based on negative data in micronucleus tests on mouse bone marrow cells, though in vitro reverse mutation tests showed negative whereas in vitro chromosome aberration tests gave false positive results (Agricultural Chemical Registration Data (1984, 1989, 1992)).
6 Carcinogenicity Not classified - - - - There was no evidence of treatment-related incidence of tumor formation observed in rat/mouse carcinogenicity studies (Agricultural Chemical Registration Data (1984)).
7 Reproductive toxicity Not classified - - - - Based on no evidence of adverse effects on parental reproduction and offspring development observed in rat 2-generation reproduction studies and rat/rabbit teratogenicity studies (Agricultural Chemical Registration Data (1989)).
8 Specific target organ toxicity - Single exposure Category 2 (nervous system) Warning H371: May cause damage to organs (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 ...
Based on the evidence from animal studies including "tetraplegia," "reduced activity," "staggering," "lacrimation," "blood-like gum along the lid-margin," "piloerection," "emaciation," "gait disturbance" and "coma" (Agricultural Chemical Registration Data (1984)). These effects were observed at dosing levels within the guidance value ranges for Category 2.
9 Specific target organ toxicity - Repeated exposure Category 1 (pancreas) Danger H372: Cause damage to organs through prolonged or repeated exposure (pancreas) 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 ...
Based on the evidence from animal studies (Agricultural Chemical Registration Data (1984)): "atrophic changes of pancreatic exocrine cells" observed at dosing levels within the guidance value ranges for Category 1.
10 Aspiration hazard Classification not possible - - - - No data available

ENVIRONMENTAL HAZARDS
Hazard class Classification Symbol Signal word Hazard statement Precautionary statement Rationale for the classification
11 Hazardous to the aquatic environment (Acute) Category 1 Warning H400: Very toxic to aquatic life P273: Avoid release to the environment.
P391: Collect spillage.
P501: Dispose of contents/container to ...
It was classified into Category 1 from 96 hours LC50=0.89mg/L of the fish (Carp) (Agricultural Chemical Registration Data, 2005).
11 Hazardous to the aquatic environment (Long-term) Category 1 Warning H410: Very toxic to aquatic life with long lasting effects P273: Avoid release to the environment.
P391: Collect spillage.
P501: Dispose of contents/container to ...
Although acute toxicity is Category 1 and bio-accumulation is low (log Kow=3.69(PHYSPROP Database, 2005)), since there was no rapidly degrading (BIOWIN), it was classified into Category 1.
