HEALTH HAZARDS

P405: Store locked up.
P501: Dispose of contents/container to ... 		Based on the testing data of rat LD50 (oral route) of 0.117mmol/kg (equivalent to 5.733 mg/kg NaCN).
1 Acute toxicity （Dermal） Category 1 Danger H310: Fatal in contact with skin P302+P350: IF ON SKIN: Gently wash with plenty of soap and water.
P262: Do not get in eyes, on skin, or on clothing.
P264: Wash ... thoroughly after handling.
P270: Do not eat, drink or smoke when using this product.

P310: Immediately call a POISON CENTER or doctor/physician.
P322: Specific treatment （see ... on this label）.
P361: Remove/Take off immediately all contaminated clothing.
P363: Wash contaminated clothing before reuse.
P405: Store locked up.
P501: Dispose of contents/container to ... 		Based on the testing data of rabbit LD50 (dermal route) of 14.602 mg/kg (CICAD 61, 2004).
1 Acute toxicity （Inhalation: Gases） Not applicable - - - - Due to the fact that the substance is "solid" according to the GHS definition 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 - - - - No data available
2 Skin corrosion/irritation Category 3 - Warning H316: Causes mild skin irritation P332+P313: If skin irritation occurs: Get medical advice/attention. Based on the following description found in CICAD (2004): "Cyanide is slightly irritating to the skin and eye", although no data is available for sodium cyanide. Although the present substance is a salt of a weak acid and a strong base and the pH of its aqueous solution is expected to exceed 11.5, no description specifying the pH could be found, so classification by pH was not conducted.
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. 		Based on the following description found among the data on cyanide in CICAD (2004): "conjunctival hyperaemia with mild chemosis, lacrimation, photophobia, and tingling sensation", although the substance should be placed in Category 2A from the viewpoint of safety. Although the present substance is a salt of a weak acid and a strong base and the pH of its aqueous solution is expected to exceed 11.5, no description specifying the pH could be found, so classification by pH was not conducted.
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 - - - - Due to the lack of in vivo data and the presence of only one negative data from in vitro reverse mutation test, the substance could not be classified, following the guideline.
6 Carcinogenicity Classification not possible - - - - No data available
7 Reproductive toxicity Category 2 Warning H361: Suspected of damaging fertility or the unborn child P308+P313: IF exposed or concerned: Get medical advice/attention.
P201: Obtain special instructions before use.
P202: Do not handle until all safety precautions have been read and understood.
P281: Use personal protective equipment as required.
P405: Store locked up.
P501: Dispose of contents/container to ... 		Based on the evidence of malformation of the foetuses in Golden Syrian hamster teratogenicity tests, described in CICAD 61 (2004), and the absence of description of the effects on parent animals.
8 Specific target organ toxicity - Single exposure Classification not possible - - - - No data available
9 Specific target organ toxicity - Repeated exposure Category 1 (central nervous system, testis, kidney, adrenal gland, spleen) Danger H372: Cause damage to organs through prolonged or repeated exposure (central nervous system, testis, kidney, adrenal gland, spleen) 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 human evidence including "headache, debility, dysgeusia, dysosmia, dizziness, sensitive pharynx, vomiting, exertional dyspnea, watery eyes and anterior chest pain" (CICAD 61 (2004)) and the evidence from animal studies including "reduced sperm mobility, weight loss of the epididymal head" and "nephropathy, adrenal hypertrophy, necrosis and fibrosis in the pancreas, testicular germ cell degeneration" (CICAD 61 (2004). The effects on experimental animals were observed at dosing levels within the guidance value ranges for Category 1.
10 Aspiration hazard Classification not possible - - - - No data available

P501: Dispose of contents/container to ... 		It was classified into Category 1 from 96 hours LC50=0.05-0.075mg/L of the fish (Rainbow Trout) (IUCLID, 2000).
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 ... 		Since acute toxicity was Category 1 and an underwater action and bio-accumulation were unknown, it was classified into Category 1.
