Based on the rat LD50 value of 854 mg/kg (RTECS (2007), original literature: Journal of the American Pharmaceutical Association, Scientific Edition. Volume 29,152 (1940)), the substance was classified as Category 4. [For health hazards, refer also to other thiocyanates.] |

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 ... |
No data were available for this substance, however, it was known that thiocyanate inhibited the uptake of iodine in the thyroid and showed thyroid toxicity (CICAD (J) 61 (2004), ATSDR (2006)). In addition, thiocyanate was the primary metabolite of cyanides and it was reported that occupational exposure to cyanides induced thyroid dysfunction and goiter (CICAD (J) 61 (2004), ATSDR (2006)). Based on the information, therefore, the classification was determined as Category 1 (thyroid). |
| 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） | Category 3 | - | - | H402: Harmful to aquatic life |

Classified into Category 3 from its 96h-LC50 = 52.5 mg/L for fish (Oncorhynchus mykiss) (ECETOC TR91, 2003). |
| 11 | Hazardous to the aquatic environment （Long-term） | Not classified | - | - | - | - | Classified as "Not classified" from 124d-NOEC (Reproduction) = 1.1 mg/L for fish (Pimephales promelas) though its acute toxicity is Category 3 and it is not rapidly degradable (ECETOC TR91, 2003). |
| 12 | Hazardous to the ozone layer | Classification not possible | - | - | - | - | This substance is not listed in Annexes to the Montreal Protocol. |
