In DFGOT vol.15 (2001), the zinc chromate compound including this product is set to "Sh (risk of skin sensitization)" based on the report of the contact nature dermatitis to the worker dealing with zinc chromate. Furthermore, chromium and chromium compound are classified into "the 1st group (substance which has sensitizing clearly to human)" in Japan Society for Occupational Health. This product thought that it had skin sensitization, and was set to Category 1.
5 Germ cell mutagenicity Classification not possible - - - - No data. In addition, although this product is the insoluble hexavalent chromium compounds, the mutagenicity knowledge in in vivo is indicated about many flood solubility hexavalent chromium compounds (NTP RoC (11th, 2005), IARC49 (1990), EU-RAR (2005)). Refer to potassium dichromate (ID 262, Chemical Abstracts Service:7778-50-9).
6 Carcinogenicity Category 1A Danger H350: May cause cancer 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.

As hexavalent chromium compounds, since it was was classified K (Chromium hexavalent (VI) compounds) in NTP (2005), group 1 (Chromium(VI)) in IARC (1990), and A (Chromium(VI), Inhalation route) in EPA (1986), respectively. So it was classified into Category 1A.
7 Reproductive toxicity Classification not possible - - - - There is no data. In addition, also refer to potassium dichromate (ID 262, CAS: 7778-50-9) as reproductive toxicity of hexavalent chromium compounds.
8 Specific target organ toxicity - Single exposure Category 1 (kidney, digestive system) Danger H370: Causes damage to organs (kidney, digestive system) P307+P311: IF exposed: Call a POISON CENTER or doctor/physician.

Since although there is no data about this product, there was description of vomiting, diarrhea, a spasm, a hemorrhagic nephritis, etc., when oral or percutaneous absorption is carried out as acute toxicities of the hexavalent chromium compound (DFGOT vol.3 (1992), DHP (13th, 2002)), it was considered as Category 1 (the kidney, alimentary system).
9 Specific target organ toxicity - Repeated exposure Category 1 (kidney, respiratory system) Danger H372: Cause damage to organs through prolonged or repeated exposure (kidney, respiratory system) 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 ...
Although there is no data of this product, because of descriptions of effects on a kidney, nasal septum perforation, ulcers, etc. as chronic toxicity of hexavalent chromium compounds (ACGIH (7th, 2001), IRIS (1998), DHP (13th, 2002)), it was classified into Category 1 (kidney, respiratory system).
