PHYSICAL HAZARDS
Hazard class Classification Symbol Signal word Hazard statement Precautionary statement Rationale for the classification
1 Explosives Classification not possible - - - - Although the substance is containing chemical group (O-halogen) associated with explosive properties. Since no test results are available, classification is not possible.
2 Flammable gases (including chemically unstable gases) Not applicable - - - - Solid at room temperature (Merck (14th, 2006)).
3 Aerosols Not applicable - - - - Not aerosol products.
4 Oxidizing gases Not applicable - - - - Solid at room temperature (Merck (14th, 2006)).
5 Gases under pressure Not applicable - - - - Solid at room temperature (Merck (14th, 2006)).
6 Flammable liquids Not applicable - - - - Solid at room temperature (Merck (14th, 2006)).
7 Flammable solids Classification not possible - - - - No data available.
8 Self-reactive substances and mixtures Classification not possible - - - - Although the substance is containing chemical group (O-halogen) associated with explosive properties, no data is available.
9 Pyrophoric liquids Not applicable - - - - Solid at room temperature (Merck (14th, 2006)).
10 Pyrophoric solids Classification not possible - - - - No data available.
11 Self-heating substances and mixtures Classification not possible - - - - No data available.
12 Substances and mixtures which, in contact with water, emit flammable gases Not classified - - - - Although the substance contains a metal (K), its water solubility is 9.22 g/100 g (Lide (90th, 2009)) and it is considered that the substance doesn't react strongly with water, it is classified as "Not classified".
13 Oxidizing liquids Not applicable - - - - Solid at room temperature (Merck (14th, 2006)).
14 Oxidizing solids Classification not possible - - - - Although the substance is an inorganic compound containing iodine and oxygen, no data is available
15 Organic peroxides Not applicable - - - - Inorganic compound
16 Corrosive to metals Classification not possible - - - - Test methods applicable to solid substances are not available.

HEALTH HAZARDS

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 ...
Two LD50 values for mice of 531 and 1177 mg/kg bw were reported (JECFA FAO NMRS 40A, B, C (1966)), and both of them were equivalent to Category 4. Therefore, the substance was classified as Category 4.
1 Acute toxicity (Dermal) Classification not possible - - - - No data available.
1 Acute toxicity (Inhalation: Gases) Not applicable - - - - Solid at room temperature (Merck (14th, 2006))
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 Classification not possible - - - - No data available.
3 Serious eye damage/eye irritation Classification not possible - - - - No data available.
4 Respiratory sensitization Classification not possible - - - - No data available.
4 Skin sensitization Classification not possible - - - - No data were available. As relevant notes, iodine and its compounds were classified as "Group 2 for skin sensitizer" by Japan Society for Occupational Health, but all substances in this compound group were not identified (Recommendations of Occupational Exposure Limits (2010)).
5 Germ cell mutagenicity Classification not possible - - - - No data available.
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 - - - - No data available.
9 Specific target organ toxicity - Repeated exposure Classification not possible - - - - In the 100-day drinking study in mice, the effects on thyroid weights, follicular cells and follicular lumens were reported in the dose range of 0.05 - 0.6 mg/kg/day (dose level within the guidance values of Category 1) (CICAD 72 (2009)). However, the details were unknown due to no description for the number of animals used, the degree of each effect, etc. In addition, no data were available for other routes. Therefore, the classification was not possible.
10 Aspiration hazard Classification not possible - - - - No data available.
