PHYSICAL HAZARDS
Hazard class Classification Symbol Signal word Hazard statement Precautionary statement Rationale for the classification
1 Explosives Not applicable - - - - There are no chemical groups associated with explosive properties present in the molecules.
2 Flammable gases （including chemically unstable gases） Not applicable - - - - Solid (GHS definition)
3 Aerosols Not applicable - - - - Not aerosol products
4 Oxidizing gases Not applicable - - - - Solid (GHS definition)
5 Gases under pressure Not applicable - - - - Solid (GHS definition)
6 Flammable liquids Not applicable - - - - Solid (GHS definition)
7 Flammable solids Not classified - - - - Nonflammable (ICSC (J), 1999). (However, since this product may react with other substances and burn, cautions are required.)
8 Self-reactive substances and mixtures Not applicable - - - - There are no chemical groups associated with explosive or self-reactive properties present in the molecule.
9 Pyrophoric liquids Not applicable - - - - Solid (GHS definition)
10 Pyrophoric solids Not classified - - - - Non-combustible (ICSC (J), 1999)
11 Self-heating substances and mixtures Not classified - - - - Not combustible (ICSC(J) (1999))
12 Substances and mixtures which, in contact with water, emit flammable gases Not classified - - - - UNRTDG is classified into 6.1 and III according to the U.N. number (1884) peculiar to a substance. Since 4.3 which indicates a water reaction inflammability chemistry article was not attached, it carried out the outside of Category. (Since a high fevers is emitted when the this product reacts with water and barium hydroxide is generated, extreme cares are required.)
13 Oxidizing liquids Not applicable - - - - Solid (GHS definition)
14 Oxidizing solids Classification not possible - - - - No data available
15 Organic peroxides Not applicable - - - - Inorganic compound
16 Corrosive to metals Classification not possible - - - - Test methods applicable to solid substances are not available.

2 Skin corrosion/irritation Category 3 - Warning H316: Causes mild skin irritation P332+P313: If skin irritation occurs: Get medical advice/attention. It was set as category 3 from the description that there is a stimulus, redness, and a pain to the human skin (ICSC(J), 1999; HSFS, 2002), and that it stimulates the skin as water-soluble barium compounds (ACGIH-TLV, 2005).
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. 		It was set as Category 2B from description that there are stimulus, redness and pain to the human eye (ICSC(J), 1999; HSFS, 2002), and the eye is stimulated as water-soluble barium compounds (ACGIH-TLV, 2005).
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 - - - - 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 Category 1 (digestive system, heart, muscle), Category 2 (nervous system), Category 3 (respiratory tract irritation) Danger
Warning 		H370: Causes damage to organs (digestive system, heart, muscle)
H371: May cause damage to organs (nervous system)
H335: May cause respiratory irritation (respiratory tract irritation) 		P307+P311: IF exposed: 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.
P321: Specific treatment （see ... on this label）.
P405: Store locked up.
P501: Dispose of contents/container to ...
P309+P311: IF exposed or if you feel unwell: Call a POISON CENTER or doctor/physician.
P304+P340: IF INHALED: Remove victim to fresh air and keep at rest in a position comfortable for breathing.
P403+P233: Store in a well-ventilated place. Keep container tightly closed.
P261: Avoid breathing dust/fume/gas/mist/vapours/spray.
P271: Use only outdoors or in a well-ventilated area.
P312: Call a POISON CENTER or doctor/physician if you feel unwell. 		It was considered as Category 1 (a digestive systems, the heart, muscles), Category 2 (nervous system), and Category 3 (respiratory irritant) based on the description that gastrointestinal irritation, muscle disorder (ACGIH-TLV, 2005), gastroenteritis, hypokalemia, high blood pressure, arrhythmia, and skeletal muscle paralysis (CICAD 33, 2001) are caused, and it stimulates the human respiratory tract, affects a nervous system, causes hypokalemia and may produce heart damages / muscle disorders as a water-soluble barium compounds (ICSC (J), 1999).
9 Specific target organ toxicity - Repeated exposure Category 1 (respiratory system) Danger H372: Cause damage to organs through prolonged or repeated exposure (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 ... 		It was classified into Category 1(respiratory systems) based on description of bronchitis (CICAD 33, 2001) and of stimulation to lungs in repeated exposure (HSFS, 2002).
