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	-	-	-	-	Liquid (GHS definition)
3	Aerosols	Not applicable	-	-	-	-	Not aerosol products
4	Oxidizing gases	Not applicable	-	-	-	-	Liquid (GHS definition)
5	Gases under pressure	Not applicable	-	-	-	-	Liquid (GHS definition)
6	Flammable liquids	Not classified	-	-	-	-	Nonflammable (ICSC (J), 2001). However, this product is highly reactive, and since it may react with other substances to cause fire and explosions, caution is needed.
7	Flammable solids	Not applicable	-	-	-	-	Liquid (GHS definition)
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 classified	-	-	-	-	Nonflammable (ICSC (J), 2001). However, since this product is highly reactive, and it may react with other substances and cause fire and explosions, it needs attention.
10	Pyrophoric solids	Not applicable	-	-	-	-	Liquid (GHS definition)
11	Self-heating substances and mixtures	Not classified	-	-	-	-	Nonflammable (ICSC (J) 2001). However, the this product of reactive is high, and since it may react with other substances and fire and explosions may be caused, it need to be careful.
12	Substances and mixtures which, in contact with water, emit flammable gases	Not classified	-	-	-	-	Although it reacted violently with water and hydrochloric acids and sulfates were produced, all are nonflammability and were carried out the outside of Category.
13	Oxidizing liquids	Not classified	-	-	-	-	Not classified because of UNRTDG No. 1754, Class: 8, PG I (not Class: 5.1), though it is a strong oxidizing agent (ICSC(J), 2001; NFPA, 13th, 2002)
14	Oxidizing solids	Not applicable	-	-	-	-	Liquid (GHS definition)
15	Organic peroxides	Not applicable	-	-	-	-	Inorganic compound
16	Corrosive to metals	Category 1		Warning	H290: May be corrosive to metals	P234: Keep only in original container. P390: Absorb spillage to prevent material-damage. P406: Store in corrosive resistant/... container with a resistant inner liner.	UNRTDG is classified into 8 and I according to the UNRTDG No. (1754). Since NFPA (13th, 2002) had the description "perform transportation with a glass bottles", it was thought that corrosion behavior was strong and it was set as Category 1.

1	Acute toxicity （Inhalation: Vapours）	Category 1		Danger	H330: Fatal if inhaled	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. P260: Do not breathe dust/fume/gas/mist/vapours/spray. P271: Use only outdoors or in a well-ventilated area.

P501: Dispose of contents/container to ...	It was classified as Category 1 from the higher toxic value (LC50 (4h) = 0.0385mg/L).(This value is from rat LC50 (4h) = 4.779mg/L (= 1003ppm, RTECS (2000)), 0.0385mg/L (= 8ppm, IUCLID (2000), HSDB (2003))). In addition, the saturated concentration of this product is 1317ppm, and it is presumed that each inhalation experiments was conducted in the state of steam.
1	Acute toxicity （Inhalation: Dusts and mists）	Classification not possible	-	-	-	-	No data available
2	Skin corrosion/irritation	Category 1A-1C		Danger	H314: Causes severe skin burns and eye damage	P301+P330+P331: IF SWALLOWED: Rinse mouth. Do NOT induce vomiting. P303+P361+P353: IF ON SKIN （or hair）: Remove/Take off immediately all contaminated clothing. Rinse skin with water/shower. P305+P351+P338: IF IN EYES: Rinse cautiously with water for several minutes. Remove contact lenses, if present and easy to do. Continue rinsing. P304+P340: IF INHALED: Remove victim to fresh air and keep at rest in a position comfortable for breathing.

P501: Dispose of contents/container to ...	There is the description that there is caustic to human skin (HSDB and (2003), ICSC (J), (2001), SITTIG (4th, 2002)), and it was classified into "C;R35" in the European risk phrases. So it was set as category 1A-1C. [view] When further categorizing needs to be performed, it is desirable to be set as category 1A from a viewpoint of safety.
3	Serious eye damage/eye irritation	Category 1		Danger	H318: Causes serious eye damage	P305+P351+P338: IF IN EYES: Rinse cautiously with water for several minutes. Remove contact lenses, if present and easy to do. Continue rinsing. P280: Wear protective gloves/protective clothing/eye protection/face protection. P310: Immediately call a POISON CENTER or doctor/physician.	In addition to being skin corrosive substances (Category 1), strong corrosive to the human eye, the irreversible damage to eye (HSDB (2003), ICSC (J), (2001), SITTIG (4th, 2002)), it was classified into Category 1.

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. P405: Store locked up. P501: Dispose of contents/container to ...	It was considered as Category 2 (inhalation: respiratory systems).) based on the description that in Priority 2, pulmonary edemas is caused for humans by inhalation (ICSC (J), (2001)), moreover, the irritation/caustic to an airway are observed (SITTIG (4th, 2002), ICSC(J) (2001)).
9	Specific target organ toxicity - Repeated exposure	Category 2 (respiratory system)		Warning	H373: May cause damage to organs through prolonged or repeated exposure (respiratory system)	P260: Do not breathe dust/fume/gas/mist/vapours/spray. P314: Get medical advice/attention if you feel unwell. P501: Dispose of contents/container to ...	Because there were descriptions in Priority 2 that repeated exposure risks the human lungs (ICSC (J), (2001)) and starts bronchitis (SITTIG (4th, 2002)), it was classified into Category 2 (respiratory systems). In addition, it is supposed that teeth are affected and tooth acid corrosions are occured (ICSC (J), (2001)).

ENVIRONMENTAL HAZARDS

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	P273: Avoid release to the environment. P501: Dispose of contents/container to ...	It was classified into Category 3 from 24-hour EC50=32mg/L of Crustacea (Daphnia magna) (AQUIRE, 2003).
11	Hazardous to the aquatic environment （Long-term）	Not classified	-	-	-	-	Toxicity factor is considered pH decrease (it hydrolyzed and hydrochloric acid and aulfuric acid are generated), but toxic effect is eased by the buffer action in the environmental water.
