5 Gases under pressure Not applicable - - - - Solid (GHS definition)
6 Flammable liquids Not applicable - - - - Solid (GHS definition)
7 Flammable solids Not classified - - - - CHRIS-Chemical Hazards Response Information System (U. S.DOT/U.S.Coast Guard, 1999) has the statement that it is nonflammable (as CAS No.1303-32-8). It was classified as out of Category. However, Merck (13th, 2001) also has the description "it ignites at elevated temperatures."

HEALTH HAZARDS
Hazard class Classification Symbol Signal word Hazard statement Precautionary statement Rationale for the classification
1 Acute toxicity (Oral) Classification not possible - - - - Without data. [Note] The datum on the "health hazards" of this product is the same as ID 1093 (sulfidesi arsenic, As2S2, CAS 1303-32-8).
1 Acute toxicity (Dermal) Classification not possible - - - - No data available
1 Acute toxicity (Inhalation: Gases) Not applicable - - - - Solid (GHS definition)
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 Category 3 - Warning H316: Causes mild skin irritation P332+P313: If skin irritation occurs: Get medical advice/attention. The knowledge of this product was not acknowledged. But it was judged to have slight irritation, and it was set to category 3 from the description which indicates that an inorganic arsenic had irritation (DFGOT 21, 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.
Although there was no evidence of this product, due to the description that the arsenic compounds particulate irritates to the eye (DFGOT 21, 2005), it was classified into Category 2B.
4 Respiratory sensitization Classification not possible - - - - No data available
4 Skin sensitization Classification not possible - - - - It is not a deterministic conclusion (ATSDR, 2005; HSG, 1992) although there is no knowledge of the quality of a genuine article itself and skin sensitization may be shown to humans as an inorganic arsenic compound, in addition, it was presupposed that it cannot classify from the description in the humans of EHC 224 (2001) "development of the skin sensitization of inorganic arsenic is rare" since data is insufficient.
5 Germ cell mutagenicity Classification not possible - - - - Without data. In addition, arsenic and inorganic arsenic compound are classified into the germ-cell mutagenicity category 3A (equivalent for GHS Category 1B-2) in Germany DFG (MAK/BAT, 2005).
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.
P281: Use personal protective equipment as required.
P405: Store locked up.
P501: Dispose of contents/container to ...
Arsenic and arsenic compound are categorized into the human carcinogens in IARC Suppl.7 (1987), ACGHI-TLV (2004), and MAK/BAT (2004). So it was classified into Category 1A.
7 Reproductive toxicity Category 2 Warning H361: Suspected of damaging fertility or the unborn child 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.
P281: Use personal protective equipment as required.
P405: Store locked up.
P501: Dispose of contents/container to ...
Although the knowledge of this product was not observed, it was considered as Category 2 based on the description related to human of EHC 224 (2001) which is Priority 1 document, about arsenic and arsenic compound, "the effect on reproduction is suggested ", and knowledge of animals "fetus toxicity and teratogenicity in dose in which maternal toxicity is observed". In addition, there is the description that "the conclusion which is inorganic arsenic is not teratogen in humans is advocated " in Catalog of teratogenic agents (2004) equivalent to Priority 1.
8 Specific target organ toxicity - Single exposure Category 1 (digestive system, cardiovascular system, nervous system, kidney, liver, respiratory system) Danger H370: Causes damage to organs (digestive system, cardiovascular system, nervous system, kidney, liver, respiratory system) 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 ...
Although there was no information about this substance, the substance was classified as Category 1 (gastrointestinal system, cardio-vascular system, nervous system, kidneys, liver, respiratory system) based on the report that in the forms of the arsenic and inorganic arsenic compounds it causes "symptoms in the gastrointestinal organs, disorders in the functions of the cardio-vascular and nervous systems, myelosuppression, alteration in the blood system and nephropathy" in humans (EHC 224 (2001)), and based on a similar report in PIM (Poisons Information Monographs) G042 (WHO/IPCS, 1996). In addition, there is a report in ACGIH (7th, 2001) that it affects the liver, upper airways and lungs.
9 Specific target organ toxicity - Repeated exposure Category 1 (digestive system, nervous system, blood system, cardiovascular system, kidney, liver, skin, respiratory system) Danger H372: Cause damage to organs through prolonged or repeated exposure (digestive system, nervous system, blood system, cardiovascular system, kidney, liver, skin, 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 the knowledge of this product was not observed, based on the description in the humans about arsenic and inorganic arsenics compounds, "gastrointestinal disturbances, neuropathy, affect to blood systems, and disorders of cardiovascular systems, kidney and liver were observed in the long term administration of inorganic arsenic. Target organ are gastrointestinal,heart,brains and kidney. The skin, marrow and peripheral nerves were also affected." (EHC 224 (2001), and PIM(Poisons Information Monographs) G042 (WHO/IPCS, 1996)) and the description of effect on the upper respiratory tract and lungs (ACGIH (7th, 2001)), therefore it was classified into Category 1 (digestive tract, cardiovascular systems, nervous systems, kidney, liver, blood systems, skin, respiratory system)
