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 Classification not possible - - - - Although ICSC (J)(1998) of sodium selenite (anhydride) has the description "it is a flammable under specific conditions", the conditions or examination data are not available. And data is insufficient, it cannot be classified.
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 - - - - Even if it contacts the normal temperature air, it does not ignite spontaneously. (Merck (13th, 2001) of sodium selenite (anhydride) indicates "It is stabilized in the air".)
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 - - - - Stable to water. (aqueous solubility values is acquired with sodium selenite (anhydride).)
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.

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. * Since the this product has little data, refer also to the classification result of sodium selenite (anhydride) (ID No.1063, Chemical Abstracts Service No.10102-18-8) for each item of the healthy hazards.
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 Classification not possible - - - - No data available
3 Serious eye damage/eye irritation Category 2A-2B Warning H319: Causes serious 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.
P280: Wear protective gloves/protective clothing/eye protection/face protection.
Although there was no data about this product, it irritaties to the eye as selenium compound in ACGIH-TLV(2004). Since there was no data used as the index of subdivision, it was classified into Category 2A-2B. [Indication] 2A is recommended based on the safety, when the Category needs to subdivide.
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 - - - - Classification not possible due to lack of data
6 Carcinogenicity Not classified - - - - As selenium compounds, it is categorized into D in IRIS (1993) and is categorized into Group 3 in IARC9 (1975). It was out of the Category.
7 Reproductive toxicity Classification not possible - - - - Although the data of a mouse is in RTECS (2004), it is inadequate contents for classification determination. And since data is insufficient, it cannot be classified.
8 Specific target organ toxicity - Single exposure Category 3 (Respiratory tract irritation) Warning H335: May cause respiratory irritation (respiratory tract irritation) 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.
P405: Store locked up.
P501: Dispose of contents/container to ...
No data available. NOTE: Classified into Category 3(Respiratory tract irritation). It is based on the evidence that selenium compounds are respiratory tract irritants (ACGIH-TLV (2004)).
9 Specific target organ toxicity - Repeated exposure Classification not possible - - - - Although there are three reports of repetitive exposure to a rat in RTECS (2004), the information about the toxic phenomena is not sufficient, and it cannot be classified due to insufficient data.
10 Aspiration hazard Classification not possible - - - - No data available

ENVIRONMENTAL HAZARDS
Hazard class Classification Symbol Signal word Hazard statement Precautionary statement Rationale for the classification
11 Hazardous to the aquatic environment (Acute) Category 1 Warning H400: Very toxic to aquatic life P273: Avoid release to the environment.
P391: Collect spillage.
P501: Dispose of contents/container to ...
It was classified into Category 1 from 72-hour EC50=80microg/L of algae (Scenedesmus) (AQUIRE, 2003).
11 Hazardous to the aquatic environment (Long-term) Category 1 Warning H410: Very toxic to aquatic life with long lasting effects P273: Avoid release to the environment.
P391: Collect spillage.
P501: Dispose of contents/container to ...
Classified into Category 1, since acute toxicity was Category 1, and it is a metallic compound, behavior in water and bioaccumulative potential are unknown.
