12 Substances and mixtures which, in contact with water, emit flammable gases Not classified - - - - Although it contains a metalloid (P), its water solubility is 30 g/100 g (Lide (90th, 2009)), and it is considered that the substance doesn't react strongly with water.
13 Oxidizing liquids Not applicable - - - - Solid (GHS definition)
14 Oxidizing solids Not classified - - - - Although it is an inorganic compound containing oxygen, it is reported that it has no oxidizing properties (IUCLID (2000)), therefore it was classified as "Not classified".
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 ...
Based on the rat LD50 values of 1500 mg/kg and 1720 mg/kg (female) (IUCLID (2000)), the substance was classified as Category 4.
1 Acute toxicity (Dermal) Not classified - - - - Based on the rat LD50 value of > 5000 mg/kg (RTECS (2008), original literature: Federal Register. (U.S. Government Printing Office, Supt. Of Documents, Washington, DC 20402) V71, 36731 (2006)), the substance was classified as "Not classified".
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 - - - - Although the rat LC50 value of > 2.06 mg/L/4hrs (RTECS (2008), original literature: Federal Register. (U.S. Government Printing Office, Supt. Of Documents, Washington, DC 20402) V71, 36731, (2006)) was documented, this value did not provide a basis for classification, the substance was classified as "Classification not possible".
2 Skin corrosion/irritation Category 1 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.
P260: Do not breathe dust/fume/gas/mist/vapours/spray.
P264: Wash ... thoroughly after handling.
P280: Wear protective gloves/protective clothing/eye protection/face protection.
P310: Immediately call a POISON CENTER or doctor/physician.
P321: Specific treatment (see ... on this label).
P363: Wash contaminated clothing before reuse.
P405: Store locked up.
P501: Dispose of contents/container to ...
The substance was classified as Category 1 based on the result of "corrosive" in the rabbit test (OECD TG 404, GLP-compliant) (IUCLID (2000)). The substance was classified as "C; R35" in the EU classification (EU-Annex I (Access on May 2010)).
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.
The substance was classified as Category 1 based on the preexisting classification for skin corrosion/irritation.
4 Respiratory sensitization Classification not possible - - - - No data available.
4 Skin sensitization Classification not possible - - - - Insufficient data were available. "Not sensitizing" was reported for workers who treat the substance routinely, but the classification was not possible because no details were provided (IUCLID (2000)).
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 - - - - No data available.
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) Not classified - - - - Classified as "Not classified" from its 96h-LC50 = 6980 - 9784 mg/L for fish (Brachydanio rerio) (IUCLID, 2000).
11 Hazardous to the aquatic environment (Long-term) Not classified - - - - Classified as "Not classified" since it is not non-water soluble (water solubility: 13410 mg/L (PHYSPROP Database, 2011)) and its acute toxicity is "Not classified".
12 Hazardous to the ozone layer Classification not possible - - - - This substance is not listed in Annexes to the Montreal Protocol.
