HEALTH HAZARDS

1 Acute toxicity (Oral) Not classified - - - - Based on a LD50 value of 5440 mg/kg bw for rats (IUCLID (2000)), the substance was classified into "Not classified".
1 Acute toxicity (Dermal) Classification not possible - - - - No data available.
1 Acute toxicity (Inhalation: Gases) Not applicable - - - - Solid at room temperature (Sax (11th, 2004))
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 2 Warning H315: Causes skin irritation P302+P352: IF ON SKIN: Wash with plenty of soap and water.
P332+P313: If skin irritation occurs: Get medical advice/attention.
P264: Wash ... thoroughly after handling.
P280: Wear protective gloves/protective clothing/eye protection/face protection.
P321: Specific treatment (see ... on this label).
P362: Take off contaminated clothing and wash before reuse.
Since there is a report that magnesium nitrate hexahydrate is a "severe irritant" for human skin (HSDB (2003)) and the damages are considered to be reversible due to lack of report of corrosive, the substance was classified into Category 2. As relevant information, there is a result of "mild irritating" in standard Draize test where 500 mg was applied to rabbits for 24-hour (RTECS (1998)).
3 Serious eye damage/eye irritation Category 2 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.
There is report that magnesium nitrate hexahydrate is a "severe irritant" for human eye (HSDB (2003)) and there is a result of "mild irritating" in standard Draize test in which 500 mg was applied to rabbits (IUCLID (2000)). Based on above information, magnesium nitrate is considered to cause reversible irritation based on the result of mild irritating in Draize test and the substance was classified into Category 2.
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 2 (blood) Warning H371: May cause damage to organs (blood) P309+P311: IF exposed or if you feel unwell: 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.
P405: Store locked up.
P501: Dispose of contents/container to ...
There are reports that magnesium nitrate is a methemoglobin-forming agent (HSDB (2003)) and that ingestion could cause effects on the blood and may result in formation of methaemoglobin (ICSC (2003)). Based on this information found in documents in List 2 and List 3, respectively, the substance was classified into Category 2 (blood system).
9 Specific target organ toxicity - Repeated exposure Classification not possible - - - - No data available. As relevant information, there is a report that methemoglobinemia was developed in humans following ingestion of potassium nitrate over a period of 12 days (HSDB (access on Jan. 2010)).
10 Aspiration hazard Classification not possible - - - - No data available.
