|Designation||EC Fertilizer, Ammonium Sulphate|
|Commonly used synonyms||-|
|EINECS Name||Ammonium Sulphate|
|Molecular formula||(NH4)2 SO4|
1.3 Emergency calls
|official Advisory Body||Telephone No.|
2. COMPOSITION/INFORMATION ON INGREDIENTS
2.1 Nature of ingredients and concentration
Essentially pure ammonium sulphate with a small amount of moisture, contains 21% ammoniacal nitrogen.
Not classed as hazardous material according to EEC Directive 67/548/EEC.
3. HAZARDS IDENTIFICATION
3.1 Human health
The product has low toxicity. However, the following points should be noted.
Prolonged contact may cause some irritation.
May cause irritation following contact.
High dust concentrations of air-borne material may cause irritation of the nose and upper
respiratory tract with symptoms such as sore throat and coughing.
- Small quantities are unlikely to cause toxic effect.
- Large quantities give rise to gastro-intestinal disorders.
Long term effects
No adverse effects are known
Fire and thermal decomposition products
Inhalation of decomposition gases can cause irritation and corrosive effects on the respiratory
system. Some lung effects may be delayed.
Ammonium sulphate is a nitrogen fertilizer. Heavy spillage may cause adverse environmental impact such as eutrophication in confined surface waters. (See Section 12.)
Fire, heating and detonation
4. FIRST-AID MEASURES
- It is not combustible and does not support combustion.
- Thermal decomposition products include sulphur oxides and ammonia.
- Combustion of ammonia could result in emission of toxic nitrogen oxide gases.
- Can produce thermally sensitive mixtures with potassium chlorate and potassium nitrate and can enhance the explosive properties of ammonium nitrate.
Wash the affected area with soap and water.
- Flush/irrigate eyes with copious amounts of water for at least 10 minutes.
- Obtain medical attention if eye irritation persists.
- Do not induce vomiting.
- Give water or milk to drink.
- Obtain medical attention if more than a small quantity has been swallowed or when relevant symptoms occur after swallowing.
4.2 Fire and decomposition products
- Remove from source of exposure to dusts.
- Obtain medical advice if ill effects occur.
- Wash areas in contact with molten material copiously with cold water.
- Obtain medical attention.
5. FIRE-FIGHTING MEASURES
- Remove from the source of exposure to fumes.
- Keep warm and at rest.
- Persons who have inhaled decomposition gases (e.g. in a Fire) should obtain immediate medical
5.1 If fertilizer is not directly involved in the Fire
Use the best means available to extinguish the Fire.
5.2 If fertilizer is involved in the Fire
ACCIDENTAL RELEASE MEASURES
- Call the Fire brigade.
- Avoid breathing any fumes (toxic). Stand up-wind of the Fire.
- Wear self-contained breathing apparatus if fumes are being entered.
- Use plenty of water.
- Open doors and windows of the store to give maximum ventilation.
- If water containing fertilizer enters any drains or watercourse, inform the local authorities immediately.
- See also Section 3.
7. HANDLING AND STORAGE
- Any spillage of fertilizer should be cleaned up promptly, swept up and placed in a clean labelled open container for safe disposal.
- Depending on the degree and nature of contamination, dispose of by use as a fertilizer on farm or to an authorised waste facility.
- Take care to avoid the contamination of watercourses and drains and inform the appropriate authority in case of accidental contamination of watercourses.
- Avoid excessive generation of dust.
- Avoid unnecessary exposure to the atmosphere to prevent moisture pick-up.
- When handling the product over long periods use appropriate personal protective equipment e.g. gloves.
8. EXPOSURE CONTROL / PERSONAL PROTECTION
- Locate away from the sources of heat or Fire.
- Keep away from combustible materials, any lime or basic materials and other incompatible substances. (See Section 10.3.)
- Ensure high standard of housekeeping in the storage area.
- Any building used for the storage should be dry and well ventilated.
8.1 Occupational exposure limits
8.2 Precautionary and engineering measures
- No specific official limit.
- ACGIH recommended value (1995-96) for inhalable particulate:
- TLV/TWA : 10mg/m3
Avoid high dust concentration and provide ventilation where necessary.
8.3 Personal Protection
9. PHYSICAL AND CHEMICAL PROPERTIES
- Wear suitable gloves when handling the product over long periods.
- Use suitable dust respirator if dust concentration is high.
- After handling product, wash hands and observe good hygiene practice.
|pH water solution (conc. 10%)||4-6|
|Melting point||Decomposes at 235°C|
|Solubility in water||760g/l at 20°C|
10. STABILITY AND REACTIVITY
Stable under normal conditions of storage, handling and use.
10.2 Conditions to avoid
10.3 Materials to avoid
- Contamination by incompatible materials.
- Welding or hot work to equipment and pipelines or plant which may have contained fertilizer without First washing thoroughly to remove all fertilizer.
Alkalies, strong acids, copper and its alloys.
10.4 Hazardous reactions/decomposition products
11. TOXICOLOGICAL INFORMATION
- Ammonia is released upon reaction with bases.
- (See also Section 3.3.)
See Section 3.1.
11.2 Toxicity Data
LD50 (oral, rat) > 2000mg/kg
12. ECOLOGICAL INFORMATION
Soluble in water. Predicted to have high mobility in soil.
The product is substantially bio-degradable in water.
Harmful to aquatic organisms. Increases in pH above 7.5 will lead to an increased load of non-ionised ammonia which is markedly more toxic to aquatic life.
13. DISPOSAL CONSIDERATIONS
Depending on degree and nature of contamination, dispose of by use as fertilizer by spreading or to an authorised waste facility.
14. TRANSPORT INFORMATION
14.1 UN Classification
Not classed ie considered non-hazardous material according to UN Orange Book and international
transport codes e.g. RID (rail), ADR (road) and IMDG (sea).
15. REGULATORY INFORMATION
15.1 EEC Directives
76/116/EEC (Law relating to fertilizers)
15.2 National laws
