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.
2.2 classification
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.
Skin Contact
Prolonged contact may cause some irritation.
Eye Contact
May cause irritation following contact.
Ingestion
- Small quantities are unlikely to cause toxic effect.
- Large quantities give rise to gastro-intestinal disorders.
Inhalation
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.
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.
3.2 Environment
Ammonium sulphate is a nitrogen fertilizer. Heavy spillage may cause adverse environmental impact such as eutrophication in confined surface waters. (See Section 12.)
3.3 Other
Fire, heating and detonation
- 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.
4. FIRST-AID MEASURES
4.1 Product
Skin Contact
Wash the affected area with soap and water.
Eye Contact
- Flush/irrigate eyes with copious amounts of water for at least 10 minutes.
- Obtain medical attention if eye irritation persists.
Ingestion
- 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.
Inhalation
- Remove from source of exposure to dusts.
- Obtain medical advice if ill effects occur.
4.2 Fire and decomposition products
Skin Contact
- Wash areas in contact with molten material copiously with cold water.
- Obtain medical attention.
Inhalation
- 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
attention.
5. FIRE-FIGHTING MEASURES
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
- 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.
ACCIDENTAL RELEASE MEASURES
- 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.
7. HANDLING AND STORAGE
7.1 Handling
- 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.
7.2 Storage
- 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. EXPOSURE CONTROL / PERSONAL PROTECTION
8.1 Occupational exposure limits
- No specific official limit.
- ACGIH recommended value (1995-96) for inhalable particulate:
- TLV/TWA : 10mg/m3
8.2 Precautionary and engineering measures
Avoid high dust concentration and provide ventilation where necessary.
8.3 Personal Protection
- 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.
9. PHYSICAL AND CHEMICAL PROPERTIES
| Appearance | White/grey crystals |
| Odour | Odourless |
| pH water solution (conc. 10%) | 4-6 |
| Melting point | Decomposes at 235°C |
| Bulk density | 1000-1100kg/m3 |
| Solubility in water | 760g/l at 20°C |
10. STABILITY AND REACTIVITY
10.1 Stability
Stable under normal conditions of storage, handling and use.
10.2 Conditions 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.
10.3 Materials to avoid
Alkalies, strong acids, copper and its alloys.
10.4 Hazardous reactions/decomposition products
- Ammonia is released upon reaction with bases.
- (See also Section 3.3.)
11. TOXICOLOGICAL INFORMATION
11.1 General
See Section 3.1.
11.2 Toxicity Data
LD50 (oral, rat) > 2000mg/kg
12. ECOLOGICAL INFORMATION
12.1 Mobility
Soluble in water. Predicted to have high mobility in soil.
12.2 Persistence/Degradability
The product is substantially bio-degradable in water.
12.3 Bio-accumulation
Low potential.
12.4 Ecotoxicity
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
13.1 General
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
15.2
76/116/EEC (Law relating to fertilizers)
