Prevent product from entering drains and waterways.

6.3 Methods of Cleaning Up

Contain spillage, then cover / absorb spill with non-combustible absorbent material (vermiculite, sand, or similar), collect and place in suitable containers for disposal. Recover spilt fertiliser as soon as possible.

If in a warehouse and the product has not been contaminated or degraded, return it to the original stockpile. Otherwise, store in a separate bay or containers.

If in the open, and the product cannot be immediately recovered, take steps to protect the product from the elements and loss to waterways. Cover the spilt product with a water-proof tarpaulin, weighed down to prevent it being blown off by wind.

For disposal options, see Section 13.

In agricultural fields, spread any residual fertiliser out over as wide an area as possible. If left too thick, plant growth may be affected. Plants may die, and germination and emergence stifled for some time.

6.4 Reference to Other Sections

See Sections 8 and 13 for exposure controls and disposal.

7. Handling and Storage

Store in cool dry place. Isolate away from incompatible substances . Ensure containers /bags/bays are labeled adequately and are protected from physical damage and in a well- ventilated area. When stored in confined area, this product can give off an odour and lead to the depletion of oxygen within this space and other confined spaces. Do not allow product to come into contact with Water. If product is bagged, these bags should be stored undercover and away from direct sunlight. Use safe work practices. Avoid eye of skin contact and dust inhalation. Observe good personal hygiene, including washing hands before eating. Not suitable for Silo Storage

8. Exposure Controls / Personal Protection

8.1 Control Parameters

Exposure standards: No exposure standards have been entered for this product. Biological limits: No biological limit values have been entered for this product.

8.2 Exposure Controls

Engineering controls: Avoid inhalation.

PPE: The selection of Personal Protective Equipment (PPE) should be based on a Risk Assessment of the amount of dust likely to be generated, including the quantity of product being handled, the presence and amount of fines and dust; the task being performed, the work environment in which it is being undertaken, and the level of exposure. Normal work clothing may suffice during transfer operations in the field, e.g. when filling fertiliser boxes, and in bulk storage facilities where contact with the product is limited under well ventilated conditions and occupational exposure limits are not exceeded.

Eye / Face: Where eye contact may occur, wear safety glasses with side shields.
Hands: Cotton gloves, which can be washed or disposed of if heavily soiled, will suffice under most circumstances. Use impervious PVC or rubber gloves in high risk situations.
Body: Where skin contact may occur and for individuals with sensitive skin, wear ankle length and long sleeved clothing or overalls.
Respiratory: Wear a dust mask where exposure to dust is light. Where the dust nuisance is high and ventilation is inadequate, use a properly fitted particulate filter respirator, either full face-piece or half mask plus goggles, that meets Australian Standards AS/NZS 1715 and AS/NZS 1716 "Selection, use and maintenance of respiratory protective devices".

[Diagrams: Icons for safety glasses, gloves, and dust mask]

Wash dust from hands and exposed skin. In risk situations, locate an eyewash station nearby. Wash contaminated clothing and other protective equipment before storage or reuse. Ensure all PPE conforms to the relevant Australian Standards. Read the labels on the PPE.

12. Ecological Information

12.1 Toxicity

No information provided.

12.2 Persistence and Degradability

No information provided.

12.3 Bioaccumulative Potential

No information provided.

12.4 Other Adverse Effects

Avoid contamination of drains and waterways. Fertilisers, particularly those containing nitrogen and/or phosphorus, can stimulate weed and algal growth in static surface waters. Nitrogen fertilisers may contain or form nitrate which can contaminate surface and ground-water. High nitrate concentrations may render the water unsuitable for human and livestock consumption. This product can stimulate weed and algal growth if lost to static surface waterways. Algae affect water quality and taste.

13. Disposal Considerations

13.1 Waste Treatment Methods

Waste disposal: Ideally, the fertiliser should be used for its intended purpose. Beneficial reuse is the preferred disposal option. For fertiliser that is physically degraded but not contaminated in any way, this may necessitate using different application equipment and methods to apply it. If the fertiliser is contaminated with other fertilisers , soil, or other non-harmful substances, and it can be satisfactorily applied, use it for its nutrient value in pasture, crops or on a recreational area, e.g. lawns and parks. If contaminated with other materials , e.g. fuel, oil or chemicals The fertiliser waste must be disposed of in accordance with relevant local legislation . Contact the Waste Management Authority for advice. Legislation: Dispose of in accordance with relevant local legislation.
