First-aid measures


In some cases medical attention necessary (see below).                                   


Remove from source of exposure to dusts.

Obtain medical attention if ill effects occur.


Do not induce vomiting.

Rinse mouth and then give water or milk to drink.

Obtain medical attention if more than a small quantity has been swallowed.

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

Note to physician

Inhalation of fire and thermal decomposition gases, containing phosphorous and sulphur oxides, can cause irritation and corrosive effects on the respiratory system.

Some lung effects may be delayed.                                                                                                                                                                                                                                                                  


Fire-fighting measures

Suitable extinguishing media

If fertilizer is not directly involved in the Fire

Use the best means available to extinguish the Fire.

If fertilizer is involved in the Fire

Use plenty of water.

Extinguishing media not to be used

Do not use chemical extinguishers or foams or attempt to smother the fire with steam or sand.

Specific hazards

Non specified

Hazardous thermal decomposition and combustion products

At very high temperature ( > 1000ºC) decomposes to give toxic gases containing phosphorous and sulphur oxides

Special fire fighting procedures

Open doors and windows of the store to give maximum ventilation.

Avoid breathing the fumes (toxic). Stand up-wind of the Fire.

Prevent any contamination of fertilizer by oils or other combustible materials.

Special protective equipment for fire-fighters

Use a self-contained breathing apparatus if fumes are being entered.

Accidental release measures

Personal precautions

Avoid walking through spilled product and exposure to dust.

Environmental precautions

Take care to avoid the contamination of watercourses and drains and inform the appropriate authority in case of accidental contamination of watercourses.

Methods for cleaning up

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.


Material free from contamination can be used for its original purpose.

Handling and storage


Avoid excessive generation of dust.

Avoid contamination by combustible (e.g. diesel oil, grease, etc.) and/or other incompatible materials.

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.

Carefully clean all equipment prior to maintenance and repair.


Store in compliance with national and local regulations

Locate away from the sources of heat or fire.

Keep away from combustible materials and substances mentioned under Section10.

On farm, ensure that the fertilizer is not stored near hay, straw, grain, diesel oil, etc.

When stored loose, take particular care to avoid mixing with other fertilizers.

Ensure high standard of housekeeping in the storage area.

Do not permit smoking and the use of naked lights in the storage areas.

Restrict stack size (according to local regulations) and keep at least 1m distance around the stacks of bagged products.

Any building used for the storage should be dry and well ventilated.

Exposure controls / personal protection

Exposure limits values

No specific official EU limit. General non-hazardous dust exposure limit: 10 mg/m3.

ACGIH recommended value for nuisance dust for inhalable particulates: TLV/TWA : 10mg/m3.

Company input or where National Limits are specified.

Engineering measures

Avoid high dust concentration and provide ventilation where necessary.

Hygienic measures

When handling the product do not eat, drink or smoke. Wash hands after handling and before eating, smoking and using the lavatory and at the end of the working period.

Personal protection

Respiratory system

If ventilation is inadequate, use suitable dust mask or respirator if dust concentration with an appropriate filter (EN 143, 149, filters P2, P3).

Skin and body

Working clothes.


Wear suitable gloves (e.g. plastic, rubber or leather) when handling the product over long periods.


Safety glasses with side shields (EN 166).

Environmental exposure controls

See section accidental release measures

Advice on personal protection is applicable for high exposure levels.

Select proper personal protection based on a risk.

Stability and reactivity


The product is stable under normal conditions of storage, handling and use.

Conditions to avoid

Unnecessary exposure to the atmosphere.

Strong heat (decomposes).

Contamination by incompatible materials.

Closeness to sources of heat or fire.

Heating under confinement.

Welding or hot work on equipment or plant which may have contained fertilizer without first washing thoroughly to remove all fertilizer.

Materials to avoid

Alkalies, strong acids, copper and its alloys.

Hazardous decomposition products

For fire situation: see Section fire fighting measures

Ammonia is released upon reaction with strong bases or when heated.

See also Section Hazards Identification and Physical and chemical properties

Disposal considerations

Methods of disposal

Depending on degree and nature of contamination dispose of by use as fertilizer on farm, as raw material for liquid fertilizer, or to an authorised waste facility.

Do not empty into drains; dispose of this material and its container in a safe way and in accordance with all applicable local and national regulations.

Chapters 06 03 and 06 10 of the list of wastes (Commission decision 2000/532/EC )

Package waste disposal

Empty the bag by shaking to remove as much as possible of its contents.  If approved by local authorities, empty bags may be disposed of as non-hazardous material or returned for recycling.

Note: see section Handling and storage for safe handling and storage
