Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

First-aid measures

If inhaled:

After inhalation of decomposition products: Keep patient calm, remove to fresh air, seek medical attention.

On skin contact:

Wash thoroughly with soap and water.

On contact with eyes:

Wash affected eyes for at least 15 minutes under running water with eyelids held open.

On ingestion:

Rinse mouth immediately and then drink plenty of water, seek medical attention.

Fire-fighting measures

Suitable extinguishing media:

water, carbon dioxide, foam

Specific hazards:

ammonia, carbon dioxide

The substances/groups of substances mentioned can be released in case of fire.

Further information:

Product itself is non-combustible; fire extinguishing method of surrounding areas must be considered.

Accidental release measures

Personal precautions:

Breathing protection required.

Methods for cleaning up or taking up:

For residues: Dampen, pick up mechanically and dispose of.

Handling and storage


No special measures necessary provided product is used correctly. Avoid dust formation. Ensure suitable air extract/ventilation on process machinery and transportation equipment. Ensure thorough ventilation of stores and work areas. The temperatures which must be avoided are to be considered. Sealed containers should be protected against heat as this results in pressure build-up. Handle in accordance with good industrial hygiene and safety practice.


Segregate from nitrites and alkaline substances. Segregate from strong acids. Segregate from strong bases.

Do not store with: sodium nitrate

Further information on storage conditions: Keep container tightly closed and dry. Keep only in the original container in a cool, well-ventilated place. Keep at temperature not exceeding 30 °C.

Protect from temperatures above: 30 °C

Changes in the properties of the product may occur if substance/product is stored above indicated temperature for extended periods of time.

Exposure controls / personal protection

Components with workplace control parameters

1066-33-7: ammonium hydrogencarbonate


Personal protective equipment

Respiratory protection:

Breathing protection if gases/vapours are formed. Gas filter for gases/vapours of inorganic compounds (e.g. EN 14387 Type B) Gas filter for gases/vapours of alkaline compounds such as ammonia, amines (e.g. EN 14387 Type K). Breathing protection if dusts are formed. Combination filter for gases/vapours of organic, inorganic, acid inorganic, alkaline compounds and toxic particles (e. g. EN 14387 Type ABEK-P3) Suitable respiratory protection for higher concentrations or long-term effect: Self-contained breathing apparatus.

Hand protection:

Suitable chemical resistant safety gloves (EN 374) also with prolonged, direct contact (Recommended: Protective index 6, corresponding > 480 minutes of permeation time according to EN 374): E.g. nitrile rubber (0.4 mm), chloroprene rubber (0.5 mm), butyl rubber (0.7 mm) and other

Supplementary note: The specifications are based on tests, literature data and information of glove manufacturers or are derived from similar substances by analogy. Due to many conditions (e.g. temperature) it must be considered, that the practical usage of a chemical-protective glove in practice may be much shorter than the permeation time determined through testing.

Manufacturer's directions for use should be observed because of great diversity of types.

Eye protection:

Safety glasses with side-shields (frame goggles) (e.g. EN 166)

Body protection:

Body protection must be chosen based on level of activity and exposure.

General safety and hygiene measures:

Do not breathe dust. At the end of the shift the skin should be cleaned and skin-care agents applied.

Stability and reactivity

Thermal decomposition:       > 30 °C

To avoid thermal decomposition, do not overheat.

Substances to avoid:

nitrites, nitrates, strong bases, strong acids

Hazardous reactions:

Exothermic reaction. Reacts with nitrates. Reacts with nitrites. Reacts with strong alkalies.

Hazardous decomposition products:

ammonia, carbon dioxide

Disposal considerations

Test for use in agriculture.
