First-aid measures

1. Description of first aid measures
Immediately remove contaminated clothing.

If inhaled:
If difficulties occur after dust has been inhaled, remove to fresh air and 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 and then drink plenty of water.


2. Most important symptoms and effects, both acute and delayed
Symptoms: The most important known symptoms and effects are described in the labelling. Further important symptoms and effects are so far not known.


3. Indication of any immediate medical attention and special treatment needed
Treatment: Treat according to symptoms (decontamination, vital functions), no known specific antidote.

Fire-fighting measures

1. Extinguishing media
Suitable extinguishing media:
Water in copious quantities

Unsuitable extinguishing media for safety reasons:
foam, dry powder, carbon dioxide

Additional information:
Soak with large amounts of water whenever possible together with wetting agents.

2. Special hazards arising from the substance or mixture
carbon oxides, nitrous gases, cobalt oxides, toxic gases/vapours
Once ignited, this product has the ability to continue to burn/decompose in the absence of air or oxygen.

3. Advice for fire-fighters
Special protective equipment:
Wear a self-contained breathing apparatus.

Further information:
The degree of risk is governed by the burning substance and the fire conditions. Contaminated extinguishing water must be disposed of in accordance with official regulations. Cool endangered containers with water-spray.

Accidental release measures

1. Personal precautions, protective equipment and emergency procedures
Avoid dust formation. Use personal protective clothing.

2. Environmental precautions
Contain contaminated water/firefighting water. Do not discharge into drains/surface waters/groundwater.

3. Methods and material for containment and cleaning up
For small amounts: Pick up with suitable appliance and dispose of.
For large amounts: Pick up with suitable appliance and dispose of.
Avoid raising dust. Do not empty into drains.

Handling and storage

1. Precautions for safe handling
Breathing must be protected when large quantities are decanted without local exhaust ventilation. Avoid contact with the skin, eyes and clothing. Avoid inhalation of dusts. Ensure adequate ventilation.

Protection against fire and explosion:
Avoid dust formation. Avoid whirling up the material/product because of the danger of dust explosion. Avoid all sources of ignition: heat, sparks, open flame. Take precautionary measures against static discharges.

Dust explosion class: Dust explosion class 2 (Kst-value 200 up to 300 bar m s-1).

2. Conditions for safe storage, including any incompatibilities
Seggregate from chemicals which may react with water, because in case of fire water will be used.
Further information on storage conditions: The undiluted dry powder must under no circumstances be exposed to strong mechanical forces. Keep container tightly closed and dry; store in a cool place. Keep only in the original container.

Exposure controls / personal protection

1. Control parameters

Components with occupational exposure limits


71839-88-8: Sodium bis[2,4-dihydro-4-[(2-hydroxy-5-nitrophenyl)azo]-5-methyl-2-phenyl-3H-pyrazol-3-onato(2-)]cobaltate(1-)
85203-44-7: Amines, C12-18-alkyl, bis[2,4-dihydro-4-[(2-hydroxy-5-nitrophenyl)azo]-5-methyl-2-phenyl-3H-pyrazol-3-onato(2-)]cobaltate(1-)

8.2. Exposure controls
Personal protective equipment
Respiratory protection:
Suitable respiratory protection for lower concentrations or short-term effect: Particle filter with medium efficiency for solid and liquid particles (e.g. EN 143 or 149, Type P2 or FFP2)

Hand protection:
Chemical resistant protective gloves (EN 374)
Suitable materials 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), polyvinylchloride (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 depending on activity and possible exposure, e.g. apron, protecting boots, chemical-protection suit (according to EN 14605 in case of splashes or EN ISO 13982 in case of dust).

General safety and hygiene measures
Handle in accordance with good industrial hygiene and safety practice. Wearing of closed work clothing is required additionally to the stated personal protection equipment.

Stability and reactivity

1. Reactivity
No hazardous reactions if stored and handled as prescribed/indicated.


2. Chemical stability
The product is stable if stored and handled as prescribed/indicated.

3. Possibility of hazardous reactions
Dust explosion hazard. Once ignited, this product has the ability to continue to burn/decompose in the absence of air or oxygen.


4. Conditions to avoid
Avoid dust formation. Avoid deposition of dust. Avoid sources of ignition. Avoid electro-static discharge.

5. Incompatible materials

Substances to avoid:
strong oxidizing agents, strong bases, strong acids

6. Hazardous decomposition products

Hazardous decomposition products:
carbon oxides, nitrogen oxides, cobalt oxides, toxic gases/vapours

Disposal considerations

Waste treatment methods

Must be disposed of or incinerated in accordance with local regulations.


Contaminated packaging:
Uncontaminated packaging can be re-used.
Packs that cannot be cleaned should be disposed of in the same manner as the contents.
