First-aid measures
Description of first aid measures
Remove contaminated clothing. First aid personnel should pay attention to their own safety.
If inhaled:
Keep patient calm, remove to fresh air, seek medical attention. If breathing difficulties develop, aid in breathing and seek immediate medical attention.
On skin contact:
Immediately wash thoroughly with plenty of water, apply sterile dressings, consult a skin specialist.
On contact with eyes:
In case of contact with the eyes, rinse immediately for at least 15 minutes with plenty of water. Immediate medical attention required.
On ingestion:
Immediately rinse mouth and then drink plenty of water, do not induce vomiting, seek medical attention.
Most important symptoms and effects, both acute and delayed
Symptoms: irritates the eyes and respiratory tract, skin corrosion
Indication of any immediate medical attention and special treatment needed
Treatment: Treat symptomatically.
Fire-fighting measures
Extinguishing media
Suitable extinguishing media:
Dry sand, dry soda ash, dry powder
Unsuitable extinguishing media for safety reasons:
water, foam, carbon dioxide, chlorinated hydrocarbons
Special hazards arising from the substance or mixture
Dust explosion hazard. Contact with water releases highly flammable and/or corrosive gases/vapours.
Advice for fire-fighters
Special protective equipment:
Wear self-contained breathing apparatus and chemical-protective clothing.
Further information:
Collect contaminated extinguishing water separately, do not allow to reach sewage or effluent systems. Dispose of fire debris and contaminated extinguishing water in accordance with official regulations. Sealed containers should be protected against heat as this results in pressure build-up. Keep people away and stay on the upwind side.
Accidental release measures
Personal precautions, protective equipment and emergency procedures
Avoid contact with the skin, eyes and clothing. Use breathing apparatus if exposed to vapours/dust/aerosol.
Environmental precautions
Discharge into the environment must be avoided.
Methods and material for containment and cleaning up
For small amounts: Sweep/shovel up. Correctly dispose of recovered product immediately.
For large amounts: Sweep/shovel up. Correctly dispose of recovered product immediately.
Handling and storage
Precautions for safe handling
Ensure thorough ventilation of stores and work areas. Breathing must be protected when large quantities are decanted without local exhaust ventilation. Protect against moisture. Protect from air. Protect from direct sunlight. Avoid dust formation.
Protection against fire and explosion:
Take precautionary measures against static discharges. Sources of ignition should be kept well clear. Fire extinguishers should be kept handy. Avoid dust formation.
Dust explosion class: Dust explosion class 3 (Kst-value >300 bar m s-1).
Conditions for safe storage, including any incompatibilities
Segregate from acids and acid forming substances.
Suitable materials for containers: Stove-lacquer RDL 16
Further information on storage conditions: Keep container tightly closed in a cool, well-ventilated place. Keep under nitrogen.
Storage stability:
Storage temperature: < 35 °C

Exposure controls / personal protection
Exposure controls
Personal protective equipment
Respiratory protection:
Breathing protection if breathable aerosols/dust are formed. 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):
butyl rubber (butyl) - 0.7 mm coating thickness
nitrile rubber (NBR) - 0.4 mm coating thickness
fluoroelastomer (FKM) - 0.7 mm coating thickness
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:
Tightly fitting safety goggles (cage goggles) (e.g. EN 166) and face shield.
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)., Protective clothing should be flame resistant.
General safety and hygiene measures
Avoid contact with the skin, eyes and clothing. Do not breathe dust.
Stability and reactivity
Reactivity
Strong exothermic reaction with acids.
Chemical stability
The product is stable under inert gas.
Possibility of hazardous reactions
Exothermic reaction. Reacts with water and acids. Reacts with substances which contain active hydrogen. Self heating possible in the presence of air. Accumulation of fine dust may entail the risk of a dust explosion in the presence of air.
Conditions to avoid
Avoid all sources of ignition: heat, sparks, open flame. Avoid electro-static discharge. Avoid humidity. Avoid dust formation. Avoid contact with air. Avoid moisture.
Incompatible materials
Substances to avoid:
carbon dioxide, halogens, water, alcohols, acids, halogenated hydrocarbons, oxidizing agents, halogenated compounds
Hazardous decomposition products
Hazardous decomposition products:
potassium hydroxide, 2-methylpropan-2-ol, carbon monoxide, carbon dioxide
Disposal considerations
Waste treatment methods
Incinerate in suitable incineration plant, observing local authority regulations.
Contaminated packaging:
Contaminated packaging should be emptied as far as possible; then it can be passed on for recycling after being thoroughly cleaned.
