Inhalation: Move to fresh air. Call a physician if symptoms develop or persist.
Skin contact: Wash skin with soap and water. Get medical attention if irritation develops and persists.
Eye contact: Rinse immediately with plenty of water for at least 15 minutes. Get medical attention if irritation develops and persists
Ingestion: Rinse mouth. Get medical attention immediately.

Fire-fighting measures

Extinguishing media
Suitable extinguishing media: Foam. Dry chemical powder. Carbon dioxide (CO2).
Unsuitable extinguishing medium:Water.
By heating and fire, harmful vapours/gases may be formed.

Special hazards arising from the substance or mixture
Nitrogen oxides. (corrosive)

Advice for firefighters
Firefighters must use standard protective equipment including flame retardant coat, helmet,
gloves, rubber boots, and self-contained breathing apparatus.

Special protective equipment for firefighters
Firefighters must use standard protective equipment including flame retardant coat, helmet, gloves, rubber boots, and self-contained breathing apparatus.

Special fire fighting procedures
Move containers from fire area if you can do so without risk. Water runoff can cause environmental damage.

Accidental release measures

Personal precautions, protective equipment and emergency procedures
For non-emergency personnel: Keep unnecessary personnel away.

Local authorities should be advised if significant spillages cannot be contained
For emergency responders: Wear appropriate personal protective equipment.

Environmental precautions Prevent further leakage or spillage if safe to do so. Avoid release to the environment.

Methods and material for containment and cleaning up
Eliminate sources of ignition.
Large Spills: Stop the flow of material, if this is without risk. Dam the spilled material, where this is possible. Cover with plastic sheet to prevent spreading. Use a non-combustible material like vermiculite, sand or earth to soak up the product and place into a container for later disposal.
Prevent entry into waterways, sewer, basements or confined areas.
Small Spills: Wipe up with absorbent material (e.g. cloth, fleece). Clean surface thoroughly to remove residual contamination.
Never return spills in original containers for re-use.

For personal protection, see section below

Handling and storage

Precautions for safe handling
Provide adequate ventilation. Use care in handling/storage. Do not breathe mist or vapour. Avoid release to the environment. Do not empty into drains.

Conditions for safe storage, including any incompatibilities
Keep container tightly closed. Store in a cool, dry place out of direct sunlight. Store away from incompatible materials (see below). Keep in original container.

Disposal considerations

Waste treatment methods
Residual waste: Dispose of in accordance with local regulations. Empty containers or liners may retain some product residues. This material and its container must be disposed of in a safe manner
Contaminated packaging: Since emptied containers may retain product residue, follow label warnings even after container is
emptied.
EU waste code: The Waste code should be assigned in discussion between the user, the producer and the waste disposal company.
Disposal methods/information:
Incinerate. Incinerator should be appropriately equipped for silica and other fine powder which the product will generate in incineration. Workers should wear appropriate personal protective equipment(s) such as respirator. Contract with a disposal operator licensed by the Law on Disposal and Cleaning. Do not allow this material to drain into sewers/water supplies. Dispose of contents/container in accordance with local/regional/national/international regulations.
