Skin

Wash with soap and water. Get medical attention if irritation develops.

Inhalation

Move to fresh air if discomfort occurs.

Ingestion

Rinse mouth with water. Get medical attention if you feel unwell.

Most Important Symptoms and Effects

• No specific symptoms are expected from the hazards identified in Section 2.

Immediate Medical Attention and Special Treatment

• Treat symptomatically. Get medical attention if symptoms develop or persist.

Suitable Extinguishing Media

Use water spray, alcohol-resistant foam, dry chemical, or CO2. Use measures appropriate to local circumstances.

Unsuitable Extinguishing Media

Do not use a solid water stream as it may scatter and spread fire.

Specific Hazards Arising from the Chemical

Containers may rupture when heated.

Protective Equipment

Wear self-contained breathing apparatus and full protective clothing.

Hazardous Combustion Products

Carbon monoxide, carbon dioxide, nitrogen oxides and ammonia on thermal decomposition; cyanuric acid may also form.

Personal Precautions

Wear safety glasses and gloves for cleanup. Spills can make floors slippery.

Environmental Precautions

Avoid releasing large quantities to drains or waterways.

Containment & Cleanup

Absorb or wipe up, then rinse the area with water. Dispose of according to local regulations.

Safe Handling

Use with adequate ventilation. Avoid contact with skin, eyes, and clothing. Wash thoroughly after handling. Keep container closed when not in use.

Safe Storage

Store in a cool, dry, well-ventilated area. Keep away from incompatible materials (see Section 10). Keep containers tightly closed.

Specific Storage Precautions
