Concentrations are nominal; lot-specific values appear on the Certificate of Analysis. Components not contributing to classification are omitted.

Eyes

Rinse with water. Get medical attention if irritation develops or persists.

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

Acrolein (a severe irritant) when overheated; carbon monoxide and carbon dioxide on combustion.

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

Keep tightly closed (hygroscopic) in a dry place away from strong oxidizers. Stainless steel, aluminum or polyethylene containers.

Occupational Exposure Limits

Engineering Controls

General ventilation is normally adequate.

Eye/Face Protection

Safety glasses are recommended.

Skin Protection

Gloves are recommended for prolonged or repeated contact.

Respiratory Protection

Not normally required.
