Classification, hazard (H) and precautionary (P) statements and pictograms per OSHA HCS 2024 (29 CFR 1910.1200, Appendices A–C), aligned with GHS Rev. 7.

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

Eyes

Rinse with plenty of water for at least 15 minutes. Remove contact lenses if present and easy to do. Continue rinsing. Seek medical attention immediately.

Skin

Immediately flush with plenty of water for at least 15 minutes while removing contaminated clothing. Wash with soap. Get medical attention immediately.

Inhalation

Move person to fresh air and keep comfortable for breathing. If breathing is difficult, give oxygen. If not breathing, give artificial respiration. Get medical attention immediately.

Ingestion

Do Not Induce Vomiting! Never give anything by mouth to an unconscious person. If conscious, wash out mouth with water. Get medical attention immediately.

Most Important Symptoms and Effects

• Ingestion may cause nausea, vomiting and abdominal pain; larger amounts may cause systemic poisoning.
• Absorption through the skin may cause systemic poisoning.
• Inhalation may cause coughing, shortness of breath and headache; high concentrations may cause systemic poisoning.
• A single exposure may damage organs.

Immediate Medical Attention and Special Treatment

• Get immediate medical attention after any significant exposure; symptoms may be delayed.

Suitable Extinguishing Media

Alcohol-resistant foam, CO2, dry chemical powder. Water spray may be used to cool fire-exposed containers.

Unsuitable Extinguishing Media

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

Specific Hazards Arising from the Chemical

Vapors are heavier than air and may form explosive mixtures with air; they can travel to a source of ignition and flash back. Containers may rupture when heated.

Protective Equipment

Wear self-contained breathing apparatus and full protective clothing.

Hazardous Combustion Products

Carbon monoxide, carbon dioxide and formaldehyde.

Personal Precautions

Use PPE as described in Section 8. Ensure adequate ventilation. Evacuate personnel to safe areas.

Hazard-Specific Precautions

Eliminate all ignition sources. Use non-sparking tools and explosion-proof equipment; ground and bond containers during cleanup.

Environmental Precautions

Prevent leakage or spillage from entering drains, sewers, or waterways.

Containment & Cleanup

Absorb with inert material. Collect in appropriate waste container. Dispose per applicable 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 away from heat, sparks, and open flame. Keep away from incompatible materials (see Section 10). Keep containers tightly closed. Ground and bond containers when transferring material.

Specific Storage Precautions

Keep containers tightly closed in a cool, dry, well-ventilated flammables area away from heat, sparks, open flame and direct sunlight. Store locked up. Ground and bond containers when transferring.

Occupational Exposure Limits

Engineering Controls

Use adequate ventilation. Provide eyewash stations and quick-drench showers accessible to areas of use.

Eye/Face Protection

Wear chemical safety goggles or face shield.

Skin Protection

Wear chemical-resistant gloves and protective clothing.

Respiratory Protection

Use a NIOSH-approved respirator with organic vapor cartridges. For confined spaces or exposures above the OEL, use supplied-air respiratory protection.

Exposure limits sourced from NIOSH Pocket Guide, OSHA 29 CFR 1910.1000 and ACGIH TLVs.
