First Aid Measures

Inhalation: Move to fresh air, seek medical attention if symptoms persist, such as difficulty breathing or persistent coughing
Skin Contact: Remove contaminated clothing and wash affected area thoroughly with soap and water, seek attention if skin continues to feel irritated
Eye Contact: Rinse cautiously with water for several minutes, remove contact lenses when present and continue rinsing, get immediate help for redness, pain, or vision changes
Ingestion: Rinse mouth, do not induce vomiting unless told by medical personnel, get help if swallowed and symptoms like nausea or abdominal discomfort persist
General Advice: Show label and this sheet to emergency responders for quick reference during first aid

Fire-Fighting Measures

Suitable Extinguishing Media: Use water spray, alcohol-resistant foam, dry chemical, or carbon dioxide extinguishers
Unsuitable Media: Direct water jets can spread burning liquid
Special Hazards: Combustion can yield carbon oxides and irritant fumes; containers exposed to fire may rupture
Protective Equipment for Firefighters: Full protective gear and self-contained breathing apparatus to avoid inhaling vapors or combustion products
Fire-Fighting Instructions: Keep cool with water spray, avoid spreading runoff to drains or water sources

Accidental Release Measures

Personal Precautions: Wear respiratory protection, chemical goggles, gloves, and work clothing
Environmental Precautions: Prevent product from entering sewer, waterways, or soil by diking with non-combustible material
Containment Methods: Stop leak if it is safe, use inert absorbent (sand or earth) to soak up spilled liquid
Clean-up Procedures: Collect absorbed material in sealed containers for disposal, ventilate area, avoid creating mist or aerosol during cleanup

Handling and Storage

Handling: Avoid contact with skin, eyes, and clothing, do not breathe vapor or mist, use only in well-ventilated spaces, keep away from sources of ignition, wash hands after handling
Storage: Store in tightly sealed original containers away from direct sunlight and incompatible substances, in cool, dry places
Incompatible Materials: Strong oxidizers, acids, alkalis
Other Considerations: Keep container upright to prevent leakage; label all containers clearly for workplace safety

Exposure Controls and Personal Protection

Occupational Exposure Limits: No established ACGIH or OSHA limits; employer should use good industrial hygiene controls
Engineering Controls: Provide adequate mechanical ventilation, especially in enclosed work areas
Respiratory Protection: Use NIOSH-approved mask if airborne vapors or mists are likely
Eye Protection: Chemical splash goggles
Hand Protection: Butyl rubber or nitrile gloves
Other Protective Equipment: Long sleeves, closed shoes, and face shield during possible splash risk
