Concentration: Up to 100%
Impurities: May contain traces of stabilizers or solvents depending on supplier
Formulation: Often supplied as a liquid, sometimes diluted with an appropriate non-reactive solvent
Other Components: Additives intended for shelf stabilization
Inhalation: Remove to fresh air. Support breathing with artificial respiration if needed. Seek medical attention if symptoms persist.
Skin Contact: Remove contaminated clothing. Rinse skin with copious amounts of water for at least 15 minutes. Apply mild soap and seek medical help if irritation develops.
Eye Contact: Rinse cautiously with water for at least 15 minutes while holding eyelids open. Remove contact lenses if present and easy to do. Continue rinsing, seek medical advice.
Ingestion: Rinse mouth with water. Do not induce vomiting. Call medical personnel immediately.
General Advice: Show label and SDS to physician. Document exposure incident for workplace safety follow-up.
Suitable Extinguishing Media: Water spray, foam, dry chemical powder. Prefer water to cool containers and prevent explosion.
Unsuitable Media: Carbon dioxide due to poor cooling effect on organic peroxides.
Special Hazards: Product may self-ignite at elevated temperatures. Explosion risk if heated or contaminated.
Hazardous Combustion Products: Carbon monoxide, carbon dioxide, acetic acid, tert-butanol, other volatile organics.
Advice for Firefighters: Wear self-contained breathing apparatus and protective gear. Fight fire from upwind and avoid inhaling combustion products. Keep containers cool with spray to prevent rupture. Isolate area and remove bystanders.
Personal Precautions: Evacuate area and ventilate. Do not touch spilled material. Use chemical-resistant gloves, goggles, protective clothing. Prevent contact with skin, eyes, and clothing.
Environmental Precautions: Prevent runoff into drains, surface water, soil. Inform authorities in case of large releases.
Containment: Build dikes using inert materials. Do not use combustible absorbents.
Cleanup: Absorb with sand, vermiculite, or other inert material. Place in a closed, labeled, compatible container for disposal. Wash spill site with water, ventilate area. Decontaminate tools and equipment before re-use.
Handling Practices: Wear appropriate personal protective equipment. Avoid contact with incompatible materials such as reducing agents, acids, bases, or combustibles. Keep away from ignition sources. Use in well-ventilated areas. Prevent static build-up.
Storage Requirements: Store in original, tightly-closed container, away from direct sunlight, heat, flame, sparks, and incompatible materials. Store below 25°C (77°F). Designate special storage area with appropriate signage. Segregate from flammable substances.
Other Precautions: Regularly inspect containers for signs of pressure buildup or leaks.
Engineering Controls: Local exhaust ventilation. Closed systems or fume hoods recommended for transfer and processing.
Personal Protection: Chemical-resistant gloves (nitrile, neoprene), safety goggles or full face shield, flame-resistant clothing, appropriate chemical-resistant footwear.
Respiratory Protection: Use air-purifying respirators with organic vapor cartridge if exposure limits exceeded.
Work Practices: Do not eat, drink, or smoke during use. Wash hands after handling.
Environmental Exposure Controls: Employ secondary containment to prevent environmental release.
