Inhalation: Move to fresh air, provide oxygen if breathing is difficult, seek immediate medical attention if symptoms such as coughing or shortness of breath persist
Skin Contact: Rinse affected area promptly with plenty of water, remove contaminated clothing, continue rinsing for at least 15 minutes, seek medical attention if irritation continues
Eye Contact: Rinse cautiously with water for several minutes, hold eyelids open to ensure thorough irrigation, remove contact lenses, seek medical attention right away
Ingestion: Rinse mouth with water, do not induce vomiting, seek immediate medical attention, never give anything by mouth to an unconscious person
Most Important Symptoms: Burning sensation, redness, pain, blisters in severe skin contact, vision changes if eye exposure occurs, gastrointestinal distress if swallowed
Suitable Extinguishing Media: Water spray, alcohol-resistant foam, carbon dioxide, dry chemical powder
Unsuitable Extinguishing Media: Do not use high-pressure water jets as these may spread the material
Specific Hazards: Product may emit hazardous fumes such as sulfur oxides and nitrogen oxides when heated or exposed to fire
Special Protective Equipment: Firefighters need self-contained breathing apparatus and full protective gear
Advice for Firefighters: Avoid inhalation of decomposition products, cool containers exposed to fire with water spray, evacuate area if fire grows out of control
Personal Precautions: Avoid direct contact with spilled material, use suitable personal protective equipment including gloves and eye protection, ventilate area
Environmental Precautions: Prevent entry into waterways, drains, or soil, notify authorities if significant spills occur
Clean-Up Methods: Absorb with inert material like sand, collect residue in suitable container, thoroughly clean affected area, dispose of waste according to regulations, wash hands and face after handling
Handling: Handle in well-ventilated spaces, avoid breathing dust or vapors, wear chemical-resistant gloves, safety goggles, and lab coat, do not eat or drink while using product, prevent formation of aerosols
Storage Conditions: Store in tightly sealed original container, place containers in a cool, dry, well-ventilated area, keep away from strong oxidizers, acids, and moisture, avoid temperature extremes
Incompatible Materials: Oxidizing agents, strong acids and bases, water reactive substances
Special Sensitivities: Avoid temperatures exceeding 40°C, keep away from direct sunlight and sources of ignition, label clearly for identification
Engineering Controls: Use with local exhaust ventilation, use fume hood for transfers or reactions, maintain proper airflow in labs
Personal Protective Equipment: Chemically resistant gloves (nitrile or neoprene), safety glasses with side shields or face shield, lab coat or apron, suitable respiratory protection if airborne concentrations rise
Hygiene Measures: Wash thoroughly after handling, remove and wash contaminated clothing before reuse, no smoking, eating, or drinking in work areas
