General Advice: Remove from exposure, move to fresh air, and keep warm
Inhalation: Move affected person to fresh air. Provide oxygen if breathing is difficult. Seek medical attention if symptoms persist.
Skin Contact: Remove contaminated clothing and wash skin with soap and water. Get medical attention for persistent irritation.
Eye Contact: Rinse cautiously with water for several minutes. Remove contact lenses if present and easy to do. Continue rinsing. Seek medical attention for ongoing pain or vision changes.
Ingestion: Rinse mouth with water, do not induce vomiting unless instructed by medical personnel. Call a poison center or doctor immediately.
Suitable Extinguishing Media: Dry chemical, carbon dioxide, alcohol-resistant foam
Unsuitable Media: Direct stream of water may spread fire.
Specific Hazards: Vapors can form explosive mixtures with air. Containers may rupture if heated.
Protective Equipment: Firefighters require self-contained breathing apparatus and full protective gear.
Special Procedures: Cool exposed containers with water spray. Avoid breathing fumes, vapors, or smoke.
Personal Precautions: Avoid inhalation and contact with skin or eyes. Eliminate all ignition sources. Ensure adequate ventilation.
Protective Equipment: Chemical-resistant gloves, safety goggles, suitable protective clothing.
Spill Response: Absorb spill with inert material (such as sand or vermiculite), then place into a chemical waste container. Contain and collect spillage to prevent entry into waterways.
Environmental Precautions: Prevent further leakage or spillage if safe to do so. Do not discharge into drains or surface waters.
Cleanup Methods: Use non-sparking tools for collection. Dispose of according to local regulations.
Handling: Use only in well-ventilated areas. Keep away from heat, flames, and sources of ignition. Avoid contact with eyes, skin, and clothing. Use recommended PPE.
Storage Conditions: Store in tightly closed container, protected from light and moisture. Keep in cool, dry place, away from incompatible materials such as oxidizers.
Incompatibilities: Strong oxidizers, acids, and bases
Recommended Packaging: Chemically resistant containers, properly labeled.
Exposure Limits: No occupational exposure limits established for this material.
Engineering Controls: Use local exhaust ventilation to minimize vapor concentrations. Emergency shower and eye wash stations should be nearby.
Eye Protection: Chemical safety goggles or face shield.
Skin Protection: Lab coat, chemical-resistant gloves (nitrile recommended).
Respiratory Protection: Use NIOSH/MSHA-approved organic vapor respirator if exposure exceeds limits or ventilation is poor.
Hygiene Measures: Wash hands thoroughly after handling and before eating, drinking, or smoking.
