Inhalation: Move person to fresh air. Seek medical attention if symptoms appear such as cough, dizziness, or shortness of breath.
Skin Contact: Remove contaminated clothing. Wash area thoroughly with soap and water for at least 15 minutes.
Eye Contact: Rinse cautiously with water for several minutes. Remove contact lenses if present and easy to do. Continue rinsing. Seek medical advice if irritation persists.
Ingestion: Rinse mouth. Do not induce vomiting. Get medical help or call a poison center for guidance.
Symptoms: Irritation, coughing, burning eyes, headache, nausea
Suitable Extinguishing Media: Alcohol-resistant foam, dry chemical, carbon dioxide, water spray (do not use water jet)
Specific Hazards: Vapors may form explosive mixtures with air. May emit toxic fumes of carbon monoxide, carbon dioxide under combustion.
Protective Equipment: Firefighters use full protective gear and self-contained breathing apparatus.
Special Procedures: Cool closed containers with water spray to prevent pressure build-up. Evacuate area and control runoff to prevent environmental contamination.
Personal Precautions: Ventilate the area. Remove ignition sources. Wear appropriate personal protective equipment such as gloves and goggles. Avoid contact with skin and eyes.
Environmental Precautions: Prevent further leakage or spillage if safe to do so. Avoid discharge into drains, surface water, or soil.
Methods for Clean-Up: Absorb with inert material such as dry sand or earth, collect in suitable container. Wash spill area with detergent and water.
Handling: Handle in a well-ventilated space. Keep containers tightly closed. Ground all equipment containing material. Avoid inhaling vapors or mist.
Storage: Store in a cool, dry, well-ventilated area away from heat sources and open flames. Keep storage container tightly sealed. Store away from incompatible substances such as strong oxidizers and acids.
Exposure Limits: No specific occupational exposure limits established for this substance as of current regulations.
Engineering Controls: Use local exhaust ventilation. Provide safety showers and eyewash stations.
Personal Protection: Wear chemical splash goggles, impervious gloves, and protective clothing. Use a NIOSH-approved respirator if exposure limits are exceeded or symptoms develop.
Hygiene Measures: Always wash hands before breaks and after handling the material. Remove and wash contaminated clothing before reuse.
