Inhalation: Move individual to fresh air immediately, keep at rest. Provide artificial respiration if breathing stops. Seek medical attention if symptoms persist.
Skin Contact: Wash affected area thoroughly with soap and water. Remove contaminated clothing to prevent further exposure. Seek medical care for persistent irritation or burns.
Eye Contact: Flush eyes with running water for at least 15 minutes, holding eyelids open. Remove contact lenses if needed. Get prompt medical evaluation.
Ingestion: Rinse mouth without inducing vomiting. Give water if conscious. Seek emergency medical help. Monitor for any respiratory or stomach discomfort.
Advice to Emergency Responders: Use appropriate personal protective gear, including gloves and goggles.
Suitable Extinguishers:** Dry chemical, carbon dioxide, foam, water spray can be applied for nearby fires
Unsuitable Extinguishing Media: Direct streams of water on burning liquid may cause spattering
Hazardous Combustion Products: Sulfur oxides, nitrogen oxides, carbon monoxide, carbon dioxide, potentially toxic fumes
Protective Equipment: Wear self-contained breathing apparatus, full protective clothing during fire response
Firefighting Instructions: Move containers from fire area if safe. Apply cooling sprays to exposed containers
Explosion Hazards: Not known to form explosive mixtures but heated closed containers can burst
Personal Precautions: Evacuate area if spillage is large. Wear gloves, goggles, lab coat, and certified respirator as needed.
Environmental Precautions: Block entry into sewers, ditches, or other waterways. Prevent spread to soil and groundwater.
Containment Methods: Surround spill with inert absorbent like vermiculite or sand. Use barriers for containment.
Clean Up Procedures: Scoop or mop liquid into chemical waste containers. Rinse affected area with dilute soap, collect rinsate for disposal.
Decontamination: Dispose of all contaminated materials following local and federal regulations. Wash exposed equipment and skin.
Handling Recommendations: Wear chemical resistant gloves, goggles, lab coats. Avoid inhalation or ingestion, prevent skin and eye contact. Handle only in fume hood or well-ventilated space. Do not eat or drink in handling area.
Storage Requirements: Store in cool, dry, well-ventilated space in tightly sealed containers. Protect from moisture, direct sunlight, high temperatures. Segregate from oxidizers, acids, bases. Keep container upright and labeled.
Incompatibilities: Avoid storage near strong acids, strong bases, strong oxidizers.
Permissible Exposure Limits: No established occupational exposure limits, follow general chemical hygiene practices.
Engineering Controls: Local exhaust ventilation or chemical fume hood recommended.
Personal Protective Equipment: Nitrile or neoprene gloves, safety goggles or face shield, lab coat, closed-toe shoes.
Hygiene Measures: Wash hands before food contact, after handling, and before leaving laboratory.
Respiratory Protection: Use NIOSH-approved respirators during operations likely to generate dust, mist, or vapor.
