Inhalation: Move the person to fresh air. Seek medical attention for persistent symptoms such as coughing, wheezing, shortness of breath, or dizziness. Oxygen or artificial respiration may be needed.
Skin Contact: Remove contaminated clothing and shoes quickly. Wash with copious amounts of water and mild soap. If irritation or redness persists, see a doctor.
Eye Contact: Rinse opened eyes thoroughly with running water for at least 15 minutes, holding eyelids apart. Do not rub the eyes. Remove contact lenses if present and easy to do. Get medical attention immediately.
Ingestion: Rinse mouth well with water. Do not induce vomiting. Give small amounts of water to dilute. Never give anything by mouth to an unconscious person. Seek immediate medical care.
Suitable Extinguishing Media: Use CO2, alcohol-resistant foam, dry chemical, or water spray.
Special Hazards: Vapors may form flammable mixtures with air. Can release hazardous fumes such as nitrogen oxides, carbon monoxide, and amines under fire conditions. Containers can burst if exposed to extreme heat.
Protective Equipment: Firefighters should wear self-contained breathing apparatus and full protective gear.
Fire-Fighting Instructions: Evacuate area. Fight fire from upwind. Cool nearby containers with water spray. Do not allow runoff from fire control to enter drains or watercourses.
Personal Precautions: Ventilate area. Avoid breathing vapors or mist. Remove all sources of ignition. Wear chemical splash goggles, gloves, and suitable protective clothing.
Methods for Cleanup: Stop leak if safe to do so. Dike spilled material with inert absorbent (sand, earth, vermiculite). Collect into containers for disposal. Wash area with water after clean-up. Prevent entry into sewers, basements, or confined spaces.
Environmental Precautions: Prevent release into the environment. Notify authorities if large spills reach watercourses or sewers.
Handling: Use only in well-ventilated areas. Keep away from heat, sparks, open flames, and hot surfaces. Use spark-proof tools. Avoid all contact with skin, eyes, and clothing. Wear protective gear. No smoking near chemicals.
Storage: Store in tightly sealed original container. Keep in a cool, dry, well-ventilated place away from incompatible materials such as acids and oxidizing agents. Protect from sunlight. Store away from food and drink.
Specific Requirements: Follow regulations for flammable liquids. Keep storage containers grounded and bonded.
Engineering Controls: Provide local exhaust ventilation, especially where vapors or aerosols may be generated.
Eye Protection: Chemical goggles or face shield.
Skin Protection: Impervious gloves. Long-sleeved clothing. Chemical resistant boots.
Respiratory Protection: Use approved respirators if exposure limits are exceeded or in case of inadequate ventilation.
Workplace Monitoring: Regular air monitoring for amine vapors. Ensure emergency eyewash and safety shower stations are accessible.
Environmental Controls: Prevent leakages to the environment. Use containment to avoid soil and water contamination.
