Inhalation: Move person to fresh air quickly, keep at rest, call medical attention if symptoms like cough or shortness of breath appear
Skin Contact: Remove contaminated clothing, wash skin thoroughly with soap and water for at least 15 minutes, obtain medical help for persistent irritation
Eye Contact: Immediately rinse eyes with plenty of water for at least 15 minutes, keep eyelids apart to ensure thorough rinsing, seek immediate medical attention
Ingestion: Do not induce vomiting, rinse mouth with water, seek immediate medical advice, give nothing by mouth unless instructed by medical personnel
Most Important Symptoms: Irritation, redness, pain, coughing, possible headache, abdominal discomfort
Medical Attention: Provide medical professionals with relevant chemical information
Suitable Extinguishing Media: Water spray, dry chemical powder, foam, carbon dioxide
Unsuitable Media: Direct water jets may spread the chemical
Fire Hazards: Vapors may form explosive mixtures with air, thermal decomposition releases toxic fumes (nitrogen oxides, carbon oxides)
Special Equipment: Wear self-contained breathing apparatus, full protective clothing, approach from upwind side
Firefighter Precautions: Isolate fire area, use water spray to cool containers, avoid inhaling fumes
Hazardous Decomposition: Carbon monoxide, carbon dioxide, nitrogen oxides
Personal Protection: Wear chemical-resistant gloves, eye protection, lab coat, use proper respiratory protection if exposure risk exists
Environmental Precautions: Avoid release into the environment, prevent entry into drains, waterways, or soil
Cleanup Methods: Ventilate area, confine spill, absorb with inert material (sand, vermiculite), collect in chemical waste container, wash spill site after material pickup
Containment: Prevent spillage from entering water systems, secure area around the spill
Decontamination: Clean contaminated surfaces thoroughly, ensure proper removal of residue
Handling: Use in well-ventilated areas, avoid breathing vapors, prevent contact with skin and eyes, employ good chemical hygiene
Storage Conditions: Keep container tightly closed in cool, dry, well-ventilated place, store away from incompatible materials (strong oxidizers, acids), protect from direct sunlight
Incompatible Materials: Strong oxidizing agents, acids, acid chlorides
Transfer Operations: Minimize dust and vapor generation, avoid static discharge, ground all equipment
Hygiene Suggestions: Wash hands after handling, no eating, drinking, or smoking near product
Exposure Limits: No specific occupational exposure limits established, handle as hazardous chemical
Engineering Controls: Use local exhaust ventilation, process enclosures, or mechanical ventilation to control airborne levels
Respiratory Protection: Use NIOSH/MSHA approved respirators where vapor concentration is high
Skin Protection: Chemical-resistant gloves (nitrile, neoprene), long-sleeved clothing
Eye Protection: Chemical splash goggles, face shield if splashing risk increases
Other Protective Measures: Emergency eye wash, safety shower near work area, remove contaminated clothing
