Ingredients Contribution to Hazard: Imidazolium salts are known irritants
Eye Contact: Rinse gently with water for 15 minutes, remove contact lenses, seek medical attention
Skin Contact: Wash thoroughly with soap and water, remove contaminated clothing, seek help if irritation develops
Inhalation: Move to fresh air, provide oxygen if breathing is difficult, consult a healthcare provider
Ingestion: Rinse mouth, drink water, seek emergency medical care, do not induce vomiting
General Advice: Take SDS to the clinic, describe the exposure and symptoms clearly, watch for delayed symptoms
Suitable Extinguishing Media: CO2, dry chemical, alcohol-resistant foam
Unsuitable Media: Direct water stream may spread chemicals
Special Hazards: Combustion may form toxic fumes—carbon monoxide, nitrogen oxides, hydrogen bromide
Protective Equipment: Wear full protective clothing, self-contained breathing apparatus
Firefighting Instructions: Contain runoff, avoid inhalation of gases, remove undamaged containers if safe
Combustibility: May support combustion but unlikely to ignite easily under standard storage
Personal Precautions: Avoid direct contact, ventilate area, use protective clothing and gloves
Environmental Precautions: Prevent entry into water systems, drains, and soil
Methods for Clean-up: Absorb with non-combustible material such as sand, collect in chemical waste containers, wash residues with water
Containment Techniques: Isolate spill area, minimize spread, use barriers when appropriate
Decontamination: Surface clean with detergent and flush with copious water
Handling: Use chemical fume hood, wear personal protective equipment, avoid spills and aerosol generation
Hygiene Measures: Wash hands before meals, avoid eating or drinking in work area, change contaminated clothing promptly
Storage Conditions: Store in cool, well-ventilated area, keep container tightly closed
Incompatibles: Strong oxidizers, strong acids, reactive metals
Shelf Life: Stable under recommended storage, avoid extended exposure to air or sunlight
Packaging: Use tightly sealed, labeled containers resistant to corrosion
Occupational Exposure Limits: No established OSHA or ACGIH limits specific to AOIB
Engineering Controls: Use fume hood, local exhaust ventilation
Personal Protection: Safety glasses or goggles, impervious gloves (nitrile recommended), lab coat or coveralls
Respiratory Protection: Use NIOSH-approved respirator for dusts or mists if aerosol risk exists
Environmental Controls: Use closed systems or suitable exhaust, avoid releases outside workplace containment
Monitoring: Employ regular checks for chemical exposure in high-use labs
Appearance: Pale yellow to white solid or semi-solid

Hazardous Reactions: Can form toxic or corrosive gases with strong acids or oxidizers
Decomposition Products: Carbon oxides, imidazole derivatives, hydrogen bromide gas
Conditions to Avoid: Excessive heat, open flame, sources of ignition, alkaline environments
Acute Toxicity (Oral): LD50 not precisely known, harmful if ingested—gastrointestinal symptoms, oral and throat irritation
Acute Toxicity (Dermal): Prolonged exposure may cause moderate skin irritation
Inhalation: Dusts or aerosols may induce coughing, shortness of breath, nasal irritation
Chronic Effects: Repeated or prolonged exposure may lead to dermatitis, no known carcinogenicity
Sensitization: Not established, watch for delayed onsets
Symptoms of Overexposure: Nausea, vomiting, redness or soreness at site of contact
Aquatic Toxicity: Not classified, but imidazolium compounds documented to pose hazard for water organisms at higher concentrations
Persistence and Degradability: Slow biodegradation expected, can persist under low-oxygen conditions
Bioaccumulative Potential: Limited, due to moderate solubility and structure
Mobility in Soil: Moderately mobile, partitioning depends on environmental pH
Other Adverse Effects: Avoid direct discharge, always adhere to local environmental rules
