Inhalation: Move exposed person to fresh air, provide oxygen if breathing is difficult, seek medical attention for persistent symptoms
Skin Contact: Wash area with soap and plenty of water, remove contaminated clothing, seek medical advice if long-lasting irritation occurs
Eye Contact: Rinse patiently with water for several minutes, lift eyelids to clear all residues, seek medical advice if pain or vision issues remain
Ingestion: Rinse mouth, never induce vomiting, get immediate medical attention, monitor for nausea or stomach discomfort
Note to Physician: Treat symptomatically, monitor respiratory and cardiac functions; no specific antidote identified
Suitable Extinguishing Media: Water spray, dry chemical powder, carbon dioxide, foam depending on fire location
Specific Hazards: Combustion produces hazardous gases including hydrogen bromide, nitrogen oxides, carbon monoxide; dense smoke; containers heated by fire may burst
Protection for Firefighters: Full protective gear, self-contained breathing apparatus; prevent runoff from entering drains and watercourses
Firefighting Instructions: Remove containers from fire area if safely possible, cool uneffected containers with water spray
Personal Precautions: Evacuate area, limit access, wear suitable protective equipment including gloves, goggles, and respiratory protection
Environmental Precautions: Prevent product from entering water systems, spills into drains or soil must be contained immediately
Cleanup Methods: Contain and collect spillage with inert absorbent material (sand, earth), place in a chemical waste container, ventilate area, wash remaining residues with copious water, dispose of contaminated material following regulations
Handling: Use in a chemical fume hood, avoid formation of dust, avoid direct contact with eyes, skin, and clothing, never eat, drink, or smoke in areas where chemicals are handled
Storage: Store tightly closed in a cool, dry, and well-ventilated area, keep away from incompatible materials such as acids and oxidizing agents, store in containers clearly labeled, protect from sunlight and heat sources, keep out of reach of children and unauthorized personnel
Engineering Controls: Use local exhaust ventilation, chemical fume hoods to minimize exposure
Respiratory Protection: Approved filter respirators for fumes and dust if airborne exposure may occur
Eye Protection: Tight-fitting safety goggles or face shield
Skin Protection: Chemical-resistant gloves (nitrile or neoprene), laboratory coat, long sleeves
Hygiene Measures: Wash hands, face, and exposed skin thoroughly after handling, remove contaminated clothing and wash before reuse
Exposure Limits: No occupational exposure limits established, minimize exposure as much as practical following ALARA (As Low As Reasonably Achievable) principle

Hazardous Reactions: Incompatible with strong oxidizers and strong acids causing decomposition reactions
Hazardous Decomposition Products: Hydrogen bromide, nitrogen oxides, carbon monoxide and carbon dioxide on combustion
Conditions to Avoid: Excess heat, open flame, moisture, direct sunlight, exposure to acidic or oxidizing materials
Acute Toxicity: Harmful if swallowed, irritant to skin and eyes, moderate toxicity by inhalation
Skin Corrosion/Irritation: Causes redness, burning, and dryness after prolonged or repeated contact
Serious Eye Damage/Irritation: Eye contact leads to pain, tearing, temporary injury
Sensitization: Potential to trigger allergic skin response on repeated exposure
Mutagenicity: No conclusive data, exercise caution with all pyridinium salts
Carcinogenicity: No classification by IARC, OSHA, or NTP
Reproductive Toxicity: Not listed as reproductive toxin; data insufficient for a final assessment
Inhalation Symptoms: Coughing, shortness of breath, possible respiratory irritation
Ingestion Risks: Gastrointestinal discomfort, nausea, vomiting, abdominal pain
Delayed and Immediate Effects: High concentrations lead to symptoms after latency period, prompt medical attention essential
Aquatic Toxicity: Greatly toxic to aquatic organisms, risk of persistent environmental effects
Degradability: Limited biodegradation by standard environmental bacteria, persistent in surface waters
Bioaccumulative Potential: Evidence indicates moderate potential due to cationic surface activity
Mobility in Soil: Moderately mobile but adsorbs to soils with high organic matter
Other Adverse Effects: Avoid uncontrolled discharge into the environment, impacts in surface water persist and harm aquatic invertebrates
Product Disposal: Dispose as hazardous waste following national and local regulations; incineration at high-temperature facilities recommended
