Chemical Name: Myristylpyridinium Bromide
Concentration: 98% or higher by weight
Synonyms: 1-Tetradecylpyridinium Bromide
Impurities: Typically contains trace levels of related pyridinium compounds, presence varies by synthesis batch
Molecular Weight: 356.38 g/mol

Inhalation: Move to fresh air, provide oxygen if breathing is difficult, seek medical help if symptoms persist
Skin Contact: Flush exposed skin with large amounts of water, remove contaminated clothing, seek medical attention for persistent irritation
Eye Contact: Rinse eyes gently with water for at least 15 minutes, lift eyelids occasionally, get immediate medical aid
Ingestion: Rinse mouth, do not induce vomiting, drink water if conscious, get immediate medical advice
Most Important Symptoms: Severe irritation, redness, burns, pain, possible systemic toxicity

Suitable Extinguishing Media: Use water spray, dry chemical powder, foam, carbon dioxide for small fires
Unsuitable Media: Direct water jet could spread material
Hazards from Combustion: Produces toxic fumes including hydrogen bromide, carbon oxides, nitrogen oxides
Protective Equipment: Firefighters need full protective clothing and self-contained breathing apparatus
Special Procedures: Keep containers cool with water spray, contain contaminated run-off to prevent entry into drains

Personal Precautions: Wear chemical-resistant gloves, protective clothing, and goggles; provide adequate ventilation
Environmental Precautions: Prevent entry into sewers, rivers, and soil; contain spill using inert absorbent such as sand or earth
Cleanup Methods: Sweep up without creating dust, place in clearly labeled container for disposal; clean residue with water
Decontamination: Wash affected area with plenty of water after cleanup, ventilate area before reuse

Handling: Avoid prolonged or repeated skin contact, wear proper personal protective equipment, keep contained to avoid generation of dust
Storage: Store in tightly closed containers, in a cool, dry, well-ventilated place, away from incompatible substances such as strong oxidizers and acids
Incompatibilities: Strong acids, strong bases, and oxidizing agents can cause dangerous reactions
Specific Requirements: Label shelves and containers clearly, keep away from food and drink materials

Exposure Limits: No established occupational exposure limits for this substance; minimize exposure by engineering controls
Engineering Controls: Use local exhaust ventilation, safety showers, and eyewash stations in the immediate work area
Personal Protection: Wear gloves (nitrile or neoprene), safety glasses with side-shields, lab coats or protective coveralls
Respiratory Protection: Use properly fitted particulate respirator where airborne dust exceeds acceptable levels
