Suitable Extinguishing Media: Water spray, dry chemical, carbon dioxide, foam
Unsuitable Extinguishing Media: High volume water jet may spread material
Specific Hazards: May release toxic fumes of hydrochloric acid, nitrogen oxides, carbon monoxide, and carbon dioxide on thermal decomposition
Protective Equipment: Firefighters must wear full protective gear and self-contained breathing apparatus
Advice for Firefighters: Avoid inhaling combustion gases, use water spray to cool containers, prevent runoff from entering sewers or natural water
Personal Precautions: Utilize personal protective equipment such as gloves, goggles, lab coat or apron; ensure adequate ventilation
Environmental Precautions: Prevent product from entering drains, surface water, or soil
Spill Cleanup: Absorb with inert material like sand, scoop up and place in suitable container for disposal; ventilate contaminated area; wash spill area with water to remove residues
Methods for Containment: Enclose spill and prevent spreading, use non-sparking tools
Safe Handling: Avoid contact with eyes, skin, and clothing; avoid inhalation of dust, mist, or fumes; do not eat, drink, or smoke when using the substance; wash hands thoroughly after handling
Storage Conditions: Store in tightly closed container in well-ventilated, dry, cool location out of direct sunlight; segregate from incompatible materials such as strong oxidizers and acids; label shelves with chemical identification
Incompatible Materials: Strong oxidizers, strong acids, reactive metals may initiate hazardous reactions
Special Precautions: Secure storage area to prevent unauthorized access, monitor temperature to avoid exceeding recommended storage limits
Exposure Limits: No established OSHA or ACGIH limits specific to Benzyltrimethylammonium Chloride
Engineering Controls: Use local exhaust or general room ventilation to keep airborne levels below recommended limits; utilize closed systems where practical
Personal Protective Equipment: Chemical-resistant gloves (nitrile or rubber), safety goggles, lab coat, face shield if splash risk exists
Respiratory Protection: Use approved respirators in poorly ventilated spaces, for dusty operations, or if process creates mist or aerosol
Hygiene Measures: Remove contaminated clothing immediately, wash thoroughly after handling, do not eat or drink near the work area

Respiratory Sensitization: Exposure to dust or mist may cause respiratory tract irritation
Germ Cell Mutagenicity: Data insufficient, no evidence of genotoxicity in available studies
Carcinogenicity: Not listed as a carcinogen by IARC, NTP, or OSHA
Reproductive Toxicity: No evidence in available literature
Potential Effects of Chronic Exposure: Prolonged skin contact could promote dermatitis or sensitivity in rare cases, high doses over time can affect liver and kidney in repeated animal dosing experiments
Ecotoxicity: Harmful to aquatic organisms at high concentrations; estimated LC50 for fish ranges from 1–10 mg/L in various studies
Persistence and Degradability: Limited persistence in well-oxygenated environments, breaks down by hydrolysis and microbial action
Bioaccumulative Potential: Low potential based on chemical structure and water solubility
