Other Components: No other constituents present that influence the classification of the product
Inhalation: Move person to fresh air without delay. If symptoms appear, provide oxygen and seek medical help.
Skin Contact: Immediately wash off with plenty of water for at least 15 minutes, remove contaminated clothing, seek attention if irritation persists.
Eye Contact: Rinse carefully with water for several minutes; continue if user is wearing contact lenses, make sure to remove them if easy to do.
Ingestion: Rinse mouth thoroughly, drink water if conscious, never induce vomiting unless directed by medical staff. Call physician or poison control at once.
Notes for Physicians: Treat symptomatically, no specific antidote exists.
Suitable Extinguishing Media: Use dry chemical, carbon dioxide, or alcohol-resistant foam. Water spray can be used to cool containers, but direct stream may scatter material.
Unsuitable Media: Do not use high-pressure water jet directly on burning substance.
Specific Hazards: May emit toxic fumes of hydrogen chloride, nitrogen oxides, or carbon monoxide under fire.
Protective Equipment for Firefighters: Wear full protective gear and self-contained breathing apparatus.
Additional Advice: Move containers from fire area if it can be done safely, prevent runoff from reaching sewers or watercourses.
Personal Precautions: Use appropriate respiratory protection, prevent direct contact with skin or eyes, ventilate the spill area.
Environmental Precautions: Do not allow to enter sewers, surface, or groundwater; prevent further leakage if safe.
Containment Methods: Sweep up and place in an appropriate waste container using tools that do not generate dust.
Cleaning Methods: Wash area with copious amounts of water after material removal. Ensure waste is disposed of properly and legally.
Safe Handling: Handle in an area with adequate ventilation, use local extraction if available, avoid dust creation, minimize direct contact.
Safe Storage: Keep in tightly sealed containers, store away from incompatible materials like oxidizers and acids, maintain storage temperature below 25°C, keep out of direct sunlight.
Specific Requirements: Label storage clearly, ensure secondary containment if storing large quantities.
Occupational Exposure Limits: No specific national or ACGIH exposure limit set for Dimethylamine Hydrochloride itself, but respect general nuisance dust limits: typically 10 mg/m³ (total dust), 3 mg/m³ (respirable) as an 8-hour TWA.
Engineering Controls: Use fume hoods, ventilation systems, dust extraction units.
Personal Protective Equipment: Wear nitrile or neoprene gloves, safety goggles with side shields, lab coats or full-coverage clothing.
Respiratory Protection: Use dust mask or respirator (N95 or better) if airborne dust expected.
Hygiene Measures: Do not eat or drink in work areas; change and launder clothing regularly after use.
