First Aid Measures

Eye Contact: Flush immediately with clean water for at least 20 minutes, holding eyelids open; immediately seek medical attention
Skin Contact: Remove contaminated clothing, rinse affected skin under running water for at least 20 minutes, obtain medical help; thoroughly wash contaminated clothing before reuse
Inhalation: Remove person to fresh air; assist breathing if necessary; get emergency medical help for symptoms such as cough, wheezing, or shortness of breath
Ingestion: Rinse mouth thoroughly with water, do not induce vomiting; seek immediate medical attention and show safety data sheet to health professionals
Other Important Symptoms: Severe burns on mucous membranes, eyes, respiratory tract; risk of shock or circulatory collapse in severe cases

Fire-Fighting Measures

Suitable Extinguishing Media: Water mist, dry chemical, foam, carbon dioxide
Unsuitable Media: Direct water jets (risk of chemical runoff), avoid using strong streams that could spread the material
Hazardous Combustion Products: Releases nitrogen oxides, carbon oxides, ammonia gas if overheated
Protective Equipment: Wear full chemical protective clothing and self-contained breathing apparatus
Fire and Explosion Hazards: Heats up on contact with strong oxidizers, forms corrosive mixtures; closed containers may rupture in fire
Advice for Firefighters: Approach from upwind, ensure chemical and water runoff does not enter drains or watercourses

Accidental Release Measures

Personal Precautions: Evacuate area, ventilate; wear chemical-resistant gloves, safety goggles, lab coat, and suitable respiratory protection if vapor concentration is high
Environmental Precautions: Do not allow to enter sewage, ground water, or surface water; alert appropriate authorities of major spills
Methods for Containment: Absorb spilled liquid with inert material (such as sand or vermiculite), avoid formation of dust or aerosols
Clean-Up Procedures: Collect absorbed material in a labeled, sealed chemical waste container; wash area with large amounts of water; ensure no chemical residue remains
Disposal: Handle as chemical waste, follow local and national regulation, prevent releases into the environment

Handling and Storage

Handling Precautions: Use only in well-ventilated areas; wear personal protective equipment; avoid splashing, skin and eye contact, or inhalation of vapors
Advice on Safe Handling: Do not eat, drink, or smoke in work area; wash hands before breaks and after handling; keep work surfaces clean
Storage Recommendations: Store in tightly closed original containers, in a cool, dry, well-ventilated space away from heat and direct sunlight
Incompatibilities: Keep separate from acids, oxidizing agents, nitrites, and strong alkalis; separate storage from food and feeds
Special Provisions: Protect containers from physical damage, do not stack more than two levels high, post warning labels clearly

Exposure Controls and Personal Protection

Occupational Exposure Limits: No specific OSHA/ACGIH limits, control exposure to minimal by ventilation
Engineering Controls: Use local exhaust or chemical fume hood; keep concentrations below exposure standards
Personal Protective Equipment (PPE): Chemical-resistant gloves (nitrile or neoprene), safety goggles or face shields, flame-retardant lab coats, long trousers and closed footwear, and use of appropriate respirators for airborne concentrations
Hygiene Measures: Ensure emergency showers and eye wash stations nearby; change contaminated clothes immediately; avoid carrying contaminated clothing outside the work area
Environmental Controls: Prevent chemical from entering the environment, monitor air quality in confined or poorly ventilated areas

Physical and Chemical Properties

Bioaccumulation Potential: Low, due to water solubility and rapid degradation
Mobility in Soil: Expected to be very mobile, contamination of groundwater possible
Other Adverse Effects: Uncontrolled release contributes to eutrophication, temporary reduction in dissolved oxygen in water

Disposal Considerations

Waste Treatment Methods: Collect and transfer to licensed chemical disposal facility
Container Disposal: Triple rinse empty containers, render unusable, dispose as hazardous waste
Contaminated Packaging: Dispose in accordance with official regulations
Discharge Regulation: Do not release into drains, water courses, or soil; follow all governmental and local rules for disposal
