Most Important Symptoms and Effects: Irritation of mucous membranes, burning sensation in eyes, coughing and breathlessness after inhalation, abdominal discomfort following ingestion
Suitable Extinguishing Media: Use dry chemical powder, foam, carbon dioxide, or water spray as appropriate for surrounding fire
Specific Hazards Arising: Fumes of nitrogen oxides, sulfur oxides, hydrochloric acid gas, and possibly carbon oxides during combustion
Protective Equipment for Firefighters: Use self-contained breathing apparatus, chemical-resistant clothing, and gloves; avoid breathing in vapors
Special Firefighting Procedures: Contain water runoff; prevent entry to water sources; cool fire-exposed containers
Personal Precautions: Wear splash goggles, chemical-resistant gloves, and protective clothing to prevent direct exposure; avoid raising dust
Environmental Precautions: Prevent spillage from entering drains and surface water; collect spilled product with inert absorbent material; dispose of in designated chemical waste containers
Methods for Cleanup: Ventilate affected area; collect solid with non-sparking tools; wash area with water and detergent; package waste in clearly labeled containers
Handling: Work in a well-ventilated space; avoid skin and eye contact and inhalation of powder or solutions; keep containers tightly sealed when not in use; do not eat, drink, or smoke near chemical
Storage Conditions: Store in a dry, cool, well-ventilated area away from direct sunlight and incompatible materials; maintain temperature between 2°C and 8°C for long-term stability; segregate from strong acids, alkalis, and oxidizing agents
Packaging Materials Recommended: Use high-density polyethylene or glass containers with tight-fitting lids
Engineering Controls: Employ fume hoods and efficient local exhaust ventilation to maintain airborne concentrations below occupational limits
Personal Protection: Safety glasses with side shields, chemical-resistant gloves (nitrile or neoprene), protective clothing with long sleeves
Respiratory Protection: Provide NIOSH-approved respirators if dust, vapor, or aerosol formation exceeds recommended exposures
Hygiene Measures: Wash hands and forearms thoroughly after handling; refrain from touching face, eyes, or mouth when operating with open containers
Occupational Exposure Limit: Not established for this substance; minimize exposure as much as possible

Incompatible Materials: Strong oxidizing agents, strong acids, strong alkali solutions
Decomposition Products: Releasing toxic and corrosive fumes such as HCl, NOx, SOx upon heating or combustion
Conditions to Avoid: Elevated temperature, moisture, exposure to light and humidity
Possibility of Hazardous Reactions: No hazardous polymerization likely under normal circumstances
Likely Routes of Exposure: Inhalation, ingestion, skin and eye contact
Acute Toxicity Data: Oral LD50 (rat): Not specifically measured; similar compounds suggest moderate toxicity if ingested
Skin Corrosion/Irritation: Causes moderate irritation on prolonged or repeated contact
Serious Eye Damage/Irritation: May provoke redness, tearing, pain in exposed eyes
Respiratory Effects: Irritation, coughing, sneezing after inhaling fine particles
Chronic Effects: No long-term studies available; chronic exposure not advised due to potential cumulative irritation
Carcinogenicity, Mutagenicity, Reproductive Toxicity: No evidence from animal studies to classify as a carcinogen, mutagen, or reproductive toxicant
Aquatic Toxicity: Expected to exhibit moderate toxicity to aquatic organisms based on structural analogues; no standardized test data available
Mobility in Soil: High solubility in water increases potential for migration through soil and water columns
Persistence and Degradability: May not rapidly biodegrade; care required to prevent environmental release
Bioaccumulative Potential: Estimated low based on structure and log P values
Other Adverse Effects: Avoid unintentional release to waterways or ecological systems
Product: Collect solid residues in tightly closed, clearly labeled hazardous waste containers
Contaminated Packaging: Dispose of empty and contaminated containers according to regional requirements, do not reuse for other chemicals
Waste Treatment Methods: Follow local and national regulations for hazardous chemical disposal; incineration or chemical destruction in registered facilities recommended
