Eye Contact: Flush eyes with water for several minutes; check for contact lenses and remove if possible; consult a medical professional for persistent irritation
Ingestion: Rinse mouth; avoid inducing vomiting; seek medical help immediately if symptoms present
Most Important Symptoms: Eye redness, skin irritation, mild gastrointestinal discomfort, cough or throat irritation
Suitable Extinguishing Media: Dry chemical powder, foam, carbon dioxide, or water spray
Unsuitable Media: Avoid direct water stream; high pressure jet may cause dispersion of material
Specific Hazards: Burning releases oxides of carbon and nitrogen, potential for toxic smoke
Special Protective Equipment: Full protective gear, self-contained breathing apparatus
Advice for Firefighters: Contain runoff to prevent chemical entry into drains; focus on personal safety and safe evacuation first before attempting containment
Personal Precautions: Wear gloves, goggles, and suitable mask; ventilate area, avoid dust inhalation
Environmental Measures: Keep away from drains, soil, and waterways; block site of release as early as possible
Methods for Cleanup: Use inert absorbent (sand, earth); collect solid material in sealed container; wipe residues with wet cloth and dispose of according to regulations
Decontamination: Rinse affected area with plenty of water, ensure thorough removal of residues from hard surfaces
Handling Precautions: Use in well-ventilated areas; avoid contact with eyes, skin, and clothing; never eat or drink while using chemical
Storage Conditions: Keep in tightly closed container, stored away from direct sunlight, heat sources, and incompatible substances like strong oxidizers
Storage Temperature: Store at 2-8°C for stable shelf life
Incompatible Materials: Avoid acids, bases, oxidizing agents
Engineering Controls: Work under local exhaust ventilation or fume hood; use closed systems where possible
Personal Protection: Nitrile gloves, chemical splash goggles, lab coat, NIOSH-certified respirator in absence of adequate ventilation
Exposure Limits: No established occupational exposure limits; practice strict hygiene
Environmental Protection: Prevent large spills from entering drains or public waters; follow local environmental guidelines
Appearance: White to off-white crystalline powder
Odor: Faint, chemical odor
Melting Point: 55-60°C
Boiling Point: Not established; likely decomposes before boiling
Solubility: Soluble in ethanol and methanol; limited solubility in water
pH: Not measured in aqueous solution
Vapor Pressure: Data unavailable
Flash Point: Over 100°C
Density: Around 1.1 g/cm³ at ambient temperature
Stability: Stable under standard conditions when stored in original packaging
Possible Hazards: Avoid exposure to strong acids, bases, or oxidizers; risk of hazardous decomposition
Hazardous Reactions: No reports of dangerous polymerization under normal handling; reacts strongly with oxidizing materials
Decomposition Products: Carbon monoxide, carbon dioxide, nitrogen oxides under fire or thermal stress
Acute Toxicity: LD50 not established in animals; expected to have low acute toxicity based on available data for similar compounds
Skin Contact: Irritation possible, especially after prolonged or repeated exposure
Eye Contact: May cause noticeable irritation or redness
Inhalation: Exposure can produce mild upper respiratory symptoms if dust or vapors present
Chronic Effects: Not enough information on chronic effects; avoid repeated exposures to reduce risk
Sensitization: No known evidence of skin or respiratory sensitization from this compound
Carcinogenicity: Not listed as carcinogen by OSHA, IARC, NTP, or ACGIH
Mutagenicity / Teratogenicity: Insufficient data available for classification
Aquatic Toxicity: No direct studies, but limited persistence expected due to low usage volumes and degradation profile
Persistence and Degradability: Not persistent; expected to degrade through standard biological and chemical pathways
Bioaccumulation: Not expected to accumulate in living tissue or organisms
Mobility in Soil: Limited, though recommend limiting soil exposure
Other Adverse Effects: Discharge in large amounts into water or soil may still pose local risk to microorganisms; prevent uncontrolled release outside managed systems
Waste Disposal Methods: Collect all residues and processing wastes in sealed, labeled containers; send for incineration at a licensed chemical disposal facility
Disposal of Contaminated Packaging: Rinse empty containers with water and solvents, then send for disposal as hazardous waste
Legal Context: Follow all local, regional, and federal requirements for hazardous chemical waste; never pour into public sewer or open landfills
UN Number: Not assigned for small quantities of this material
Transport Hazard Class: Chemical not classified as dangerous by major transportation agencies
Packing Group: Not regulated for ground, air, or sea freight
Precautions: Ship in well-closed containers, avoid temperature extremes, shield from rough handling
Regulatory Status: Not listed under major controlled substance regulations
TSCA Status: Check with supplier regarding registration
REACH Status: Not registered under European chemical regulations
SARA Title III: Not listed as a hazardous substance
Labelling Requirements: Follow OSHA, GHS standards for workplace chemical labeling
Employer Requirements: Maintain access to updated safety data sheets and employee safety training as required by law
