Emergency Contact: Refer to supplier or local emergency services for chemical spills or exposure incidents
Classification: Not classified as hazardous under GHS criteria
Signal Word: None required
Hazard Statements: Dust can cause irritation to eyes, skin, and respiratory system. Chronic exposure studies remain limited, but prolonged contact with dust may worsen respiratory discomfort or trigger skin dryness.
Precautionary Measures: Prevent formation of dust clouds, use basic hygiene measures, avoid inhalation and direct contact with skin, ensure workspaces with sufficient ventilation are utilized during handling
Substance: Tetradecanedioic Acid
Chemical Family: Aliphatic dicarboxylic acid
Concentration: >99% pure in most commercially available stock
Impurities: Minimal trace organics possible depending on supplier; not anticipated to significantly impact chemical behavior or health
Inhalation: Remove person from exposure to fresh air, support respiration if discomfort or respiratory distress continues, seek medical attention for persistent or severe irritation
Skin Contact: Wash exposed skin thoroughly with water and mild soap, remove contaminated clothing, seek medical evaluation if redness, irritation, or allergic reaction persists
Eye Contact: Rinse affected eye with plenty of clean water for at least 15 minutes, lifting eyelids to ensure complete washing, get prompt medical support if irritation continues
Ingestion: Rinse mouth thoroughly, never induce vomiting unless medical professionals direct, observe for gastrointestinal discomfort, seek medical attention if symptoms arise
Suitable Extinguishing Media: Use water spray, foam, dry chemical powder, or carbon dioxide for extinguishing, avoid direct water streams which may spread spilled powder or dust
Specific Hazards: Decomposition under fire conditions can generate carbon monoxide and carbon dioxide, possible formation of irritating fumes
Protective Equipment for Firefighters: Full protective gear, positive-pressure self-contained breathing apparatus recommended for firefighting in enclosed or heavily exposed settings
Precautions for Fire-Fighting: Minimize exposure to combustion fumes, local evacuation may be needed if large quantities burn
Personal Precautions: Avoid breathing dust, vent space as needed, wear skin, eye, and respiratory protection suited to site conditions
Cleanup Methods: Sweep up bulk material carefully to minimize airborne dust, collect spilled powder for disposal, wash contaminated surfaces with water and detergent to remove residues
Spill Response: Contain large spills using barriers or damp cloths to prevent scattering, restrict access to spill site until cleaned
Environmental Precautions: Prevent entry of spilled product into drains, soil, or surface water to protect local ecosystems
Safe Handling Guidelines: Minimize dust creation, practice good hygiene, avoid eating, drinking, or smoking near work areas, handle with adequate ventilation, use recommended PPE
Storage Requirements: Store in a tightly-closed container, place in a cool, dry, and well-ventilated location, avoid humidity to prevent clumping or solidification, segregate from strong oxidizing substances
Storage Stable Period: Typically stable under recommended conditions for multiple years, maintain rotated stock to ensure quality
Exposure Limits: No established occupational exposure limits, treat as a nuisance particulate by reference to general dust limits
Engineering Controls: Use local exhaust ventilation in processing areas, provide eyewash stations
Personal Protection Equipment: Safety goggles, gloves resistant to chemicals, disposable coveralls for large-scale handling, NIOSH-approved dust mask or respirator where powder becomes airborne or control measures are insufficient
Hygiene Practices: Remove contaminated clothing promptly, wash hands and exposed skin after handling
Appearance: White to off-white crystalline powder
Odor: Faint or nearly odorless
Molecular Weight: 258.36 grams/mole
Melting Point: 127–131°C
Boiling Point: Decomposes before boiling
Solubility: Slightly soluble in water; soluble in alcohol, acetone, and organic solvents
Vapor Pressure: Negligible at ambient temperatures
pH Value: Acidic in aqueous solution
Partition Coefficient: log Kow approximately 2.5 (estimated)
Flash Point: Not highly flammable, requires elevated temperatures to ignite dust
Chemical Stability: Stable under normal processing and storage, remains unchanged with low moisture and ambient temperatures
Incompatible Materials: Strong oxidizers, strong bases, moisture/humidity (if storage container is not adequately sealed)
Hazardous Decomposition: Heating above decomposition temperature may yield carbon oxides and acrid fumes
Polymerization: No known risk of hazardous polymerization in storage or use
Acute Toxicity: Low toxicity in mammals based on available animal testing data, not classified as sensitizer or major irritant
Routes of Exposure: Skin, eye, and inhalation; ingestion possible if food safety practices are ignored
Symptoms: Dust can cause physical irritation, redness of skin or eyes, dry cough, or throat scratchiness after prolonged exposure; minor gastrointestinal discomfort if large amounts are swallowed
Chronic Effects: No evidence of carcinogenicity, reproductive, or developmental toxicity in current research; long-term industrial experience indicates minimal health risk with good safety practices
Medical Conditions Aggravated: Individuals with pre-existing skin or respiratory conditions may be more sensitive to dust
Ecotoxicity: Product displays low acute toxicity to aquatic organisms under normal environmental concentrations, limited biodegradability in soil and water
Mobility: Limited potential for groundwater mobility due to low water solubility
Persistence and Degradability: Expected to persist in environment, gradual breakdown via microbial action over extended periods
Bioaccumulative Potential: Low to moderate potential based on estimated partition coefficient
Other Adverse Effects: Product release in large amounts could impact aquatic habitats through localized pH changes if not properly contained
Waste Management: Dispose of waste material under local, regional, and national regulations, avoid release to natural waters or open dumps
Incineration: Suitable for incineration in approved chemical waste facility if allowed by regulation
Landfill Disposal: Product can be buried in approved landfill following assessment by local authority
Recycling: Recover and recycle unused material where possible through returning to approved chemical processor, avoid contamination
UN Number: Not regulated under current UN, IMDG, or IATA transport codes
Transport Hazard Class: Non-hazardous for road, sea, or air transport
Packing Group: Not assigned
Special Precautions: Shield product from water and extreme temperatures during transit, ensure containers remain upright and well-sealed
U.S. Regulations: TSCA listed, not subject to major reporting under SARA, CERCLA, or RCRA; always check state requirements
