Suitable Extinguishing Media: Dry chemical, CO2, foam, or water spray (water may be less effective for high-dust environments)
Unsuitable Extinguishing Media: Direct water jet in dusty setting may stir up powder rather than suppress fire
Specific Hazards: Combustion may release oxides of sulfur, carbon monoxide, carbon dioxide, and other hazardous vapors
Protective Equipment for Firefighters: Full protective equipment plus self-contained breathing apparatus (SCBA)
Special Procedures: Avoid inhalation of fumes, fight fire upwind, contain potential runoff to protect watercourses
Explosion Data: No known risk of dust explosion under typical laboratory or industrial use; avoid static discharge in bulk handling
Personal Precautions: Wear protective gloves, safety glasses or goggles, chemical-resistant clothing, avoid breathing dust, ventilate area
Environmental Precautions: Prevent uncontrolled entry to drains, sewers, or natural waterways, notify authorities if significant spill reaches the environment
Cleanup Methods: Collect solid using non-sparking tools, scoop into sealed, labeled waste containers, lightly dampen powder to limit airborne dust
Decontamination: Wash affected area with copious water and detergent, double-bag and appropriately label waste for disposal
Disposal of Debris: Dispose of contaminated materials according to local regulations, keep records of all disposal procedures
Handling: Use with adequate ventilation, avoid dust generation, never handle without protective gloves or eye protection, do not eat, drink or smoke in work area
Storage Conditions: Keep container tightly closed in a dry, well-ventilated place away from moisture, strong acids, and oxidizing agents, store below 30°C
Packaging Materials: Chemically resistant, sealed polypropylene or amber glass containers preferred for bulk or laboratory storage
Incompatibilities: Prolonged contact with strong acids, bases or oxidizers can degrade material or evolve hazardous vapors
Special Requirements: Careful labeling and segregation from food or other incompatible chemicals, inventory checks to avoid expired or degraded product
Occupational Exposure Limits: No precise regulatory limit for this material; minimize airborne concentrations as low as reasonably achievable
Engineering Controls: Laboratory fume hood or local exhaust ventilation (LEV), use enclosed systems for bulk handling
Personal Protective Equipment: Safety goggles or face shield, chemical-resistant gloves (nitrile, butyl rubber), lab coat or chemical apron, dust mask (P2 or N95) if dust risk present
Hygiene Measures: Wash hands prior to breaks, after use, and before eating; do not wear contaminated clothing outside of workspace
Environmental Controls: Secondary containment for bulk storage, spill trays to prevent release to drains, every spill contained and documented
Appearance: White to off-white crystalline powder
Odor: Faint, characteristic sulfonic or camphor-like odor
pH (1% solution): Strongly acidic (2 - 3)
Melting Point: 193–198°C
Boiling Point: Decomposes before boiling under atmospheric pressure
Solubility: Soluble in water, alcohols, and most polar solvents; low solubility in nonpolar organics
Vapor Pressure: Negligible at room temperature
Density: 1.5–1.7 g/cm3 (approximate for solid form)
Partition Coefficient: Not readily bioaccumulative; logP estimated below zero
Stability Indicators: Product stable under recommended storage parameters, sensitive to humid or acidic conditions
Chemical Stability: Stable under normal temperatures and pressures, dry and sealed storage extends shelf life
Reactivity: May react with strong oxidizers, reducing agents, or bases; avoid direct sunlight and heat sources
Hazardous Decomposition Products: Sulfur dioxide, carbon monoxide, carbon dioxide, camphor derivatives possible under fire conditions
Conditions to Avoid: Excess moisture, open flame, static discharge, incompatible chemicals
Polymerization: Does not polymerize spontaneously
Warning Signs: Pungent odor, discoloration, uncontrolled fume evolution signal product breakdown
Acute Toxicity: Oral LD50 in rodents estimated above 2,000 mg/kg, low single-dose toxicity
Skin and Eye Irritation: Substantial irritation with prolonged or repeated contact, eyes especially vulnerable to red, watery, painful response
Respiratory Effects: Inhalation of dust can trigger cough or shortness of breath, temporary irritation expected
Sensitization: Not a documented dermal sensitizer, but repeat exposure at high concentrations may cause local skin redness
Chronic Effects: Long-term studies limited, no evidence of carcinogenicity or mutagenicity, prudent practice limits unnecessary exposure
Other Health Effects: No reproductive or developmental toxicity data to date, treat as hazardous until more extensive studies reported
Ecotoxicity: Aqueous solutions may be harmful to aquatic invertebrates and algae; acidification of local water bodies disrupts ecosystem balance
Persistence and Degradability: Expected to degrade to sulfate and carboxylic acids over time via microbial action
Bioaccumulation: Low predicted potential, high solubility and negative logP mean little tendency to enter tissues
Mobility in Soil: Readily mobile in wet soils, strong acid may alter pH and affect soil microbiome
Other Adverse Effects: Avoid uncontrolled environmental release, even minor spills in surface water require prompt removal and remediation
Waste Disposal Methods: Treat as hazardous chemical waste, follow national, state, and local rules for incineration or chemical landfill
Container Disposal: Do not reuse packaging, triple-rinse containers before disposal, puncture to prevent reuse, clearly label as hazardous prior to final handling
Special Precautions: Only licensed hazardous waste carriers to transport, store in segregated area until final disposal, keep away from moisture
Regulatory Compliance: Document all quantities, transfer, and end-point waste figures to satisfy audit requirements and environmental reporting
UN Number: Not classified as dangerous goods under transport regulations (verify with current lists)
Proper Shipping Name: 2-Oxobornane-10-Sulphonic Acid or related descriptor
