Firefighting Procedures: Remove containers from fire area if safe, keep windward, cool exposed tanks with water spray, avoid inhalation of smoke
Personal Precautions: Isolate spill area, ventilate area, avoid breathing vapors, wear suitable PPE, eliminate ignition sources
Environmental Precautions: Prevent entry into drains, sewers, basements, or confined areas
Methods for Clean-up: Contain spill, absorb with inert material such as sand or vermiculite, collect into suitable closed container for disposal
Handling: Use only in well-ventilated areas, avoid contact with skin, eyes, and clothing, ground all equipment, keep away from sparks, hot surfaces, or open flames
Storage: Store in tightly closed container, keep in a cool, dry, and well-ventilated space, segregate from oxidizers, acids, and reactive chemicals, store away from foodstuffs and incompatible substances
Exposure Limits: No established occupational exposure limit for cyclopentanemethanol, follow general guidelines for organic solvents
Engineering Controls: Provide local exhaust ventilation or general dilution ventilation as necessary, use explosion-proof equipment
Personal Protective Equipment: Chemical-resistant gloves, splash-proof goggles, lab coat, and approved respirator where vapor exposure is possible
Hygiene Measures: Wash hands before eating, smoking, or using restroom, remove contaminated clothing and wash before reuse
Appearance: Colorless liquid
Odor: Mild alcohol-like odor
Melting Point: -60°C
Boiling Point: 178-180°C
Flash Point: 74°C (closed cup)
Vapor Pressure: Low at 20°C, less than 1 mmHg
Solubility: Miscible with ethanol, limited solubility in water
Density: About 0.94 g/cm³ at 20°C
Viscosity: Moderate for alcohol of its size
pH: Not applicable (neutral organic liquid)
Partition Coefficient (n-octanol/water): Estimated moderate, data limited
Auto-Ignition Temperature: Not readily available, generally above flash point
Chemical Stability: Stable under normal temperatures and recommended storage conditions
Possibility of Hazardous Reactions: Can react with strong oxidizing agents, acids, or alkali metals
Conditions to Avoid: Heat, flame, strong oxidizers, sources of ignition
Hazardous Decomposition Products: Carbon monoxide, carbon dioxide, various hydrocarbons
Incompatibility: Strong acids, bases, and oxidizers cause reactions that may generate heat and hazardous products
Acute Toxicity: Data limited, considered slightly toxic by ingestion, inhalation, and skin contact
Skin Contact: May cause irritation, redness, and dryness
Eye Contact: Produces moderate irritation
Inhalation: Vapor may cause dizziness, headache, or respiratory tract irritation at high levels
Chronic Effects: Long-term exposure data lacking, avoid repeated skin or inhalation exposure
Carcinogenicity: Not classified as carcinogenic by IARC, NTP, or OSHA
Mutagenicity and Reproductive Toxicity: No reliable data available, recommended to minimize exposure
Ecotoxicity: Harmful to aquatic organisms in high concentrations, keep out of waterways
Persistence and Degradability: Readily biodegradable in water and soil under aerobic conditions
Bioaccumulative Potential: Moderate due to alcohol functionality, unlikely to bioaccumulate significantly
Mobility in Soil: Expected to be moderately mobile, may leach to groundwater
Other Adverse Effects: Prevent large-scale discharges to environment, report as required by local regulations
Waste Disposal: Do not pour into drains, minimize environmental release
Disposal Methods: Collect waste liquid in suitable containers, dispose according to local, regional, and national regulations
Contaminated Packaging: Decontaminate and recycle or dispose as hazardous chemical waste
Recommended Waste Code: Use code for waste organic solvents—consult local disposal authority
