Relevant Exposure Limits: Not established for this specific compound; refer to general guidelines for chlorinated solvents and similar alcohols.
Inhalation: Move person to fresh air; support breathing as needed; call medical help for severe symptoms such as coughing, difficulty breathing, or dizziness.
Skin Contact: Remove contaminated clothing; wash thoroughly with soap and water. Do not use strong solvents or abrasives on skin. Seek medical advice if irritation or pain persists.
Eye Contact: Flush eyes gently with copious amounts of water for at least fifteen minutes, lifting eyelids often; obtain immediate medical attention for stinging, redness, or visual disturbances.
Ingestion: Rinse mouth with water; seek immediate medical advice. Do not induce vomiting unless directed by poison control.
Notes for Physicians: Symptomatic and supportive treatment; monitor for respiratory, hepatic, or renal complications; treat chemical pneumonitis and monitor airway.
Suitable Extinguishing Media: Dry chemical powder, carbon dioxide, alcohol-resistant foam. Avoid direct water streams on burning liquid.
Unsuitable Extinguishing Media: Strong water jets.
Fire Hazards: Flammable liquid and vapor. Vapors can form explosive mixtures with air in confined spaces. Hazardous decomposition products include hydrogen chloride, phosgene, and carbon monoxide under fire conditions.
Protective Equipment: Firefighters need self-contained breathing apparatus and full protective clothing.
Special Procedures: Move unaffected containers from fire area if this can be done safely. Use water spray to cool exposed containers. Avoid spreading fire-fighting water containing chemical into drains or waterways.
Personal Precautions: Evacuate area; ventilate space; avoid direct contact with spilled material. Wear chemical-resistant gloves, eye protection, impervious clothing, NIOSH/MSHA approved respirator if necessary.
Environmental Precautions: Prevent entry into sewers, surface water, or ground water. Notify local authorities if contamination occurs.
Methods for Clean Up: Absorb with inert material (sand, earth, vermiculite); collect in suitable sealed containers for disposal. Clean spill area thoroughly with detergent and water after removal.
Emergency Procedures: Eliminate all sources of ignition; use explosion-proof equipment in spill response; dispose of contaminated absorbents as hazardous waste as per local regulation.
Handling: Use in well-ventilated locations to minimize vapor buildup; ground and bond containers during liquid transfer to prevent static discharge. Wear proper PPE such as gloves and goggles. Do not eat, drink, or smoke while handling product. Wash hands and face after handling. Prevent skin and eye contact.
Storage: Store in cool, dry, well-ventilated area away from direct sunlight, heat sources, and ignition points. Keep container tightly closed. Use containers made of compatible material, such as glass, Teflon-lined steel. Segregate from oxidizers, acids, alkalis, and strong reducing agents; do not store with food, beverages, or animal feed. Clearly label all containers. Ensure suitable fire suppression measures are nearby. Regularly check for leaks or signs of degradation.
Occupational Exposure Limits: Currently, no TLV or PEL established; follow controls for structurally similar chlorinated alcohols if necessary.
Engineering Controls: Use local exhaust ventilation; general ventilation as backup. Eyewash stations and safety showers should be accessible. Enclosed systems or fume hoods preferred where possible.
Personal Protective Equipment: Protective gloves (nitrile, butyl rubber, PVC), safety goggles or face shield, flame-retardant lab coats or aprons. Respiratory protection with organic vapor cartridge if ventilation is inadequate.
Hygiene Measures: Wash skin thoroughly after handling; do not take contaminated clothing home. Launder contaminated clothing before reuse. Avoid inhaling vapors or mists. Remove and discard gloves and wash exposed skin before eating, drinking, or using restrooms.
