Special Protective Equipment for Firefighters: Wear self-contained breathing apparatus (SCBA) and full protective gear; evacuate area of all unnecessary personnel
Fire and Explosion Risks: Product is not highly flammable; vapors may irritate respiratory tract in enclosed spaces
Thermal Decomposition: Produces toxic gases under intense heat
Accidental Release Measures
Personal Precautions: Use protective gloves, goggles, and clothing; ventilate area; eliminate ignition sources
Spill Methods: Absorb spilled material with inert absorbent (sand, vermiculite); collect and place into secure containers; wash spill site after cleanup directly into a chemical waste container
Environmental Precautions: Prevent entry into waterways, drains, and soil; notify authorities if a large spill threatens local water systems
Cleanup Techniques: Contain and collect in suitable non-sparking containers for disposal; decontaminate spill area thoroughly after collection
Handling and Storage
Handling: Avoid all unnecessary contact with skin, eyes, and clothing; work in ventilated areas; wash hands thoroughly before eating, drinking, or smoking after handling
Storage Conditions: Store in tightly sealed containers in a cool, well-ventilated, dry area, away from strong oxidizers, acids, and bases; keep container clearly labeled
Safe Work Practices: Do not eat, drink, or smoke while using this product; keep storage areas clean and organized; ensure containers are upright to prevent leaks
Exposure Controls and Personal Protection
Engineering Controls: Use local exhaust ventilation or chemical fume hood to minimize exposure
Personal Protective Equipment: Protective nitrile or neoprene gloves, safety goggles, lab coat or apron, closed-toed shoes
Respiratory Protection: Respirator recommended if ventilation is inadequate or if aerosolization of the compound may occur
Hygiene Measures: Wash thoroughly after handling; do not reuse contaminated protective equipment; maintain clean workspace
Exposure Limits: No specific limits yet established for this compound; minimize exposure as a conservative approach

Incompatibilities: Avoid exposure to strong oxidizers, strong bases, acids, and strong reducing agents
Conditions to Avoid: High temperatures, open flames, and direct sunlight, as these may produce hazardous decomposition products
Decomposition Products: Hydrogen chloride, phosgene, carbon monoxide, and carbon dioxide can be released in a fire
Toxicological Information
Acute Toxicity: Oral LD50 in rats: data not widely available; considered low-moderate toxicity based on related chemicals
Skin Contact: Causes mild to moderate irritation, especially on prolonged exposure
Eye Contact: Causes irritation, may result in redness and discomfort
Inhalation: Irritation of respiratory tract symptoms, especially if aerosolized or inhalation of vapors occurs
Chronic Exposure: Prolonged occupational exposure may cause dermatitis, potential sensitization in rare cases
Carcinogenicity: Not classified as carcinogenic by major agencies (IARC, NTP, OSHA)
Mutagenicity: No evidence from testing on this chemical or closely related substances
Other health hazards: Risk of aspiration and lung damage if swallowed and subsequently vomited
Ecological Information
Toxicity to Aquatic Life: Considered harmful to aquatic organisms based on chemical structure and related substances
Persistence and Degradability: Not readily biodegradable, may persist and accumulate in the environment
Bioaccumulation: High potential due to long hydrocarbon chain
Mobility in Soil: Low water solubility and high hydrophobicity means it may adsorb to soil and sediments
Other Adverse Effects: May cause long-term adverse effects in the aquatic environment; should be prevented from environmental release whenever possible
Disposal Considerations
Disposal Methods: Place in appropriate chemical waste container; send to licensed chemical disposal facility; do not pour down drains or sewers
