Special Protective Equipment for Firefighters: Full protective clothing, self-contained breathing apparatus (SCBA)
Firefighting Instructions: Move containers away from fire if safe, use water spray to cool exposed containers, avoid inhalation of combustion products
Personal Precautions: Evacuate area, avoid dust/vapor formation, use personal protective equipment (gloves, goggles, particulate respirator), ventilate area
Environmental Precautions: Prevent further leakage or spillage if safe to do so, keep product out of sewers and watercourses
Methods for Cleaning Up: Use inert absorbent (sand, earth), sweep or collect spilled material into containers for disposal, wash area with plenty of water after removal, ensure all waste is handled in suitable containers labeled for chemical waste
Disposal: Dispose of in accordance with local, regional, and national regulations; do not allow to enter natural water bodies
Handling: Handle only in well-ventilated area, avoid breathing dust or vapors, avoid all unnecessary exposure, wear appropriate personal protective equipment, avoid contact with eyes, skin, and clothing, wash hands thoroughly after handling
Storage: Store in tightly closed containers, keep in cool, dry, well-ventilated area away from incompatible substances (strong oxidizers, strong acids), prevent moisture penetration, label containers clearly, store away from food or animal feed
Incompatibilities: Oxidizing agents, strong acids
Specific Storage Risks: Potential to absorb moisture and degrade over time, strict separation from incompatible materials
Occupational Exposure Limits: No specific exposure limits set for yttrium isooctanoate; use general particulate limits (OSHA PEL for particulates not otherwise regulated: 15 mg/m³ total dust; 5 mg/m³ respirable)
Engineering Controls: Use local exhaust ventilation or process enclosure to minimize airborne exposure
Personal Protective Equipment:
Respiratory Protection: Dust mask or respirator with particulate cartridge (N95 or better) for high concentrations
Eye Protection: Chemical safety goggles
Skin Protection: Chemical-resistant gloves (nitrile, PVC, neoprene), lab coat or apron
Other: Eyewash station and safety shower accessible in the immediate area of use
Appearance: Waxy solid or viscous amber liquid (form depends on precise formulation and temperature)
Odor: Mild, characteristic organic solvent odor
pH: Not applicable (insoluble in water)
Melting Point/Freezing Point: 45–60 °C (varies by grade and impurities)
Boiling Point: Decomposes before boiling
Flash Point: 145 °C (closed cup, approximate)

Chemical Stability: Stable under normal handling and storage conditions
Reactivity: Not reactive with most materials under ambient conditions
Conditions to Avoid: Elevated temperatures, open flames, extreme humidity, contact with incompatible materials
Incompatible Materials: Strong oxidizing agents, strong acids
Hazardous Decomposition Products: Yttrium oxide, carbon oxides, small amounts of hydrocarbon fragments in fire/decomposition
Hazardous Polymerization: Does not occur
Acute Toxicity: Expected to be of low toxicity, but limited toxicity data available for yttrium isooctanoate specifically
Routes of Exposure: Inhalation, skin and eye contact, ingestion
Symptoms: Irritation to eyes, skin, respiratory tract; possible abdominal pain if ingested
Chronic Effects: Repeated or prolonged exposure may cause dermatitis due to defatting of skin; possible respiratory irritation with chronic inhalation
Carcinogenic Categories: Not classified as a carcinogen by IARC, NTP, OSHA
Mutagenicity: No data available on mutagenic effects
Reproductive Toxicity: No data available for the compound; yttrium salts in general have not shown reproductive toxicity in humans at occupational levels
Other Information: General lack of epidemiological data for long-term human health impacts of yttrium organics
Ecotoxicity: Limited data on product; analogous yttrium compounds show moderate toxicity to aquatic organisms at high concentrations
Persistence and Degradability: Does not degrade readily; organic acid portion may eventually biodegrade, yttrium component persists
Bioaccumulative Potential: Expected to be low; yttrium does not significantly bioaccumulate in aquatic or terrestrial species
Mobility in Soil: Low mobility due to poor water solubility; tends to bind to soils and sediments
Other Adverse Effects: No known significant effects on ozone layer or global warming; prevent release to waterways to avoid accumulation in local sediments
Waste Treatment Methods: Collect and contain waste for disposal in accordance with local, state, and federal requirements
Unused Product: Dispose of through licensed chemical waste contractor; do not release into environment
