Hazardous Components: Naphthenic acids (Variable, 35–60%), Iron salts (10–15%), Hydrocarbon carrier (typically 30–60%), Additives and surfactants (trace amounts)
Impurities: May contain trace metals or sulfur compounds depending on crude source
Inhalation: Move person to fresh air. Support breathing as needed. Seek medical attention if symptoms persist or worsen.
Skin Contact: Wash exposed area thoroughly with soap and water. Remove contaminated clothing and wash before reuse. Seek medical advice if irritation continues.
Eye Contact: Rinse immediately with plenty of water for no less than 15 minutes. Remove contact lenses if present and easy to do. Consult an ophthalmologist if irritation continues.
Ingestion: Rinse mouth. Do not induce vomiting unless directed by medical personnel. Get medical help promptly.
Most Important Symptoms/Effects: Risk of nausea, coughing, dizziness, headache, or respiratory irritation after significant exposure. Possible liver or kidney effects after large or prolonged exposure.
Immediate Medical Attention: Seek urgent care in case of breathing difficulties or persistent eye pain.
Suitable Extinguishing Agents: Dry chemical powder, carbon dioxide, foam, water spray (do not use straight streams)
Hazards from Combustion: Produces carbon oxides, iron oxides, irritating fumes, and possibly sulfur oxides
Advice for Fire Fighters: Wear full protective gear and a self-contained breathing apparatus for enclosed or significant fires. Prevent runoff from entering drains or waterways.
Specific Hazards: Containers may rupture under intense heat. Some decomposition products may depress CNS function if inhaled.
Special Protective Equipment: Chemical resistant suit, heat-resistant gloves, eye protection with side shields, positive pressure respiratory protection
Personal Precautions: Keep unauthorized persons away from spill site. Use chemical-resistant gloves, splash-proof goggles, and respirators in poorly ventilated environments.
Environmental Precautions: Prevent material from entering soil, waterways, drains, and sewers. Alert local authorities if significant environmental release occurs.
Methods for Clean-Up: Absorb with inert material such as sand, earth, or vermiculite. Collect contaminated material in sealed containers for disposal. Wash spill area thoroughly after initial cleanup.
Secondary Prevention: Ventilate area well and wash hands thoroughly before eating, drinking, or smoking.
Special Procedures: Contain runoff and collect for disposal according to local, regional, and national regulations.
Safe Handling: Use only in well-ventilated areas or controlled workspaces. Wear appropriate PPE including gloves, eye protection, and protective clothing. Avoid direct contact with skin, eyes, and clothing. Do not inhale vapors or mists. Wash thoroughly after handling.
Storage Requirements: Store in tightly closed original containers in a cool, dry, well-ventilated area, away from heat, sparks, open flames, strong acids, and oxidizers. Protect against physical damage.
Incompatible Materials: Strong oxidizing agents, mineral acids, and alkalis
Special Storage Considerations: Keep away from food, drink, and animal feed. Store at temperatures between 0–35°C. Clearly label storage area and restrict access.
Occupational Exposure Limits: No specific OSHA or ACGIH exposure limits for this compound. Recommend minimizing exposure as a precaution.
Engineering Controls: Provide local exhaust or general room ventilation to maintain airborne levels below recommended limits.
Personal Protective Equipment: Chemical-resistant gloves such as nitrile, neoprene, or PVC; safety goggles or face shields for splash protection; chemical apron or lab coat; NIOSH-approved respirator for high vapor or mist conditions
Hygiene Measures: Wash hands, arms, and face after handling. Remove contaminated clothing and wash before reuse.
Environmental Controls: Prevent release to the environment, especially discharges to waterways or sewers.

Acute Toxicity: May be toxic by ingestion or inhalation; causes irritation to skin and eyes
Symptoms: Headache, dizziness, nausea, skin redness or rash, eye stinging or watering, coughing, and throat irritation
Chronic Effects: Prolonged or repeated exposure may cause dermatitis, liver or kidney damage
Carcinogenicity: Not classified as carcinogenic to humans based on available data
Mutagenicity / Teratogenicity: No reliable data available
LD50 (oral, rat): >2,000 mg/kg (estimated, solvent dependent)
Toxicity to Aquatic Organisms: Harmful to aquatic life, particularly fish and invertebrates. May cause long-term adverse effects in the aquatic environment.
Persistence and Degradability: Naphthenates may degrade slowly in soil and water. Hydrocarbon carrier fraction degrades more slowly.
Bioaccumulation: May bioaccumulate in organisms, especially aquatic species.
Mobility in Soil: Tends to bind to soil and sediments, mobility generally low.
Other Adverse Effects: Runoff can impact aquatic systems if released in large quantities. Not expected to contribute to ozone depletion.
Waste Disposal: Handle as hazardous waste. Incinerate under controlled conditions or dispose of in accordance with local, regional, and national regulations.
Container Disposal: Triple-rinse old containers and offer for reconditioning or recycling if available. Do not reuse for food or beverage storage.
Special Precautions: Avoid spill and contamination of water sources.
Disposal Methods: Consult with licensed waste disposal contractor or site. Do not pour product or residues into drains, soil, or any unapproved areas.
