Inhalation: Move person to fresh air; rinse mouth and throat with water; seek medical advice if symptoms persist
Skin Contact: Wash with soap and water; remove contaminated clothing; seek medical attention if irritation develops
Eye Contact: Flush eyes with running water for at least 15 minutes; remove contact lenses; medical attention is recommended for persistent irritation
Ingestion: Rinse mouth thoroughly; drink water to dilute; do not induce vomiting unless directed by medical personnel; seek medical help for large amounts or if symptoms develop
Symptoms Requiring Immediate Attention: Persistent irritation, trouble breathing, or allergic reactions
Suitable Extinguishing Media: Foam, dry chemical, CO2, water spray
Unsuitable Media: Direct water streams may spread molten product
Fire Hazards: Produces acrid fumes, carbon oxides; dust-air mixtures can ignite if dispersed
Protective Equipment: Firefighters wear standard gear and self-contained breathing apparatus
Special Considerations: Dike runoff for proper disposal; containers may melt and release product if exposed to flame
Combustion Products: Carbon dioxide, carbon monoxide, small amounts of irritant organic compounds
Personal Precautions: Use gloves, eye protection, dust mask
Environmental Precautions: Prevent large spill runoff into sewers or waterways
Cleanup Procedures: Sweep or shovel material, avoid raising dust, collect in suitable labeled containers for disposal; scrub residues with detergent and water
Spill Sizes: For small spills, sweep up; for large spills, isolate area and contact safety personnel
Disposal After Cleanup: Consult local regulations for approved landfill or incineration
Other Precautions: Wash surfaces and ventilate area
Handling Precautions: Keep containers tightly closed; minimize dust formation; avoid breathing dust or vapor; handle with clean gloves
Storage Requirements: Store in cool, dry space; avoid direct sunlight; keep away from strong oxidizers; use containers made from materials resistant to fatty acids
Additional Measures: Label containers properly; provide spill containment; control sources of ignition where dust may form
Incompatible Materials: Strong acids, alkalis, oxidizing agents
Engineering Controls: Local exhaust ventilation for dust control; general ventilation preferred in bulk use areas
Exposure Limits: No occupational exposure limits for lauric acid published by OSHA, ACGIH
Personal Protective Equipment: Wear chemical-resistant gloves (nitrile or neoprene preferred), safety glasses or goggles, dust mask or respirator in high-dust environments, protective clothing as needed
