Firefighting Instructions: Move containers from fire area if safe, cool surfaces with water spray, avoid inhaling combustion gases
Personal Precautions: Wear gloves, use eye protection, avoid direct contact with molten wax
Environmental Precautions: Prevent large quantities from reaching drains or waterways by diking with inert material
Cleanup Methods: Allow to solidify, scrape or shovel into proper waste container
Spill Area Ventilation: Ensure adequate ventilation, especially during cleanup of hot wax
Disposal: Transfer waste to approved disposal facilities following local and national regulations
Handling Practices: Work with adequate ventilation, minimize dust and fumes, use heat sources with care to avoid splashing of molten wax
Hygienic Measures: Wash hands after use, avoid eating or smoking during handling
Storage Conditions: Store in cool, dry, well-ventilated space away from open flames, hot surfaces, and oxidizing substances
Packaging Materials: Suitable for steel, polyethylene, or fiber drums
Incompatibilities: Strong oxidizing agents; avoid contact with halogens
Exposure Limits: No established occupational exposure limit for microcrystalline wax dust or fumes
Engineering Controls: Install local exhaust ventilation if processing at high temperatures or in confined spaces
