Relevant Impurities: No hazardous impurities over regulatory thresholds
General Advice: Move to fresh air, seek medical attention if symptoms persist or worsen
Inhalation: Remove from exposure, provide fresh air, consult medical help if breathing difficulty develops
Eye Contact: Rinse cautiously with water for at least fifteen minutes, remove contact lenses if present and easy to do, call a physician if irritation remains
Skin Contact: Wash thoroughly with soap and water, remove contaminated clothing, seek healthcare advice if irritation or discomfort continues
Ingestion: Rinse mouth, drink water, consult poison control or physician in case of discomfort or large amount intake; do not induce vomiting unless directed by a medical professional
Suitable Extinguishing Media: Water spray, dry chemical, foam, carbon dioxide
Unsuitable Extinguishing Media: High-pressure water streams can spread product dust
Special Hazards: Decomposition can produce irritating fumes (carbon oxides), dust may form explosive mixtures with air under certain conditions
Protective Equipment for Firefighters: Full protective gear including self-contained breathing apparatus, avoid inhalation of combustion products
Further Information: Move containers from fire area if safe to do so, prevent run-off from entering drains or waterways
Personal Precautions: Wear protective equipment (eye protection, gloves, suitable clothing), avoid dust formation, ensure adequate ventilation
Environmental Precautions: Prevent product from entering drains, watercourses, or soil
Methods for Containment and Cleaning Up: Sweep or vacuum up spill, avoid dry sweeping if dust generation possible, transfer to suitable container for disposal, use damp cloth to finish clean-up for fine residues
Reference to Other Sections: Consult Sections 8 for personal protection and 13 for disposal considerations
Safe Handling: Minimize dust generation and accumulation, wash hands after use, avoid inhaling dust, use in well-ventilated settings, do not eat or smoke while handling
Safe Storage: Store in a tightly closed container, keep in a cool, dry, well-ventilated place, protect from moisture and incompatible substances, store away from oxidizing agents and bases, label containers appropriately
Exposure Limits: No established occupational exposure limits specific to DL-Malic Acid; handle as a nuisance dust
Engineering Controls: Use local exhaust ventilation or general room ventilation to keep airborne concentrations low
Personal Protective Equipment: Eyes: Safety goggles or face shield; Skin: Protective gloves (nitrile or latex), lab coat; Respiratory: Dust mask or respirator if exposure to large amounts of dust; Hygiene Measures: Wash hands after handling, do not eat, drink or smoke in work area, remove contaminated clothing and wash before reuse
