Chemical Name: Rosmarinic Acid
Common Name: Rosmarinic Acid
Purity: ≥ 98%
Impurities: None at trace level known to present physical or health risks
Other Components: Not present in hazardous concentrations
Inhalation: Move exposed person to fresh air. Seek medical attention if symptoms occur.
Skin Contact: Wash affected skin thoroughly with soap and water. Remove contaminated clothing.
Eye Contact: Rinse eyes carefully with plenty of water for several minutes. Remove contact lenses if present and easy to do.
Ingestion: Rinse mouth with water, do not induce vomiting. Seek medical attention if feeling unwell.
Additional Recommendations: Provide symptomatic and supportive care as required.
Suitable Extinguishing Media: Use water spray, dry chemical, foam, or carbon dioxide
Specific Hazards: Dust can form explosive mixtures with air if finely dispersed. Thermal decomposition generates irritating and toxic fumes, including carbon oxides.
Protective Equipment: Firefighters should use self-contained breathing apparatus and full protective clothing.
Special Precautions: Move containers from fire area if possible without risk. Avoid breathing vapors, dust, or combustion products.
Personal Precautions: Avoid inhalation of dust and skin contact. Wear appropriate personal protective equipment.
Environmental Precautions: Prevent further leakage or spillage if safe. Do not allow entry into drains, sewers, or waterways.
Methods for Containment and Cleaning: Pick up solids without creating dust. Sweep up and store in a suitable, closed container for disposal. Wash affected area with water and detergents.
Precautions for Safe Handling: Avoid contact with eyes, skin, and clothing. Use in well-ventilated areas. Minimize dust generation and accumulation.
Hygiene Measures: Handle in accordance with good industrial hygiene. Wash hands thoroughly after handling.
Safe Storage Conditions: Store in a tightly sealed container in a cool, dry, and well-ventilated place. Keep away from heat, sparks, open flame. Prevent humidity exposure.
Control Parameters: No specific occupational exposure limits established.
Engineering Controls: Use local exhaust ventilation where dust formation is possible. Handle in compliance with standard safety procedures.
Personal Protection: Wear protective gloves, safety goggles, and an approved dust mask. Use lab coat or protective clothing as needed.
Additional Recommendations: Eyewash stations and safety showers should be available at the workplace.
