PICRIC ACID (SOAKED IN WATER)

Picric Acid (soaked in water) is a chemical compound primarily used in laboratory and industrial settings. This form of picric acid, stabilized by water, mitigates its explosive nature, making it safer to handle. Known for its strong acidic properties, it plays a critical role in explosives testing, chemical analysis, and histology. Picric Acid is a yellow crystalline substance that dissolves in water to produce a bright yellow solution.

Safety and Handling

Safety Precautions

Picric Acid is potentially hazardous, especially in its dry form, as it is highly explosive. Proper handling and storage are crucial.

• Stabilization: Always keep Picric Acid wet (≥30% water) to minimize the risk of explosion.
• Personal Protective Equipment (PPE): Use gloves, goggles, and protective clothing.
• Work Environment: Handle in a well-ventilated area with appropriate fire suppression systems.
• Avoid Contamination: Keep the acid away from metals, organic materials, and alkalis to prevent reactive incidents.

First Aid Measures

• Skin Contact: Wash the affected area thoroughly with soap and water. Seek medical attention for irritation.
• Eye Contact: Flush eyes with water for at least 15 minutes. Consult a physician if symptoms persist.
• Inhalation: Move the individual to fresh air. If respiratory distress occurs, seek immediate medical assistance.
• Ingestion: Do not induce vomiting. Rinse the mouth with water and seek emergency medical help.

Storage Guidelines

• Store Picric Acid in a cool, dry, and well-ventilated area.
• Always maintain the acid in its wet state to prevent crystallization.
• Use non-metallic, tightly sealed containers.
• Label containers clearly to prevent accidental misuse.

Environmental Considerations

Dispose of Picric Acid according to local hazardous waste disposal regulations. Prevent contamination of soil and water sources to protect the environment.
