Always wear appropriate personal protective equipment (PPE), including safety goggles, gloves resistant to nitric acid and barium compounds, and a lab coat. Nitric acid is corrosive and barium carbonate is toxic; protect your skin and eyes.
Work in a well-ventilated area or under a fume hood. Nitric acid fumes are harmful. Adequate ventilation minimizes inhalation risks.
Handle nitric acid carefully, avoiding spills. Use a dedicated container and transfer carefully with appropriate pipettes or dispensing equipment to avoid splashes. Neutralize any spills immediately with sodium bicarbonate solution. Use caution and care in handling.
Store nitric acid and barium carbonate separately in compatible, clearly labeled containers. Ensure proper storage conditions are met. Never mix them until absolutely necessary and always under a fume hood.
Dispose of waste materials according to local regulations. Both nitric acid and barium carbonate require special waste disposal procedures. Consult your institution’s safety guidelines.
| Nitric Acid | Corrosive, oxidizing | Wear gloves, goggles, lab coat; work under fume hood; neutralize spills |
| Barium Carbonate | Toxic | Avoid inhalation and ingestion; wear gloves; dispose of waste properly |
In case of skin or eye contact with nitric acid, immediately flush with copious amounts of water for at least 15 minutes and seek medical attention. For ingestion, contact a medical professional immediately. Barium carbonate ingestion requires prompt medical attention. Follow all institutional safety protocols and consult your safety data sheets (SDS) for detailed information on handling and emergency procedures.
