Which statement is false about solvent handling?

Which statement is false about solvent handling?

• A. Adequate ventilation should always be used when dealing with extraction solvents.
• B. The extraction solvent can be evaporated without ventilation.
• C. Any solvent handling requires no safety measures.
• D. Ventilation is optional for this procedure.

Answer: (B)

Handling solvents safely hinges on controlling vapors, since many extraction solvents are volatile, toxic, or flammable. Adequate ventilation removes vapors and reduces inhalation risk and the chance of ignition. Therefore, evaporating the extraction solvent without ventilation is not safe and is false. In reality, ventilation is a standard requirement, and solvent handling always benefits from safety measures, not optional or unnecessary ones. This is why the false statement is the one claiming you can evaporate without ventilation; the other points align with proper safety practice.
