In work handling organic solvents, what is the main purpose of grounding containers and piping?

  1. ATo cool the solvent
  2. BTo prevent ignition by static discharge
  3. CTo preserve the solvent's color
Show answer and explanation

Answer: B. To prevent ignition by static discharge

Transferring organic solvents or flowing them through piping generates static electricity by friction. If static builds up and discharges, the spark may ignite solvent vapor. Grounding containers and piping lets the static escape, preventing this.
