Which statement about explosion relief panels is FALSE?

  • A.They prevent an explosion from occurring
  • B.They limit the pressure rise within the structure
  • C.They direct the blast away from occupied areas
  • D.They are used alongside dust extraction

Answer: A

Correct answer: They prevent an explosion from occurring

Relief panels are a mitigation, not a prevention. They open at a set pressure so that the burning gases escape before the pressure can reach the strength of the casing, and they are oriented so that the blast goes somewhere safe. Prevention is the business of dust extraction and ignition control, and the two are used together.
