The following recommendations on the removal of ash from communication systems are based on experience from the 1980 eruption Mt. St. Helens, Washington:

  • Blow out or vacuum out radio equipment and brush off.
  • Seal equipment that is not already watertight and keep moisture out of equipment.
  • Magnetic particles that stick to relay cores should be blown off.
  • Clean equipment daily and increase the use of filter paper.
