Ash Removal and Clean-Up from Systems

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.
• Clean out microwave dishes, feed horns, and wave guides.
