Corrosion PreventionCorrosion Prevention
Corrosion can be prevented by:Corrosion can be prevented by:
1. Education: Corrosion training
2. Performing requiredmaintenance inspections toidentify corrosion

nozzles (> 30 Degrees), 12 inches from surface3. Rinse at an angle between 15 and 30 degrees4. High pressure causes:
• Removes and damages paints and sealants• Forces water into seals• Structural damage to joints/honeycomb/thin
structures.• Water intrusion into electronic components
