prevent defects on AC structures Flashcards
What are the 6 actions to protect AC surfaces
Fit blanks when A/C is outside
wear footwear that will not damage the coating
Avoid scratching/damaging the surface when handling GSE
Place removed access panels in safe position to avoid damage
Ensure drainage holes are free from obstructions to prevent trapping of water
Report graded surfaces, clean spilt chemicals
