Whichever way best facilitates fire fighting efforts

Stones

Pebbles

Gravel

Miscellaneous

Any walkway for storing debris temporarily

An inventory of tools before and after each job

An organized inspection and physical pickup of foreign objects

A place to store personal effects while working on the flight line

Primed and top coated due to its low resistance to corrosion

Heavily lubricated due primarily to its low resistance to corrosion

Free from lubricants due to its high resistance to corrosion

Bare due to primarily due to its high resistance to corrosion

Prevents it from being primed and top coated

Offers reduced resistance under all corrosive conditions

Provides increased resistance under mild corrosive conditions

Requires heavy lubrication to prevent further degradation of structural integrity

Highly resistant to corrosion

Easily corroded if moisture is absent

Easily corroded if moisture is present

Easily corroded in the presence of high-temperature exhaust

Small spots on the plated surface

A dull-gray product that can be wiped off

A bluish green coating on the surface of the product

A white yellow corrosion product appears on the exposed surfaces

Excessive use of lubricant attacking the structure

Dissimilar metal contact from the binding agents used

Entrance and entrapment of corrosive agents between the layers of metals

heat damage to the anti-corrosion coating caused by the welding process

Dissimilar metal contact between the steel pin and the aluminum hinge tangs

Residual oil quite often masks small quantities of water that set up hidden corrosion cells

Their constant actuation by maintenance personnel results in excessive wear of their finishes

Their protective finish is very often blistered by heat, blasted away by the high-velocity gases, and abraded by spent shell casings and solid particles from gun and rocket exhausts
