A well-established plan for material handling and parts protection can eliminate many potential FOD hazards. First, identify the specifics such as sensitive parts, assemblies, surfaces, areas, etc. Then, sequence events for packaging, handling, shipping and storage, and finally, evaluate cleanliness and care requirements.
Control Techniques:
1. Al] employees should be trained to assure compliance with packaging, handling, shipping and storage requirements.
2. Materials and accessories used in the packaging, handling, shipping and storage which have intimate contact with the part or assembly should be clean and free of contamination.
3. Parts and assemblies shall be packaged in a manner that will preclude any chance of one item making contact with another during normal handling operations.
4. Protective and packaging materials shall be chosen based on their ability to adequately resist penetration by tearing, parting or piercing from forces either external or internal during normal handling operations.
5. Specific instructions for packaging/unpackaging/handling shall be established
6. Protective devices (edge protectors, cam, plugs, covers, filters, rub strips) shall be clean and MUST BE secured to prevent accidental damage. Once installed, unauthorized removal of protective devices is prohibited. Removal should be authorized only through assembly or maintenance planning paperwork.
7. Particular care must be taken with items that are subject to damage by Electrostatic Discharge (ESD). ESD can be considered FOD damage. The use of proper handling, grounding controls and devices and proper ESD protective packaging.
8. Consideration should be given to the visibility/detection of material used for protection so that the material in itself doesn't become FOD. Consideration should include:
A. Color of packaging or protective devices so they don't appear to be a part of what they are protecting.
B. Streamers for removal for critical items.
Material Characteristics:
1. Materials should be compatible with the environmental and physical stresses expected to be encountered during product service.
2. Static sensitive devices shall be properly protected to avoid damage. Materials that are used to protect electro-explosive devices and sensitive electronic components should be kept clean, covered, and stored away from ordinary nonstatic safe materials.
Condition:
Visually inspect all packaging, handling, shipping and storage containers for the following:
1. Nicks, dents, holes, abrasions, scratches, burns, etc., which may be detrimental to the function and integrity of the part or assembly.
2. Grease, preservatives, corrosion products, weld slag, shop and other dirt, and other materials foreign to the item.
3. FOD also shows up as dirt, grime, debris, metal shavings or filings
4. When you come across a container that needs to be cleaned, Identify it as “ Need to be Cleaned” or clean it immediately
