A. Non- FOD Sensitive An area where the risk associated with a FO is negligible and no FOD control measures are needed.
B. FOD Awareness Area An area where the risk associated with a FO resulting in hardware damage/contamination is low.
C. FOD Control Area An area where the risk associated with a FO resulting in hardware damage/contamination is medium.
D. FOD Critical Area An area where the risk associated with a FO resulting in hardware damage/contamination is high.
Foreign Object (FO) and Foreign Object Damage (FOD) Definitions APPENDIX
A.1 Clean-As-You-Go - Defined by National Aerospace FOD Prevention, Inc. (NAFPI) as follows: “Clean the immediate area when work cannot continue. Clean the immediate area when debris has the potential to migrate to an out of sight or inaccessible area and give the appearance of poor workmanship. Clean the area prior to leaving it unattended, when work cannot continue, after work is completed or at the end of shift, whichever comes first. If you see something, drop something, see or hear something drop, pick it up.”
A.2 Consumables - For the purposes of this procedure, supplies provided to workers that are considered expendable; i.e., personal protective equipment, sealants, solvents, paint, brushes, applicators, sandpaper, rags, wipes, rivets, washers, fasteners, and other hardware.
A.3 Corrective Action Plan - Steps to be taken to prevent the root cause(s) of a FO and/or FOD incident from occurring again. The corrective action plan is not the direction necessary to remove the FO and restore the hardware.
A.4 Critical Foreign Object - FO debris that has a significant probability of causing system or component malfunction or deterioration if the item containing the FO debris is put into use.
A.5 Foreign Object Damage (FOD) - Any damage attributed to a FO that can be expressed in physical or economic terms, which may or may not degrade the product’s safety and/or performance characteristics.
A.6 Foreign Object (FO) - A substance, debris or article alien to a vehicle or system that would potentially cause damage.
A.7 Foreign Object Damage (FOD) Awareness Area - Any area designated as a low-risk area where quality sensitive products or hardware are in place and exposure to FOs would potentially cause a system or product malfunction or failure. Organizational Culture is focused on safety, reliability, and functionality by protecting all personnel, products and services from FO debris and damage.
A.8 Foreign Object Damage (FOD) Control Area - Any area identified as a medium-risk area where quality sensitive products or hardware are in place and exposure to FOs would potentially cause system or product damage, malfunction or failure. Stringent accountability measures shall be applied to control the risk of FOD in the area.
A.9 Foreign Object Damage (FOD) Critical Area - Any area identified as a high-risk area where quality sensitive products or hardware are in place and exposure to FOs would potentially cause system or product damage, malfunction or failure. Strict accountability measures shall be applied to control the risk of FOD in the area.
A.10 Foreign Object Damage (FOD) Sensitive Area – any area designated as either a FOD Awareness Area, a FOD Control Area, or a FOD Critical Area.
A.11 Foreign Object Damage (FOD) Sensitive Work – Work that is being conducted in a FOD sensitive area.
A.12 Foreign Object (FO) and Foreign Object Damage (FOD) Incident - An instance where a FO or FOD is found.
A.13 Housekeeping - Basic element of controlling a safe and effective work environment. Proper cleaning and organizing techniques are followed to ensure the prevention and elimination of FOs. Maintenance, manufacturing, testing and all other operational areas shall remain clean and organized with the ultimate goal to prevent debris from migrating into critical and complex hardware and facilities. The clean-as-you go work ethic is one of the most effective provisions for production, service, and preservation of products.
A.14 Non-FOD Sensitive - An area where the risk associated with a FO is negligible and no FOD control measures are needed.
A.15 Shadowbox - A tool box with specific, marked locations for each tool so that a missing tool will be readily noticeable.
A.16 Tether - A lanyard of sufficient strength (wire, rope, cable, etc.) attached to the tool/equipment and to the user or fixed secure object. The tether should be minimum length to preclude damage from tethered tool “free swing”.
A.17 Tote Tray - A device for storing/carrying/transporting tools or equipment in a secure manner to prevent inadvertent dropping: i.e., a tool holder, an apron with pocket rings to which tools can be secured. Tote trays with lids will have the lid secured to the tote tray body.Please View Our (FOD) Signs And Frames Page
IHST (International Helicopter Safety Team) Safety Survey
The IHST’s regional teams have analyzed over 1,000 helicopter accidents and determined that the following four areas offer the best opportunities to prevent helicopter accidents:
1. Safety Management Systems (SMS)
2. Structured programs for initial and recurrent training
3. Mission-specific systems and equipment, including:
- Health & usage monitoring systems (HUMS)
- Flight data monitoring (FDM) programs
- Night vision goggles
- Wire strike protection
This IHST global safety survey is intended to assess the progress toward full implementation of these practices within each industry sector in every region. While some of the recommended systems and equipment have mission specific application, the other recommendations for SMS, training and maintenance practices are universally applicable.
CONFIDENTIALITY: Your inputs will be kept confidential and will not be shared for advertising or marketing. The survey summary report will aggregate inputs by type of operation and use. Individual inputs will not be attributed to you or your company.
