Quick answer: FOD does not distribute randomly across a facility — it concentrates in predictable locations based on where debris is generated (sources), where it travels (paths), and where it accumulates (sinks). A hotspot map records these repeat-location patterns and assigns controls to each one. It is Form 04 in the Complete FOD Prevention Program Guide toolkit, referenced in Section 18.

Sources: Where Debris Enters

Tool staging and use areas, maintenance and assembly workstations, packaging and unpacking zones, personnel entry points, vehicle entry points, and facility deterioration points.

Paths: How Debris Travels

Foot traffic routes, vehicle routes (tire transport, aerodynamic redistribution), air currents and HVAC-driven movement, water flow toward drains, and gravity from elevated work.

Sinks: Where Debris Ends Up

Against walls, curbs, and barriers; in corners and alcoves; under equipment and furniture; in drains and floor joints; and in low-traffic zones next to high-traffic routes.

Universal Hotspot List

Each hotspot is both an inspection priority and a container placement candidate.

Hotspot Why Debris Concentrates Inspection Technique
Tool staging and shadow board areas Tools handled repeatedly; dropped items; packaging from replacement tools Inspect the floor in a 6-foot radius around every tool board; look under the board
Aircraft and equipment parking spots Debris falls during maintenance; migrates under tires and into wheel chock areas Inspect the full parking footprint plus a 10-foot perimeter, especially under engines and landing gear
Work benches and assembly stations Small items fall or are set aside and forgotten; consumables accumulate Inspect the bench, the floor under and around it, and adjacent horizontal surfaces
Doors, thresholds, and transitions Debris travels with traffic; transition strips trap items Inspect both sides of every door; check the threshold strip for lodged items
Pavement joints and cracks Debris falls into joints and becomes trapped below the visual surface Look along joints, not across them; shine a flashlight at an angle

Frequently Asked Questions

What is the difference between a hotspot and a general finding?
A hotspot is a location that produces repeat findings over time, identified through pattern analysis of the findings log. A general finding is a single instance of debris that may or may not turn into a recognized pattern.
How is a hotspot map used during a walk?
Walk leaders pause for deliberate, closer inspection at each mapped hotspot during Step 8 of the walkdown execution procedure — edges, drains, joints, under equipment, tool staging, and overhead structures.
What should be recorded on the worksheet?
Each hotspot’s location, why debris concentrates there (source, path, or sink mechanism), the assigned control, and inspection frequency.
