Open Engine FOD Prevention

Open Engine – FOD Prevention Required Sign

Help protect exposed engines and internal components from foreign object damage with the Open Engine – FOD Prevention Required Sign. Its bold ANSI-style CAUTION header, dual warning symbols, and highly visible message remind personnel to maintain strict FOD controls whenever an aircraft engine is open for inspection, assembly, maintenance, or repair.

Precision CNC-machined from premium ¼-inch HDPE ColorCore, every letter, symbol, and border is engraved to a depth of 0.098 inches, permanently exposing the contrasting black core beneath the yellow surface. Unlike printed graphics or applied vinyl, the recessed message will never peel, crack, or require repainting.

Available in two landscape sizes:

• 10"H × 14"W
• 14"H × 18"W

The nonporous HDPE construction resists moisture, common chemicals, corrosion, and everyday industrial wear. Pre-drilled corner mounting holes provide fast, secure installation in engine shops, aerospace production areas, maintenance hangars, inspection stations, test facilities, and other demanding environments.

Manufactured in the USA with American material.
