Pressurized System

Pressurized System – Depressurize Before Service Sign

Clearly identify equipment containing hazardous internal pressure with the Pressurized System – Depressurize Before Service Sign. Its bold ANSI-style DANGER header, dual warning symbols, and highly visible message remind personnel to safely relieve system pressure before beginning maintenance, inspection, adjustment, disassembly, 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 white core beneath the red 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 near pneumatic equipment, hydraulic systems, pressure vessels, test stands, aircraft systems, maintenance areas, and other locations where retained pressure may present a serious hazard.

This sign supports—but does not replace—the facility’s required pressure-isolation, lockout, and verification procedures.

Manufactured in the USA with American material.
