Flue Space Labels for Warehouse Safety and Fire Code Compliance

Flue Space Labels for Warehouse Fire Safety Compliance

When it comes to warehouse safety, a few inches can mean the difference between a controlled emergency and a catastrophic event. That’s where flue space labels come in — small in size, massive in impact. At Pacific Barcode, we manufacture high-visibility, regulation-ready flue space labels that help your warehouse stay compliant, safe, and inspection-ready.

Whether you’re outfitting new racking or upgrading an existing system, our KEEP CLEAR flue space labels are the fast, reliable solution trusted by warehouse managers, safety officers, and installation contractors nationwide.

What Are Flue Space Labels?

Flue space labels are safety-critical markers placed on pallet rack beams to identify vertical gaps that must remain clear for fire safety. These gaps called “flue spaces” allow heat to rise rapidly in the event of a fire, helping sprinkler systems activate quickly and suppress flames effectively.

Warehouses without proper labeling risk non-compliance with High Pile Storage regulations and, more importantly, increase the danger to employees, assets, and operations.

Why Flue Space Labels Matter

The National Fire Protection Association (NFPA) defines flue space as the uninterrupted vertical space between pallet loads or between racking rows. This airflow is essential for fire suppression systems to work properly.

Here’s why our flue space KEEP CLEAR labels are mission-critical:

• Visual Compliance –  Bright, bold messaging (“KEEP CLEAR”) alerts staff to avoid placing pallets in restricted zones.
• Fast Identification –  Fire marshals and safety inspectors can instantly verify compliance during walkthroughs.
• Minimized Risk –  Clear flue spaces reduce the chance of delayed sprinkler activation in a fire event.
• Regulatory Peace of Mind –   Especially in high-regulation states like California, clear labeling helps ensure your warehouse meets local fire codes.

Designed for Real-World Warehouse Environments

Not all rack beams are created equal, and neither are your labels. At Pacific Barcode, we manufacture flue space labels that deliver visibility, durability, and flexibility in any environment.

• Standard Yellow Label with Red Text –  The industry default: ideal for contrast on orange, blue, green, red, or black beams.
• Red Label with Yellow Text – Perfect for light-colored beams (white, yellow, light gray), this label increases visibility where the standard option falls short.

Important: Some jurisdictions limit the use of red background labels. Consult your local Fire Authority or High Pile Storage consultant for guidance before choosing an alternative label color.

Built for Durability and Performance

Our flue space labels are engineered to last:

• Made from Gloss Poly with 1.1 mil PET lamination
• Built with All-Temp Adhesive for secure application in variable conditions
• Available in 3" or 6" widths with depths for standard beams or wire decking
• Highly visible, easy to apply, and compliant across a range of fire codes
