Fire Protection

In-Rack Flue Space, Explained

Sprinklers can only stop a rack fire if water reaches it. Here's what transverse and longitudinal flue spaces actually are, what NFPA 13 asks for, and why they close up in a working warehouse.

How Often to Inspect Your Pallet Rack

There's no single federally mandated inspection interval for pallet rack. Here's the cadence most operators settle on, what to look at, and what to do the moment you find damage.

What is rack safety?

Rack safety is the practice of keeping industrial storage racking structurally sound and fire-code compliant, protecting uprights from forklift impact, keeping sprinkler flue spaces clear, anchoring and loading rack correctly, and repairing damage before it fails. We specialize in warehouse fire and life safety: engineered products, spec and compliance support, and audits that turn a code finding into a fix.

Frequently asked questions

Flue space is the clear gap between stored pallets and rows of rack that lets sprinkler water reach a fire burning deep inside the racking. NFPA 13 calls for nominal 6-inch transverse flue spaces — the gaps between loads and at the rack uprights. The longitudinal flue space, the gap between back-to-back rows, is a separate question that depends on your setup: it is generally not required in open double-row racks up to 25 ft, or where ESFR sprinklers are used, and is called for in taller double-row storage. Blocked flues are one of the most commonly cited fire-code issues in rack storage. You can screen your own setup for free with our Flue Space Calculator.
A common approach is routine visual checks by trained warehouse staff, a periodic inspection by a qualified expert (many operators schedule this at least once a year), and an immediate check after any forklift impact. Damaged uprights, loose anchors, bent beams, and missing safety clips should be tagged and addressed right away. If you would like an outside review, we offer warehouse and pallet-rack safety audits.
In many cases it can be repaired rather than replaced. We use engineered repair kits and build a repair plan around your specific rack, restoring the damaged section to its original load-bearing integrity, with a licensed professional engineer engaged when a job calls for a stamped design. This is usually faster and far less costly than tearing out and replacing whole rack bays after a forklift impact.
The three most relevant are NFPA 13 (sprinkler design and in-rack flue space for fire protection), OSHA 1910.176 (safe handling and storage of materials), and ANSI MH16.1 (the design, testing, and use standard for industrial steel storage racks). Our product specifications are mapped to these standards, and our team can help you match a fix to the specific code finding on your site.
Yes. Our warehouse and pallet-rack safety audits review your racking for damage, overloading, flue-space and anchoring issues, and code compliance, and give you a documented punch list of what to fix. It is the fastest way to turn an insurance or fire-marshal finding into a clear remediation plan. Contact us to schedule one.
We ship nationwide across the contiguous United States, and we coordinate installation through a network of vetted installation partners, contact us for Alaska, Hawaii, or international projects. To get a quote, send us your site details using the Get a Quote form or the quote request on any product page, and we will scope it and follow up.
