Pallet Rack Spacing Requirements: Flue Space, Overhang, and Clearances
What the spacing around a pallet rack actually has to be — flue space, pallet overhang, aisle width, sprinkler clearance, and whether OSHA caps stack height.
Practical guidance on flue space, rack decking, protection, and warehouse safety compliance — written for the people who have to keep a facility inspection-ready.
What the spacing around a pallet rack actually has to be — flue space, pallet overhang, aisle width, sprinkler clearance, and whether OSHA caps stack height.
The warehouse safety rules that actually prevent injuries, the hazards behind each one, and a ready-to-use list of safety topics for your next toolbox talk.
A racking layout is set by the load, the truck, and the sprinkler system — in that order. The constraints worth fixing before anything gets bolted down.
The transverse flue is not just a gap in the rack — it is the path your sprinkler water takes, and often where the in-rack sprinklers themselves sit.
Flue space dividers hold the gap your sprinklers need when drivers cannot. What they do, and how a flue guard differs from a flue keeper.
Product loss has causes, and each one has a different fix. Sorted by what actually destroys the product — falls, forklifts, decking, pallets, and loading.
A pallet rack has three separate capacities, not one — beam, frame, and deck. How each is rated, how to read the plaque, and what quietly derates them.
OSHA has no pallet rack standard — which is exactly why racking gets cited. How enforcement actually works, and a checklist of what an inspector looks at.
