How to Store Pallets Properly: Avoiding Damage and Waste
Proper pallet storage extends their lifespan, prevents safety hazards, and reduces replacement costs.
You invest in quality pallets. Don't let poor storage practices shorten their lifespan. How and where you store your pallets has a direct impact on their condition, safety, and useful life.
Indoor vs. Outdoor Storage
Indoor storage is ideal. Pallets stored inside are protected from rain, snow, UV radiation, and temperature extremes. They maintain consistent moisture content and avoid weather-related warping, mold, and deterioration.
Outdoor storage is often a practical necessity for businesses with limited indoor space. If you must store pallets outdoors:
Elevate stacks off bare ground using concrete blocks or sacrificial bottom pallets
Cover stacks with waterproof tarps, leaving air gaps for ventilation
Position stacks where drainage is good — never in standing water
Rotate your stock (first in, first out) to prevent long-term exposure
Stacking Guidelines
Empty pallets:
Stack no higher than 6 feet (approximately 15 pallets) for manual handling
Stack no higher than 15 feet when using forklifts, with stable base support
Keep stacks on level ground
Maintain clearance from walls for air circulation and fire access
Loaded pallets:
Follow your racking system's weight capacity ratings
Distribute weight evenly across the pallet
Use stretch wrap or banding to secure loads before stacking
Never stack loaded pallets more than two high without racking support
Moisture Management
Moisture is the number one enemy of wood pallets. It causes:
Mold and mildew growth
Wood swelling and warping
Accelerated nail corrosion
Weight gain (which affects shipping costs)
If pallets get wet, separate them and allow them to air dry before restacking. Don't wrap wet pallets in plastic — this traps moisture and accelerates mold growth.
Fire Safety
Dry wood pallets are highly flammable. Pallet fires are a significant risk in warehouse and yard environments.
Maintain at least 8 feet between pallet stacks and buildings
Keep stacks away from ignition sources (welding areas, electrical panels, etc.)
Have fire extinguishers accessible near pallet storage areas
Follow your local fire code for pallet storage limits and setbacks
Consider a sprinkler system in indoor pallet storage areas
Rotation and Inventory Management
First in, first out (FIFO) is the right approach for pallet storage. Pallets that sit for months deteriorate — even indoors. Moisture, insect activity, and simple gravity (the weight of pallets above compresses those below) all take their toll over time.
Mark incoming pallet shipments with a date and use the oldest stock first.
The Payoff
Good storage practices aren't glamorous, but they directly extend the life of your pallets, reduce replacement costs, prevent safety incidents, and keep your operation running smoothly. It's one of the easiest investments in operational efficiency you can make.
