Five Tips for Stacking Pallets Properly

Do your employees know how to stack a pallet safely?  Do you need help with forklift stacking and other cargo organization techniques?, the leader in online forklift training and OSHA compliance, put together this forklift stacking guide to increase safety and help you avoid accidents on the job.

Proper pallet stacking provides two very important outcomes in a warehouse. One is improving safety. The other is cutting costs and improving productivity.  Stacking pallets correctly helps prevent accidents that can occur when using a pallet jack, forklift, hand pallet pump, or other lifting machine. Combining safe pallet stacking and forklift stacking with advanced storage and handling methods – such as double-stacked pallets – helps trim costs by working more efficiently.

 The key to achieving these outcomes is knowing how to stack a pallet safely. That starts with thorough training in all aspects of forklift and other lift machine handling. And there’s no better way to acquire that training than at

Fast and affordable, our online training courses meet all OSHA standards. Our training, which acts as an ultimate pallet stacking guide of sorts, will teach you how to:

Safely use forklifts in all types of job environments

Operate forklifts during heavy volume and high-traffic work conditions

Know when and how to use double-stacked pallets

Proper Pallet Stacking Techniques – Pallet Stacking Guide and Step-by-Step Tutorial

Falling objects, loads stacked the wrong way, and unsafe use of forklifts can lead to accidents and injuries.  You can reduce these risks by teaching people proper pallet stacking, starting with these tips.

How to Stack a Pallet  Safely

Stacking pallets of the same size will produce an evenly distributed stack. This will reduce the chances of the stack shifting or falling. It also reduces the amount of empty space between stacks, making it the most efficient way of stacking.

When working with different-size pallets, always place the largest item on the bottom row. This also applies to the products on the pallet. Stacking items of uniform size and shape next to each other will prevent products from shifting and falling. When dealing with double-stacked pallets, be sure to use proper lifting aids. These include bars, stabilizers, and other tools that enhance lift safety.

Another safety tip: make sure your double-stacked pallets are always the same width. Accidents are more likely to happen if your pallet configuration varies with any given load.

1. Do Not Exceed Height Limitations

The first rule of proper pallet stacking is never stack them too high. Doing so greatly increases the risk of the top pallets falling over. It also increases the risk of injuring or killing workers on the ground. Know how much space you have on the lower and middle racks. Then make sure not to stack pallets too high on the top rack. Over-stacking pallets can cause goods to fall and suffer damage when loading or unloading the pallet.

2. Do Not Exceed Weight Limitations of Your Forklift or Pallet Jack

Pallet stacking often involves fairly heavy items. So make sure the operator knows the maximum weight the pallet jack or forklift can hold. Lifting more than the forklift is designed to hold is a major safety hazard. If the forklift topples over, it can injure the operator or crush workers nearby.

3. Put the Heaviest Items on the Bottom

The proper safety technique is to put the heaviest item(s) on the bottom of the pallet. Then put the heaviest pallets on the bottom of the stack. This will create a stable base with a lower center of gravity. When hauling double-stacked pallets, make sure the load doesn’t exceed the forklift’s max weight limit. An overloaded forklift can cause an accident before the pallets are even stacked.

4. Stack Pallets Evenly

Warehouse safety requires stacking pallets evenly. This means no edges poking out the sides. Uneven stacking causes an unstable pallet stack. This increases the chances of the stack falling from the forklift or rack during transportation. Stacking pallets evenly also ensures the weight is properly distributed to avoid shifting. Objects sticking out from the edge of the stack also present a safety problem.

Also, keep an eye out for any loose parts that could be snagged by a machine or worker during loading and unloading.

5. Never Reuse Damaged Pallets

It can be tempting to reuse damaged pallets to save a few dollars here and there.

However, it’s never safe to reuse damaged pallets. They aren’t as stable and durable as undamaged pallets, which can lead to stack tip-overs.  Any part of the pallet that contains splintered areas or protruding nails and fasteners can injure workers. When in doubt, do the right thing and buy replacement pallets rather than using damaged ones.

Forklift drivers should understand that double-stacked pallets create unique safety hazards, and should always be handled with extra caution. Using plastic wrapping and banding can lower the risk of accidents by keeping pallets secure. If you’re unsure about handling a double-stacked pallet, consult with your job site manager or safety expert.


OSHA Pallet Stacking and Lift Operation Recommendations

According to OSHA, “cargo, pallets and other material stored in tiers shall be stacked in such a manner as to provide stability against sliding and collapse.” The instructions listed above are the most critical for ensuring the stability of stacked pallets and preventing accidents.

Workers that use forklifts, pallet jacks, and pallet pumps to move and stack pallets must know how to correctly stack pallets. They also need to know how to use the equipment properly. OSHA says that proper pallet stacking requires workers to be aware of both manual handling concerns and equipment handling techniques. Workers should always move and stack pallets according to their weight, size, and shape to avoid overloading the equipment.

OSHA tips for safe pallet stacking and driving with a load include:

✓ Center the load on the forks as close to the forklift mast as possible. This will help prevent tip-overs of the equipment or load.

✓ Never overload a lift truck past its rated capacity.

✓ Do not put extra weight on the rear of a counterbalanced forklift to allow an overload.

✓ Adjust the load to the lowest position when traveling.

✓ When possible, correctly pile and cross-tier all stacked loads.

✓ Ensure workers have the proper personal protective gear. This includes gloves, hats, goggles, and steel-toe boots.

OSHA safety tips for accessing stored and stacked pallets and other loads include:

✓ Keep storage areas free of materials that can cause tripping hazards or fires.

✓ When storing goods inside buildings under construction, place pallets and materials at least six feet away from hoist-ways and floor openings. Place them at least 10 feet away from exterior walls

✓ Separate non-compatible goods.

How High Can You Stack Pallets in a Warehouse?

Stacking pallets high can be useful – up to a point. It frees up more stacking space, which allows you to store more products or materials. It also reduces tripping and collision hazards from your warehouse floor. However, go too high and your pallet stacking won’t comply with OSHA standards.

Exceeding the recommended height limit makes pallet stacks more prone to tip-over and collapsing. However, height limits can vary according to whether the pallets are full or empty. They also depend on the stacking technique used. The materials being stacked can also affect the height limit because some have specific requirements.

The National Fire Protection Agency recommends the following safety tips:

✓ When storing pallets inside, have no more than four stacks, and stack no higher than six

✓ Do not store pallets within 25 feet of other materials.

✓ Install special sprinkler systems when using plastic pallets, which have a higher heat release than wood.

✓ Store unused pallets outside and away from buildings when possible.

Why Training and Certification Are Necessary

Stacking and moving pallets can be dangerous. All it takes is one improperly stacked pallet rack to cause an accident that leads to serious injury or death. That’s why learning how to properly stack pallets requires specialized training. This training should include forklift operators and other workers who handle pallets.

Forklift accidents happen every day. The most common cause is operator error. In fact, operators without training are the most likely to be involved in serious accidents. Tip-overs and collisions involving forklifts are also common in warehouses. So are accidents involving pallets.

There’s more to proper forklift stacking and pallet stacking than just getting the pallets straight. Workers also need to know how to:

✓ Approach pallets to lift and load them

✓ Approach a stack of pallets to unload them

✓ Safely travel with pallets on the forklift

✓ Properly stack pallets on racks

Workers must be able to perform these tasks in all kinds of work settings. This requires a unique set of skills that can only be acquired through training and practice.

Pallet stacking training is also important for employers. OSHA requires that all workers are trained and certified for forklift use and pallet stacking. If not, employers risk heavy fines and possible legal action from OSHA.
