253,100 injuries and illnesses were reported in the transportation and warehousing sector by the U.S. Bureau of Labor and Statistics in 2021. That marked a 22% increase from the previous year. As accidents are on the rise in the warehouse industry, OSHA is taking a harder look at compliance industry-wide. Their increased vigilance extends to your pallet racking. However, the lack of specificity in OSHA pallet racking standards makes compliance challenging for most businesses. In this article, we'll identify the 4 most common ways to avoid pallet rack citations, as well as how to ensure you have the correct load limits for your racks.
Pallet rack violations are a common citation during OSHA inspections. However, OSHA has few specific regulations for warehouse racking. Instead, they include most pallet racking standards within the general safety clause, which mandates that employers must provide a workplace free of recognized hazards. This lack of enumerated requirements can make compliance frustrating. However, violations can be avoided by following a few pallet rack safety protocols.
Pallet rack load limits vary depending on the manufacturer and model. As such, weight limits are often one of the least understood aspects of compliance. OSHA sets no specific standards for pallet rack capacity. Instead, they refer to the regulations the American National Standards Institute (ANSI) set in standard MH16.1-2023. These ANSI racking standards lay out how pallet racks should be designed, tested, and used. Ultimately, these standards address four vital areas that need to be understood when determining pallet rack load limits.
Pallet rack beam dimensions are either described by beam width or beam length. This is somewhat misleading as both terms refer to the same dimension: the horizontal size of the beam.
To determine the beam length you will need to first decide how many pallets it will support side by side. Next, collect the dimensions of the pallets stored. Then, multiply the width of a single pallet by the number of pallets stored. Finally, add 6 inches per pallet to that number to account for the additional space required by fire code.
For example, if you use standard 40-inch by 48-inch pallets and store two side by side, you'll multiply 40 inches by 2 for 80 inches. Then, add 12 inches for a total beam length of 92 inches.
Beam loading limits are described as capacity per pallet load pair. To determine the maximum weight your beam will need to support, set the maximum weight of each pallet you plan to store on the rack and multiply that by the number of pallets stored on the beam.
So, if you were planning to store pallets that each weighed 1,000 lbs, you would need a beam with a capacity of at least 2,000 lbs per pair.
Manufacturer capacity charts are a great tool to determine what capacity your rack beams can support based on beam length. These charts are invaluable when deciding which beam fits your space and the requirements of your products.
The third factor in determining pallet rack load limits is the rated capacity of the uprights. Collectively, rack uprights must be able to support the weight of each tier to which they are connected. For example, if our hypothetical pallet rack from above will have four tiers, the four uprights that make up the four corners of the rack must be able to support at least 8,000 lbs. If we increase that to 5 tiers, the uprights must now support 10,000 lbs. Additionally, if the upright will support beams on more than one side, it must be rated to handle the weight of the tiers on all sides.
Correct labeling is vital because of the variability in pallet racking weight limits. In fact, this is one of the most commonly cited pallet racking violations. The ANSI standard for storage racks states that racking systems must be identified with one or more load placards that contain the following information:
These labels must be displayed on or near the rack system in a clearly visible spot. Additionally, anytime modifications are made to the rack, the load limits must be reassessed, and the plaque must be updated. While the standard does not include an exact number of labels that must appear per rack, labeling each bay individually is a best practice.
