A HOT CATEGORY Cold storage facilities play a critical role in many industries, from food and beverage to pharmaceutical, electronics and more. With regulatory changes, technological advances, macro-economic trends and other factors, best practices for cold storage facility operation and design have undergone a number of changes recently. This guide is designed to give facility managers an overview of those changes, the trends behind them and potential solutions for ensuring efficiency and compliance. While the numerous studies done on this category don’t always agree, one thing is clear in all of them: the cold storage industry is growing steadily. According to sources such as Global Cold Chain Alliance and DatexCorp, the total capacity of cold storage warehouses has been increasing at roughly 4% annually since 2013 and is expected to continue.

This expansion has been driven by a variety of factors, including the boom in global frozen food consumption. Frozen food sales are projected to reach $306 billion by 2020, equating to a compound annual growth rate (CAGR) of 4.1% from 2015-2020. There are other factors, as well, not the least of which is the United States’ (and world’s)

ever-increasing population, which ensures increasing demand. Industrial real estate firm CBRE points to changing consumer behaviors as another factor, particularly the surge in online grocery shopping. Per FMI/Nielsen data, online grocery sales are expected to rise from $19 billion in 2017 to $100 billion by 2024. Logistics Management magazine notes that the increase in online consumers “has the potential to drive up demand for roughly 35 million square-feet of US-based cold storage spaced moving from retail stores to warehouses and DCs over the course of the next several years.”

Conversely, some analysts predict that demand for cold storage space may increase among major food retailers. While retailers currently control about 22% of space in the U.S., investment firm JLL speculates that percentage may increase as major food retailers such as Walmart, Target and Costco opt to bypass wholesalers and buy directly from manufacturers, using their own facilities for cold storage.

BIGGER, TALLER FACILITIESTarget is at the forefront of a trend that applies across all cold storage subsectors: a shift toward larger, multi-story facilities. According to the Global Cold Chain Alliance and DatexCorp, the total capacity of cold storage

warehouses has been increasing at roughly 4% annually since 2013. However, the actual number of facilities is only projected to increase about 1% CAGR for the next five years, meaning much of that growth has been upward.Industrial real estate firm CBRE estimates that average warehouse heights have increased by more than one-third since the 1960s.

This is partially due to an increased need for warehouses in urban areas, where real estate is more expensive, and partially due to the high cost of building and operating a cold storage facility. Because of their sophisticated freezer and cooler needs and comparatively high energy usage, the cost of operating cold storage facilities can be as much as 3 times that of operating conventional warehouse space.

In 2013, Target opened a 360,000-square-foot, nine-story facility in the Dallas suburb of Denton that can keep foods at temperatures from -5 to 34 degrees Fahrenheit. Target is currently developing a 500,000-square-foot warehouse in Southern California and a third mega-warehouse in northeastern Ohio. All are highly automated, as is the newly opened 130-foot-tall New Cold seafood facility in Tacoma, Washington.


Regardless of their size or inventory, all cold storage facilities (and supply chains) share some universal challenges, with the first and foremost being cold chain integrity. A cold chain can break down at many different points from point of origin to the consumer. Inconsistent temperature control during shipment, poor temperature control inside the warehouse, and product sitting on an open dock (or in an open trailer) too long are all common scenarios for cold chain disruption. Considering the value of a standard OTR food shipment is between $50,000 and $100,000, with reefer loads going up $1 million (and pharmaceutical loads up to $50 million) any glitch in a cold chain’s integrity can become an immensely expensive mistake.

Cargo theft is also a widespread problem. The FBI estimates that cargo theft is a $30 billion a year problem, with food the most targeted type of cargo. Statistics indicate there is a growing trend of cargo thefts at warehouses and distribution centers and even in trailers that had been backed up to dock doors. According to CargoNet, more than a quarter (27 percent) of all cargo thefts reported in 2016 took place at warehouses or distribution centers. Furthermore, the common practice of truck drivers breaking a trailer’s security seal on the drive approach also puts companies at risk. Security or surveillance may not be present on the drive approach, which means food could be easily stolen, tampered with or even poisoned and used as a threat.

Employee safety is a concern at all warehouses, whether they are cold storage or dry goods. Loading dock areas

are particularly dangerous, accounting for nearly a quarter of all industrial injuries. This isn’t surprising, considering the number of forklifts maneuvering around towers of pallets and product with a fair amount of foot traffic mixed into such a small area. Dock exteriors are also a dangerous area. There are hundreds of forklift accidents annually due to trailer creep, trailer tip-over or trailers pulling away from the dock prematurely. Tractor trailers are also the second-leading cause of back-over deaths in America, and the risk isn’t isolated; many international governments are recommending aggressive solutions to address this danger at the dock.

Inside cold storage facilities, large blast freezer doors can be notoriously difficult to open without multiple people. Workers who attempt to open them with unsafe methods – like using a forklift – can damage the door or cause an injury to themselves or others. Multi-story workspace and storage areas also create risk for fall-related injuries or injuries due to falling product. In fact, falling object accidents are the leading cause of nonfatal occupational injuries requiring hospitalization, with nearly 28,000 incidents every year.

Regulatory compliance is another common challenge for cold storage facilities, particularly in the food sector. Cold chain integrity plays a vital role in meeting standards outlined by the USDA’s Food Safety Modernization Act (FSMA), as well as current Good Manufacturing Practices (cGMP) and Hazard Analysis Critical Control Point (HACCP) protocols, which are commonly used in the pharmaceutical, as well as food industries.

Other Cold Chain Challenges

STEPS TO TAKE WHEN RECEIVING FOOD SHIPMENTS The vehicles should be clean and in good condition.

There should be no evidence of insect or rodent infestation.

There should be no offending odors that might be absorbed by the materials in the vehicle.

The product and the pallets on which the product was shipped should be in good physical condition.

For refrigerated or frozen deliveries, the products must meet established specifications for delivery, specifically in terms of temperature control.

The bill of loading must match what is in the vehicle.

There is no evidence of tampering.

If this is a refrigerated or frozen load, the cold air deflectors and the load temperature should be maintained properly in all four corners, especially at the back door.


Perhaps no regulatory action has created more challenges than FSMA. Among many other things, the FSMA requires more detailed record keeping by all parties involved in the supply chain, particularly temperature control documentation. The aspects of the law that are expected to have the most impact on supply chain service providers are the preventive controls and sanitary transportation rules. The preventive controls rule applies to companies involved in cold storage (in addition to manufacturing) while sanitary transport impacts companies involved in arranging shipping, loading, carrying and receiving food transported by truck and rail.

Due to the FSMA’s Sanitary Transportation Rule, 3PLs are now considered “shippers” and are thus

held to strict standards that might have previously only been reserved for manufacturers. Lowell Randel, vice president of government and legal affairs at GCCA, said:

“You look at some of our refrigerated warehouse members, and at a very minimum, they’ll be a receiver under the new rule. Many of those warehouse members also will be loaders. And while not owning the product, warehouses often will be arranging for the transportation, and that’s an important distinction. They may not see themselves as the shipper, but the rule very clearly indicates that third-party entities, brokers and warehouses could very likely be shippers for the purposes of the rule, which means they will have this long list of responsibilities.”

How Good Food Goes Bad

FSMA Spells Big Changes For Cold Storage

MORE DOCUMENTATION:Shippers must now specify all sanitary requirements of the shipment to the carrier, inspect the carrier’s trailer, confirm its temperatures and keep documented records. Carriers must provide information covering the trailer’s previous three cargoes and cleanings in between.

INCREASED TRAINING: The FSMA requires increased training for shippers, carriers and receivers, with particular emphasis on temperature monitoring and control. Training records must be maintained for all personnel for 12 months after they leave their job.

EXPANDED RESPONSIBILITIES: The FSMA’s Sanitary Transportation rule expands the definition of receivers to include third-party logistics warehouses (3PLs). In some cases, 3PLs will also become shippers for purposes of this rule.

IMPROVED TECHNOLOGY: The increased record-keeping required by FSMA has made data-loggers and RFID tags standard equipment across the supply chain and is expected to hasten the widespread adoption of blockchain smart ledgers.

CONDENSATION PREVENTION:Cold storage facilities must now put verifiable frost and condensation control measures in place or risk losing FDA registration. Building defects are no longer an excuse. (This includes droplets from refrigeration units, moisture near docks or drops from the ceiling.)


Fortunately, a number of new technologies and facility designs have been developed recently to help cold storage warehouses and distribution centers handle these challenges – and become more energy efficient and productive in the process.

DRIVE-THROUGH DOCK DESIGNThe loading dock is the gateway for products in and out of any cold storage facility. A traditional loading dock requires truck drivers to break the security seal and open the truck doors before finishing backing in and docking. If this process isn’t completed in a timely manner, it could damage temperature-sensitive products. It also creates opportunities for theft, tampering and drive approach accidents.

The gold standard for any industry that depends on a strong cold chain is to implement a “drive-through” application at the loading dock. In addition to securing the cold chain, this loading dock solution can prevent product from being tampered with or stolen and helps maintain

cold chain integrity, environmental control and security.A drive-through set-up requires more than just one product; it entails a system of equipment that works together. The core component is a vertical storing leveler. This allows the trailer to back all the way into the dock before the security seals are broken and trailer doors can be opened into the building – meaning loads are never exposed to outside weather or contaminants and people are kept out of harm’s way on the drive approach.

Unlike a pit-style leveler, a vertical leveler (when in the stored position) allows the loading dock door to close directly on the pit floor instead of on the leveler, which effectively reduces energy loss by minimizing outside air infiltration.

The other key to a drive-through application is creating a complete environmental seal between the back end of the semi-trailer and the inside of the loading dock. This can be done with loading dock shelters specifically designed for drive-through docks.

Through special design features, these shelters provide tight sealing against trailer sides, across the full width of the trailer top and at the corners, without interfering with trailer doors being opened and closed after the trailer has been parked at the dock and secured.

AGVs AND AS/RSHigh-tech, automated and robotic technologies, including automated guided vehicles (AGVs) and automated storage/retrieval systems (AS/RS), have become increasingly commonplace in all types of industrial facilities in the past decade. This is certainly true for cold storage facilities, where AGVs are regularly used to improve throughput speed of products from end-of-line equipment to shipping. AS/RS systems are also widely implemented to improve safety and efficiency throughout cold storage facilities. As distribution centers continue to grow vertically, these automated picking systems can effectively and safely reach product at various levels without putting the human workforce in dangerous situations.

Best Practices: New Design and Technology

In a drive-through dock application, semi trailer doors open into the building. Special dock shelters are also a key to drive-through dock applications.


RADIO FREQUENCY IDENTIFICATION (RFID)Spurred by the FSMA’s requirements for shipment data and documentation, another important new technology has become common in cold storage facilities recently: wireless radio frequency (RFID) identification. RFID utilizes scanned tags to provide tracking information such as product movement, time spent in transit and temperature fluctuation data. At the loading dock, RFID helps manage the flow of goods throughout the warehouse, while drastically reducing labor hours. RFID tags, when integrated with an existing warehouse management system (WMS), will indicate a product’s destination, such as cross-dock movement or in-house inventory location, vastly improving throughput speed at the receiving dock. Standard loading dock procedure has always involved cumbersome bills of lading or packing slips. By removing this human element from cold storage monitoring, RFID systems minimize errors and reduce the need to open the product container at all. Outbound shipments benefit, too. RFID tags share a product’s location from source to its final destination, no matter the method of transportation. This smart supply chain boosts product visibility throughout the cold chain improving the management of perishable andtemperature-dependent products, enabling suppliers to deliver a fresher, higher quality product for the consumer.

BLOCKCHAIN SMART LEDGERSLooking forward, an even newer technology is set to become an industry standard: blockchain. This database, which is also the technology at the base of Bitcoin, provides a smart contract ledger for the exchange of goods between two parties. As a product is only represented at one place within the blockchain database, both parties can securely and safely manage the transaction. For example, in response to the recent, widespread e-coli outbreak in romaine lettuce supplies, Walmart announced in September of 2018 that the company would be implementing a blockchain-powered supply chain monitoring system. This smart contract technology will require more than 100 suppliers to input detailed information about their products into a blockchain database upon initial distribution, which will allow Walmart to closely monitor for spoilage and other red flags along the supply chain.

LIGHT COMMUNICATIONS AND MOTION SENSOR SAFETY SYSTEMSAs mentioned earlier, loading docks are inherently dangerous places. Thankfully, new technologically advanced dock safety systems – incorporating motion sensors, LED lights, audible/visual alarms and interlocking controls – are now available to make these critical work areas safer than they’ve been in the past. In some cases, these systems can be added as stand alone units as budgets allow, provided facilities install upgradeable equipment as the basis for their dock management system.

The newest of these products are motion sensor-based systems designed to protect workers both inside and outside the dock. One such system projects a blue light onto the leveler whenever activity is detected inside a trailer, alerting workers nearby that a forklift, pallet jack or pedestrian could be coming out at any moment. It can be added to any dock, or can be integrated with advanced control boxes to keep the vehicle restraint locked until activity in the trailer stops, ensuring the truck doesn’t pull away with a forklift operator still inside.

The drive approach outside of the loading dock is equally dangerous, although collisions here typically involve a semi-tractor trailer rather than a forklift. Given the ambient noise and the distance between a loading dock and the engine of a semi-tractor trailer, inattentive dock yard workers may not hear a tractor trailer backing toward them until it is too late.

To address this challenge, docks can be equipped with external sensors, which trigger an audible and visual alarm to alert workers outside the dock when a trailer begins backing in, and provide them adequate time to remove themselves from danger.

Some vehicle restraints even include these hazard recognition and control features as standard. Both the internal and external warnings can be incorporated into a comprehensive system using red and green LED lights to indicate a docked trailers status. When the trailer is locked and safe for forklifts to access, green lights will activate inside at the top corners of the dock opening and a red light will come on outside. When the trailer restraint is no longer engaged, the interior dock corner lights change to red while the exterior light turns green (indicating to the driver it is safe to pull away).

The Rite-Vu Hazard Recognition System projects a blue light outside of the dock opening when motion is detected inside the trailer.

Rite-Hite’s Approach-Vu sensor triggers a visual and audio alarm when trailers back into a dock.


SMART CONTROLSBeyond the tangible technology upgrades, the growth in “smart” technology is making it possible for cold chain storage workers to glean real-time data, operate equipment remotely, interlock multiple pieces of equipment and to integrate equipment operations into building management systems (BMS) and security systems. From high-speed door controls to loading dock control panels to high-volume, low-speed (HVLS) fan controls, touch screen technology makes it simple to operate and troubleshoot heavy machinery without the need for personal protective equipment.

CONDENSATION AND FROST PROBLEMSAs one might expect, various forms of water can cause some of the biggest problems with cold chain integrity and worker safety. When warm air infiltrates cooler environments, condensation – and in some cases, frost – can develop.

Condensation and frost on the floor can cause safety hazards inside the facility for workers who might slip. Furthermore, condensation can lead to diminished product quality and compromise the safety of food and pharmaceuticals.

New rules established in FSMA addresses condensation, especially as it relates to water dripping onto stored food. Cold storage facilities can’t simply cite building defects as an excuse and are expected to comply with FSMA by finding verifiable and documentable solutions to frost and condensation buildup.

Frequently called “sweating slab syndrome”, condensation forming on the ground is a common problem in facilities with concrete floors. This usually happens due to warmer air entering through open loading dock doors or gaps between trailers and the perimeter of the dock opening during loading and unloading. Because negative pressure is typical of most facilities, warmer outdoor air (especially in refrigerated/cooler dock areas) typically rushes inside.

Extremely harmful condensation can also form on products that have high water content, like fruits and vegetables, which can cause spoilage. Even products that don’t immediately spoil can be compromised and become harmful to consumers who eat them later. Condensation is a common factor in many listeria cases.

Many facilities combat this problem with environmental seals and shelters at loading dock openings. The most advanced dock shelters can eliminate virtually all gaps along the dock perimeter to minimize air infiltration, as well as any debris or pests.

HVLS fans also play a role in mitigating condensation buildup on and near the floor. Through a process called destratification, HVLS fans unify air temperatures from floor to ceiling. An HVLS fan can transform a tall facility with a 20-degree F difference from ceiling to floor into a single degree. Instead of cool air settling on the ground where warm air can condense, temperature and humidity levels that become uniform diminish condensation development.

Similar to condensation, frost can develop near especially cold areas. It’s not uncommon to find frost near doors and door openings that separate freezers from warmer working areas. This frost can lead to worker safety issues and also increased risk for air infiltration in instances that affect a freezer door from closing.

This low-voltage GUI (Graphic User Interface) door control box eliminates the need for personal protective equipment, provides valuable data and can be integrated into BMS.

HVLS fans help minimize condensation by creating uniform temperature and humidity levels.


NEW COOLER AND FREEZER DOOR TECHNOLOGIESDoors and walls play important roles in facility safety and work zone separation, as well as cold chain integrity. High-speed fabric roll-up doors are becoming more popular across all types of industrial facilities due to their forklift-friendly safety design. A forklift collision with traditional, bi-parting doors can lead to driver injury, product or equipment damage and costly downtime due to repair. Fabric doors allows them to withstand forklift impact and snap right back into their tracks – greatly reducing both downtime and energy loss as compared to traditional doors.

Cold storage facility managers are also becoming increasingly aware of the energy-efficiency benefits of high-speed doors as opposed to slow moving traditional doors with high R-values. In addition to food, they are highly applicable for keeping pharma product within heavily regulated set temperature levels mandated by government agencies like the Food & Drug Administration (FDA). This awareness shift is taking place globally, with the International Energy Conservation Code (IECC) recognizing the importance of high-speed doors. Its 2015 edition includes a revision to Table C402.4.3, which describes the maximum air infiltration rates for fenestration assemblies. As a draft copy of the table notes, their fast cycle times (up to 100 inches per second) minimizes air exchange, which is a key part of reducing overall energy losses through a door opening.

Blast freezers present their own unique set of door challenges. Also known as “shock” freezers, blast freezers are widely used in the food industry to quickly freeze everything from TV dinners to fish to ice cream. Unfortunately, these massive blast freezers present a threat to in-plant safety for employees and equipment. The size, pressure and frost build-up in many blast freezers often makes the insulated panel doors very cumbersome to move. In some cases, these large doors (which can be as a large as 25 feet by 25 feet) have become so heavy and hard to open that employees have resorted to dangerous methods to open them, such as using a forklift. When left open even a crack, these doors can waste large amounts of energy.

Recently, customized curtain walls have been designed specifically for blast freezers – potentially eliminating the need for heavy and dangerous insulated panel doors. Engineered to be light and easy to use, blast freezer curtain walls form a safe and affordable airflow and thermal barrier and can be operated by a single person. This seal minimizes the build-up of ice on the floor at the base of the doors, reducing the chance of employee injuries from dangerous slips and falls, while also redirecting the chamber’s airflow, reducing blast cycle times and lowering energy consumption.

Blast freezer curtain walls are constructed of 18-ounce, industrial vinyl fabric surrounding a layer of anti-microbial polyester batting, nested in a tubular steel frame.

Top Image: Rite-Hite’s Blast Freezer Curtain Wall, which can be operated by a single person, minimizes energy consumption and ice build-up.

FALL PROTECTION EQUIPMENTGiven the trend toward ever-taller cold storage facilities, fall protection equipment has become more widely used than ever before. Based on current standards, industrial mezzanines must have handrails and gates around all edges; however, these gates need to be opened from time-to-time to accommodate the loading and unloading process. According to the ANSI standard, companies must provide full-time protection when loading and unloading materials from an elevated platform – there can be no exposed areas where an employee could potentially fall. As a result, many companies are seeking a solution to secure elevated work environments.

Dual reciprocating barriers are a common choice for this application, since they create a controlled access area in which the inner gate and outer gate cannot be opened at the same time. Leading models use a link bar design that ensures both gates work in unison; when the outer gate opens to allow pallets in, the inner gate automatically closes to keep workers out. After the pallet is received, mezzanine-level workers open the inner gate to remove material from the work zone while the outer gate closes to secure the leading edge of the platform. A safety latch that can only be accessed when standing outside the work zone prevents the outer gate from being raised by a worker inside the work area. Although automatic barriers are available, leading manual barriers

are relatively easy to use. Look for designs with a raised toe board to prevent materials from accidently being pushed off the elevated edge.

In addition to mezzanines and elevated work platforms, many companies are integrating multi-level pick modules within their facilities to handle order fulfillment. Pick modules are typically constructed using a metal support structure, flooring, stairways, handrails, and landings. Products are stored in shelving and racks and are “picked” to conveyors, totes, carts, and other transportation systems.

Multi-level rack systems pose a number of challenges when it comes to securing open areas during the loading and unloading process. The work areas are typically very small and are contained within the rack system itself, which makes it difficult to integrate traditional safety barrier designs.

While they function similarly to reciprocating mezzanine barriers (inside gate can’t open when the outside gate is, and vice versa), they utilize the existing rack structure to minimize the footprint in existing or new installation rack bays. Leading models can fit within virtually any type of rack configuration and meet applicable OSHA standards, as well as other types of regulations.


Rite-Hite’s GateKeeper dual reciprocating mezzanine gate ensures full-time safety at the edge of a mezzanine platform

by keeping one gate closed at all times.

The cold storage industry is undergoing a massive shift. New regulations are putting an increased emphasis on product integrity and safety. Advanced technologies are allowing for more efficient and transparent operations. Consumer behaviors are driving an Amazon effect of bigger and taller warehouse storage.

As a facility manager, it’s vital to stay on top of all these trends and make sure your facility is staying ahead of the curve with the newest technologies and procedures to ensure the stringent standards and increased customer demands are being met. From drive-through loading docks and airtight seals on the exterior of the plant to high-speed doors, smart controls and advanced safety systems on the inside, there are numerous ways to deliver a prosperous future.
