Maximizing Loading Dock Capacity and the Benefits that Follow

Maximizing Loading Dock Capacity and the Benefits that Follow

Pressure to Increase Throughput

Manufacturing, warehousing, and distribution facilities around the world are faced with the constant pressure to increase production and throughput to meet consumers growing demand for goods. Some facilities do this in a variety of ways such as introducing automated equipment into their manufacturing processes to reduce the amount of time to produce goods. Others redesign the layout of their working environments to optimize space and some even consider adding on to their existing buildings to accommodate the manufacturing or storage of additional goods. These are all viable solutions, but they are costly.

The Loading Dock is a Valuable Asset

The loading dock is an environment often overlooked when operation mangers are tasked with increasing throughput. Loading docks are a key part of the supply chain and are a valuable asset and should be seen as one. Loading docks are what make a site continue to operate day after day, receiving and shipping goods – impacting profits.

An inefficient loading dock impacts the amount of goods able to be received or shipped out of a facility, resulting in low facility throughput. Optimizing efficiencies in this environment will allow for increased throughput and maximized loading dock capacity.

 Benefits of Maximized Capacity at the Loading Dock

Ensuring your loading docks are operating at maximum capacity will not only increase your facilities throughput but also provide several other benefits to your site such as performance optimization, increased understanding, safe working practices, and reduced costs.

Performance Optimization

Ensuring your facility is operating at maximized capacity ensures that site performance is optimized. Through the identification of inefficiencies and bottlenecks  affecting your loading docks, the necessary changes can be made to optimize performance. Some examples of this include utilizing all your loading docks instead  of only a select few and giving dock schedulers full visibility of which loading docks are in use or available – minimizing the risk of incorrect dock assignment.

Increased Understanding

An increased understanding of your loading dock capacity will allow for any results from changes made in dock operations to be tracked. In addition, planning dock activities will become easier as you will now be aware of your limits. Increased understanding of your loading dock will also make the facility aware if they  do truly need to invest funds to expand their facility, add additional loading docks, or introduce automated technologies in other areas of the plant.

Safe Working Practices

To ensure your facility maximizes their loading dock capacity, it is critical the docks are operating in a safe manner. In the US, more than 25% of all industrial  accidents occur at the loading dock while resulting in 270,000 injuries and 819 deaths. Additionally, for every accident there are about 600 near misses  (EHSToday). A safe loading dock environment increases efficiencies as it reduces the risk of downtime resulting from injury or a near miss.

Reduced Cost

It is simple, not operating at maximum capacity is costly, extremely costly. Accidents coupled with inefficiencies and avoidable fines cost the US warehouse   industry well over $80 billion per year. Detention fees, lack of data, poor dock utilization and manual data entry are serious problems that are affecting facilities.    These issues often make it difficult to plan dock activities, hamper site performance, decrease load capacity and result in inaccurate data and high costs.

It is important to understand, measure and operate at your facility’s maximum capacity. Doing this will result in reduce costs, saving you millions of dollars  annually and increasing profits.

Where Trapped Key Solutions Win in Safety!

History of Trapped Key Interlocking 

Trapped key interlocking has been keeping people safe from hazardous energy and environments for over 100 years. A trapped key interlock safety solution ensures that a pre-determined sequence of operations is followed each time and cannot be circumvented or short cut. The transfer of uniquely coded keys ensures that personnel remain safe throughout the process and eliminates human error.

The concept of trapped key interlocking (TKI) dates back to 1893 when French inventor Paul Bouré created engagement locking devices to ensure safe track switching operations. Two years later, Trayvou manufactured interlocking devices for the manufacturing and railway industry. In 1922, an Englishman by the name of James Harry Castell designed the first interlocking system to protect the people and assets during the electrification of London. In the United States, Ralph Levering Kirk was the first to pioneer the use of key interlocking on circuit breakers and switches in early 1930’s.

Where Trapped Key Solutions Win 

Trapped Key Interlock solutions provide a fixed mounted safety solution, customized to the user’s specific application needs, equipment, and processes.  Interlocks are designed to withstand harsh environments and heavy applications where alternative solutions such as safety switching and sensing technology may not perform consistently; and in hazardous situations, failure of a safety solution is not an option!

Trapped key interlocking systems are mounted directly to equipment, gating, and access doors and does not require field wiring or cabling around machinery, assets, or equipment. In many cases, equipment power will be isolated via a key switch mounted on a control panel or isolation unit, keeping all the electrical wiring well away from the hazardous areas. KIRK’s trapped key interlocking products are built to the highest quality, and are extremely robust, being able to withstand harsh conditions such as high temperatures, adverse weather, debris, and even wash down areas. They require little maintenance and are proven to work in challenging environments.

While trapped key interlocking was originally introduced in railway track switching applications, the technology of trapped key systems has continued to develop and is now utilized in many applications across all sectors. From machine guarding safety in industrial applications, operations and maintenance of switchgear, both HV and MV/LV, and even in logistics and warehousing preventing accidents during loading/unloading activities, trapped key interlocking solution can be found.

How a Trapped Key Solution Works

A trapped key interlocking solution consists of 3 defined actions: isolating hazardous energy, transferring or exchanging sequenced keys, and accessing the protected area or equipment.  Interlocks are designed specifically with these action in mind to ensure the comprehensive solutions operates effectively.

An isolation interlock is typically the initiating interlock and ensures the isolation of power.  Once the equipment is de-energized, the interlock key is turned, engaging the bolt, blocking the power switch, and releasing the key.  The interlock is now a physical barrier to preventing the equipment from being re-energized.

Now that power has been isolated, the released key can be taken to a transfer or exchange interlocks where there the access keys are trapped awaiting the introduction of the initiating key from the isolation interlock.  Once the initiating key has been inserted and turned in the transfer block, the access key(s) are now released, and the initiating key is trapped.

The access key(s) can now be taken to the access points and inserted into the access interlock(s). Personnel can safely enter the area with peace of mind that the power has been fully isolated and cannot be re-energized until the trapped key solution is followed in reverse.  The video below demonstrates a simple scheme for safely accessing a restricted area.


Trapped key interlocking systems have been keeping people safe at work for over 100 years. Advancements in technology, the need for real-time data, and remote management is changing the way businesses look to improve on their efficiencies and productivity. We are working to incorporate these technologies into our trapped key solutions with Smart Key Management Systems and Warehouse Insight Systems.  Trapped key safety solutions will remain relevant and often may be the best safety solution especially when it comes to harsh environments and heavy applications where the need to withstand adverse conditions is required.

The Impact of Coronavirus on the Logistics Industry

The Impact of Coronavirus on the Logistics Industry

Changes for logistics & warehouses due to coronavirus 

The coronavirus (COVID-19) pandemic has undoubtedly had an impact on all sectors globally. The logistics industry has proved critical at this time but has also been affected by the circumstances created by COVID-19, undergoing significant changes and facing several challenges.

There has been an enormous need for effective and immediate logistics services due to increased e-commerce activities resulting from the COVID-19 crisis. Since January 2020, existing customers have been purchasing online more frequently, while new customers – mostly people coming from older age groups or rural areas have made an online purchase for the first time. Evidence of the growth e-commerce is facing is the fact that the market capitalization has increased by more than 25% since the beginning of the coronavirus outbreak. Moreover, the Chinese e-commerce sector, which accounted for less than 20% of sales on the market, has also significantly risen.

In addition, supermarkets and grocery retailers specifically have been largely expanding their e-commerce capabilities using home delivery services to cope with the increased customer demand for food and grocery. In fact, between the January 31st and March 20th 2020, the food and grocery market grew by more than 4%. However, to fulfil this customer demand, putting further logistics in place has been a necessity.

Increased risk due to increased activity

This rapid increase of e-commerce has affected the landscape of logistics and warehousing in several ways. As the number of deliveries rises, so does the volume of loading dock operations. With logistics firms facing even higher than usual pressures to ensure on time deliveries of goods and services, the risk of accidents at loading docks (such as accidental drive-aways) also increases. Dock inactivity, the loss of assets, staff, time and loading dock capacity resulting from an accident are only a few of the numerous impacts that could affect a business.

During the colder seasons, truck drivers will be wanting to stay in waiting rooms, but with social distancing in place due to coronavirus restrictions, maintaining social distancing might not always be possible and result in some drivers staying in their vehicles. This decreases the risk of truck drivers contracting or spreading coronavirus, but in some situations might not be best practice and could increase risk of drive-aways. Some companies are even reducing the number of staff on site and using advanced technologies such as remote forklift truck driving, although that can come with additional risks to be considered.


The best way to ensure continued safe operation of the loading dock during this period of increased activity is to have a simple, reliable solution that ensures the safety of the warehouse staff and drivers with minimal operational disruption.

One such available safety solution is the Salvo Loading Dock Safety System. The system’s uniqueness lies in the fact that it interlocks the vehicle’s air brakes with the dock door. Loading/unloading of goods can take place safely, and the risk of accidental drive-aways is mitigated. Moreover, Salvo is very easy to use as personnel need to follow a few simple steps to operate the dock, making the solution easy for all to understand.

Drivers in the vehicle do not pose a risk with Salvo because the air brakes are locked out. Dispatch managers can ensure that accidental drive-aways are prevented and loading/unloading processes take place safely and with minimum disruptions.

The increased risks arising from covid-19 can be mitigated with the appropriate safety solutions in place, allowing for loading docks to operate safely with increased throughput.

Data Center UPS Systems with TKI Solutions

Data Center UPS Systems with TKI Solutions

Continuous, uninterrupted power is critical to our infrastructure. Everything we do is dependent on power, and in today’s COVID-19 pandemic, we are seeing our lives impacted in more ways. Increased online businesses, home offices, and online schooling depend on power and connectivity to outside data centers and servers.  When the potential for power outages, interruptions, or inconsistencies in power occur, it is important that our critical facilities, utilities, and data centers have an Uninterruptable Power Supply (UPS) System and bypass in place to mitigate loss of power.  UPS Systems will protect your facility, hospital, equipment, and/or data from damage, loss of information, and even loss of life.

During a loss of power situation, UPS systems become your facilities temporary power source until load can seamlessly transfer to the back-up power generator.  Having a UPS system in your facility is one thing, but regular maintenance and testing on the UPS system is just as critical.  Regular testing and maintenance must be completed to be confident that when the system is needed, it will function properly.  During both the maintenance and operations of a UPS system, protecting workers and contractors from hazardous energy is imperative.  Implementing a trapped key interlock safety solution into these processes will guarantee the maintenance on the UPS system is properly and safely managed each time.


In a data center, routine maintenance on UPS systems is scheduled.  Maintenance to the system can include but is not limited to load bank testing of the generator to emulate the generator running in back-up mode during a power outage.  During this maintenance process, the generator must be disconnected from the facility power.  KIRK Scheme 39, from the KIRK Scheme book, is an example of a typical UPS bypass system process when implemented safely with a trapped key interlock solution.

When the UPS system does not require maintenance, however service to the utility generator or backup generator is necessary, a similar trapped key interlock solution can be implemented on the Maintenance Bypass System (MBS) to ensure the system has been safely isolated.  This requires the system to isolate power from the facility and safely access the breaker cabinet that is connected to the alternate power source; ie utility generator.

When designing UPS system for a data center facility, it is important to determine the Tier Standard for the facility.  The Tier Standard defines critical components of a data center and provides an uptime metric based on the critical need of the data center operations.  A Tier 1 facility is classed as a non-critical facility and may implement a simple UPS system if any at all.  On the other end of the tier standard is a tier 4 facility, which is classed as the highest level of critical need.  A Tier 4 facility must have a minimum of 96 hours of power outage protection in times of need.  In either situation, a trapped key interlock safety solution will ensure the safety of employees and equipment when performing critical maintenance and when putting UPS systems into operation during a dire power situation.



Whether you are implementing a trapped key interlock safety solution for a tier 1 facility or the most critical tier 4 facility, it is imperative to protect your personnel and equipment.  Designed and customized for each unique situation, a trapped key interlock solution will eliminate human error and ensure the safety of all involved.

KIRK has been delivering safety solutions for electrical systems since 1932.  Working closely with original equipment manufacturers (OEMs) has enabled KIRK to produce interlocks designed specifically for use on the leading manufacturer’s breakers, isolators, and disconnects.  KIRK’s comprehensive product offering of energy isolation and safe access interlock products for UPS applications ensures the right solution can be implemented for any level of critical power.  Mounting provisions often supplied by OEMs enable the interlocks to be easily incorporated however, if a unique mounting provision is required, KIRK’s Applied Engineering Services team can design a customized interlock or provision to meet the requirements.

How an Interlock Solution Can Ensure Safe Gangway Loading

How an Interlock Solution Can Ensure Safe Gangway Loading

Tankers and the Industries they Serve

Industries such as oil & gas, food & beverage, chemical, and agriculture require goods to be transported by tanker truck. Commonly, these vehicles carry granular or liquid goods like fuel, flour, sugar or plastics. These types of goods require specialized procedures to unload and load their goods.

Loading/Unloading Process

When a tanker truck has reached its destination, it enters the unloading/ loading area of a facility where hoses and or pumps are connected to the tank to unload or load the goods. It is common that tanker personnel will need to gain access to the top of the tank to allow for ventilation or attach hoses/pumps to begin the loading/unloading process. Many facilities have permanent or semi-permanent elevated loading platforms or gangway systems that allow authorized tanker personnel to safely access the top of the tanks.


While gangway platforms offer personnel ease of access, they also pose some risk.  Property damage can occur when a tanker believes that the loading or unloading process is complete and begins to pull away from the loading site as its hoses/pumps are still connected. As a result, the gangway and other equipment could become damaged.

Not only is equipment and property damaged when the tanker pulls away from the gangway, but personnel is also at risk for injury or even death. The OSHA 1910.28 standard requires fall protection devices such as a guardrail, safety net, or personal fall protection systems to be in use if an employee could fall more than 4 feet or more from an opening. While most gangways or loading platforms meet this standard by using guardrails, accidents can still occur.

In addition, it is common for tanker trucks to carry flammable or corrosive liquids which makes the safe loading/unloading of this material imperative for both the personnel and facility. OSHA states, “Truck or rail tank car loading or the unloading of flammable/combustible liquids is one of the most hazardous operations likely to be undertaken at any manufacturing or storage facility.”


To mitigate these risks, the tanker truck needs to be prevented from departing from the gangway before loading or unloading is complete. The Salvo Loading Dock Safety System is a robust solution that prevents early departures from occurring. The system forces a sequential process to be followed that ensures the tankers are locked out before personnel can access the gangway to begin their loading/ unloading procedure.

The tankers air brakes are first locked out by using a uniquely coded glad-hand. When the glad-hand is applied the key can then be removed and taken to the manual door lock. The manual door lock is typically mounted on a post where personnel would access the gangway. The door lock would contain a short bolt and long chain that restricts access to the gangway until the Salvo key has been inserted into the door lock and the bolt has been removed, granting access to the gangway. When the loading process is complete and the gangway has been retracted back to its original stored position, the bolt is reinserted into the door lock, releasing the key. The key can then be taken to the glad-hand where it is reinserted and the glad-hand can be removed. The Salvo Loading System prevents early departures and ensures personnel are safe.

Access Control in the Energy Sector

Access Control in the Energy Sector

Ensuring the safety of personnel and equipment when accessing hazardous energy areas is imperative. Within the energy sector, maintenance of electrical transmission and distribution equipment often involves multiple power sources to be isolated across the system before personnel can be assured it is safe to enter and they are out of harm’s way. Following a predefined sequence of operations to manage safe access to machinery and electrical equipment is essential for the safety of all involved.

Implementing a trapped key interlocking (TKI) system that has been designed to specific criteria and having the system properly installed, ensures the isolation and earthing conditions can take place under the safest of conditions. A trapped key interlock system provides a visual, physical barrier on switching equipment that indicates the power isolation operations have been completed. A personnel key can also be coordinated into the solution as the last step in the sequence, providing the operator control of the full interlock system until maintenance has been completed and power can be safely restored. Trapped key interlock solutions are flexible enough to be re-configured if the need to incorporate changes to safety procedures arise or if new equipment is integrated into the operations.

Typical examples of access control in the energy sector include maintenance of electrified equipment such as switchgear, capacitor banks, back-up power or ups systems, and transformers.

Benefits of TKI over Alternative Solutions

Electrical interlocking allows for the sequential operation of switches. An example of an application within substations implements an electrical interlocking scheme allowing for the safe operation of disconnects, however, when maintenance activities are being performed, there is a need for a site controlled mechanical device. A mechanical trapped key interlock solution device allows the site operative to complete the sequence of interlock events to release the final authorization key or permission to access key. This final key means that the sequence of operations can only be reversed an controlled by the personnel performing the maintenance activities.

To compare TKI systems to LOTO; LOTO gives the operator control over the environment they are working in and is an effective form of protection. It is a padlock-based/identifiable process that aligns with detailed written operating procedures and signage to visually show the maintenance environment is protected. However, if the procedures are not followed or signage not obeyed, this can cause an unsafe environment on site. Trapped key interlock systems can be integrated within a LOTO procedure or implemented as an alternative method for controlling hazardous energy, as they are recognized by the guidelines of ANSI Z244.1 Integrating a TKI solution can reduce the opportunity for procedures to be skipped or followed out of order, eliminating human error and further mitigating damages.


Access control in energy applications can be far more complicated than other sectors, owing to the fact that it is part of a larger site system with multiple energy sources. The uniquely identified trapped key system provides a full safety system to ensure safe access to multiple power sources and hazardous areas.

KIRK has operated in the energy sector worldwide since in 1932. KIRK products have safeguarded thousands of lives and ensured the safe operation of critical equipment aiding in the efficient operations and maintenance within the energy sector with less down time and higher operational safety.

The Changing Landscape of Warehouse Safety

Warehouse and Logistics White Paper

Kirk Key Interlock has over 80 years of experience in industrial safety across a wide range of sectors such as manufacturing, waste & recycling, concrete and warehousing. Recently, we have made use of this expertise and knowledge to produce a white paper on the changing landscape of warehouse safety in the US.

More specifically, the white paper below touches upon the changes in the warehouse industry and their effect on safety, as well as the benefits of safety equipment. It also illustrates how adopting best safety practices could not only minimize risks (such as accidental drive-aways at loading docks) but also deliver a return on investment by eliminating downtime and the costs resulting from the loss of assets and staff.

Changes in the Warehousing Industry

Warehousing is an enormous industry that is an essential part of the modern world and is constantly adapting to new demands. Supply chains are becoming more complex and warehouses are becoming distribution centers – where goods are finished, picked and packed rather than old-fashioned storage areas. IBIS World calculates the revenue of the public storage and warehousing industry in the US to be $25bn, with an annual growth rate of 3.7 per cent over the past five years. This involves just over 20,000 businesses and the employment of almost 270,800 people.

Improve Safety & Efficiency of Lift Gate Trailer Loading at the Docks

Lift gate trailers

Lift gate trailers are beneficial for shippers as they provide the means to load/unload shipments without the need for a loading dock. Trailers equipped with a lift gate can be loaded / unloaded by lowering the cargo to the ground on the lift gate and cargo can then be moved with the use of a forklift or pallet jack. However, lift gate trailers pose a unique safety dilemma when arriving at a loading dock, as typical safety hook restraints cannot be used to secure the trailer to the dock. An unsecured trailer at the dock presents an unsafe loading / unloading environment for forklift operators and dock workers.

What’s the risk?

In the United States there are 97,000 forklift accidents reported each year, resulting in injury and or fatality. Of these reported incidents, 7% of those accidents occur during loading / unloading of a trailer. These loading/unloading occurrences could have been prevented if the proper trailer restraint system was implemented at the dock. However, many loading docks across the United States are setup to only safely accommodate traditional trailers with rear impact guards, also known as Interstate Commerce Commission (ICC) bars, that accommodate restraint hook capability and do not have a safe option for trailers equipped with lift gates.
A trailer equipped with a lift gate prevents the use of the ICC bar with a hook-restraint device. Due to the mounting of the lift gate, a hook restraint is unable to properly attach to the ICC bar and significant damage to the restraint hook and property can be sustained when used with a lift gate trailer. Chocks can be implemented for lift gate trailers, as they are an acceptable Occupational Safety and Health Administration (OSHA) option for trailer safety, however, chocks offer minimal protection against trailer movement and can provide a false sense of safety during the loading / unloading process. Chocks do not provide an effective barrier to preventing drive-away, potentially pulling away while a forklift operator remains in the trailer or even caught between the back of the trailer and the dock edge. So, what type of restraint system can be implemented to ensure maximum safety for loading / unloading these trailers?

What’s the solution?

Salvo Loading Dock Safety Systems can ensure the safe loading / unloading of lift gate trailers at docks and provide the same level of safety for all trailer types. Salvo systems ensure a predetermined sequence of operations when restraining the trailer at the dock. Once the trailer is parked at the dock, Salvo’s patented glad hand with interlock technology is secured to the trailer’s emergency brake coupling, interlocking the trailer with the dock door.

The released key from the glad hand is then inserted into the Salvo Control Panel, trapping the key, and communicating to the dock employees via a traffic light system that the dock door can be opened and it is safe to load/unload.
Only once the process is complete and the dock door is locked, can the key be released and returned to the glad hand, allowing the air-lines to be reconnected and the driver to safely depart.

Salvo Loading Dock Safety Systems provide:

• Versatility: A complete restraint system for all trailer types providing full dock safety system
• Communications: Truck drivers and forklift operators are aware of loading/unloading progress
• Regulations: Conforms to OSHA loading / unloading compliance 29 CFR 1910.178

Implementing a trailer restraint system that ensures a maximum level of safety for all trailer types, with no limitation, allows greater safety and loading / unloading efficiencies at the docks. Salvo Loading Dock Safety Systems eliminate human error and ensures the safest possible lift gate trailer loading & uploading.
