Accidents can happen, and injuries can occur if proper precautions are not taken. In this article, we will explore essential safety tips for opening and closing shipping container doors, ensuring that this crucial aspect of the logistics process is conducted with utmost care and caution.

The Significance of Safety

Safety in the logistics and shipping industry is paramount. The massive size and weight of shipping containers, combined with the potential hazards they present, necessitate strict safety protocols. Whether you are a seasoned professional or a newcomer to the world of shipping, adhering to safety guidelines is non-negotiable. Accidents can result in injuries, damage to cargo, financial losses, and even loss of life. Therefore, it is vital to be well-informed and prepared when dealing with shipping containers, starting with opening and closing their doors.

Why are the Doors of My Shipping Container Difficult to Open/Close?

Here are some likely reasons a shipping container door will not open or close. Our hand leverage tool / shipping container door extension handle helps to address these issues.

• Rust and Corrosion: The hinge pins and blade are seized due to corrosion.  As shipping containers navigate through diverse weather conditions and environments over time, they become susceptible to rust and corrosion. These corrosive agents can target the locking mechanisms and hinges, ultimately impeding the smooth operation of the container's doors. This accumulation of rust and corrosion introduces a layer of complexity to unlocking and opening the container.
• Maintenance Neglect: Regular maintenance is pivotal to sustaining the functionality of shipping containers. The absence of consistent upkeep can lead to complications with the locking mechanisms, hinges, and seals. Without proper lubrication and care, these components might stiffen or become challenging to manipulate, thereby escalating the difficulty of opening the container.
• Physical Impact: The nature of shipping exposes containers to a barrage of wear and tear, stemming from transportation and handling activities. Consequently, the containers might acquire dents, twists, or misalignments. These physical distortions can hinder the proper alignment of the doors, rendering the opening process arduous.
• Uneven Placement: Placing a shipping container on uneven ground can disrupt its frame's equilibrium. This misalignment can extend to the doors, making them difficult to open or close. The uneven stance of the container introduces an extra layer of complexity when trying to access its interior.  Doors and lock rods may warp or the container frame is racked so that the door gear will not operate correctly. This may be caused by cargo shifting during transit. Look at the container to make sure that the doors are aligned and level, both top, and bottom.
• Temperature Influences: Drastic temperature variations encountered during transportation can trigger material expansion and contraction. This phenomenon reverberates through the locking mechanisms and hinges, potentially impairing their normal operation. The impact of temperature fluctuations compounds the challenges associated with opening the container.  Water has become trapped between frozen shipping container doors, particularly relevant to refrigerated cargoes, or containers with moisture-releasing cargoes in cold weather.
• Inadequate Tools: The task of opening a shipping container may necessitate specialized tools such as heavy-duty bolt cutters or unique locking mechanism tools. In the absence of these tools, the process can become considerably more demanding.
• Sealing Complexity: Some shipping containers employ adhesive materials or seals to ensure the contents remain shielded from environmental elements. Over time, these seals can harden and resist breaking. Consequently, accessing the container requires overcoming this intricate sealing mechanism. 
• The door gasket has been damaged and is preventing opening. Door gaskets are designed to present two or more fins against the structure or adjacent door. These are generally flexible but when the gasket is damaged, they may become hard or blocked thus jamming the door closed, or preventing it from being closed. 
• Security Enhancements: Certain shipping containers incorporate robust security features to discourage unauthorized access and potential theft. Although these features are indispensable for safeguarding the contents, they can inadvertently increase the intricacy of opening the container.
• The Covid economy had also released many shipping containers in the world which are now often reused and the issue of hard-to-open/close used shipping containers is now a more common issue than ever.

Injuries from Opening/Closing Hard-to-Open/Close Shipping Container Doors

On a freezing morning, when ice has seized a car door shut, one would never consider using a crowbar to open a car door.  The same thing goes for shipping containers.   While conditions may be more extreme in container operations, is it reasonable to use that kind of force to open or close container doors? Experience suggests that it is not, and often ends with someone being hurt.

Injuries to personnel involved with container door opening and closing are increasing, and often it is as a result of an inappropriate technique that is being employed. We might expect container doors to open and close as if they were car doors, without understanding why this might not be the case.

Starting with the structure of container doors, most will have four or five hinges per door. The mechanics at the point of manufacture is that the hinge pins must be all aligned on the same plane (vertical and horizontal) and in line. Offset hinge pins will result in the blade binding when it is rotated about the pin – the more the misalignment, the greater resistance will be encountered during operation. At the time of manufacture, therefore, it might be expected that the hinge pins on every door are aligned and free to fully open (270º of operation).

Let’s assume that the container is presented in pristine or well-maintained condition; why might the door not open with ease? Containers are generally either on a trailer/chassis or on the ground, and in both cases, the position of the locking gear handles are at an inconvenient height. For best results, the handles should be directly in front of you and at a height that is above the waist and below the shoulders.

The technique is all-important. Start with the two lock rods on the right-hand door, lift the handles out of the retainers and rotate them together as far as they will go. This should be more than 90º and rotation beyond 90º often initiates the container door opening process by forcing the cams out of their keepers. Then grasp the vertical locking bars, one in each hand, so that your hands are just below shoulder height and pull back with your body, using your leg muscles rather than your back.

If the door is still stuck, unless specifically advised against doing so (ie. the container is carrying a flexitank or bulk cargo), open the locking bars on the left-hand door and then grasp the inner locking rod of both doors and pull back, again using your body not your back. If the door still will not open, ask a colleague to pull on one door while you pull on the other.

Injuries almost always occur at the point frustration takes over and mechanical means are employed – the crowbar or a fork truck. So why will the door not open? Generally, this can be attributed to one of four reasons:

• The container frame is racked so that the door gear will not operate correctly. This may be caused by cargo shifting during transit. Look at the container to make sure that the doors are aligned and level, both top, and bottom.
• The hinge pins and blade are seized due to corrosion.
• The door gasket has been damaged and is preventing container door opening. Door gaskets are designed to present two or more fins against the structure or adjacent door. These are generally flexible but when the gasket is damaged, they may become hard or blocked thus jamming the door closed, or preventing it being closed.
• Water has become trapped between the doors and frozen, particularly relevant to refrigerated cargoes, or containers with moisture-releasing cargoes in cold weather.

 Doors that open but are stiff to move may suffer from the first two reasons above, along with possible misaligned hinge pins. Pins can become misaligned by damage to the ‘J-bar’ which has twisted one or more pins, or a hinge blade or pin has incorrectly aligned the blade with the hinges on the door.  Adding a backing plate under a single hinge blade may help take the blades out of alignment.  When a hinge blade needs to be refitted because of damage or corrosion and a doubler plate is required, plates should be inserted under all the blades on that door.

The safe operation of doors requires that some attention be given to them. Many hinges have coatings on the inner surface of the hinge blade, while others use plastic liners, both of which are designed to protect against corrosion. Some designs are fitted with greasing apertures. Fundamental to success are the examination and maintenance processes.

Typically, doors will be opened for in-service inspections and off-hires. Where oil does not free the hinges, repair work is probably necessary. An inspection is required to check that the hinges and hinge pin welds are not broken or cracked. Opening doors could be done when a depot releases a unit for packing, since it may have been in the stack for a prolonged period.

If the doors cannot be opened to pack a container, send the unit back! If it is already packed and you need to open the doors, but they will not open by hand, try to pull both doors open at the same time with increasing power. If you need more than two people, ensure you tell the container operator, especially if, as a result of container door opening, the locking gear or doors are or become damaged.

And, when you are opening a packed container, remember to watch out for those packages that are just about to fall out. In all these matters, be alert that the doors are big and heavy – treat them with respect and report anything unusual.

Injuries from Opening/Closing Hard-to-Open/Close Shipping Container Doors

On a freezing morning, when ice has seized a car door shut, one would never consider using a crowbar to open a car door.  The same thing goes for shipping containers.   While conditions may be more extreme in container operations, is it reasonable to use that kind of force to open or close container doors? Experience suggests that it is not, and often ends with someone being hurt.

Injuries to personnel involved with container door opening and closing are increasing, and often it is as a result of an inappropriate technique that is being employed. We might expect container doors to open and close as if they were car doors, without understanding why this might not be the case.

Starting with the structure of container doors, most will have four or five hinges per door. The mechanics at the point of manufacture is that the hinge pins must be all aligned on the same plane (vertical and horizontal) and in line. Offset hinge pins will result in the blade binding when it is rotated about the pin – the more the misalignment, the greater resistance will be encountered during operation. At the time of manufacture, therefore, it might be expected that the hinge pins on every door are aligned and free to fully open (270º of operation).

Let’s assume that the container is presented in pristine or well-maintained condition; why might the door not open with ease? Containers are generally either on a trailer/chassis or on the ground, and in both cases, the position of the locking gear handles are at an inconvenient height. For best results, the handles should be directly in front of you and at a height that is above the waist and below the shoulders.

The technique is all-important. Start with the two lock rods on the right-hand door, lift the handles out of the retainers and rotate them together as far as they will go. This should be more than 90º and rotation beyond 90º often initiates the container door opening process by forcing the cams out of their keepers. Then grasp the vertical locking bars, one in each hand, so that your hands are just below shoulder height and pull back with your body, using your leg muscles rather than your back.

If the door is still stuck, unless specifically advised against doing so (ie. the container is carrying a flexitank or bulk cargo), open the locking bars on the left-hand door and then grasp the inner locking rod of both doors and pull back, again using your body not your back. If the door still will not open, ask a colleague to pull on one door while you pull on the other.

Injuries almost always occur at the point frustration takes over and mechanical means are employed – the crowbar or a fork truck. So why will the door not open? Generally, this can be attributed to one of four reasons:

• The container frame is racked so that the door gear will not operate correctly. This may be caused by cargo shifting during transit. Look at the container to make sure that the doors are aligned and level, both top, and bottom.
• The hinge pins and blade are seized due to corrosion.
• The door gasket has been damaged and is preventing container door opening. Door gaskets are designed to present two or more fins against the structure or adjacent door. These are generally flexible but when the gasket is damaged, they may become hard or blocked thus jamming the door closed, or preventing it being closed.
• Water has become trapped between the doors and frozen, particularly relevant to refrigerated cargoes, or containers with moisture-releasing cargoes in cold weather.

 Doors that open but are stiff to move may suffer from the first two reasons above, along with possible misaligned hinge pins. Pins can become misaligned by damage to the ‘J-bar’ which has twisted one or more pins, or a hinge blade or pin has incorrectly aligned the blade with the hinges on the door.  Adding a backing plate under a single hinge blade may help take the blades out of alignment.  When a hinge blade needs to be refitted because of damage or corrosion and a doubler plate is required, plates should be inserted under all the blades on that door.

The safe operation of doors requires that some attention be given to them. Many hinges have coatings on the inner surface of the hinge blade, while others use plastic liners, both of which are designed to protect against corrosion. Some designs are fitted with greasing apertures. Fundamental to success are the examination and maintenance processes.

Typically, doors will be opened for in-service inspections and off-hires. Where oil does not free the hinges, repair work is probably necessary. An inspection is required to check that the hinges and hinge pin welds are not broken or cracked. Opening doors could be done when a depot releases a unit for packing, since it may have been in the stack for a prolonged period.

If the doors cannot be opened to pack a container, send the unit back! If it is already packed and you need to open the doors, but they will not open by hand, try to pull both doors open at the same time with increasing power. If you need more than two people, ensure you tell the container operator, especially if, as a result of container door opening, the locking gear or doors are or become damaged.

And, when you are opening a packed container, remember to watch out for those packages that are just about to fall out. In all these matters, be alert that the doors are big and heavy – treat them with respect and report anything unusual.
