Magic Glasses: Hooking Containers Without Climbing

At first glance, a container lift can look organised and under control. Put on the Magic Glasses, and you start to notice when someone is being placed in a position where risk cannot be reduced, even before the lift itself has started.
Quick Scene-Setter
A Hiab is set up to lift a shipping container.
The container is rigged from the top using short strops.
A worker climbs onto the container roof to connect the rigging and operate the Hiab by remote.
The container is not lifted while the worker is on top.
From a distance, it still looks routine.
What Most People See
The container is not being lifted while the worker is on top.
The worker is experienced and appears confident.
The remote gives good control.
The task looks calm and deliberate.
Because the lift has not started, the risk feels low.
What the Magic Glasses Show You
The worker is already in an unsafe operating position
Even without lifting the container, the worker is:
At height
On an unprotected surface
Without edge protection or fall restraint
With no safe place to move to
The risk exists before the lift

No ability to move to a safe position
From the top of the container:
There is nowhere safer to step back to
There is no protected stance to operate from
If footing is lost, there is no recovery option
Once up there, exposure is fixed.
Remote operation adds risk during rigging and movement
While rigging and operating the Hiab by remote from the container roof:
Attention is split between balance and crane control
Focus is on footing rather than the task
There is no separation from the load or hook block
This is not a stable or controlled operating environment.

Access and egress are high-risk moments
Getting onto and off the container introduces additional hazards:
No designed access system
Increased slip and misstep risk
Elevated likelihood of a fall during transition, not during the lift
These moments are often where incidents occur.
Risk of unintended crane movement
With a live remote at height:
Buttons can be bumped
Controls can be activated unintentionally
Crane movement can occur when the worker is least stable
This risk exists even if the lift is not underway.

Wide sling angles still matter
Short rigging attached at the top of the container creates wide sling angles.
In the image, the included angle exceeds 120 degrees, increasing rigging tension and reducing effective working load limits.
This is a separate issue, but it reinforces the idea that poor lift geometry is accepted as normal. When the chains are clearly overloaded, they may fail on a future lift, if not this one.
The common thread: unnecessary exposure
None of these risks are required to rig a container:
Rigging can be done from the ground
Sling angles can be controlled with longer gear
Container lifters can remove the need for climbing entirely
The worker is exposed because of the method, not the task.
The Controls That Matter
Complete all rigging from ground level using long gear.
Use container lifters or rated container hooks designed for container handling.
Control the sling geometry so that the included angles remain within the rated limits.
Operate Hiab remotes from a stable, safe position on the ground.
Ensure remotes are isolated during access and egress.
Establish the exclusion zone before rigging begins.
Ask early whether a side loader or swing lift would eliminate rigging and height exposure altogether.
Stop the job if climbing onto the container is being treated as normal.

Magic Glasses Checklist – Container Rigging
Is anyone required to climb onto the container?
Can all rigging be completed from ground level?
Does the operator have a safe, stable operating position?
Are sling angles within rated limits?
Is the remote isolated during access and movement?
Is a Hiab the right tool for this container move?
Would a side loader or a swing lift reduce the risk more? (While these tools don't always fit, we need to consider them as they reduce the risk.)
The container does not need to be lifted for the risk to exist. Once someone is on top of a container with a live remote, they have no safe place to go and no margin for error.
The Magic Glasses help you see that this is not about whether a lift is happening yet. It is about placing someone in a position where risk cannot be reduced.
Stay on the ground, control the geometry, and choose methods that remove the hazard entirely.
Magic Glasses: The magic glasses come from the reality of - when I look at my books, I don't see a problem. But when my accountant looks at the books, it's a whole different story. He must have a special set of glasses.
As PCBU's, Officers and Workers, we have an obligation to learn what we are up to and the risks. Our actions and the standards we accept also affect those around us. This magic glasses post is made to help others see what we see.
