Magic Glasses: Drop Zones and Suspended Loads
- Mar 2
- 3 min read
When a load is on the hook, it can look steady and controlled. When you put on the Magic Glasses, you stop watching how smooth the lift is and start looking at the space beneath it. That space is where the risk sits.
Quick Scene-Setter
A tower crane is lifting a power trowel up to the top floor of a building under construction.
Concrete is being pumped.
The site is active.
The load is travelling to where it is needed.
Dogman is grabbing the tag line
It looks routine.
What Most People See
Most people see:
A small piece of equipment
A short-duration lift
A controlled crane
A clear landing area
Dogman doing his job
They assume:
“It is only equipment.”
“It is not a major lift.”
“It will be up there quickly.”
“The dogman knows the load.”
The attention stays on where it is going.
What the Magic Glasses Show You
1. It Is a Suspended Load
While it is:
On the hook
Under tension
Travelling through the site
It is a suspended load.
If something fails, it falls.
There is no recovery time.
2. The Drop Zone Is Directly Beneath It
The drop zone is not complicated.
It is:
The area directly under the load
The swing path
The space the load travels across
If someone stands there, they are exposed.
3. The Drop Zone Moves
As the crane slews:
The hazard shifts across the site.
The exposed area changes.
That is why it must be actively controlled.
4. Small Loads Create Casual Behaviour
Because it is “only” equipment:
People continue working beneath it.
No clear exclusion is set.
Workers walk through the area without thinking.
Routine lifts are where discipline drops.
The Law Is Clear
The Health and Safety at Work (General Risk and Workplace Management) Regulations require that, so far as is reasonably practicable, no person is beneath a suspended load.
That is not guidance.
If the load is on the hook and someone is standing under it, the requirement is not being met.
👉 Critical Point: You can’t stand under a suspended load. Not even to grab a tag line.
The Controls That Matter
Identify the lift path before the hook moves.
Establish a visible exclusion zone beneath the load.
Stop non-essential work within that zone.
Assign someone to control and enforce it.
Keep the space clear until the load is landed and de-tensioned.
Control the space.
Do not rely on confidence.
Magic Glasses Checklist – Drop Zones
Before lifting:
Who may end up beneath the hook?
Has the exclusion zone been set?
Is someone enforcing it?
Are people casually walking through the area?
Is the load fully supported before tension is released?
If people are under the load, the lift is not controlled.
It does not matter what is on the hook.
What matters is who is underneath it.
A suspended load is safe only when the space beneath it is controlled.
That is what the Magic Glasses show you.
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.
