Why this matters
Take a few minutes before the task to cover Decking Installation Hazards. The main concern is wind, unsecured decking and fall exposures, so make sure everyone sees the exposure and knows the plan before work begins. A lift can look controlled until the load shifts, the radius changes, the ground settles or communication breaks down. Nobody should be guessing about load weight, rigging, travel path, exclusion zones or who is giving the signal.
A scenario to discuss
During Decking Installation Hazards, the load begins to rotate or hang differently than expected. A worker moves closer to steady it by hand while the operator is still holding the load. What is the safer reset before the lift continues?
Before work starts
- Confirm load weight, pick points/center of gravity, equipment capacity and rigging configuration before the lift.
- Inspect rigging, hooks, hardware and lifting equipment and remove questionable components from service.
- Walk the load path, landing area and exclusion zone and assign the signal/spotter roles.
- Confirm the erection sequence, temporary stability and connection requirements before releasing a member from the crane.
- Keep workers outside the swing and suspended-load zone unless their task requires controlled access.
Common failure points
- Starting before the load weight/center of gravity and capacity at radius are understood.
- Allowing people into the fall zone or swing radius because the load “is only moving a little.”
- Continuing after communication, ground support, rigging condition or load control changes.
Safe work sequence / controls
- Confirm the erection sequence, temporary stability and connection requirements before releasing a member from the crane.
- Keep workers outside the swing and suspended-load zone unless their task requires controlled access.
- Use the required fall protection and protect deck/opening hazards as steel and decking progress.
- Inspect rigging, connectors and tools before use and secure tools against dropping when needed.
Stop and reset the plan if...
- Load weight, center of gravity, rigging configuration or equipment capacity is unknown or different from the plan.
- Ground, outrigger support, wind, visibility or communication conditions are not acceptable.
- A worker enters the fall zone, pinch zone or swing radius without the lift being stopped and controlled.
Questions worth asking the crew
- What is the load weight/configuration, and how do we know the equipment, rigging, and attachment points are within capacity?
- Where are the fall zone, swing radius, and pinch/crush areas, and how will people be kept out for the entire lift?
- Who is giving signals, what communication method are we using, and what happens the instant communication is lost?
- What change in ground, wind, rigging, load control, or travel path would make us set the load down and re-plan?
- Has anyone seen a load shift, rigging change or signal break down during a lift? What should trigger an immediate set-down here?
Make it real on the job
Point out the fall zone, rigging connection and signal person before the load leaves the ground.
Close the talk
Before the crew starts, everyone should be able to explain the hazard, point to the control being used today, and name the condition that would make the work stop.
