Why this matters
Use this leader guide before glass rack & a-frame securement work to review the real setup, the controls that need to be in place, and the conditions that should stop the task. Material handling becomes dangerous when the load blocks vision, shifts unexpectedly, exceeds the planned handling method or is stored where it can roll, fall or trap someone. Plan the route, grip, team/lifting aid and final storage before the material starts moving.
A scenario to discuss
The crew starts Glass Rack & A-Frame Securement with a clear route, then a doorway, stair, delivery, occupied area, or another trade changes the path. The load is already picked up. Where should it be set down, and what route/control should be reset before moving again?
Before work starts
- Confirm load weight/shape and select the lifting aid, cart, team size or handling method before moving it.
- Walk the route and remove trip hazards, protect finished surfaces and control doors/traffic.
- Prepare stable storage/landing space before the load leaves its starting point.
- Set racks/A-frames on level, capable surfaces and secure them against movement or vehicle impact.
- Use rated restraints so sheets cannot fan, slide or tip when one lite is removed.
Common failure points
- Starting the move before there is a clear destination and route.
- Handling a load that blocks vision or shifts without enough people or a mechanical aid.
- Stacking material where it can roll, tip, slide or obstruct emergency/access routes.
Safe work sequence / controls
- Set racks/A-frames on level, capable surfaces and secure them against movement or vehicle impact.
- Use rated restraints so sheets cannot fan, slide or tip when one lite is removed.
- Load/unload from the intended side and maintain balance on the rack as the stack changes.
- Keep workers out of the potential tip/fall zone when restraints are released.
Stop and reset the plan if...
- The load weight, route, center of gravity or handling method is uncertain.
- Storage, racks, cribbing, carts or landing areas are unstable, overloaded or blocked.
- The crew cannot maintain visibility, communication or clear hand/foot placement during the move.
Questions worth asking the crew
- What does this load weigh, where is its center of gravity/awkward side, and what does that mean for the number of people or equipment we need?
- What route are we using, and where will vision, footing, doors, stairs, traffic, or other workers make the move harder?
- Who is calling the move, and what lifting aid/cart/team method are we using instead of trying to muscle through a bad position?
- Where will the material be set down or stored so it cannot roll, tip, slide, blow over, or block access?
- Has anyone had a load shift, block vision or become harder to carry than expected? Where is the safest set-down point on this job?
Make it real on the job
Walk the move from pickup to set-down and identify the pinch points and where vision will be blocked.
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.
