Advanced Formliners weekly toolbox talk
Setting and stripping a liner safely
Safety talk. 7 minutes. Published September 8, 2026.
The hazard
A liner sheet is heavy and floppy, and it has a hard edge. Almost every injury it causes happens in the same few seconds: the moment it seats against a bulkhead or a side rail, and the moment it lets go of a cured panel. Both times, something moves faster than the person holding it.
The four we see most are a hand caught between the sheet and the bulkhead, a knife cut while trimming, a slice from the edge of a sheet that was trimmed and left sharp, and a strained back from carrying a rolled sheet with two people at different heights.
Setting the sheet
Agree on who calls the lift before anyone bends down. One voice, and the other person moves on that voice. Carry a rolled sheet with both people on the same side and the same height, or put it on a cart.
Hands stay on the top edge of a sheet that is being lowered, never underneath it. When the edge has to seat tight against a bulkhead, seat it with a bar or a length of stock, not with a hand in the gap. The gap between a liner edge and a steel side rail closes to nothing, and it closes without warning.
Trim on a bench, not in the bed. A fresh blade cuts with less force than a dull one, which is why a dull blade causes more cuts than a sharp one. Cut away from the body, and put the offcut and the used blade in the bin before the next sheet goes down. A trimmed liner edge stays sharp for the life of the sheet, so anyone reaching into that run later is reaching past it.
Gloves are chosen for the hazard, not for habit. Cut-resistant gloves for the knife work, and whatever the release agent SDS calls for once the sprayer comes out. Our written PPE assessment is what settles that, and it is worth reading again if nobody in this crew has looked at it this year.
Stripping
The liner is stuck to the panel by draft and by suction, and it releases all at once. That is the part that catches people.
Break the first corner with a pry bar or a wedge, standing so that the sheet cannot come back at you. Keep fingers out from under an edge that is about to go. Once the first corner is loose, work along the edge and let the draft do the pulling. Fighting the draft chips the liner and tears the panel face, and it puts a lot of load on one person’s grip.
A sheet that comes loose suddenly can whip. Give it room, and give the person on the other end of it room too.
The lift itself
There is no OSHA number that tells you the heaviest thing a person may pick up in a plant. That is set by our own written program and by the job. What is true everywhere is that a lift close to the body, at waist height, with a good grip and no twisting, is the one that does not hurt anyone. If the sheet is not that lift, break it down, get a second person, or put it on the hoist.
Discussion questions
- 01 Where on our bed does a hand get caught first when a sheet seats against the bulkhead?
- 02 When two of us move a sheet, who calls the lift, and did we agree on that before we picked it up?
- 03 Are the gloves we have on right now the ones our PPE assessment calls for on this task?
- 04 When a corner will not release, what do we reach for before we reach for our fingers?
- 05 What did we trim in the bed last week that we could have trimmed on the bench?
Takeaways
- One person calls every two-person liner lift, out loud, before it moves.
- Break the first corner with a bar. Never with fingers under the edge.
- Trim on a bench with a fresh blade, cutting away from the body.
- Offcuts and blades go in the bin before the next sheet goes down.

This talk is a starting point for a plant's own safety program. It does not replace that program, the plant's written procedures, or the safety data sheets for the products in use. Have your safety lead review it against your own procedures before you read it to a crew, and use your own numbers wherever a limit, a weight, an interval, or a control is involved.
