A roofing sheet line starts with something very heavy and ends with something very sharp. At the front, a colour-coated coil is lifted off a truck, carried by crane and lowered onto the decoiler mandrel. At the back, the shear drops and a profiled sheet slides onto the stacking table, its cut edge as keen as a blade. People work close to both.
The roofing material makers page puts coils and edges at the head of its strains. Owners tend to file this under machinery. The risk is really about who handles the coil, who coached them and whether anyone inspects the tackle.
Where people get hurt on a sheet line
- Coil unloading. A coil slips from a C-hook or a single sling, or rolls on the floor because nobody placed chocks.
- Strap cutting. Steel strapping under tension whips back when cut from the wrong side.
- Threading the decoiler. Hands near the coil end and the first roll stand while the operator jogs the line.
- Nip points. Gloves or sleeves caught where the strip enters the forming rolls.
- The shear and run-out. Clearing a jammed sheet by hand while the shear is still live.
- Stacking and bundling. Sliding long sheets by hand, edge-first, with bare forearms. This is where most cuts happen.
- Loading trucks. Bundles shifting on the forklift, and helpers walking under a suspended load.
Why rules differ from shift to shift
Most roofing units grow fast from a single line. The first crane operator trained the next by example. Sling checks happen when the day supervisor remembers. On the night shift, whoever is free hooks the coil. Hardly any unit keeps a roll of approved lifters.
Gloves tell a similar tale. Cut-resistant gloves are bought, but they are hot and they slip on the protective film, so stackers take them off. Arm sleeves are not issued at all. The supervisor who insists one week gives up the next when a dealer's truck is waiting.
Turnover makes it worse. Stackers and loaders are often new, paid daily, and put on the table on their first morning. They copy whoever stands next to them, including the shortcuts.
Making coil and sheet handling a named job
- 1
Name the crane and sling crew
Write down who may operate the crane, who may sling a coil and who may cut straps, for each shift. Anyone not on the list stays clear of a coil lift.
- 2
Check gear before the first lift
C-hook or coil tongs, slings, shackles and chocks inspected by a named person, with damaged tackle tagged and taken out of use.
- 3
Set a coil handling sequence
Unload, chock, cut straps from the safe side, lift to the decoiler, secure the coil end. Write it in plain steps at the decoiler.
- 4
Issue and enforce hand and arm protection
Cut-resistant gloves that grip film, arm sleeves for the stacking table, and a supervisor who looks at every stacker's hands before each run.
- 5
Isolate before clearing jams
Agree a simple rule that the shear and forming rolls are stopped and locked before any hand enters, and train every operator on it.
- 6
Give the supervisor stop authority
The shift supervisor holds written power to halt the line when lifting rules are skipped, without needing the owner's approval.
Who may lift, who may stop the line and who checks the gear should be part of the written duties for each post. The roofing role descriptions page sets out those duties so they survive a change of supervisor.
A shift-start lifting and line check
Date, shift and line number.
Crane operator and authorised slingers on duty.
C-hook or tongs, slings, shackles: checked, any withdrawn.
Chocks and coil saddles in place at the unloading bay.
Shear and roll stand guards fitted and working.
Lock-out point for the shear tested.
Gloves and arm sleeves issued to every stacker and loader.
New joiners on shift and who inducted them.
Supervisor signature.Keep the check at the decoiler, not in the office. Go through it at the shift huddle. Within a month the sheets reveal which shifts skip items and which slings fray first. The wider safety routine for a sheet plant, including near-miss reporting, is covered under roofing health and safety.
First morning for stackers and loaders
Every new hand should spend their first hour learning the line before touching a sheet. Where to stand during a coil lift. How to hold a sheet by its face, two people per long sheet. Where the stop buttons are. What to do with a jammed sheet: shout for the operator and keep hands out. The roofing onboarding steps cover the same induction for fixers who go to roofs, where the risk moves to the edge of a building.
Crane operators and slingers need more than a first morning. A staged route, with practical assessment on your own coils and a refresher at fixed intervals, belongs in the learning and development route for roofing units. Paying authorised slingers a small allowance keeps the role filled by people who take it seriously.
A walk down the line this week
- Ask the night shift who slung the last coil, and whether that person is on any list.
- Pick up a sling and a C-hook and see whether anyone can say when they were checked.
- Watch the stacking table for ten minutes and count bare forearms.
- Ask the newest loader who showed him the line on his first day.
- Check whether the supervisor has ever stopped the line for a lifting shortcut, and what happened next.
Coil handling, wrong-length runs, scarce roll-set fitters and untrained roof fixers make up the core people risks here. The HR overview for building material plants links them up.
