Dismantling and handling components

Dismantling is not just 'erection in reverse at high speed'. Guardrails and decks are removed while work is still being done at height, and the temptation to hurry is great. Plan the dismantling and set aside time — most scaffolding accidents during assembly happen when someone is in too much of a hurry.

Haste is the most dangerous component on site — plan dismantling as a task, not a tidy-up.

Cordon off the area under the dismantling zone so that no unauthorised persons pass through. During dismantling, loose components are handled at height and there is an increased risk of falling objects — the cordon protects those below.

BEK nr. 2107/2021 requires collective fall protection during ALL dismantling — not just erection. Keep the guardrail in place for as long as possible, and use personal fall protection (harness/lanyard) as a supplement in the transitional phases where approved collective equipment cannot be in place.

Dismantle the scaffold in the reverse order of erection, following the supplier's instructions: top first, and the anchors are removed as the height is reduced — not before. Deviating from the sequence requires a professional assessment, because the stability changes along the way.

Never remove anchors ahead of the dismantling — an unanchored scaffold that is still tall can topple.

The guardrail is the primary collective fall protection during access to the top lift being dismantled. So remove it as late as possible at each level — only when you no longer need to stand protected on that deck.

Lower the components in a controlled way — hand to hand, by hoist or via a fall-protected chute. NEVER throw materials down; a tube or deck in free fall is lethal and also destroys the component.

Nothing is thrown down. A falling scaffold tube hits harder than most people think.

Dismantling is a good opportunity for a rejection assessment: separate components with rust perforation, cracks or deformation from the usable ones (DS/EN 12811-2). A component that has been damaged during the period of use must be taken out of circulation now — not put up again next time.

Clean and sort the components before returning or storing them, and store them dry so they do not rust. Sorted, clean equipment makes the next goods-in inspection quicker and extends the components' service life.

Close the job in the QA log: note the dismantling date, the responsible person and any rejected items. The documentation trail is closed when the scaffold is down — not only when the equipment is back in the yard.
