How do you control an edge when protection is removed for delivery?

When collective edge protection is temporarily removed to move materials to an elevated work area, plan the smallest opening for the shortest controlled time, separate people from the drop, control the load, and restore and check the barrier before normal access returns. The unsafe moment starts when the protection comes off, not just during the lift.

The opening exists for minutes, but the fall risk starts at once

A delivery of boards reaches a partly built upper floor. The crew removes a run of guard rail to bring the load through the edge, the forklift arrives late, another trade works nearby and the open edge stays unguarded during lunch. By the time the load is placed, people treat the temporary gap as a normal route and no one has been named to put the rail back and check it. The unsafe moment is not only the lift, it starts when the collective protection is removed and continues until a suitable barrier is restored and the area is released. HSE's construction work-at-height guidance says work at height must be assessed, organised and planned so it is carried out safely, and the Work at Height Regulations 2005 require guard rails and similar collective protection to be suitable, strong, secured and placed to prevent people or objects falling. A delivery programme does not suspend those principles.

This guide owns a planned or discovered temporary opening at a floor, roof or work-platform edge for a material transfer. The scaffold alteration guide owns unauthorised scaffold component removal after handover, and the live hired plant handover guide owns suitability before plant first use. This page follows the open edge through authorisation, transfer, restoration and return to normal work.

Ask whether the barrier must be opened at all

Before removing collective protection, test the material route. Can the load be delivered through a permanent opening, an approved loading bay, a hoist, an internal stairwell or another designed method? Can smaller units be moved without creating a hazardous manual-handling task? Is there a suitable platform that allows unloading while keeping protection in place? Choose an option that controls the whole material movement, not just makes the lift convenient. If an opening is necessary, plan it with the principal contractor, the lifting or delivery team and the person responsible for the edge protection, and determine whether the barrier is a removable component in an approved design or part of a scaffold, temporary works system or permanent structure. Do not cut, unbolt or relocate a guard rail without understanding how the system is fixed and what it supports.

Specify the smallest practical opening and the shortest controlled duration, and identify who can remove and reinstate it, when the load will arrive and what conditions must be met before removal. If a lift is delayed, keep the protection in place until the transfer is ready, do not create a gap early in the morning to save minutes later, and identify where removed components will be stored so they stay intact and available for immediate restoration. Consider the load, plant and people below: the transfer may need a lifting plan, suitable lifting equipment, a competent operator and a landing area that can bear the load, and a barrier removed for one pallet does not authorise repeated lifts or a different vehicle.

Create a controlled zone before removal

Stop unrelated work in the affected zone and set a boundary back from the open edge that stops workers approaching the drop while the main guard rail is absent, accounting for the path of the incoming load, the operator's line of sight and the worker who will receive the material. Do not rely on a shouted warning to a busy workface; give the people who control access a clear instruction and stop authority. Protect the area below, because a board, fitting or tool can fall while the rail is removed and the load itself can swing, shift or be set down badly, establish a suitable exclusion for workers and the public, and where the opening is over an occupied area coordinate with the building operator and protect or close the space below. Do not assume a toe board left in place will prevent every object falling through a material opening.

Check access and escape for nearby work: the temporary boundary must not trap a crew or block an emergency route, and where workers normally use the edge as part of a walkway, provide and brief a safe alternative. Put signs and physical controls at every approach, since a person arriving from another stair or lift may not know the delivery is underway. Plan the personnel position during transfer, where the receiving team can stand, how the load will be guided without leaning beyond the edge, and whether a suitable loading gate, landing platform or mechanical aid is available, because "stay back" is not enough when the work itself requires someone to reach towards the drop. Ensure the opening and delivery teams communicate before the barrier moves; if several contractors share the floor and the sequence cannot be controlled, pause until one site lead can coordinate it.

Remove and manage the protection under the agreed method

Only the competent person identified in the method should remove the barrier components, using the system's instructions and the site's temporary works arrangements. The removal itself may expose the worker to a fall, so plan how they can work from a protected position, a suitable platform or an alternative sequence, a method that says "remove guard rail, then set up fall protection" leaves an unprotected first step. Keep removed rails, posts, fittings and toe boards identified and protected from damage, note the condition of fixings and sockets, and treat a corroded, bent or missing component as a restoration issue to solve before normal access resumes rather than substituting whatever is in the van.

Maintain the temporary boundary throughout the transfer. If the load is delayed, stop the task and consider replacing the guard rail rather than leaving the edge open; if weather worsens, visibility falls or wind affects the load, reassess. If the delivery passes through a scaffold loading bay, use its designed gate and load rating, HSE scaffold guidance says loading bays should have fall protection, preferably gates that can be moved safely for material placement, and this page is not permission to remove a scaffold rail as a substitute for a proper gate. If the protection is part of a designed temporary works system, record the temporary configuration and any design condition, and have the temporary works coordinator confirm the alteration, duration and reinstatement are covered by the method. HSE temporary works guidance. Do not assume a handrail is structurally irrelevant simply because it is labelled "edge protection."

Keep normal access closed until the barrier is restored

When the load is inside, secure it and clear loose material from the edge, then reinstate the barrier, posts, toe board and fixings according to the design or manufacturer's instructions and check the protection is continuous, properly connected and suitable, a rail hooked loosely into sockets may look complete from a distance but be displaced by a person leaning or moving a trolley. The person designated in the method should inspect the restored edge before the temporary exclusion is removed, checking the whole opening including adjacent panels, gates and the surface where the load landed, and where a designed scaffold or working platform was altered the applicable competent inspection and report process may be needed before normal use.

Record who restored and checked it, at what time, against which design or method and with what residual restriction, then have the site lead authorise return to ordinary access and brief the workers who were excluded. If a component is missing or the protection cannot be reinstated, maintain the exclusion and obtain a competent alternative, do not replace a collective system with a sign that says "take care." If the delivery continues on later days, redesign the arrangement as a repeatable controlled loading point, because repeatedly removing a fixed guard rail creates predictable gaps and unclear ownership; a suitable gate, hoist or platform may reduce both fall risk and disruption.

Deal with a gap discovered after the crew has left

Sometimes the site discovers the rail missing after the material team has gone. Treat it as an active unprotected edge: stop access, set physical exclusion and check whether anyone may be working below, then find out when the barrier was removed and whether other trades used the area during the gap. Do not send a general labourer to reinstall components unless they are competent for the system and the correction method is clear. Preserve the earlier record and photographs, an inspection completed before removal does not prove the current condition safe, and if a person was exposed or a material fell, use the site incident process and consider statutory reporting against the facts, without assuming that every temporary missing rail is automatically RIDDOR reportable.

Review the handover failure: was anyone named to close the opening, did the lifting crew assume the receiving crew would do it, did a break or shift change interrupt the task, or did a load exceed the planned opening so workers changed the method on the spot? These are system questions, and assigning blame without fixing ownership and the work sequence leaves the next delivery vulnerable to the same gap. If the area is accessible after hours, strengthen the temporary closure while repair is arranged, and have the next shift see a specific status and boundary rather than a rail lying nearby that suggests someone is about to replace it.

Where Complys can help

Complys publicly describes project documents, RAMS, inductions and work reports held together, which could hold the approved method, the assignment, the opening time, the restoration evidence and the affected-worker briefing. Complys does not detect an open edge, inspect a guard rail, calculate landing capacity or authorise a lifting operation automatically: a completed checklist cannot physically prevent a fall. The practical software test is whether the person opening the edge and the person restoring it share one current task and status; if they do not, use a visible physical control and direct handover, and keep design and return-to-use decisions with competent site personnel.
