Risk Assessment under ArGV 3 for Height Access Equipment: The Guide for Site Managers

Before the first scissor lift or articulated boom lift arrives on a construction site, one document needs to exist that many contractors underestimate: the risk assessment. It is not a formality, but under Article 3 of the Ordinance 3 to the Labour Act (ArGV 3) the legal precondition for using a piece of work equipment such as an aerial work platform or telehandler at all. Anyone who carries it out incorrectly, or not at all, is personally liable in the event of an incident – regardless of whether the rented equipment itself was technically flawless.

For site managers and safety officers, this raises a question with every enquiry to Luibl Rental that begins well before the choice of equipment: what hazards does the specific work site present, and what measures must be in place before the operator first steps onto the platform? This guide walks through the process step by step and shows how the assessment concretely shapes the choice of the right height access equipment.

ArGV 3 obliges the employer, or the site manager responsible on site, to identify and assess all associated hazards before a piece of work equipment is used for the first time. This explicitly applies to rented equipment as well: responsibility for assessing the specific work site remains with the operator – that is, the renting company – not with the rental provider. Luibl Rental supplies technically inspected, VUV-compliant equipment, but whether that equipment is suitable for the particular construction site, ground conditions and weather, must be assessed and documented by the operator itself.

This responsibility cannot be delegated without transferring it in writing. If a foreman or site supervisor is instructed to carry it out, that instruction must be documented just as thoroughly as the assessment itself. If the document is missing during an inspection by SUVA, the risk assessment is legally deemed not to have been carried out – even if work on the site was in fact carried out safely.

The legally required procedure follows a fixed pattern that can be made concrete for the use of aerial work platforms and telehandlers. First, all hazards that could arise at the planned work site are identified: the load-bearing capacity of the ground, possible wind loads in outdoor areas, proximity to overhead power lines, surrounding traffic areas, and any fall edges or floor openings. Only once this list is complete does the evaluation follow – that is, an assessment of how likely an incident is and how severe the possible consequences would be.

Based on this evaluation, the third step defines concrete measures. This is where the so-called TOP principle applies, setting out the hierarchy of permissible protective measures: technical measures before organisational measures before personal protective equipment. For an aerial work platform, this means in practice: first it is checked whether a technical solution, such as outrigger pads for load distribution or an automatic wind-sensor shutdown, can eliminate the hazard. Only if that is not sufficient do organisational measures follow, such as barriers and defined time windows for the work, and finally personal fall-protection equipment as the last line of safety for the operator.

In the fourth step, the defined measures are actually implemented and communicated to everyone involved – in particular the operator of the platform. The fifth, and often neglected, step is verifying effectiveness: only once it has been checked that the measures actually work in day-to-day site conditions is the process complete. If conditions change – for example because a second construction phase begins or the ground changes due to weather – the assessment must be updated.

The specific hazards differ considerably depending on the equipment used, which is why a blanket assessment without reference to the equipment is usually insufficient in practice. For scissor lifts used indoors, the main concerns are the floor load from the wheels' point loads and the ceiling height, whereas for diesel scissor lifts used outdoors, wind load, uneven ground and the need for outrigger pads also become relevant. Articulated boom lifts introduce a different hazard category due to their ability to reach sideways over obstacles: here the assessment must cover the entire swing range of the boom, including possible collisions with facade elements or cables.

Tracked aerial platforms are specifically used on rough or sensitive terrain, such as green spaces or historic flooring – here the risk assessment shifts more towards ground pressure and surface load. Truck-mounted platforms add a traffic-law component, since the set-up location on or next to public traffic areas brings additional obligations to secure the site. Anyone unsure which hazard category applies to their specific project can find the technical specifications of all platform types in Luibl Rental's aerial work platform category overview as a starting point for their own assessment.

The risk assessment does not stand in isolation; it forms the basis for two further obligations that are closely linked in practice. It directly determines what qualification the operator must hold: for example, if the assessment establishes that an articulated boom lift with a high degree of swing dynamics will be used, it must be ensured that the assigned operator holds the appropriate IPAF category. Details on the individual categories and the requirement for written authorisation are summarised in the guide to the IPAF operator card.

The risk assessment is likewise linked to the technical inspection of the equipment, but does not replace it: inspection under VUV establishes that the machine itself is safe, while the risk assessment evaluates whether using it at the specific location under the specific conditions is safe. Both documents are requested independently of one another during an inspection. How inspection documentation is organised at Luibl Rental, and which records must be available on the equipment, is explained in detail in the guide to inspection under VUV.

A risk assessment carried out verbally has no evidentiary value in court or during SUVA inspections. The record must include the work site and time period, the hazards identified, the measures defined under the TOP principle, the responsible person, and the date of the effectiveness check. The document is signed by the person who carried out the assessment – generally the site manager or a specialist formally instructed by them in writing.

The retention obligation is based on the length of time the work equipment is used, but at least until the relevant construction phase is completed. For recurring, comparable operations – for example, when the same scissor lift is regularly used in the same factory hall – an existing assessment can serve as a template, but it must be reviewed and updated again whenever the underlying conditions change significantly.

To make it easier for site managers to get started, Luibl Rental provides a compact checklist that summarises all the relevant checkpoints for using aerial work platforms and telehandlers in the correct order – from assessing the ground to wind-load limits and a documentation template based on the TOP principle. The checklist does not replace an individual on-site assessment, but it provides a solid structure that helps even site managers without daily safety-specialist routine avoid overlooking any relevant checkpoint.

Once the risk assessment is complete, it is usually also clear which equipment category meets the requirements: an electric scissor lift for dust-free indoor use, an articulated boom lift for work over obstacles, or a tracked platform for sensitive outdoor surfaces. Luibl Rental delivers the right equipment across Europe, including a valid VUV inspection sticker, and provides support with any questions about equipment selection so that the technical measures defined in the assessment can actually be implemented. Anyone who additionally needs operator training will find suitable IPAF and system-card courses for all equipment categories in Luibl Rental's training programme.

Do I really need to carry out a risk assessment myself for a rented piece of equipment? Yes. Responsibility for the risk assessment lies with the operator – that is, the renting company – regardless of whether the equipment was purchased or rented. Luibl Rental provides technically inspected equipment; assessing the specific work site remains the responsibility of the site manager.

Is a general risk assessment sufficient for all construction sites? No. Since ground conditions, weather and surrounding conditions differ from site to site, the assessment must be reviewed for each new work site and adjusted whenever there are significant deviations.

What happens if no risk assessment is available during an inspection? If the document is missing, the assessment is legally deemed not to have been carried out. This can lead to fines, an immediate work stoppage, and, in the event of an incident, personal liability for the responsible person.

How does the risk assessment differ from inspection under VUV? Inspection under VUV confirms that the equipment itself is technically safe. The risk assessment evaluates whether using this equipment at the specific location under the specific conditions is safe. Both records are required independently of one another.

Who is allowed to carry out the risk assessment? In principle, the employer itself, or a formally instructed, competent person, such as a site manager or safety specialist. The instruction must be documented.
