What You Need to Know
Aerial work platforms are indispensable in the construction and industrial sectors. They enable safe work at height and offer significantly more flexibility than conventional scaffolding or ladders. At the same time, the risk of serious accidents increases with working height. Falls and being thrown from the work basket are among the most frequent causes of accidents – accordingly, legal requirements for fall protection are very strict.
A key question is therefore: When is the use of personal protective equipment against falls from height ( PPE against falls from height) mandatory? While a surrounding guardrail is considered sufficient protection for certain work platforms, the use of a safety harness is mandatory for other types of platforms.
Crucial factors include not only the working height, but above all the design, the type of movement of the platform, the operating environment, and the risk assessment. The DGUV Principle 308-008 "Qualification and Appointment of Operators of Mobile Elevating Work Platforms" is particularly relevant here.
From what height is personal protective equipment against falls from height (PPEgA) mandatory on a mobile elevating work platform?
There is no fixed height requirement. Contrary to popular belief, the obligation to use personal protective equipment against falls from height (PPEgA) does not primarily arise from the height , but from the question of whether a fall or being thrown from the work platform can be reliably prevented from a technical standpoint.
For scissor lifts with a fixed, surrounding guardrail, seatbelt use is generally not required. The guardrail acts as a collective safety measure and reliably prevents falls from the work basket.
The situation is different with telescopic, articulated, and truck-mounted aerial work platforms . Lifting, slewing, and driving movements generate dynamic forces that can lead to jerky movements during abrupt stops or on uneven ground. Without safety measures, there is a real risk of operators being thrown from the work platform.
The work location also plays an important role. Working over water, machinery, traffic areas, or at edges where there is a risk of falling can trigger a requirement to wear a harness – regardless of the type of platform used.
Protection against being ejected from the work basket
A common misconception is that fall protection only prevents direct falls. In practice , being ejected from the work basket is one of the greatest dangers on mobile elevating work platforms.
Causes include: uneven ground, sudden braking, driving in an elevated position, or collisions with obstacles.
For this reason, DGUV principle 308-008 generally requires the use of PPE against falls from a height with a suitable restraint or safety system for many mobile elevating work platforms.
The anchor point must be provided by the manufacturer and may be located no more than 750 mm above the floor of the work platform . Anchor points located higher increase the potential fall height and are not permitted.
The lanyard used must not exceed 1.8 m in length. Longer lanyards increase the risk of pendulum falls and dangerously high impact forces.
Restraint system or containment system – which is correct?
The DGUV (German Social Accident Insurance) clearly recommends: Restraint systems take precedence over fall arrest systems. They prevent the operator from even being able to move into a fall hazard area.
Restraint systems use very short connecting elements (approx. 0.3–0.5 m) and practically eliminate the possibility of a free fall. The risk to people and equipment is minimal.
Fall arrest systems allow a fall to occur and only then arrest it. They should only be used when restraint systems are technically impossible.
Many mobile elevating work platforms (MEWPs) require or mandate the use of a fall arrest device (CAD) – especially when moving the platform. CADs reduce impact forces and automatically adapt to the dynamics of movement.
What must be considered when using personal protective equipment against falls from height (PPEgA) on mobile elevating work platforms?
A safety harness only provides reliable protection if it is used correctly. Crucial factors include: the correct anchor point, the correct length of the lanyard, the appropriate system, and the equipment being in perfect working order.
Personal protective equipment against falls from a height (PPEgA) must be visually inspected before each use. Damaged straps, carabiners, or connectors must not be used and must be discarded immediately.
When is PPE against falls required?
The DGUV principle 308-008 clearly stipulates: Only instructed and authorized persons may operate mobile elevating work platforms using PPE against falls from height.
Personal protective equipment against falls from height (PPEgA) is required:
- before the first use of mobile elevating work platforms,
- when using PSAgA,
- in case of special hazards (e.g. traffic, water, machinery),
- at least once a year as a refresher course.
The training must cover both theoretical and practical content. This includes, among other things: recognizing hazards, differentiating systems, correctly donning and attaching personal protective equipment against falls from height (PPEgA), as well as emergency and rescue measures.
Which helmet is required when using PPE against falls from height?
When using personal protective equipment against falls from height (PPEgA), a conventional construction helmet is insufficient. An industrial safety helmet with a chin strap conforming to EN 12492 is required.
These helmets stay securely on the head even during sudden movements, protect against pendulum motions and offer additional support in the event of a possible impact.
Don't underestimate the whiplash effect (catapult effect).
Rapid slewing movements or abrupt stops can cause the so-called whiplash effect on aerial work platforms. This results in enormous acceleration forces acting on the operator, which, without correctly used personal protective equipment against falls from height (PPEgA), can lead to ejection. This is precisely why proper fall protection is mandatory for certain types of platforms.
Conclusion: Seatbelt use is not a formality
The obligation to use fall protection on mobile elevating work platforms (MEWPs) does not arise from a fixed height, but rather from the platform's design, movement dynamics, and operating environment. DGUV Principle 308-008 provides the binding framework for this.
Correctly used PPE against falls from height, permissible anchor points (≤ 750 mm), limited connecting devices (≤ 1.8 m) and regular training are crucial for safety on stage.
