Common MEWP Accidents and How to Prevent Them

Working at height accidents remain one of the leading causes of serious injury across construction, facilities management and industrial environments. Mobile Elevating Work Platforms (MEWPs) are designed to improve safety and access, but incidents still occur when equipment is misused, poorly planned or operated without the right level of competence.

Understanding how a typical accident working at height happens, and how it can be prevented, is essential for anyone responsible for site safety, plant hire, or powered access operations. Below, we explore the most common MEWP-related accidents and the practical steps that reduce risk on site.

Why MEWP Accidents Still Happen

MEWPs are widely recognised as a safer alternative to ladders and scaffolding for many tasks, yet working at height accidents involving powered access equipment continue to be reported every year. In most cases, incidents are not caused by equipment failure. They are linked to human factors, planning gaps or site conditions that were not properly assessed.

Common contributing issues include inadequate operator training, unsuitable machine selection, poor ground conditions and pressure to complete work quickly. Addressing these risks early is key to preventing an accident working at height before it occurs.

The Most Common Causes of Accidents and How to Prevent Them

Falls from the Platform

Falls remain one of the most serious working at height accidents involving MEWPs. These incidents can occur when operators climb on guardrails, overreach beyond the platform, or fail to use harnesses where required.

How to prevent it:

• Ensure operators are trained to understand platform limitations and safe working practices.
• Use appropriate fall protection equipment when specified by the manufacturer or site risk assessment.
• Avoid leaning or climbing on rails to gain extra reach.
• Select a MEWP with adequate outreach and platform height for the task.

IPAF training places strong emphasis on safe platform behaviour, helping operators recognise situations that commonly lead to falls.

MEWP Overturning and Tip-Overs

Overturning is another major cause of incidents working at height. These events often result from uneven ground, steep gradients, poor use of outriggers or operating the machine outside its rated capacity.

Tracked booms and other specialist MEWPs are particularly sensitive to ground conditions because their operational stability relies heavily on the ground’s ability to support high-point loads.

How to prevent it:

• Carry out a detailed assessment before delivery.
• Check ground bearing capacity and identify slopes or voids.
• Use spreader plates and outriggers as required.
• Never exceed platform load limits.
• Follow manufacturer guidance for safe operation on gradients.

Correct machine selection and proper familiarisation significantly reduce overturning risk.

Entrapment and Crushing Incidents

Entrapment occurs when an operator becomes trapped between the platform and a fixed structure, often when working close to ceilings, steelwork or overhead obstructions. These working at height accidents can be severe and sometimes fatal.

They frequently happen when operators lose situational awareness or attempt to reposition the platform in confined spaces.

How to prevent it:

• Use MEWPs fitted with secondary guarding where appropriate.
• Maintain clear communication with ground staff.
• Move slowly when operating near obstructions.
• Stop work immediately if visibility is compromised.

Training helps operators understand blind spots, control sensitivity and the importance of controlled movements.

Collisions with Structures or Vehicles

MEWP collisions can occur at ground level or while elevated. Contact with buildings, racking, services or moving vehicles can destabilise the machine and cause injuries to operators or others on site.

How to prevent it:

• Segregate MEWP operating zones from pedestrian and vehicle traffic.
• Establish clear exclusion zones.
  • Use banksmen when visibility is limited.
• Plan access routes in advance, especially on busy sites.

Many accidents working at height involve poor traffic management rather than equipment faults.

Electrical Contact and Overhead Hazards

Contact with overhead power lines or live electrical services is a serious risk when operating boom lifts and other outreach machines. Even indirect contact can cause severe injury or fatality.

How to prevent it:

• Identify overhead hazards during site planning.
• Maintain safe clearance distances from live services.
• Use insulated MEWPs where required.
• De-energise services when possible.

Operator awareness and supervisor oversight are critical in preventing electrical-related working at height accidents.

Inadequate Training and Competence

A lack of training underpins many MEWP-related incidents. Operators without formal instruction may not fully understand load limits, emergency lowering procedures or how site conditions affect stability.

An accident working at height is far more likely when operators are unfamiliar with the specific category of MEWP they are using.

How to prevent it:

• Ensure operators hold valid IPAF certification for the correct MEWP category.
• Refresh training before PAL cards expire.
• Provide familiarisation when introducing new or unfamiliar machines.
• Ensure managers and supervisors understand their responsibilities.

Competence applies to planners and supervisors as well as operators.

Poor Pre-Use Checks and Maintenance Issues

Skipping daily checks or operating damaged equipment increases the risk of mechanical failure and unsafe operation. While MEWPs are robust, faults can develop if inspections are missed.

How to prevent it:

• Complete documented pre-use inspections before every shift.
• Report faults immediately and remove machines from service if required.
• Use well-maintained equipment from reputable providers.
• Never bypass safety systems or alarms.

A structured inspection process reduces avoidable working at height accidents caused by overlooked defects.

The Role of Planning and Risk Assessment

Many accidents occur because tasks are not properly planned. Rushed decisions, unsuitable equipment and unclear responsibilities create conditions where errors are more likely. Effective planning includes:

• Selecting the correct MEWP for height, reach and environment.
• Considering ground conditions, access and overhead hazards.
• Coordinating MEWP use with other site activities.
• Reviewing weather conditions, particularly wind exposure.

Strong planning significantly lowers the chance of an accident working at height.

Most MEWP-related incidents are preventable. By understanding how working at height accidents happen and addressing the root causes, businesses can protect people, projects and productivity. The right training, correct equipment and clear planning all play a role in preventing an accident working at height. With a safety-first approach and experienced support, MEWPs remain one of the safest and most effective ways to work at height.
