MEWP Risk Assessment: What It Covers

If you’ve ever looked up at someone working on a scissor lift or boom lift and thought, “That looks risky”, you’re right to think so. Mobile Elevating Work Platforms (MEWPs) are indispensable tools on construction sites, warehouses, telecom maintenance, and even window cleaning jobs—but they also present serious hazards if not handled with caution.

That’s why a MEWP Risk Assessment isn’t just a paperwork exercise—it’s a life-saving process. Skipping or underestimating this step can lead to fatal falls, tip-overs, electrocutions, and costly compliance penalties.

In this guide, we are diving deep into what a MEWP Risk Assessment truly covers, why it’s essential, and how you can perform one properly. If you’re an HSE manager, safety consultant, project engineer, or even an operator, stick around. You’ll walk away with actionable insights that could save lives and reduce liability.

What Is a MEWP Risk Assessment?

At its core, a MEWP Risk Assessment is a structured evaluation that identifies hazards associated with the use of Mobile Elevating Work Platforms (MEWPs) and outlines control measures to mitigate those risks. MEWPs include equipment such as boom lifts, scissor lifts, cherry pickers, and aerial work platforms.

According to the UK Health and Safety Executive (HSE) and OSHA (Occupational Safety and Health Administration) in the U.S., a risk assessment is required before any work at height takes place using powered access equipment. This isn’t just best practice—it’s a legal requirement under various safety regulations like PUWER (Provision and Use of Work Equipment Regulations 1998) and the Work at Height Regulations 2005, HSE, 2023, OSHA, 2024.

A comprehensive MEWP Risk Assessment answers key questions:

• What hazards are present?

• Who is at risk and how?

• What control measures are in place or needed?

• What is the likelihood and severity of each hazard?

This process is especially critical because MEWPs are often used in unstable, elevated, or busy environments, making them prone to a variety of risks, including falls from height, collisions, electrical contact, tip-overs, entrapment, and more.

Risk assessments must be site-specific and task-specific. A generic one-size-fits-all document won’t cut it. You need to consider the location, equipment type, personnel, and nature of the work being performed.

Done properly, a MEWP Risk Assessment not only enhances safety—it demonstrates due diligence, keeps you compliant, and protects your team.

Identifying Hazards in MEWP Operations

The first—and arguably most critical—step in a MEWP Risk Assessment is identifying potential hazards. These can vary depending on the job, environment, and MEWP type, but some common categories include:

1. Falls from Height

Falls remain the leading cause of death in the construction industry, and MEWPs are a major contributor if not handled properly. Operators and occupants can fall from the platform due to sudden movements, failure to use guardrails, improper harness use, or platform overloading.

2. Overturning or Tip-Over

MEWPs can become unstable if placed on uneven ground, overloaded, or used in strong wind conditions. Even a slight slope can change the center of gravity dramatically, causing the entire machine to topple over.

3. Entrapment and Crushing

This often occurs when operators are maneuvering the lift near ceilings, beams, or walls. If not carefully managed, the user can become crushed between the platform and a fixed structure.

4. Electrical Hazards

Using a MEWP near overhead power lines without proper clearance is an enormous risk. The platform can conduct electricity, putting both the operator and ground crew at risk of fatal shock.

5. Collision with Objects or People

This includes moving into vehicles, structures, other machines, or pedestrians. It’s especially common in tight indoor environments like warehouses or outdoor construction sites.

6. Weather-Related Risks

High winds, heavy rain, snow, or ice can impair visibility and control, increasing the risk of falls or overturning.

When identifying these hazards, a walk-through of the worksite, review of operational history, and input from experienced operators can offer crucial insights. You also need to review manufacturer guidelines and load charts for the specific MEWP being used.

The goal isn’t just to create a long list of “what could go wrong.” It’s to understand which risks are most likely and most severe, and to decide what actions can eliminate or reduce them to an acceptable level.

Assessing Risk: Likelihood and Severity

Once hazards are identified, the next step is to assess the risk level associated with each one. Risk is usually calculated by analyzing two main factors:

• Likelihood: How likely is it that this hazard will lead to an incident?

• Severity: If it does happen, how serious will the outcome be?

Many safety professionals use a risk matrix to score hazards (e.g., on a 1–5 scale). A hazard that’s very likely and could cause fatal injury would be rated higher than one that’s unlikely and would cause minor discomfort.

For example:

From this, safety managers prioritize control measures accordingly. You’ll often hear terms like:

• High Risk: Immediate corrective action required. Consider job suspension.

• Medium Risk: Action needed before work continues.

• Low Risk: Acceptable with routine controls and monitoring.

This step ensures that you’re not just acknowledging hazards, but quantifying them, so that everyone understands where the true dangers lie and how urgently they need to be mitigated.

Remember, risk assessments must be dynamic. As job conditions change—such as relocating a MEWP or altering task duration—the risk level can increase, requiring reassessment.

Implementing Control Measures

After identifying and assessing the risks, the next priority is putting control measures in place. A solid MEWP Risk Assessment will specify practical ways to either eliminate or minimize each identified hazard.

Safety best practices often follow the Hierarchy of Controls:

1. Elimination – Remove the hazard completely. Can the task be done from the ground instead of using a MEWP?

2. Substitution – Replace the MEWP with a safer alternative like scaffolding or tower platforms, where appropriate.

3. Engineering Controls – Install physical barriers, use outriggers or stabilizers, ensure proper ground leveling.

4. Administrative Controls – Implement work procedures, MEWP permits, training programs, spotter roles, and warning signs.

5. Personal Protective Equipment (PPE) – Harnesses with lanyards, helmets, reflective vests, and insulated gloves.

Example Control Measures

• For Fall Risks: Ensure guardrails are intact, use fall restraint systems (not just fall arrest), and inspect the anchor points before use.

• For Tip-Overs: Always perform ground stability checks, adhere to manufacturer load limits, and use outriggers with spreader pads.

• For Entrapment: Equip MEWPs with emergency stop buttons and entrapment prevention devices like anti-crush bars.

• For Electrical Hazards: Maintain the OSHA-recommended 10-foot clearance from power lines and consult utility companies when working nearby.

It’s also critical to document all control measures within the risk assessment. That way, supervisors and operators alike know what precautions are in place and why they matter.

Training and Competency Requirements

No matter how robust your MEWP Risk Assessment is, it’s meaningless if the people operating the equipment are untrained or unqualified. That’s why training and competency are vital parts of the risk management strategy.

What Does Competency Mean?

According to the International Powered Access Federation (IPAF) and OSHA standards, competency means having:

• Adequate training on the specific type of MEWP.

• Familiarity with the model being used.

• Practical experience and understanding of risks.

• Physical and mental ability to operate the equipment safely.

Operators must receive formal training that includes both classroom instruction and hands-on evaluation. Many jurisdictions require certification renewal every 3–5 years, depending on local legislation.

Ground staff and spotters should also receive awareness training to understand the movement patterns, blind spots, and emergency procedures around MEWPs.

Training Programs You Can Trust

• IPAF PAL Card Certification: Recognized globally for MEWP training.

• OSHA MEWP Safety Training: Mandatory in the U.S. under CFR 1926.453.

• CITB Training (UK): Includes MEWP operation under CSCS schemes.

Investing in proper training not only reduces risk but also improves efficiency and minimizes equipment damage or downtime.

Emergency Planning and Rescue Procedures

Even with the best risk assessments and control measures, emergencies can still happen. That’s why every MEWP Risk Assessment must include a clear emergency response and rescue plan.

What Should Be Included?

• Emergency Lowering Procedures: Who knows how to bring the platform down manually?

• Rescue Equipment: Is there harness rescue gear on site?

• Response Time: How quickly can emergency services reach the site?

• Communication Plan: Are radios or phones available to alert supervisors?

A typical rescue plan should cover situations like:

• The operator collapsed while at height.

• Entrapment or entanglement.

• MEWP malfunction or battery failure.

Rescues should never rely solely on emergency services. The Work at Height Regulations 2005 (UK) explicitly state that rescue must be planned and practiced in advance HSE, 2023.

Conduct regular drills, and make sure every team member knows their role in an emergency.

Documentation and Legal Compliance

Your MEWP Risk Assessment isn’t just a safety document—it’s a legal one. Authorities like OSHA, HSE, and other national regulatory bodies may request it after an incident or during inspections. It must be written, dated, signed, and reviewed regularly.

Here’s what should be documented:

• Site address and description.

• Task summary and duration.

• Identified hazards and risk ratings.

• Control measures implemented.

• Names and signatures of responsible personnel.

• Date of assessment and next review schedule.

Failing to document or review your assessment can result in heavy fines or criminal liability in case of serious injury or death.

For example, OSHA citations for fall protection violations routinely exceed $14,000 per incident OSHA Penalties, 2024. In the UK, corporate manslaughter charges may arise where clear negligence is shown.

Keep your documentation in both digital and physical form, and store it with other site safety records.

Final Thoughts: MEWP Risk Assessment Saves Lives

If there’s one takeaway from all this, it’s that a MEWP Risk Assessment is not a formality—it’s a fundamental duty of care. It covers more than hazards—it encompasses your people, your procedures, your plans, and your commitment to safety.

In a world where one mistake at height can end a life, the time you invest in thorough, site-specific risk assessments makes all the difference.

So, before that boom lift goes up, pause. Ask yourself:

• Have I identified all possible hazards?

• Are the risks evaluated and controlled?

• Is everyone trained, equipped, and ready?

• And do we know what to do if things go wrong?

If you can confidently answer “yes,” then you’re not just compliant—you’re a safety leader.
