Working on scaffold towers: what you need to know

Posted on 1st Jun, 2026 | By Lorretta Tatham

Working from height carries serious risk, and the more complex the access equipment, the more important it is that it is set up, inspected and used correctly. When scaffold towers or mobile towers are assembled or used incorrectly, they can lead to serious injury, falls from height or even structural collapse.

Scaffold towers are commonly used across construction, maintenance, painting, external repairs and industrial works. When used properly, they provide a stable working platform at height, but safety depends on proper planning, risk assessments, inspection and training.

What are scaffold towers and when are they used?

Scaffold towers are temporary access structures that allow workers to carry out tasks at height from a secure platform. They are often used when ladders or stepladders are not suitable because the work requires more time, movement, tools or materials.

Common uses of scaffold towers

Scaffold towers are typically used for painting, cleaning, building maintenance, inspections, construction work, roofline repairs and external repairs. Before each job, carefully plan how you intend to use the tower and address any potential safety issues before work begins.

Things to consider include the site location, the length of time the scaffold tower will be in place, the intended use, the number of boarded lifts, the maximum working loads, the number of people using the scaffold, and the type of access to the scaffold.

Mobile tower scaffold safety

Mobile scaffold towers are designed to be moved around the site, offering flexibility for short-term or changing work areas. However, mobile tower scaffold safety depends on the tower being used on firm, level ground with wheels or castors locked before work begins.

Never move a mobile tower while people, tools or materials are on the platform. Ground conditions, nearby hazards and weather should always be assessed before the tower is used or moved.

How to erect scaffold towers safely

Knowing how to safely erect a scaffold tower is essential for anyone assembling, altering, dismantling, moving, or using this type of access equipment. Always follow the manufacturer or supplier’s instruction manual and do not assume every tower system is the same.

Step-by-step safe erection process

Before assembling a scaffold tower, check that all components are present, compatible and free from damage. The instruction manual should be available to all operatives erecting and using the tower, as well as the person supervising the work.

Where relevant, safe systems such as 3T (Through the Trapdoor), and AGR (Advanced Guardrail) should be followed. Guardrails, braces, platforms, stabilisers, locking systems and access points must all be correctly fitted before the tower is used.

Common erection mistakes to avoid

Common scaffold tower safety mistakes include working on a platform without guardrails, standing on an unprotected platform during assembly or dismantling, using damaged components, failing to lock wheels, building on unstable ground or missing key braces and locking mechanisms.

If defects affect the structure or the tower’s safe use, do not use it.

Working within height and load limits

Every scaffold tower has safe working load limits and maximum platform height restrictions. These limits must not be exceeded. Consider how many people will use the scaffold, what tools and materials will be taken onto the platform and whether any additional requirements or restrictions may affect safe use.

Scaffold tower safety checklist and inspections

A scaffold tower safety checklist helps ensure the tower is safe before use and remains safe while work is underway.

Pre-use safety checks

Before working on scaffold towers, check:

• The tower is on firm, level ground.
• Wheels or castors are locked.
• Guardrails and toe boards are fitted.
• Platforms are complete and secure.
• Braces and locking mechanisms are correctly fitted.
• Access routes are safe.
• Components are not damaged or defective.
• The tower is suitable for the task and working load.

These checks should be completed before use, after moving the tower and after any change that could affect stability.

Risk assessments before working at height

Risk assessments should be carried out before all work on towers to identify hazards and determine the control measures needed. This should include ground conditions, surrounding obstructions, nearby vehicles, overhead hazards, weather, access requirements and the erection, alteration or dismantling process.

A suitable risk assessment helps ensure the scaffold tower is the right access solution for the job.

Ongoing checks during use

Scaffold tower safety does not end once the tower has been assembled. Conditions can change throughout the day, particularly on busy or changing worksites. Towers should be checked regularly, especially if they are moved, altered, exposed to bad weather or used by multiple workers.

Scaffold tower safety equipment and best practices

Using the right safety equipment and following good practice can significantly reduce the risk of accidents when working at height.

Guardrails, toe boards and platform safety

Never work on a platform without guardrails. Guardrails help prevent falls, while toe boards reduce the risk of tools or materials falling from the platform. Full platform protection should be maintained at all times.

PPE for scaffold tower use

Personal protective equipment may include safety helmets, safety footwear and high-visibility clothing. PPE should be used alongside proper planning, correct tower erection, inspection and safe systems of work.

Environmental and ground conditions

The nature of the ground conditions or supporting structure should always be considered before use. Soft ground, slopes, uneven surfaces, strong winds, wet conditions, overhead cables and nearby traffic can all increase risk.

Training and compliance for scaffold tower safety

Anyone involved in assembling, dismantling, moving or working from scaffold towers should receive suitable training. Browns Safety Services offers a Scaffold Towers for Users Training Course for those using this type of access equipment.

You can also view our wider Access Equipment Courses and Health and Safety Courses to support safer working practices across your business.

FAQs

Do scaffold towers need to be inspected before use?

Yes. Scaffold towers should be inspected before first use, after assembly, after being moved and at regular intervals while in use. Checks should include guardrails, braces, platforms, locking mechanisms, castors and ground stability. Damaged or defective components should never be used.

What is the safest way to erect a scaffold tower?

The safest way to erect a scaffold tower is to follow the manufacturer’s instructions and use recognised safe assembly methods such as 3T (Through the Trapdoor) or AGR (Advanced Guardrail). All guardrails, braces and stabilisers should be fitted correctly before the tower is used.

Can scaffold towers be moved while someone is on them?

No. Mobile scaffold towers should never be moved while workers, tools or materials are on the platform. Before moving the tower, the area should be checked for hazards and the platform fully cleared.

What PPE should be worn when using scaffold towers?

Suitable PPE may include safety helmets, safety footwear and high-visibility clothing. PPE should support safe working practices but should never replace proper tower erection, inspections and risk assessments.

Why are risk assessments important when working on scaffold towers?

Risk assessments help identify hazards before work begins. This may include unstable ground, weather conditions, nearby traffic, overhead obstructions or unsafe access. Completing a risk assessment helps ensure suitable control measures are in place to reduce the risk of accidents.

What are the most common scaffold tower safety mistakes?

Common mistakes include missing guardrails, unlocked wheels, damaged components, unstable bases and exceeding height or load limits. Working on unprotected platforms during assembly or dismantling is also a major cause of falls from height.
