IPAF Categories Explained (3a and 3b)

For anyone new to powered access equipment, IPAF categories can be difficult to understand at first. Two of the most widely used categories within the construction industry are IPAF 3a and IPAF 3b. Both of which apply in regards to Mobile Elevating Work Platforms (MEWPs) but each covers a different type of access machine and a different way of working at height.

Having the key distinctions between these IPAF categories explained helps operators select the right equipment for the task, complete the correct training and work safely on site. Having the appropriate IPAF qualification also helps employers meet safety requirements while reducing the risks associated with working at height.

What Is IPAF Training?

IPAF stands for the International Powered Access Federation, a recognised organisation that promotes the safe use of powered access equipment across many industries. IPAF training courses teach operators how to safely inspect, operate and work from MEWPs through a combination of classroom learning and practical assessment. After passing the course, candidates are usually awarded a PAL Card that lists the IPAF categories they are qualified to use.

This training is ideal for construction workers, maintenance teams, warehouse operatives, facilities management staff and contractors who regularly work at height. Many employers ask for IPAF certification because it shows that operators have completed approved training and understand safe working practices. Selecting the correct IPAF category is important as different MEWPs are designed for specific tasks, environments and operating conditions.

What Does IPAF 3a Mean?

IPAF 3a: Mobile Vertical Platforms

On the one hand, IPAF 3a refers to Mobile Vertical MEWPs that are built to raise operators directly upwards in a controlled and stable manner. This category includes various pieces of equipment like scissor lifts, vertical lifts and other similar platforms that travel vertically while the operator stays inside the work basket.

These platforms are commonly chosen for indoor projects where safe vertical access is required. Typical applications include electrical installations, ceiling work, warehouse maintenance, internal construction and office or commercial fit-out projects. Because they are designed to move straight up and down, IPAF 3a machines are ideal when operators need to move vertically rather than horizontally.

What Does IPAF 3b Mean?

IPAF 3b: Mobile Boom Platforms

On the other hand, IPAF 3b covers Mobile Boom MEWPs that are designed to give operators greater flexibility when working at height. Machines in this category include cherry pickers, articulating boom lifts and telescopic boom lifts. Their extending boom arms allow users to reach both upwards and outwards.

IPAF 3b equipment is regularly used for construction work, external building maintenance, steel erection and sign installation. It is particularly useful when operators need to work around obstacles like buildings, roofs or other structural features and difficult-to-reach areas.

IPAF 3a vs 3b: What Is the Difference?

Do I Need IPAF 3a or 3b Training?

The right IPAF training depends on the type of MEWP you will be using. Operators working with scissor lifts and other vertical access platforms will normally require IPAF 3a training. Those using boom lifts or cherry pickers will usually need IPAF 3b certification. Many employers encourage operators to complete both 3a and 3b training, providing greater versatility on site and allowing them to safely operate a wider range of MEWP equipment.

Why Is IPAF Training Important?

IPAF training plays an important role in ensuring operators can use powered access equipment safely and confidently.

Improved workplace safety

IPAF training helps reduce the risks linked to working at height by teaching operators safe working practices. It also helps them understand machine limitations, potential hazards and the correct procedures for using MEWPs safely.

Legal and employer requirements

Employers have a responsibility to ensure workers operating powered access equipment are competent, properly trained and aware of workplace safety requirements. 

IPAF certification helps demonstrate that operators have received recognised training.

Better Career opportunities

Holding IPAF certification can improve employment prospects as many construction, maintenance and facilities roles require trained MEWP operators. It shows employers that candidates have the skills needed to work safely on site.

What Happens During IPAF 3a and 3b Training?

Each course covers essential knowledge before moving on to hands-on machine use and assessment. IPAF 3a and 3b training combines classroom learning with practical experience.

Theory training:

The theory section introduces operators to MEWP categories, health and safety responsibilities, machine controls and hazard awareness. It also covers the importance of completing pre-use inspections before operating equipment.

Practical training:

During the practical element, candidates learn how to carry out machine checks, operate controls safely, manoeuvre equipment and position MEWPs correctly. This training also includes emergency procedures that instill confidence and prepare operators for unexpected situations.

Assessment:

At the end of the course, candidates complete both a theory test and practical assessment. These confirm their understanding and ability to operate MEWPs safely and effectively.

How Long Does IPAF 3a and 3b Training Take?

The time required to complete IPAF 3a and 3b training depends on factors such as the operator’s existing knowledge, practical experience and the number of categories being covered. Combined MEWP operator courses are typically completed within one to three days, allowing candidates to develop the necessary skills through both classroom-based learning and practical sessions for comprehensive confidence.

Be aware that course length may also vary depending on individual requirements, training progress and the equipment being used.
