The ultimate guide to towers and low level access equipment

Do you own a tower or are you about to use one? Or maybe you’re buying or hiring a new tower? Find it in our tower guide and read more about the training you’ll need, the standard it should be certified to (with third party verification), and all the paperwork you’ll need to hand. This is must-read information for anyone who buys, hires, owns or uses towers or low level access equipment, or is responsible for safety in the workplace.

MOBILE ACCESS TOWERS

Straightforward but versatile piece of access equipment that can be assembled and dismantled quickly and easily, with a built-in means of access and collective fall prevention in place throughout. It can only be a freestanding, single bay structure with four legs and wheels. It has only one working platform at a time and can reach a working height of 12m indoors and 8m outdoors. Generally made of aluminium or GRP (fibreglass), the mobile access tower is a familiar sight in workplaces across the world.

To use this tower safely, you’ll need:

TOWERS ON BASEPLATES

The key feature differentiating these towers from an EN 1004-1 mobile access tower is that it is not mobile because it has baseplates, not wheels.

To use this tower safely, you’ll need:

TIED IN TOWERS

The key feature differentiating these towers from an EN 1004-1 mobile access tower or a freestanding BS 1139-6 tower is that it is tied into a supporting structure, and is not mobile or freestanding.

To use this tower safely, you’ll need:

  • Access Tower Specialist training
  • Tower certified to BS 1139-6
  • The current instruction manual for the tied tower
  • Design for the tie
  • Competence in using ties
  • To display information at base of tower
  • A risk assessment and method statement

STEPPED TOWERS

Can be used on a stairway, a spot where access is often tricky, but also in other places where the ends of the tower will be at different heights. Often used for painting and decorating, maintenance and repair and overhead installations. Also known as towers on stairways, stairway access towers and towers on stairs. Can reach a freestanding working height of 12m indoors and 8m outdoors.

To use this tower safely, you’ll need:

CANTILEVER TOWERS

Have a platform projecting from the side or end, so it’s used for overcoming obstacles like stairwells, window apertures, riser shafts or porches. Can reach a freestanding working height of 12m indoors and 8m outdoors.

To use this tower safely, you’ll need:

TOWERS WITH BRIDGES

Two or more towers with a bridge between them, which creates a long, uninterrupted platform area with a clear space below. Useful for a whole host of tasks, such as aircraft maintenance, where you’re working above any type of obstruction or need to leave an access route for vehicles or pedestrians. Can reach a freestanding working height of 12m indoors and 8m outdoors.

To use this tower safely, you’ll need:

LINKED TOWERS

Two or more towers joined together that can provide long, uninterrupted platforms at more than one level. Most often used to span the facade of buildings, so work such as painting, plastering or replacing windows can take place. Sometimes called facade towers. Can reach a freestanding working height of 12m indoors and 8m outdoors.

To use this tower safely, you’ll need:

LARGE DECK TOWERS

An arrangement of towers and platforms that have been joined together both at their sides and ends to create a spacious working area. Useful for those who need to access a whole ceiling, for example for painting or electrical work. They can be mobile if needed. Can reach a freestanding working height of 12m indoors and 8m outdoors.

To use this tower safely, you’ll need:

HIGH LEVEL TOWERS

Towers outside of the height limits of EN 1004-1. Can be freestanding up to 16m indoors or tied up to 20m (indoors or outdoors). Always on baseplates. No more than 3 loaded levels.

To use this tower safely, you’ll need:

  • Access Tower Specialist training

  • Tower certified to BS 1139-6 

  • The current instruction manual

  • To display information at base of tower

  • To produce a risk assessment and method statement

TOWERS USED AS A MEANS OF ACCESS

Towers built specifically to gain access to another place e.g. a flat roof. Must be tied in, built on baseplates and aligned with the step-off point. Can reach a working height of 12m indoors and 8m outdoors.

To use this tower safely, you’ll need:

  • Access Tower Specialist training

  • Tower certified to BS 1139-6

  • The current instruction manual

  • To display information at base of tower

  • To produce a risk assessment and method statement

HIGH CLEARANCE TOWERS

Towers with special frames to allow access through the base of the tower. May be used on footways. Used most often on towers with bridges or linked towers. 

To use this tower safely, you’ll need:

  • Linked Towers for Users or Towers with Bridges for Users training (or, if you’re using a single bay tower and the instruction manual permits a high clearance frame to be used, you can do this with Towers for Users training)

  • Tower certified to BS 1139-6 

  • The current instruction manual 

  • To display information at base of tower

  • To produce a risk assessment and method statement

NON-STANDARD TOWERS

A bespoke structure designed to fit around the needs of a site – however tall, wide or awkward it may be. Should only be assembled and dismantled by a qualified Access Tower Specialist.

To use this tower safely, you’ll need:

  • Access Tower Specialist training (or book a PASMA Hire & Assembly member)

  • Tower conforms to BS 1139-6
  • Verification report and design certificate

  • Assembly, use and dismantling plan

  • To display information on safe use at base of tower

  • To produce a risk assessment and method statement

LOW LEVEL WORK PLATFORMS

Often called podiums, pulpits, room scaffolds or podium steps. Provide a stable platform for one person carrying out tasks at heights of under 2.5 metres. Lightweight, easy to manoeuvre, fold away for easy storage or transportation, and have collective fall prevention built in. 

To use this tower safely, you’ll need:

  • Low Level Access training

  • Equipment certified to BS 8620

  • The current instruction manual

  • A risk assessment and method statement
